when you have starts Dawn, let them grow until they have 2 or 3 pairs of leaves, then pinch the growing tip out, this will produce 2 new stems, carry out the same procedure when they have2 or 3 pairs of leaves. You can carry on doing this as much as you like, but remember it will delay flowering 6 weeks for singles, 8 weeks for doubles and 10 weeks for triphylla types. Kath:)
