You wouldn't do anything. The plant does it on it's own.
Thats alot of threads man.. Calm down!!
hey bro thanks peace and budsWith your plant outside you are relying on mother nature. There's nothing you can do but wait. The only way I know of to force flower outside is to cover with something to block the light. I don't grow outside, so do some searching around the outdoor section and see what you can find.
