Dryopteris augescens (Link) C. Christens. var. lindheimeri (C. Christens.) Broun, also known as Lindheimer's wood fern, is a commonly cultivated species in the southeastern region of the United States. It is a deciduous fern that grows up to 4 feet tall and is known for its attractive, finely dissected fronds.
Spore Propagation
Propagation of Dryopteris augescens var. lindheimeri can be done through spores. Sow the spores on a sterile surface, such as nutrient agar, and keep them at a temperature between 70-75°F and high humidity. After several weeks, the spores will produce tiny green heart-shaped prothalli, which will eventually grow into fern plants.
Division Propagation
Another common propagation method for Dryopteris augescens var. lindheimeri is through division. This method involves dividing an existing clump of ferns into smaller pieces and replanting them in new locations. Spring and fall are the best times to carry out division propagation. Dig up the clump and use a sharp knife to divide it into smaller sections, making sure each section has a healthy root system. Replant the sections in well-drained soil and keep the soil moist.
Cultivation from Bulbilils
Dryopteris augescens var. lindheimeri can also be propagated through bulbils. These are small, bulb-like structures that form on the leaves of the fern. The bulbils can be removed and planted in a well-drained soil mixture. Keep the soil moist and place the bulbs in a shady spot until they have established themselves.
Overall, Dryopteris augescens var. lindheimeri is fairly easy to propagate through spores, division, or bulbils. With care, these methods will yield healthy new plants that will thrive in the appropriate growing conditions.
Disease Management
Dryopteris augescens (Link) C. Christens. var. lindheimeri (C. Christens.) Broun is a species that is susceptible to several diseases, including:
