Propagated Plants slooow to grow
This one is really baffling me. I propagated several mopheads four years ago from cuttings, a Pia, a noname lacecap and two Endless Summer. They rooted fine, overwintered in my garage and I planted them into the ground the next spring. Partial shade, deep watering, everything they normally like and respond to well. Well, for the past three years they have not grown much past the initial cutting size. The Pia has four stems now, all with two sets of leaves and about 5" tall. The others are about the same, three and four stems each, healthy leaves, but all about five to six inches tall... what gives? Why aren't they growing better and get more size? Is this normal growth rate for a cutting propagated hydrangea? What are your experiences with rooted cuttings? Should I grow them for a season or two in pots before planting them back into the ground?
