Heart Rot: The bridge between ecology and horticulture

I’m a lifelong student of pruning. I LOVE learning, observing, and theorizing over tree physiology and applying newfound thoughts and theories with curiosity and gratitude every pruning season. Earlier this week, I saw yet another article talking negatively about heart rot, which motivated me to finally finish my essay on the subject. In this essay I’ll talk positively about heart rot, tree physiology, pruning and orchard ecology.

Heart rot art: Texas? Peen? Elephant?

“That’s heart rot. The tree’s health is in decline” replied one horticulturalist to the above photo. “Hey, that’s heart rot…you had better apply a fungicide spray” replied someone else. And my response? Have you ever pruned an old tree?!

When it comes to pruning, I almost exclusively work with old trees and I see this a lot. Yes, it’s heart rot. No, I do not believe this tree is in imminent danger or even in decline, which is surprisingly a stance that not many people take. And so we’ll start there.

What is heart rot?
Heart rot is what happens when the pith of a tree (the center) starts to decay. The instigators of this core decay are fungi that get into the heartwood through wounds, broken branches, pruning cuts, etc. In a healthy tree, they only stay in the heartwood, which is the part of the tree that is not considered alive. It is often thought of as the dumping grounds for the tree, where minerals and older tree rings go to rest.

As fungi gradually work their way through the heartwood, the tree becomes hollow over time. In the timber realm, these fungi are considered harmful pathogens because they reduce the value of a log. Hollow logs= less money. This way of thinking, that fungi are harmful pathogens and hollow is unsaleable, somehow worked its way into horticulture, only this time… Fungi= harmful, Hollow=structurally unsound/sick/dying. So very rarely have I seen someone in the horticultural realm step back on the subject of heart rot to see the forest for the trees, which is why I’m writing this essay.

What is heart rot doing to the tree?
Way back in 2007, when I was doing a lot of forest inventory in Louisiana, I had to core all sorts of trees in order to assess their health and age. Often, after removing the core, I’d get sprayed with stinky water, spurted with methane from the hole I created, or witness a mass evacuation of insects. Lots of life inhabited those trees and that’s because heart rot fungi slowly made way for life to be there. This concept of rot-makes-habitat was really hammered home when I helped a USDA sniper tranq some inbreeding black bears that had chosen to calve in the cavities of old cypress trees. Straight up Winnie-the-Pooh habitat, those cypress swamps. Only poor Winnie was shacking up with his cousin in this scenario and had to move.

This tree is a pollarded tree

Fast forward 11 years to 2018, when I flew to Basque France to attend a conference on pollarding. It was there, surrounded by European foresters, forest engineers and horticulturalists, that everyone had a special place in their soul for heart rot and hollow trees, something I had never encountered before. A prevailing opinion, which I now view as a bridge between forest ecology and horticulture, was that heart rot creates hollows/habitats for all sorts of fauna. In hosting this fauna, the trees become collectors of poo (feces, not the bear). This creates an incredible microbial metabolism in the tree which, when combined with decomposing heartwood full of trapped minerals, supplies a steady amount of organic fertilizer that is slowly released to the base of the tree. Since trees store growth rings in the heartwood on an annual basis, this natural process of decomposition and fertilizing is a renewable. Hollow trees provide their own compost. That’s true sustainability.

But isn’t a hollow tree a weakened tree?
The comparison I always see is that heart rot or hollowing makes the tree structurally unsound. I’m here to tell you that this is mostly an emotional reaction. In all reality (and some physics), the tree isn’t weakened at all until the trunk’s radius is 70% hollow1.

Mattheck paper cited at end of this essay

And keep in mind, that’s an un-pruned forest tree with a full crown. If the tree is pruned to allow for airflow and to correct for weight imbalances, the hollow tree is much more structurally sound. An old pollarded willow tree, for example, boasts complete structural soundness until the trunk’s radius is 93% hollow2 thanks to a radically reduced crown . This tells me that mostly hollow orchard trees (on good root systems. Eff dwarfing trees), if pruned regularly, pose very little structural threat.

What causes a hollow tree to ultimately fail?
When trees are hollow and the wind has a strong influence over them (most likely due to crown size and density), the circular trunk becomes a bit oblong. This creates a vertical crack, which is the ultimate shearing stress for the tree. Again, pruning for crown reduction in old trees really helps to avoid the development of these shear cracks.

