New to growing heaths and heathers
I'm glad gardenweb has a forum specifically for heaths and heathers.
I just purchased seeds for 5 heath species (e. glandulosa, e. mammosa, e. versicolor, e. baccans and e. plukenetti) from a site with very reasonable prices (Fine Bush People). Tomorrow I'm going to buy e. vagans, e. cinerea, e. x stuartii, e. carnea, e. tetralix and a couple of calluna vulgaris cultivars from Heaths and Heathers.
Please tell me: 1) how far apart should I plant these different species so they won't cross-breed, 2) are these suitable for growing in zone 7a and 3) what's the best way to acidify my very alkaline soil. Could I just fill the plant hole with peat moss rather than the soil I took out?
I'm fairly new to gardening in general. I hope you don't mind the questions. Thank you in advance.
