methods for trees restoration

When a tree weakens, what to do?

Why do trees weaken?

Lack of nutrients, or illnesses. Lack of nutrients requires soil analysis, and usually the deficit is found withing the color of the leaves, although many deficits look alike. The major illness that causes tree to weakens is instead wood rot...At least in dry areas, whereas in colder climates bacteria can be worse, however bacteria and viruses don't have solutions nowadays...

First approach, fertilizers

Plants are full of antioxidants, and other compounds that deter different kind of illnesses. Be it either for lack of nutrients or illnesses, applying fertilizer is always the first course of action. What fertilizer? As I said before it kind of needs proper soil analysis, however most fertilizers sold, provide a good mix of the most important elements. Composite or simple? Both is the correct answer. Instead of providing 100% in-organic, consider a 1/2 split or a 2/3 split in favor of organic fertilizers.

"I tried putting fertilizers but it hasn't had any effect"

When you apply fertilizer on large terrains, you are betting that the fertilizer reaches the plant. There are a few problems with this bet:

If the plant manages to absorb the nutrients, it will have a chance at deterring or isolating pathogens and resume its normal growth.

Second approach, infiltration

Large plants, have had a long life and might have survived different waves of pathogens each wave weakening the plant a little bit. Arm yourself with a drill, a mix of in-organic fertilizer, mycorrhizae and trichoderma, and a syringe. Lets assume that you tried fertilizers, but the plant doesn't respond, maybe it has sprouted new branches from its base, but its top is still slim and rachitic. You have to find out were small (or large) pockets of wood rot reside. Usually if the rot is large, you would remove all of it with a chainsaw, however this interventions are quite stressful for the plant, and almost never remove the rotten wood completely. Your goal with infiltration is to build a trait of canals along the full stump of the tree up until half its trunk. This way you have a complete coverage of potential wood rotting pockets. How large should the canals be? It depends on the size of the tree, start with half a centimeter. In order to achieve 100% coverage, canals must be drilled all around the tree. Their distance and their numbers also depends on the tree size. Always drill along the concavities of the bark, to avoid damaging the younger and active xylematic conduits. plants-infiltration Once canals are drilled, its syringe time. Preparing the mixtures:

canals along the stump base.

Repeat this process at least twice (once in spring, once in autumn). The second time, however, only use myco and trico, splitting the canals 50/50 between them. Don't put myco and trico in the same mix. The goal of infiltration is to restructure the plant xylem to work around pathogens by building an armor with synergistic fungi. There should be some results within 2 years.

Third approach, grafting

Roots and foliage are always in balance. When one grows, the other follows.

Results depend on how vigorous the cultivar (and the applied rootstocks) are, in general at least 3 years.

Forth approach, heavy weights

This is the most invasive approach, you have to perform a deep plow-through all around the tree (at least 1 meter deep) as close to the stump as possible. Your goal is to cut all the deepest roots that you can, such that the tree is forced to sprout new ones if it wants to stay alive, boost its chance again with a mix of mycorrhizae and trichoderma, this time you would be applying them on a wider scale, with shoulder carried pump and spraying all around the dug terrain over the uncovered stump. After spraying cover with soil again, ideally mixing it with some breach, in order to keep the soil porous and preventing it from compacting too much, such that new roots will have an easier time growing. deep-plow

The plant should respond to this last attempt in a few months, either positively or negatively. If the outcome negative, sorry, its time to consider planting something else.
