Young Chestnut Tree Problem

Question

These chestnut trees are about 8 months old started from seed. I don’t know exactly what kind they are. The leaves started getting brown patches on them. Hopefully I can get some help in identifying what the problem is. Thank you Mike

Answer 1

They look like they need to be moved into larger containers. Chestnuts are large trees and will need to be accommodated for growth. They also need acidic soil which they may not have. When you upsize, mix the soil with about 1/2 sphagnum peat moss and 1/2 potting soil. You also can buy fertilizers for acidic plants that will help.

Brown edges also can indicate too much or too little water. Increasing the amount of soil will help with water retention.
