I planted some blackberries , my favorite berry, watered them faithfully every day for a week or so, had to take a trip,
came back a week later, and green branches were nearly two feet long in every direction. Sudden burst of growth . And I wasn't watching when it happened.
Same thing here. Can't go cross-eyed trying to watch this thing grow. Relax. Knowing what I have, check back in Feb., July,
and next Sept, then the year after that. Prune a few branches every now and then so it'll grow better.
