I'm growing Sakura again this year but didn't realise I only had two seeds left in the packet. Fortunately both germinated on the window sill then I moved them into my mini greenhouse inside the main one, but one of them only has one true leaf. Will it survive?

It should survive, as long as you keep it warm enough to keep growing.

You can always use the sideshoots as cuttings and increase your crop later, GG!

I've never grown Sakura, but assume that the process with an F1 will be the same as a 'mainstream' tom!
