Try putting the pictures in as a comment. That usually works.

I'd been trying but all I get is a blank page afterwards

keep gently excavating.. until you find the root flare ...

i dont like the one that id smaller width where the soil was against it ..

ken

I don't like it either xD but I'm wondering if it's dangerous to expose that part now that autumn is coming

expose what part.. the root flare ...

it may be dead by spring.. if you dont .. whats to lose???

btw.. where are you ... big city name ...

usually fall is a great time to plant trees .. for most of us ... so why should little gentle excavation hurt??

Not knowing your general location in the world makes it hard to give you an accurate answer.

Try reducing the size of your photos to around 1600 x height. Large photos don't load that well.

Your first photo your tree doesn't look very good and may as well be replaced. What kind are they?

Your second photo with the dark shadow makes it difficult to see what's going on.

Take some better pictures, shrink them down, so we can see better.

Thanks.

Uhh just realised my photos failed to go through

Alright so the attempt no. 100 worked. I live underneath a mountain in Sarajevo, Bosnia and Herzegovina. This specific tree is prunus cerasifera nigra. The tree was buried 9 inches above the flare and the height of the trunk is 6.5ft. Last year I purchased same trees from the same nursery and it looks to me as they bury the graft in soil. These trees are growing fine and show no struggle, but I'm trying to make sure it stays that way as some of our trees died from what seems to be the consequence of planting too deep and volcanoing with compost

Thanks for your effort!

About the only thing you can do is expose the root flares on the tree to a proper depth. This may involve adding a 'well' around a larger tree, if needed to lower the ground enough to do that.

A smaller, more recently planted tree can be dug and raised by placing soil underneath to reseat and raise the root flare.

This all should be done during the trees dormant season when the tree is not actively growing.

HERE's a video showing trees with a problem root flare issue (safe site).

Some trees may be too far gone to respond to raising the root flare, only time will tell over the next few seasons.
