girliemac i will try and help you with what i know about your fern.it sounds like its just stressed from lack of water. is your fern in direct sun? if so move it into the shade.maidenhair ferns are very delicate and require a good amount of shade to grow well. maidenhair ferns are slow growing
.they grow best in zones
4 through 9.
The maidenhair fern like all ferns. requires partial to full shade and moist soil all the time.maidenhair ferns are mostly grown in shade gardens. or in hanging baskets.This fern is fairly easy to care for. needing only a good amount of shade and well drained soil that is kept moist.
most ferns prefer a good deal of humidity. misting ferns regularly is the best way to do this.
for dealing with stress.if they run out water they might die. always keep them moist.for use a soil that holds plenty of moisture yet provides some root aeration peat moss plus perlite works great for these plants
. i would move it into the shade and water real well and keep it moist.it should grow back but it might be slow to do so you might lose the part that has curled up because of lack of water.hope this helps.your friend in gardening.mike57
