Q: I have planted lots of seeds in trays this spring, ready for potting on and planting out as the temperatures warm. However, I've noticed green mold forming on the soil in a number of the trays. What has caused this, and should I be concerned?
A: Growing plants from seed is super rewarding, but there are a few problems that can arise during the process, from leggy seedlings to the development of mold on the soil. The latter is generally caused by excessive moisture and humidity, according to John Negus, a gardening expert.
