My bonsai has begun to droop. The leaves look healthy but its just dropped within a day. i've water and applied food to the soil. any body have any suggestions??

Maybe underwatering?　Otherwise I'm not sure; deciduous arent my specialty...:(

what kind of tree is it?

i think its better if you re-pot it. the problem might be in the roots. but be careful because if the tree is already weak it might die. make sure you don't put too much water also.

Could be a light saturation issue...could be that its just not getting enough light exposure or improper exposure...if the leaves are green but limp to me it just seems like it might be acting like its wanting to go dormint...which is temp or light for me......

But check the root ball also......Hate to go there but agreee it could be that your roots are growing enough that they start to over crowd and then start to decay...youll have to pull the root ball out, check it and possiably cut about 1 quarter to half the bottom of your root ball off.....
