I'm growing a bunch of trees in pots and have been keeping them in the yard. A storm with high winds is expected (~20mph) and as I bring some items indoors (e.g. a flag, light pots hanging from a railing), I wonder if I should do something for the potted trees.
Right now I brought some of the younger and more delicate (grafted) potted trees into an enclosed porch, and I laid the larger potted trees gently down on their side. I'm hoping this will prevent wind from blowing the trees over (not gently) and in case any overhead branches fall on them, the damage may not be as catastrophic to their long-term growth.
Is there a standard practice for preparing outdoor potted nursery plants for tornado and hurricane conditions?
