Pruning Selago Hirta Choisy
Pruning is not generally necessary for Selago hirta Choisy, but you can trim the plant to your desired height and shape. The best time for pruning is after the blooming season, usually in the late fall or early winter. Use clean, sharp pruning shears to remove any dead, damaged or diseased branches. Also, remove any old or weak stems that are detracting from the overall shape and vigour of the plant. Pruning can stimulate new growth and increase blooming in the next season.
Propagation of Selago hirta Choisy
Selago hirta Choisy, also known as hairy Selago, is a small evergreen shrub that is native to South Africa. It grows up to 50 cm in height and produces beautiful white or pink flowers.
Propagation methods
There are different methods of propagating Selago hirta Choisy, including:
1. Seed propagation
The most common method of propagating Selago hirta Choisy is through seeds. You should collect the seeds when the plant is flowering, as the seed heads will turn brown and open. The seeds can be collected and stored in a cool, dry place until they are ready to be planted.
To plant the seeds, place them on top of a well-draining soil mix and cover them with a thin layer of sand or soil. Keep the soil moist but not too wet, as the seeds might rot. The seeds should germinate within three to five weeks.
2. Stem cuttings propagation
Selago hirta Choisy can also be propagated through stem cuttings. Take a 7-10 cm long cutting from a healthy stem with a few nodes and leaves. Remove the lower leaves and dip the cut end of the stem into rooting hormone powder. Plant the cutting into a well-draining soil mix, and keep it moist but not too wet. The cutting should root within four to six weeks.
3. Division propagation
Division is another propagation method for Selago hirta Choisy. This method involves digging up the plant and dividing it into smaller sections. Each section should have some roots and stems. Replant the sections into their own pots or into the ground. Water the plant immediately and keep the soil moist until new growth appears.
Whether you decide to propagate Selago hirta Choisy through seeds, stem cuttings, or division, make sure to keep the new plants in a warm and sunny location, protected from strong winds, until they have established themselves.
Disease and Pest Management for Selago hirta Choisy
Selago hirta Choisy is an ornamental plant that is easy to grow and maintain. However, like all plants, it is susceptible to various diseases and pests that can affect its growth and overall health. Here are some common diseases and pests that might affect Selago hirta Choisy, along with suggestions on how to manage them.

Removing infected leaves and spraying the plant with a fungicide can also help control the spread of powdery mildew.
Another disease that can affect Selago hirta Choisy is root rot. This can be caused by overwatering or poor drainage, which leads to the plant's roots rotting. To prevent root rot, ensure that the soil is well-draining and the plant is not watered excessively. If root rot has already set in, reducing watering and treating with a fungicide can help to manage the disease.
Pests
Selago hirta Choisy can also be affected by various pests, including spider mites, thrips, and mealybugs. These pests can cause damage to the leaves and stems of the plant, leading to stunted growth and poor plant health. To manage these pests, it is recommended to keep the plant clean by wiping the leaves with a damp cloth regularly. Additionally, using insecticidal soap or neem oil can help to control the spread of pest infestations.
Another pest that can affect Selago hirta Choisy is the whitefly, which appears as a cloud of tiny, white insects when the plant is disturbed. To manage whiteflies, use sticky yellow cards to trap the insects and reduce their numbers. Alternatively, spraying the plant with an insecticide can also help to control the pests.
