I've got a problem with my Mini Blue lavender . I live up here in Toronto, Ontario, Canada. Just planted it this summer, at the beginning of June. I gave it a little pruning before I planted it on the ground. I've read that pruning it would give you a bushier plant but up to now it's kinda scraggly looking with just a few branches. There's some new young shoots growing out of the woody branches but it seems very slow growing compared to my other Mini Blue. I also noticed that the old leaves are turning yellow and curling brown at the tips. Is it dying? Did I overwater it? I only water it once a day during hot days. We did get a huge down pour last Friday. I've attached some pictures so you can see what I mean.
I'd really appreciate it if someone could help.
