|We moved into a new home 2 years ago which already had a hydrangea planted on the SE side of the house (up against the basement wall). I have yet to see it bloom. This year, the foliage was killed by a late frost, but has made a good comeback and is now about 2.5 to 3 ft high. The soil seems to be fairly well-drained on this side of the house, and it receives 5-6 hours of direct sunlight in the heat of the day (11am -5pm). Another factor involved is that it is surrounded by a variegated periwinkle that grows taller than any I've ever seen (up to 2 ft.). Should I transplant it -- if so, when and to what environment?
