Greetings!
I've been working on establishing a small backyard nursery. On this day, I have over 240 privets, cotoneasters and plums, 2 months old (since rooted), developing great. Here's my problem. I planted them in my garden, so they'd develop faster, on 40 square metres, which was by my calculations (considering species I chose, except plums, which are planted elsewhere) enough space for them to grow there for a year and then replant them into big pots. What I'd like to know is, what soil nurseries use for starter trees? By starter trees I mean plants you let grow freely, doing only necessary prunings. Is it ordinary bagged gardening soil, or is it some kind of mixture? As plants are not being trained, my guess is it should be water retentive . Thank you in advance.
