I have 5 weigela two 1 gallon and three 2 gallon pots in my garage, madly leafing out. As we are still having temps dropping below freezing at night, I am worried about putting them outside. Anyone have any info? All the web searches I've seen so far say, 1; they should be planted in the fall, 2; they should get full sun, mine are going to get afternoon sun as they're going on the west/northwest side of my house! These will be foundation plants. They are Sonic Bloom varieties Pure Pink and Red.
