Sun/shade- growing morning glory

Question

Hi, I’ve started growing morning glory indoors. I am planning to transport the box out on my balcony when it gets a bit warmer. The seedlings are already growing taller in it.
I know they need full sun but can a box be in almost full shade while the leaves are crawling up on the trellis and will get full sun exposure?

Answer 1

Sun drives photosynthesis which allows morning glory to grow quickly. It will languish and sulk while in shade. There are degrees of shade, however. Deep dark shade is a problem. Bright shade, meaning no direct sunlight but lots of ambient light, may be OK temporarily. I would not be surprised if the lower leaves yellowed and dropped after several weeks in shade.
