Cut the foliage just above the crown with a sharp pair of gardening shears. Trim the dead branches after the new growth comes in. Alternatively, you can wait until the new growth comes in to cut off the old fronds.
It's best to do this early in the season. Shear off the dead fronds near the crown to make your plant healthier and prettier. Cut the outer edges of the fronds to create a desired shape. If you don't like the way your fern is shaped, simply trim the outer edges until it's to your liking.
Use sharp scissors or kitchen shears to do the trimming. Keep in mind that the tips turn brown if you clip off the edges.
Trim a transplanted fern by half to help it thrive. When you move a fern, it may need some help getting settled in its new location. Cut back all the fronds by half, reducing the water your fern needs to support itself.
Don't worry. Once the plant is settled, it will grow back. Avoid pruning right before winter. It can be tempting to cut off dead or dying fronds at the beginning of winter.
However, those fronds help protect the root crown throughout the winter. Method 2. Cut off dead fronds as they appear. Use a sharp pair of scissors to cut the fronds. Dead fronds will be brown or black. Cut them near the base of the frond, just above the joint. You can use a sharp pair of scissors or a small pair of garden shears. Remove any fronds infected with scales. They are small, reddish brown, and flat. If the soil is moist, feed your fern with a small amount of low-nitrogen fertilizer.
The faded fronds on indoor ferns can be trimmed back any time of year, regardless of weather conditions. With outdoor ferns, do light pruning on a cool, cloudy day and avoid pruning ferns on hot, dry days. This helps reduce stress on the plant. Any heavy pruning of outdoor ferns should wait until late winter or early spring. Do Ferns Need to Be Pruned? Home Guides Garden Garden Care. Related Articles. Propagation Division The easiest way to propagate hardy ferns is by division.
It depends on the growth habit of the fern as to how it will divide: Creeping rhizomes In spring, cut the rhizome into segments about cm long, ensuring that each segment has at least one growth bud and a small root ball Pot up individually into peat-substitute based compost at the same level at which it was growing.
Bulbils A few ferns, for example some cultivars of the soft shield fern, Polystichum setiferum, develop small bulbils along the midrib of the frond.
Leaf bases This process is very effective for propagating sterile cultivars, notably those of Asplenium scolopendrium. Dig up mature plants and remove the soil prior to gently peeling off the short, dead-looking leaf bases from the older rhizomes Wash and then remove any frond or root remnants Plant 1cm apart in sterilised compost ensuring that the attachment point the green end is pointing upwards Place in a new polythene bag, inflate and seal Keep in cool conditions with good indirect sunlight and in 3 to 4 months, young fronds should be visible emerging from the newly developed bulbils Prick out into sterilised pots of compost see below and harden off as for spore propagation Spores The majority of ferns produce their spores in small heaps or lines on the undersides of the mature fronds.
Fill a 7. Place a disc of newspaper on the compost. Pour boiling water gently onto the disc until the water coming from the bottom of the pot is very hot. Cover the pot with a piece of glass or plastic, or aluminuim foil and leave until it is cold. Remove the glass and paper disc when ready to sow. Sowing the spores Sprinkle the spores very thinly over the soil surface Immediately cover the pot with a piece of clear polythene or cling film, secured in place with string or an elastic band Label the fern pot immediately with a permanent, waterproof marker pen If sowing different batches of spores, sow each pot in a different room in order to avoid cross-contamination of batches Place the pot in a cool, lightly shaded place for a month or two by which time a green film on the soil surface will be visible through the cover.
This will gradually form into distinct filmy green structures the prothalli After a further month or so the first tiny fronds will appear When fronds are visible, prick out the sporelings, in clumps, into pots of sterilised potting compost Maintain a humid atmosphere by enclosing the pot in a polythene bag in indirect light for a few days, as exposure to dry air can be fatal Midsummer sowings may well produce true fern fronds by winter, but autumn sowings may not until the following spring.

Growing guides Tree ferns Tree ferns are slow-growing architectural plants Growing guides Hosta Hostas are one of the best foliage plants for In this picture, you can see it without the haircut, showing the new fronds starting to unfurl amongst the old ones.
Cutting off the old stems after the new ones emerge is fraught with danger and requires a patient hand; the risk of severing the new fronds is high. I photographed this one partially trimmed to show you the density of the new growth, with the lush old growth still standing. In a large fern such as this one, the choice is a dense thicket of crowded fronds, or a fresh abundance of spring green. It too was starting to look leathery and tired. Maintenance of perennials makes the difference between a garden that looks worn out and sad, or one that bursts with new vibrant growth.
