It is best to propagate Selago hispida from cuttings, which should be taken during the early summer months. The plant grows relatively slow, so it doesn't require frequent repotting.
Watering Needs
Selago hispida Sieber ex Choisy prefers to dry out slightly between watering. Too much water can lead to root rot, damaging the plant. It is important to keep the soil moist but not too wet. During the hotter months, plants may require more frequent watering.
Watering should be done from the base of the plant to ensure that the water reaches the roots. Avoid watering the leaves of the plant, as this can encourage fungal growth.
Fertilization
During the growth season, which is from late spring to early fall, Selago hispida Sieber ex Choisy will benefit from a balanced fertilizer. A liquid fertilizer should be diluted and applied monthly at half strength. Avoid over-fertilizing, as this can lead to salt buildup on the soil.
Pruning
Pruning Selago hispida Sieber ex Choisy is not necessary, but it can help to promote bushier growth. Pinch the tips of new growth to encourage branching and create a fuller plant. Any damaged or diseased leaves or stems should be trimmed off, using clean and sterilized pruning shears.
Propagation of Selago hispida Sieber ex Choisy
Selago hispida Sieber ex Choisy can be propagated by stem cuttings, division, and seeds.
Propagation by stem cuttings:
Stem cuttings should be taken in the spring or summer from the current season's growth. Cut a piece of stem about 3-4 inches long with a sharp, clean knife or scissors. Remove the lower leaves and any flowers. Dip the cut end in rooting hormone, and plant it in sterile soil mix. Keep the soil moist, but not waterlogged. After a few weeks, roots will start to grow, and new growth will appear. Once the roots are well-established, transplant the new plant into a larger pot or outdoor location.
Propagation by division:
Selago hispida Sieber ex Choisy can also be propagated by division. This method is best done in the springtime. Gently dig up the plant and separate the clump into smaller sections with a clean, sharp knife. Each section should have a healthy root system. Replant the sections in a well-draining soil mix, and keep moist until new growth appears.
Propagation by seeds:
Seeds of Selago hispida Sieber ex Choisy can be collected and sown in the early spring. The seeds should be sown in a well-draining soil mix, and covered with a thin layer of soil. Keep the soil moist and in a warm location. Germination should occur in a few weeks. Once the seedlings are large enough to handle, they should be transplanted into individual pots, and then hardened off before planting outside.
Disease and Pest Management for Selago hispida Sieber ex Choisy
Selago hispida Sieber ex Choisy, commonly called hairy swamp-heath, is a small shrub that is native to Australia. While it is generally a hardy plant, there are several diseases and pests that can affect it:
