i have several young fruit trees on my farm.
the permie people i read when i started said trees and hugelulture didnt go together because the soil sinks so much. so i planted them in the path between the piles.
i planted 3 plum trees and was gonna train them into an arch over the path. 1 lasted about 3-4 years.
so i have a little wrought iron arch between them. 2 years ago, i took the arch away. the tree fell over.
the had gooey fungus, which i was spraying for.
all that taught me a ton about trees. including that if i plant them on top of the pile, the sinking will let their anchor roots grow healthy.
all the trees on the parkway around here are at least a little low. then people, i mean assholes, do things like put a 2 high used railroad ties about their entire parkway, burying 3 50 year old trees.
and plant shit like daylillies 3' thick. etc.
i was friendly w a dude in the railroad tie building. condos.
he is really a preening ass. he has 2 sad little what passed for a bulldog these days. bought one, rescued the second.
so sweet. he parades them up and down the block every hour on the hour.
people stop him and pet the dogs all the time, which is what he is after. but he never would let them off the leash, or even let is slack because he claimed he was teaching them not to jump. except he wasnt. they went nuts trying to love me up. and in this bullshit storm, i really could have used that extra bully love.
anyway, talked to the dude, showed him, etc. memorial day weekend.
i nagged him for a while. he said he talked to the board, and he was "steering the boat"
i told him to grab an oar.
still nothing. but he doesnt strut past my house anymore. so i will leave him to karma. funny how thick a disguise some people put on to hide that they are really hollow assholes.
anyway, one more tip. my favorite garden tool is a nozzle they call i sidewalk sweeper. but mine is named street sweeper.
if it is really deep, dig it out some. dig a big hole, a well, at the dripline, and just watch they rest off.
it's fun to do on a hot day. i love water works, and moving dirt around w/o a shovel. you wont nick up the roots.
