Looks fine to me although it could probably stand to be potted and unbound from the stake.

Protect from scorching heat/sun while young...if you get a heat wave. Keep soil moist...and feed often with low-dose of liquid fertilizer. Young trees have a small target zone with small root system.

Actually it's recommended not to fertilize when newly planted, at least in the 1st month, but I guess it depends on the roots systems. The root systems on the trees I planted last month was mostly poor except for the peach. I've barely given some miracle grow but I did that as much to help new leaves grow that were eaten by the deer.

I wonder is there a 'root fertilizer'? Or do you have to have created compost already on hand to get roots on newly planted to grow best?

Is it normal for my mexicola avocado tree to have little brown lines on the trunk from bottom to top? Also I notice some leafs have holes on then, and the new ones that are growing look reddish
