Autumn Fern: Basic Care
Autumn fern is a very undemanding plant. Some factors affecting its growth pattern have been listed below:
1. Soil Type
The soil may not be very rich in terms of nutrition but it should drain well. Usually, potting soil mixed with some humus and perlite is recommended. Adding some charcoal chips or fir bark bits ensures faster draining.
This fern needs minimal fertilization with a water-soluble fertilizer. Ideally, the fertilization should be done on a monthly basis, particularly before spring. Using slow-release fertilizers is highly recommended since this ensures sustained nutrition for the soil.
Autumn fern has very few pest-related problems. The only pests known to cause some degree of damage are scales and mealy bugs apart from the occasional problem of aphids. Maintaining proper precaution during the transplanting time ensures that pest-related problems are easily avoided. Use of pesticides is recommended in serious infestations only.
The soil should be moist throughout the year. Using lukewarm water is recommended. Misting with warm water is known to fasten the early growth.
Autumn fern is a shade-loving plant. It needs a completely-shaded area in the garden. A few hours of bright sunlight too can prove damaging. In most cases, bright sunlight can scorch the autumn fern.
6. pH Balance
The soil should be slightly acidic for best results. However, autumn fern is known to adjust to most soil types if the required supplementation with fertilizers is done.
This fern cannot survive in high-temperature zones wherein daytime temperatures are high. Autumn fern can adjust to high humidity and winter zones. It can survive temperatures between 60 and 85 degrees Fahrenheit with ease. Moderately-low temperatures with cool shade for most part of the day is best suited for the autumn fern.

This fern is famous for its horizontal growth pattern. The young fronds quickly ripen and need periodic pruning. It is advised to cut back the dead and mature fronds towards the beginning of the spring season. After the first, few months of initial growth, autumn fern spreads rather slowly. However, the growing ferns need some handling as some degree of intertwining is usually expected.
