After several years I have a couple of new birds nest ferns growing. I feel like a new parent. However, this is on a rental property and I’m concerned that the fernlings have decided to grow just above each other with the lower very close to the mulch / ground line. I fear they might just get destroyed or covered over by uncaring / unaware tenants.
When is it safe to transplant or is it not safe to? Leaves on big one are 4 in number and about 100mm long. Smaller is about 3 leaves and 20mm in length.
