This week the plants are also in the greenhouse at night. It is still a little too cold outside but they are bigger now so I think that they will be okay.
Every day I check up on them to see if the leaves are still in the correct position, away from the plant it's stem. If the leaves are blocking the light from the stems I tie them down with some rope and a clothespin.
The leaves of my Fat Banana aren't doing so great as u can see on the picture. Why is my plant doing this and what should I do about it to make it stop?
