I planted a "President Grevy Lilac" bush about a month ago and it's not doing real well. First we live at 10,000 in the mountains of Colorado with a short growing season and our soil is mostly decomposed granite. I've read several opinions from keep moist to don't water more than a few times a month???
We dug an area about 3 times the size of the pot it came in and filled around it with miracle grow garden soil and sheep peat with top soil so it would have something around it but granite but after about 1-1/2 weeks it has a wilted look plus it isn't a healthy green - it looks weak. I'm wondering if I should fertilize with some "Plant Tone"? I've heard that is good - but the guy at the nursery said not to worry about fertilizing the first year. I've mulched it thinking maybe it's too dry.......because it's been windy and hot - I watered it pretty heavy about 5 days ago and it stayed pretty moist. Still looks wimpy - don't know what to do? Any ideas?
