Propagation of Brickellia amplexicaulis B.L. Robins. var. amplexicaulis
Brickellia amplexicaulis B.L. Robins. var. amplexicaulis, commonly known as Clasping Brickellbush, is a native plant of the southwestern United States and northern Mexico. The plant grows up to 2-3 feet tall and thrives in dry and rocky habitats.
Propagation by Seeds
Propagation of Brickellia amplexicaulis B.L. Robins. var. amplexicaulis can be carried out through seeds. The plant produces small, dry, and flattened seeds that can be harvested when mature. The ideal time to collect seeds is in mid to late summer when the seed heads start to turn brown.
The seeds of Clasping Brickellbush require a period of cold stratification to break their dormancy. They can be stratified for 4-6 weeks under refrigeration before sowing. Sow the seeds in a well-draining potting mix and cover them lightly with soil. Water the soil and keep it moist until germination. The seeds usually take two to four weeks to germinate.
Propagation by Cuttings
Brickellia amplexicaulis B.L. Robins. var. amplexicaulis can also be propagated through stem cuttings. Take semi-hardwood cuttings in summer from the current season's growth. Cuttings should be 4-6 inches long with at least two nodes. Remove the leaves from the bottom half of the cutting and dip the cut end in rooting hormone.
Insert the cut ends of the stem cuttings into a well-draining potting mix and firm the soil around the cutting. Water the cutting and keep it in indirect light until roots develop. It takes 4-8 weeks for the cuttings to develop roots and reach transplantable size.
Propagation of Brickellia amplexicaulis B.L. Robins. var. amplexicaulis can be successful with proper care and attention to detail. The resulting plants will provide beautiful blooms to enhance any garden or landscape.
Disease Management
Brickellia amplexicaulis B.L. Robins. var. amplexicaulis, commonly known as Clasping-leaf Brickellbush is susceptible to some plant diseases such as leaf spots, powdery mildew, and rust.
Leaf Spots: Caused by a fungus, leaf spots cause discolored, brownish, or black spots on the leaves. The best way to manage this disease is by practicing good garden sanitation. Remove and discard any infected plant parts, especially fallen leaves. Avoid overhead watering to keep the foliage dry.
Powdery Mildew: This fungal infection appears as a white or gray powder on the surface of leaves, stems, and flowers. To manage powdery mildew, use a fungicide, prune infected areas, and improve air circulation.
Rust: Rust appears as orange or yellow rust spots that cause a powdery rust appearance. To manage rust, prune the infected areas and use fungicidal sprays to prevent the spread of the disease.
Pest Management
Squash Bugs: These bugs damage the plant by sucking sap from the foliage, causing the leaves to yellow and wilt. Squash bugs can be managed by handpicking or using insecticidal soap.
Borers: The larvae of moths or beetles can burrow into the plant, resulting in wilted leaves and damaged stems. To prevent borers, avoid over-fertilizing the plant and ensure you follow proper garden sanitation to get rid of any debris that could harbor the larvae.
Spider Mites: These pests leave small yellow dots on the foliage, causing the leaves to appear mottled. To manage spider mites, keep the surrounding area free from debris and use insecticidal soap spray.
