I have a south west, sun drenched Terrace apartment for this beauty and in just 4 days it's gone from perfection to looking like it's going downhill fast. I bought it at the Vancouver Tree sale last year. Bought a large pot which it's been in for 11 months. When I purchased it it was half the size. 10 days ago the blossoms were just about to open, and 4 days ago I was really enjoying the beauty of this plant. Over the last 4 days I've notice MAJOR whiling and yellowing of new leaves. I've checked for bugs and fungus but can't find anything. The new buds and new tiny leaves are yellow and I have no idea where to go from here. Each day it gets worse! About a week ago a noticed tiny suckers coning up, about 5 and cut them off and I gave it a tiny amount of fertilizer ( 10-8-6 ) That the box says for Roto & Azaleas but the plant store person assured me this was also okay for Lilacs. I gave it a bit a more water, (it had been a week since the last water, and it ran though. The soil doesn't feel wet at all, but not super dry either. Clearly, it's on a bad path, but I have no idea where to take it from here, but feel something must be done. Any advice would be very helpful! Thank you in advance!
