Cheilanthes

Cheilanthes require consistent watering, but their needs must be managed carefully to avoid diseases. The soil must stay consistently moist, and never soggy. They prefer a humid environment and will appreciate the extra hydration they receive from regular misting. As with most plants, they should be watered less in the winter but kept from drying out. You may also consider a humidity tray to provide extra humidity to prevent the fronds from drying out.

Cheilanthes thrive best in bright, indirect light with several hours of indirect natural light, preferably from a south or west facing window, and is able to tolerate a few hours of morning sun. They need to be out of direct sunlight, as intense midday sun can cause burning their delicate leaf tips. A mixture of shade and adequate light within a room should allow the plants to thrive and be generally healthy.

These plants can thrive in temperatures between 59-77°F (15-25°C) and will do best in an area of the house where the temperature is fairly close to room temperature. They can tolerate cooler temperatures, down to 40 °F (4 °C), but they must be protected from frost. It’s best to move the plant away from any heaters or air conditioners during the cooler months to protect the fronds from burning.

Cheilanthes are tropical plants which need a higher humidity level than most houseplants. The air should not be too dry, since this may cause the fronds to become crispy and dry out. Regular misting with a spray bottle is recommended, along with a humidifier to keep levels higher when the air is very dry. Placing a tray of water near the plant can also help to increase the humidity.

Cheilanthes thrive best in a light, well-draining soil. A mix of two parts peat moss, two parts loam, and one part vermiculite or perlite will provide good drainage and adequate aeration. To ensure the soil is not compacted, add in small amounts of organic material such as compost or worm castings.

Cheilanthes should be fertilized twice a month during the growing season with a balanced, organic fertilizer. Feed a diluted mixture of organic fertilizer with liquid feed to avoid burning the roots, as large doses of fertilizer can damage the plant. If the plant is not in a growing period, such as during winter, fertilization should be skipped or reduced to just once a month.

The most common pests associated with cheilanthes are aphids, mealybugs, thrips, and spider mites. Aphids and mealybugs can be treated with an insecticidal soap or neem oil, and thrips and spider mites with an insecticide. To prevent pests from forming, regularly check for signs of infestation and ensure that your plant is not placed in water-logged soil or in any hot areas of the house. Additionally, reduce the amount of spraying and misting to prevent pests from finding a source of water.

Cheilanthes should be repotted every two or three years—it will appreciate a larger pot as it grows. If you find that the plant is overrun by pests, it's best to repot it in new soil. Choose a pot that is just slightly larger than the one used before, and use a well-draining potting soil for best results. If needed, add peat moss to help with drainage and lighten the soil.

Cheilanthes should be lightly pruned for shape when necessary. Pruning should be done with clean, sharp clippers or scissors and should be done at the end of the growing season. Avoid over-pruning, as the plant may become weak. When possible, prune only a few fronds and allow new ones to grow.

Mulching around the base of the cheilanthes can help to keep roots cool and retain moisture. Use a light mulch such as sphagnum moss or pine needles, but be sure that the top of the plant is not covered with mulch to avoid the risk of rot. Be sure to add mulch in moderation, as too much can reduce aeration and drainage.

Cheilanthes are most commonly propagated through the division of established plants. Duringrepotting, carefully lift out the fern and divide the crown into two or more parts. Each division must have root systems and some foliage. Place the divisions in the prepared pots and lightly press soil around the outside of the root ball. Water lightly and place in bright, indirect light. In the right conditions, the plant may take a few months to become established.

Cheilanthes may need some form of support as it grows larger. A light stake in the center of the pot can help to keep the plant upright and keep the fronds from splaying. Additionally, metal wire can be used to keep each individual frond upright.

Cheilanthes do not require a distinct rest period, although they may go dormant during colder months of the year. During this time, reduce the amount of watering and allow the fern to focus on regrowing its foliage when temperatures warm up again.

Cheilanthes spp. are generally considered to be non-toxic to both pets and humans.
