Crappy Soil- repot and save your baby!
Re-potting several months ago may have been not advisable because of weather and seasonal change, any replanting/potting should be done in January when things are hibernating. If the location is sunny and the pot is movable to a shady spot then this should be done as soon as possible, then the odd thing is Water water water to saturate and prepare for a removal from the planter. The watering fills the plant and suspends it so it has less shock after being messed with, then remove from the pot and if the root ball has caked soil on it dunk in a bucket. Keep it under water and carefully remove the soil considered a full repotting procedure. Go to the nursery and get an soil mixture that is Not a potting mix with all the peralite white stuff, you want a mixture that has sand and forest humus and be sure to test it- most mixes have clay that is currently killing your friend because when you water it forces out the air then the plant droops from Overwatering.
test the mix by wetting a handful and squeezing then tapping and it should fall gently apart but be like a sponge, then put some in the bottom of the pot and saturate then put the plant in then add soil compressing softly with a closed fist. half way up water again and continue untill done and then water filling the top three times. on the third then wait thirty minutes and check like it is a cake using a long knife or skewer and it should come out moist, then dig a little and all should be moist like when you tested the soil when you purchased it.
Keep in shady spot for at least this summer and feed and if there are any flowers Remove them so the energy goes to the roots, check stems even if they are bare bending slightly and if pliable they are Alive!