Mattheck et al.

More explained through tree physiology.
Here’s the deal. Trees contain both sapwood and heartwood (see tree cross section picture at beginning of essay). The sapwood is the outer, living, layer of the tree that is responsible for carrying water and nutrients up to the canopy. Think of it as a bunch of tubes, or vessels (xylem), constituting the lifeline of the tree. Since this is one of the most important parts of the tree, it’s a heavy consumer of photosynthetic energy and a lot of that energy is spent on defense against pathogens (like fungi and bacteria) entering into this important area of transport.

If the sapwood is injured, the tree has an incredible and diverse defense process. One defense in particular that is easy to conceptualize is when tissues (parenchyma) outside of the vessels (xylem) cauterize the wounded vessels and separate them from sound vessels. In Malus, wounded vessels get plugged with a starchy-watery gum that is aptly named “vessel plug.” Other trees have tyloses instead of gum, and when the vessel (xylem) is injured, the parenchyma tissue grows into the cut chamber to seal it off3 .

I’m telling you about vessel plugs only to hammer home the point that sapwood has a lot of defenses that work tirelessly to keep invaders, whether from an accident or from decomposing heartwood, away from their life-transport network. This is part of the reason why maintaining a youthful vigor in a tree is important, because younger wood contains a higher ratio of sapwood to heartwood, increasing the defense capabilities of a tree on a minimal energy budget.

The higher ratio of sapwood to heartwood is also why it is better to prune younger wood on fruit trees. When pruning, the wound is much more efficiently cauterized and uses less energy.

Bonsen and Bucher


I’ll also note that the ability to cauterize, or create fast boundaries to some sort of attack, is often genetic. Look no further than fireblight tolerance in a durable apple like the Dula Beauty (triploid) compared to the sickly Esopus Spitzenburg to get a better idea of the genetic range.

Pruning larger limbs.
When I consider pruning larger limbs, the rule of thumb for me, unless a giant intervention needs to happen or I’m topworking (grafting in place), is that I often don’t cut limbs larger than 4 inches in diameter. This is strictly something I do in considering the tree’s energy. If the ratio of sapwood to heartwood goes down with age, then it takes a lot more photosynthetic energy (that starch-water mixture) to plug up a larger wound on an apple than it would a smaller wound. Add that energy expense to the tree simultaneously trying to activate dormant buds to create new growth, and even I’m exhausted. Let me be clear, though. I’m not doing this to protect from heart rot, which costs the tree relatively little energy. I’m doing this to help the tree balance its defense and growth energy.

Hollow trees in the orchard: Mycorrhizae
If you believe that hollow trees create their own compost and self-fertilize, and if you believe that pruning trees is a way to make hollow trees more stable, then let’s briefly mention mycorrhizae.

Mycorrhizae is the fungal network that is known to connect trees to other trees and allow them to talk and share resources. They connect trees to other resources by having their hyphae (or the fungal threads of mycorrhizae) grow in and around the tree roots. The roots release sugary exudates, which feed the hyphae and give them energy to go mingle. What causes a tree to release sugary root exudates? Pruning is one way, because tree branches are connected to tree roots. Once you start pruning a tree, the fine root system connected to those branches will die back. It’s not a 1:1 prune: root dieback ratio, as the root system is larger than the crown, but there is for sure some dieback.

What’s more interesting to me, however, is the confluence of fine root dieback from pruning, plant-microbe interactions from a hollowed out trunk and fungal hyphae in the soil. It’s a bit like Captain Planet; when these three powers combine, nutrient uptake and overall ecosystem health are enhanced. And this is why I’m on team ‘hollow tree.’ It’s almost as if the tree is creating it’s own “edge,” or diverse environment in which it and everything around it thrives in a wild and chaotic balance.

Final Comments (for now):

Instead of viewing hollows as condos for pathogens, view them as beneficial habitats that improve your orchard ecology. They are important refuges for all sorts of critters, from insects to birds, microbes to fungi, and maybe even a black bear (just kidding). Given how important these hollows are, NEVER! and I repeat, NEVER! Fill those holes up with concrete or bricks or anything else. Not only does it royally piss me off to ruin a chainsaw chain to some branch that was filled with concrete, but it’s not helping the tree in any way. And would you want to come home one day only to find your house filled with concrete? No.

