Oak saplings

Question

Saplings are in big pots indoors but they do not look too healthy.
What can I do?

Answer 1

This can be due to many reasons. Could you include pictures? This would help me to better see what the problem is.

Over or under-watering, lack of light, and lack of fertilizer are common reasons for the tree to be unhappy.

If you can include a picture, and detail on the care of these then I will be more than happy to help.
