How do tree ferns grow?
Tree ferns are slow-growing architectural plants with spreading fronds above a thick trunk. They make striking plants for a sheltered, shady garden.
Will my fern live through winter?
Deciduous ferns do not stay green in the winter. However, if you have chosen ferns suited to your zone, they will still survive the winter just fine. When fronds start dying back in the fall, cut them back. Ferns can be kept warm with a mulch covering for the winter months.
Do ferns come back after a freeze?
When only the fronds freeze, the fern will recover easily, but if the roots freeze it has less chance of recovery. Check for frost-damaged roots after a hard long freeze. Cut off the frost-damaged roots and repot in fresh potting soil. If the roots are black all the way through, the fern won’t recover.
How do you protect ferns from freezing?
Bed sheets, drop cloths, blankets and plastic sheets make suitable covers for vulnerable plants. Use stakes to keep material, especially plastic, from touching foliage. Remove the coverings when temperatures rise the next day. For a short cold period, low plantings can be covered with mulch, such as straw or leaf mold.
