Thanks for the suggestion.. you guys are way more experts in growing fruit trees that I am.. I appreciate the comments.. sorry to take away from the original posting..
Yeah, the whole hill is pretty bad.. but most of my 30+ trees (about 20-25) are on there.. have no choice.. most of my backyard place to plant is a big slope.. have three and a half rows of drip lines installed with a timer at the hose.. maybe I took it at an angle, but I do add compost (dr. earth organics 9 and steer manure) and dynagro liquid into each 'hole'.. so it's dark in the inside, just around the base of the tree.. maybe I didn't add enough? I usually add about 3 shovel full of compost .. I was planning on adding more compost and fertilizer this weekend.. is it a good time? I hear that adding fertilizer (compost or foilar) every month from November to March is good? That was my current plan.. every 3 months to dump 3 shovels of compost for each tree, and then every month or two spray the foilar.. Thanks.
Oh, the sugar apple was planted in April 2014 (April 30)
here is the original picture (the picture above was taken last weekend - I take a picture about every month so I can compare).. how is the performance you think of the growth? Did I do a good job so far? Just to quickly get back on topic.. yeah, my annonas are still 95-99% green (including this sugar apple), so they haven't gone dormant yet.. I think the only thing 'yellowing' in my yard is the jujube tree.. Otherwise, everything else still has fruit or still slowly growing..
