Pruning
Pruning is necessary to maintain the shape and size of the Geranium harveyi Briq. plant. It is best to prune the plant after it has finished blooming in late summer or early fall. Cut back the old stems by around half their length. This not only helps the plant look good, but also encourages new growth. Regular pruning will keep the plant bushy and avoid legginess.
Propagation of Geranium harveyi Briq.
Geranium harveyi Briq., also known as Harvey’s Geranium, is a beautiful perennial plant that can be propagated through various methods. There are three main propagation methods that can be used for this plant, including seed propagation, cutting propagation, and division propagation.
Seed propagation
Seed propagation is the most popular method for propagating Geranium harveyi Briq. Seeds can be collected from the plant in autumn before the first frost. To increase the chances of germination, the seeds can be soaked in water for 24 hours before planting. Sow the seeds in a well-draining seedling mix, and water regularly until the seeds germinate. To ensure the best germination results, keep the seeds in a warm and bright area, but out of direct sunlight.
Cutting propagation
The second propagation method is cutting propagation, which involves taking cuttings from the plant and rooting them in soil. Cuttings can be taken from the plant in late spring or early summer. Choose healthy stems that are not too old and remove the leaves from the lower part of the stem, leaving only a few on top. Dip the cuttings in rooting hormone powder, and plant them in a well-draining potting mix. Water regularly and keep the cuttings in a shaded area until they develop roots.
Division propagation
The third propagation method is division propagation, which can be used to divide a mature Geranium harveyi Briq. plant into two or more parts. This method is typically done in spring when new growth appears. Carefully dig up the plant, and separate the roots and stems into multiple sections. Each section should have several stems and a healthy root system. Plant each section in a well-draining soil mix, and water regularly until they establish new roots.
Overall, Geranium harveyi Briq. can be propagated through seed, cutting, or division methods. Each method has its pros and cons, so choose the method that works best for your situation and practice proper care and maintenance to ensure a healthy and robust plant.