Let’s keep an open mind to heart rot, ok? It’s performing a pretty amazing ecosystem service with no inputs from me.

NO NO NO NO NO NO NO NO NO NO NO NO NO!

Wanted: June Ripening Apples (and Pears)

IF YOU HAVE INFO ON ACTUAL TREES RIPENING APPLES/PEARS IN JUNE IN ZONE 7 OR COLDER, COMMENT ON THIS BLOG!!! 

Summer apples are rarely of interest to most apple growers and consumers. Compared to their later season kin, they bruise easily, are often described as lacking texture (or “mealy”), low in sugar, and having a very high acidity. They might not seem very fun from this brief description, and I’ll go into detail of why these apples are fun for me in a bit, but first: Light hearted stereotypes of people who find/have found summer apples to be exciting:

1.) Elderly people from New England & other places labeled “Cold as Hell”

videoblocks-elderly-couple-holding-apple-basket-happy-woman-and-man-outdoors-how-to-grow-fruits_sdoyygptl_thumbnail-full01

Picture taken from a google search

In my own personal experience, 90% of people over the age of 80 know of the Russian cultivars “Red Astrachan” and/or “Yellow Transparent” because of apple sauce. These are the first popular apple cultivars to ripen in New England and have a relatively thin skin that disintegrates when cooked down into sauce. That disintegrating skin quality, by the way, is a big factor defining a “sauce apple.” If you have to peel it before you cook it/have to use a food mill to get the peels out: It’s not a true sauce apple.

I made some apple sauce this year from an old Yellow Transparent tree in Northern VA (Apples cored, halved + Pot + Stovetop) and my tasting audience (employees of Southern States Cooperative), thought it was too acidic. I, the person who subsists on apples for months out of the year, thought it was great. But I’ve realized that my area in Virginia has lost much of its culture surrounding summer apple sauce. In New England, it seems to still be alive…for now.

2.) People alive in the early-mid 1800s

In researching early ripening apples in my home state of Virginia, I’ve run across several accounts of growers from Southern Virginia selling “Yellow May” (a June Ripening apple for them) to New York markets for a pretty penny. Turns out, before the Russian cultivars (like red astrachan and yellow transparent) hit the scene, people in the Northern states were hankering for apples in June and buying them from the South. They probably ate them, rather than making sauce, because I don’t think texture was as big of an issue as it is now (thanks, apple lobbyists).

Why am I looking for June ripening apples?

Quick answer: For animal fodder

Long answer: It is my ambition to create animal paddocks based on drop times of fruit. WHAT THIS MEANS: I will one day be able to rotate animals from paddock to paddock and have that synched with drop times. Their feed will entirely be the grass growing in the orchard and the dropped/shaken-off fruits from the next level up. I’ve done quite a bit of work/collection for the later months, but the early months are much harder.

WHAT AM I LOOKING FOR?

homepage_map

Anyone north of Virginia, in mountainous areas, or familiar with the USDA plant hardiness zone map 7a/7b*: If you know of an apple that produces in June and can get access to it/provide contact info to me, I would love to hear about it. The perfect scenario is this:

1.) I’m provided with some background info on the tree you’ve identified as a June bearing apple. This includes location, what you think it might be called, when in June it bears (early June/late June) and any other info you can find (bloomtime is something that comes to mind, but not that important). This is so I can keep notes on your selections and credit you in the future! Pictures are also a huge help.

2.) You can either take scionwood from the tree or get me the contact info so I can write/call the owners and see about getting some scionwood from this tree. I will gladly pay for your time and effort. Please, before taking scionwood, reach out to me so I can make sure we are on the same page as to what scionwood actually is.

3.) You mail the scionwood to me and I compensate you and credit you in future descriptions and work!

Other items of note:

I DO NOT CARE HOW THIS APPLE TASTES/TEXTURE/SMELLS/LOOKS. AT ALL.

I DO NOT CARE WHETHER OR NOT IT GETS BAD DISEASE (but would love to hear about this if you have info)

I DO NOT CARE IF IT HAS A NAME OR NOT

I DO NOT CARE IF IT IS GRAFTED

I DO NOT CARE IF YOU ACTUALLY HAVE A JUNE BEARING PEAR. That’s amazing, too, and I want to hear about it.

