hey guys , i think your going about it the wrong way,when you plant in spring it can set u up for a fall.
if you plant your fruit trees in late fall. the ground is allways wet ,there is no pressure of summer sun ,or having to water all the time or build fancy water works.
in the fall ,wnter,and spring allows the root ball to grow at its own speed, and tree has had 6 to 7 mts to grow without having to stress over making leaves and roots. so the next spring the tree is going grow like nature intended. thats how i do it and i dont lose hardly any trees ,in fact this is how i start all me trees. even hardwoods
