One Site Said Mandevillas Need 6 Hours Of Full Sun And You Say Otherwise. Which Is Correct?

Question

I bought 3 mandevillas and planted them in a flower box – part of my house with very little direct sun. They weren’t flowering so about 3 weeks later I put them in large containers and set them in the sun. Now I don’t know where to put them. Can you help? Thanks.

Answer 1

Mandevillas need full sun to part shade. But in North Carolina, where it is so hot and humid, they appreciate some shade in the afternoon.

I think our article got confused with indoor/outdoor care. To grow it indoors, mandevilla needs bright, indirect light.