I ONLY CARE IF IT BEARS IN JUNE. Come one, come all…get in touch with me if you know of a June apple bearing in slightly colder climates.

*The reason why I ask for zone 7a/7b or colder (the lower the zone number, the colder) is so I can extrapolate. If someone in zone 5 has a first week of June apple, that could very well be a mid-late May apple for me. May apples in Northern VA are non-existant as far as I know, and I’m also very interested. The earlier the bearing, the more diverse of a diet my animals get earlier in the season. 

 

 

 

 

why I dislike the term “silvopasture”

(I was writing another essay today and found myself going off on a rant about the term “silvopasture.” I decided to remove it from my essay and make it a new post…so here you go). 

For close to a decade of my life, I was either a student of forestry or a forester throughout the US and Germany.  I studied and worked in a variety of forested environments, and eventually made the transition from forestry to horticulture. The two realms, forestry and horticulture, originally came together for me was when I started learning about the lesser-known tree and plant species which produce medicinals and food within the forest and forest edge. I became quite good at foraging for food and medicinals while on the job and the idea of managing a piece of property for fruits and nuts became much more exciting to me than managing for timber. The transition from forester to horticulturalist began when I started to transition from forager to farmer; from forest to orchard.

An orchard is an intentional planting of trees or shrubs that is maintained for food production. Orchards comprise fruit, vegetable, and nut-producing trees which are grown for commercial production. Orchards are also sometimes a feature of large gardens, where they serve an aesthetic as well as a productive purpose.

Now on to this term: Silvopasture

Silva in latin means forest or woods. Pasture comes from the latin Pastura, meaning feeding or grazing. Together, you get grazing/feeding in forest or woods.

When I first heard the term “Silvopasture,” I assumed it was the act of thinning or planting a forest for timber/firewood and beef/pork/mutton/poultry, etc production. And in some cases, it is. But I have to address the other cases where silvopasture has become a term for planting fruit and nut trees on a pasture for some form of commercial fruit and nut production and introducing animals to the scene.

An intentional planting of fruit and nut trees is an orchard. For centuries, people have grazed their animals through their orchards because it makes complete and total sense on a practical level. Animals are an integral part of management in my opinion and weird health fears and scaling up are likely to blame for the elimination of grazing.  In the rest of the world, though, animals are still in orchards and it isn’t called silvopasture. Here’s a recent photo-example from Kyrgyzstan: A dwarf apple orchard with beasts in it.

IMG_0814

Or an olive orchard with goats in it in Northern Italy:

Both of these systems pictured manage for a tree crop and a meat crop (and grass crops). No timber will come out of these systems, and prunings take the place of coppice wood (which could be used as firewood). (Note to self: Pruning vs Coppicing is an interesting topic to revisit in a future essay).

How very American of us to first remove animals from orchards on account of scale and fear, and then put them back in and rename the system.  My dislike of the name silvopasture isn’t just in the semantics, though… This renaming thing we Americans do is directing people away from sources of valuable information. Information like how to grow these trees for tree crops on a moreso commercial scale is a practice studied in horticulture rather than in forestry. Though it’s nice to have feet planted in both realms, the difference is important! I know, because I’ve worked and studied in both.

If you want to pursue growing fruit and nut trees in a field/pasture for the commercial harvest of fruits and nuts while also incorporating animals into your management and income stream, try search terms like “orchard grazing” or “hogs in apple orchards” or “cows in cherry orchards,” etc.  With this knowledge, you’ll likely get a lot more out of your time spent on google, like THIS.

Sincerely,

Eliza the ORCHARDIST

However, I did see it worded in the UK as “Silvopastoral Orchard Agroforestry,” which is totally fine because all of the descriptors and origins are there.

