I have a new, small Twisty Baby shrub/tree on my patio and I am wondering if this should be protected from the months of rain we get between October and June here in the Pacific NW?
You Twisty Baby Locust is hardy to USDA Zone 4 (-30°F) so it can easily handle your winter. If it is in a pot, the pots should be sunk at least half way into the ground for the winter. More on your plant here:
