The problem will be the roots growing right through the spaces between the wires and the wire cutting into them as they thicken. If the fruit trees are on dwarfing rootstocks - and not mini- or genetic dwarves the same issue may eventually be seen with the cherry in particular also. Because sweet cherry is a large growing tree, so that even when on a dwarfing rootstock it will still grow over 10 ft. tall. With a proportionate root spread.

take a hand trowel.. and dig down in one spot. AND LOOK AND SEE WHATS GOING ON .... report back ...

also.. while you are there.. find out how far down the hardware cloth goes ...

did you bare root the tree.. do you have any idea where the roots were .... e.g. if your hardware cloth goes down 3 inches.. but the roots are 6 down.. whats the worry????

btw.. while you are out there.. find the root flare.. and insure that it is exposed ...

im not sure i see yours in this pic ..

ps: looks extremely dry.. for a tree planted only a month ago.. where are you... big city name .... plan on getting some good mulch next spring ... or sooner if you can find anyone selling any in winter .. wherever you may be ...

All except certain desert adapted tree species root near the surface. Regardless of what they might also be doing farther down.

yeah.. its usually pot culture.. which forced roots down the side of the pot.. to give the APPEARANCE of the trees having a proclivity to rooting deeply ... i will add my rather over-used maple pic below to show you the usual pancake form of mature roots on a silver maple ...

anyway... protect the plant from ce3rtain edible death.. and forget about the potential fencing issue ... in fact.. ..in a year or 3.. you can probably graduate to another type of protection.. and just remove the cloth ... its not like you are going to have to look at it for the rest of your life ... there are other ways to protect slightly bigger trees ...

dont forget my water questions ....

maple roots ... im going to track down and kick that guys butt for calling this pic over used.. who does he think he is ... of wait.. it was me.. i hate when i get in fist fights with myself.. its rather embarrassing when it happens in public ...

oh man... its all right there i the title.. ornamental plums are extremely short lived trees .. thier lives counted in decades .... and if you get ten years out of one... you will be very lucky ... ive had 4 of them over the years .. bought one just about.. wait for it.... every 10 years.. the purple foliage was worth it ...

it usually succumbs to gummosis and black knot ... neither of which are treatable.. or worth treating for ..

so.. add that to all the rest.. and i doubt your tree will live long enough to die form the cage issue ...
