For Growers[+]

One of our best sellers, Black Rabbit Foot is very easy to grow. It takes approximately 10 to 14 weeks to finish a 4 inch pot from a 72 cell. Most of tropical ferns can tolerate higher light level than perennial fern. It still needs protection though! Black Rabbit Foot fern requires a minimum of 9 hours of light per day ranging from 1500 to 2000. Unlike White Rabbit Foot Fern, Black Rabbit is photoperiodic. It grows slower in short days and flushes as daylight gets longer.

The quality of the light is another important factor that affects healthy plant growth. For light protection, white poly is preferred over clear poly as it distributes light more evenly. With adequate ventilation, most tropicals are happy with 50% to 60% shade. One good way to test your light level is to put your hand above the plants during the mid of the day. If you can hardly see your hand’s shadow your light level is adequate. If not, you may want to increase or decrease your shade. Unlike White Rabbit, Black Rabbit is photoperiodic. It grows slower in short days, flushers as daylight gets longer.
Black Rabbit Foot Fern reaches its maximum growth rate at soil temperatures between 70°F and 85°F.

Temperatures outside this range will slow growth. Unlike White Rabbit Fern, Black Rabbit is cold sensitive. Try to keep the temperature above 40F during the winter, otherwise it may damage the plants.
Black Rabbit Fern like well-drained soil. Keep the soil consistently moist, but not soaking wet. Black Rabbit fern roots are susceptible to root rot when the soil is overwatered. Ebb and Flood or drip irrigation are ideal as they help keep the foliage dry, thus reducing foliar diseases. In outdoor and shade house settings, water overhead early in the day or use drip irrigation so that the foliage has a chance to dry out before nightfall.

When well cared for, ferns have very few diseases and pests. Caterpillars, fungus gnats, aphids and scale can become a problem. However, they are easily treated with your state’s recommended pesticides. Do not use copper-based products on ferns.

To supply all nutritional needs of ferns, well balanced fertilizers such as 20-10-20 or 20-20-20 need to
be applied. Rates of 150-200 ppm nitrogen are sufficient. Some growers have experienced success with a lower constant feed rate, combined with a slow-release fertilizer. Most varieties prefer pH levels from 5.5-6.5. Make sure your fertilizer also contains micronutrients.
