Hello all, I posted a few months ago about some yews we planted in April of this year. We bought them from a local grower. We rented a tiller, added some bone meal and watered well over the summer. (I don't know if links are allowed here, but this is the thread: Hedges: - Straggly yews) They started to look a bit straggly to me but I kept the faith. Unfortunately in the last two weeks, their colour has started to change....a deep brownish gold starting on the tops; it started with one (the one that got the most sun). Can anyone offer any insight? I don't see any pests on them. Thank you!