Heterozygosity. It’s Why I’m Concerned for Broad-Acre Permaculture

Over the last few years, I’ve watched and read of many people who have put in highly diversified, large scale orchards in the name of creating a commercial-scale food forest (or something to that extent). By “highly diversified,” I’m talking chestnuts, apples, grapes, hazelnuts, persimmons, paw paw, sea buckthorn, lonicera, black locust, etc. Some people call it “Agroforestry” while others are calling it “Silvopasture,” yet both of those systems traditionally involve the harvest of timber crops rather than fruit and nut harvests. The difference between a timber crop and a fruit crop is HUGE when it comes to planning out a landscape, and this difference alone is why I am predicting the economic hard times of many broad-acre permaculture farms. Employing some basic horticultural/orcharding knowledge to repair what has been overlooked is necessary in order to progress and evolve into a better agricultural system. This blog post is designed to air out my concerns and get people thinking about these overlooked topics in order to bring about faster innovation and success. Note:  This blog post is intended for future and potential commercial growers. Not homesteaders.

The reason why I’m predicting hard times? It’s called heterozygosity: Plants grown from seed may not exactly duplicate the characteristics of its parents. What does this mean? Well, let’s use apples as an extreme example… When you eat a red delicious apple and then plant the seeds, you will not get a red delicious apple tree.  In fact, if you plant the seeds from a red delicious, its offspring will produce entirely random results and you’ll likely get something very far from the looks and taste of red delicious. The apple might be green and tiny with a sour taste, or orange and triangular shaped with tastes of honey. The variability is huge, and that’s why we graft. Grafting is basically a form of cloning and every single red delicious apple tree grown in the world comes from the genetics of one single tree. (I’m not going to get into “sports” in this conversation).  

A small sampling of the shapes and sizes of apples, due to extreme heterozygosity

A small sampling of the shapes and sizes of apples, due to extreme heterozygosity

Diversity fuels sustainability and is a basic tenant of ecology, so planting out row upon row of the same grafted tree variety is not seen as a very ecologically-minded process. In fact, as we continue to graft the same thing over and over again (Just yesterday, I learned that 60% of all apple trees planted in New York State are Macintosh), we are hindering any co-evolution for disease and pest resistance and we growers become more reliant on chemicals to produce a crop as nature evolves around us and becomes increasingly resistant to what we throw at her.

The genetic characteristic of heterozygosity found in varying degrees across many, many tree crops is allowing  for a myriad of genetics that might stand up against the current coevolution of nature. In this light, many permaculturalists are advocating planting trees from seed in order to select for a diversity of genetics that will work with your site, climate, etc because that is one of the only ways we’ll create a truly healthy and sustainable agricultural system. Yet, this is agriculture and those of us farmers heading towards growing perennials on a commercial scale need to make a living doing this. Like, a living off the crops…not off of classes, workshops, speaking engagements, etc.

So, what’s the problem in growing food-tree crops from seed on a massive scale? Heterozygosity. You see, though you’re selecting for better genetics, you are also opening yourself up to a bunch of other unknowns about the tree…like when these fruits and nuts will actually ripen. In the case of apples, your ripening/harvesting window in certain areas can run between June and October. That’s a 4 month-long period!  Now, imagine that you just planted thousands of trees across broad acreage without paying ANY attention to when your crops will ripen. Imagine trying to harvest those crops with any sort of efficiency. Hint: It’s nearly impossible unless you have a huge crew of free labor.  And according to the Department of Labor, once your free labor has the skills to competently do a task, they must be paid minimum wage (or else you are breaking the law).

I once managed a 5 acre orchard with over 100 varieties of apples. These varieties were planted in a patch-work style across the orchard without much sense or order. During harvest, apples were ripening across the entire orchard rather than row-by-row and when I left that orchard, I learned to always clump varieties together that will ripen at the same time (or close). In doing this, you’ll save money in harvest costs, sanity, and also be able to actually provide a merchantable crop other than renting out your rows to finish your animals/other’s animals on an absurd amount of nuts and fruits.

In regular agroforestry or silvopasture systems, you are harvesting timber in addition to growing alley crops or livestock. Trees can grow at different rates, but if you planted them all at the same time, there’s a good chance you’ll be able to harvest them at the same time. That sort of planning ahead for timber crops should not be applied to tree-food crops and we need to stop pretending like it can.

A Silvopasture System For Timber

This is a fact: If you plant trees with intention of harvesting their fruit/nut crops for markets/value added without a harvest plan, you will be screwed when they come into bearing. 

