I am wondering if I’ve placed my maidenhair fern in a inappropriate spot. It gets approximately 1.5 hours of direct sunlight and I noticed it seemed a little peaked. I don’t know if it’s because I just planted it or if it’s too much sun.

Answer:
Hi Robin, We are based in Sydney, Australia – so our knowledge of Salem is not much good. There are many many different types and species of maidenhair too. Some maidenhairs like the Australian species Adiantum aethiopicum will grow in full sun PROVIDED THAT it gets daily watering. All maidenhairs need a constantly damp soil or they will die back. Direct sunlight for 1½ hours is OK but, direct sun around midday can be challenging for them. My best guess is that yours needs more water daily. BUT local knowledge is always best – so ask local gardeners or plant nursery people. Don
