How quickly do ferns spread?
In a month or two, small, green plants should appear. Thin them to about 1 every 3 inches. Check the container regularly and keep the soil moist. It may take another 6 to 8 weeks for little fronds to appear.
Do ferns spread on their own?
Most ferns spread quickly, and some grow quite large. Know their habits, sizes, and spreads before planting. The larger ones resent disturbance once they are established, and moving them may sacrifice their vigor for years.
How far apart do you plant ostrich ferns?
Space them 3 – 4 feet apart and 3 – 4 feet from other plants. They will spread rapidly and fill in the gaps very quickly. Plan on dividing them frequently to prevent them from taking over the entire garden. Ostrich ferns do best in full or partial shade.
How do you stop ostrich ferns from spreading?
If ostrich ferns are spreading in flower bed plantings, you can slow ostrich fern spread by establishing well defined garden bed perimeters. This is most commonly done by chopping into the outer edge of the border with a sharp shovel or spade.
Which fern spreads fastest?
Like all ferns, Ostrich ferns are plants that will spread fast. Ferns will hit the spring time and burst into action, they will grow quickly and they will also spread relatively quickly as well. Of course this doesn’t happen overnight but do be aware of your ferns spreading.
How long does it take for ferns to multiply?
Depending on the kind of fern, it may take two to six months after fertilization for the first fronds to appear. Usually, gardeners and greenhouse producers don’t reproduce indoor ferns from spores.
Do ostrich ferns come back every year?
An ostrich fern’s first priority is to establish a hardy root system. Sometimes the fronds begin to grow and then die back several times during the first season. Once established, the plant spreads easily through underground rhizomes and will soon fill in the space provided.
What grows well with ostrich ferns?

How do I get rid of bracken ferns?
Two herbicides are recommended for bracken control: asulam (Asulox) and glyphosate. Recommended dose rates for overall application are: Asulam 11 litres/ha: Glyphosate 5 litres/ha. Asulam is selective and has relatively little permanent effect on underlying vegetation, but it will kill other ferns.