In Central Asia,  edible”silvopasture” (harvesting apple/walnut trees for timber/firewood is illegal) is an integral part of their apple and walnut harvest. The basal area (term used to describe the average amount of an acre occupied by tree stems) of the apple and walnut trees in the forest allows for healthy pasture underneath the trees where livestock are grazed before and after the harvest. The results: You get an apple crop (home processing), a walnut crop (one of few ways to make money there), meat and milk products from livestock (to feed your family) AND the livestock are cleaning up the pre-harvest drops (usually full of pests), keeping the grass low for actual harvest off the ground, and eating the post-harvest drops/leaves (to get rid of pest and disease). These forests are rather broad-acre (thousands of acres) and are broken into parcels which people lease. Walnuts and apples don’t ripen uniformly within these forests, so having these small parcels leased to families ensures a complete harvest because their livelihoods depend on it.

Planning out a broad-acre planting of anything? Farmers, regenerative agriculture designers and permaculture designers heed warning.  It is very important to have your rows timed according to harvest if you or your client intends on making any money off the system. Stefan Sobkowiak of Miracle Farms has done a wonderful job of this in his permaculture orchard which has allowed for people to go in and pick a variety of different fruits from a single row. In the coming weeks, the rows change to account for ripening. He’s not on a broad-acre scale just yet and has integrated u-pick into his business plan, but it’s the same type of thinking needed for broad-acre perennial plantings.

I’ve seen a lot of pictures of a vast diversity of trees planted on contour swales, keyline, terraces, etc. People wanting to incorporate livestock into the mix have these grand visions of running livestock row by row to create fruit/nut finished meat. Now, wouldn’t that be nice if everything in that row ripened at the same time so you’d only have to send your livestock down that row once after harvest? You can also add some extra value to the scenario by listing off specific varieties (which have stories) that went into this meat.  That’s efficiency and truly forward thinking and planning.   It’s where permaculture and regenerative ag needs to be.

Some of you reading this might have this feeling of dread because you just planted out a acres of extreme, unharvestable chaos.  If you leave your landscape be, you won’t end up with the commercial perennial agricultural system you sent out to create that talks bushels per acre, yields, and everything else an investor or someone replicating your model should ask about. Instead, you’ll likely end up with a food forest preserve that you might be better off treating in the same fashion as those in Central Asia. The model of having others come in and lease parcels of your food forest to harvest isn’t a bad idea either. Perhaps some will consider this as a future model.

I’m interested in creating and using low-input management techniques to grow fruit and nuts in an ecologically savvy way that will change the face of current agriculture. I’m interested in bushels per acre, harvest efficiency, timing. When a corn-grown kid from the FFA wants to know bushel numbers and pricing for these agriculture systems, I want people to be able to present a serious and factual case for him or her to consider changing over.

How do you fix and prevent this?

Some questions to ask your landscape designer:

1.) How many bushels per acre of (insert crop) do you anticipate for harvest once this system is mature?

2.) Will these trees be planted in a way that will allow for a streamlined harvest rather than a hunt-n-peck scenario?

3.) What varieties of these fruits and nuts are you thinking of? Can you please give me harvest dates for these varieties in my area (or extrapolate)?

Tips for those of you who have an unharvestable situation:

1.) Start your research on ripening times for varieties/band your research with others/hire a consultant who can give you this information. Try to procure scionwood from people who have harvest information. There are 7500+ known varieties of apples out there. How much do you want to bet that a couple hundred of them ripen at the same time?

2.) Learn how to top-work or hire someone who is an expert to do it for you once you’ve found varieties suitable for your layout. Or, if you already have trees producing in a haphazard pattern on your landscape, start taking notes of when each tree is ripe and be prepared to top work them into a pattern that makes some harvesting sense.

3.) Planting from seed? Start reading up and learning about true plant propagation and breeding. You can get a good idea of what to plant out from your nurseryin a few year’s time with conscious breeding and innovative techniques.

4.) Encourage and support nurseries and individuals to venture off the beaten path and start really breeding/fruit exploring for low-input management techniques. Support their taking of notes.

5.) Don’t balk at these plant breeders for patenting a plant/tree which they’ve put many hours, dollars (from their own pockets) and observations  into in order to improve the agricultural system. That’s the cost of innovation. Heck, universities are doing it on tax-payer dollars.
