Harts tongue ferns
So I’m wondering if any of you have faced a similar problem. I recently planted some harts tongue ferna that were flourishing and doing extremely well. I noticed however over the past few days that more than one of them has started wilting, the leaves look limp and the plants look at though are dying. I have checked the soil which is damp and not overly soggy... could this just be some form of disease. Any help appreciated!!
