I have a 3 years old cherry plant, about 2 metre tall. Just noticed there is a wound: https://imgur.com/3Df7pC5 Wonder what can be done to fix it if any? Here in Australia is mid-winter.
A master of Bonsai from South Africa once told me, that any wounds or breaks in living trees can be fixed by applying white wood glue on the affected area. Which the tree will eventually dissolve in time, after it heals. As it's mostly starch, resin, and gum, (all natural extracts from other trees).
Oophhh…that is a deep wound. Just leave the trunk be. It will work on its own to protect the wound. Try to be a bit more diligent with protecting against high winds, weather issues . Place a surround ground safety zone around the planted trunk area using stones, bricks a couple feet around the tree to protect against more damage to the trunk. Then add a few inches of mulch around the trunk , but leave a space of 6-8” away from the trunk . This will help prevent damage from burrowing animals and insects while allowing air to the trunk area preventing rot to the bark. Sometimes even 3-4 stakes around the base of the tree about 2 feet out and around the trunk then wrap with chicken wire around the stakes will protect the young tree from deer and other munching critters.
It looks to me like canker. I've seen it on my cherry trees. https://extension.oregonstate.edu/sites/default/files/documents/em9007.pdf It's similar to anthracnose on apples trees. https://treefruit.wsu.edu/crop-protection/disease-management/apple-anthracnose/ I cut off affected branches and burn them.
I can't promise that it is canker. It's my thought, though. I have had it on main stem and I left it alone. It does't always kill the tree.
Sure...I think your suggestion was correct...it looks like canker. I will try to wrap it with cling wrap and tape to protect it hope it helps.
I did some wrapping and after 2 months, now is starting spring here in Australia. Found some green buds sprouting and the wound "looks like" a tiny bit healing and seems still alive.
It’s a leave it alone wait as see situation. I had trees recover from deep wounds over the years. Better not to cover it or spray with anything. Allow the tree to heal the area.
I recently repositioned my 4 year old mango plant, just noticed again a wound hole on its stem, about 1 cm in diameter.
In the ways of repairing or rooting or general health of the merisytem plants do some pretty cool things. Like me getting a scar I guess, but since the meristem is only tree rings thick some gardeners trim the torn area of the maristem with a razor blade or sharp knife so the cellular structures are uniformly exposed in an effort to promote uniform growth and minimize scarring as it hopefully closes. I dont know much about prosthetics or providing a structure like the pith would be replaced with something like mortar internally or externally. I imagine zinc plated expanded metal might be a good snack for a plant should it come to rusting in place. I have bolts holding together some hateful but huge bradford pears and those washer and nut holes healed well. I have not had great luck closing the wounds from a dead or broken tree limb. Size matters? Maybe I try some mesh next time for kicks. My wanderings aside, the main problem you have is the water reserve in the pith above the wound is gone. Maybe it can heal but plan on checking later but before planting time so you make a plan on replacement that is good timing for the transplant.
