Fertilization
It is recommended to fertilize Saxifraga arguta during the growing season. Fertilization should be done using a slow-release fertilizer applied according to the manufacturer's instructions. Over-fertilizing can lead to excessive growth, which can make the plant susceptible to diseases.
Pruning
Saxifraga arguta requires minimal pruning. Deadheading regularly helps to promote new blooming. If the plant becomes too leggy, it can be trimmed back by up to a third of its height in the spring. It is advisable to prune the plant after flowering to avoid cutting off the buds that will bloom the following year.
Propagation of Saxifraga arguta auct. non D. Don
Saxifraga arguta auct. non D. Don, commonly known as silver saxifrage, is a low-growing perennial plant that is semi-evergreen in nature. It produces delicate white flowers on long stems in the early spring and is often found in rock gardens, crevices, and on stony banks. Propagation of this plant is possible in several ways, including:
1. Seed propagation
Propagation by seed is a common method used for saxifraga arguta. The plant produces capsules that contain numerous tiny seeds which can be collected and sown in spring. The small seeds must be sown on the surface of a moist seed compost mixture in trays or pots. Cover the seed container with a plastic sheet to maintain moisture and place it in a bright location, at a temperature of around 15-20°C. It will take around three to four months for the seeds to germinate, after which they can be transplanted to individual pots.
2. Division
Division is another propagation method that is effective for saxifraga arguta. The plant should be lifted in early spring or autumn, and the root ball should be carefully shaken to remove the soil. Then, using a clean knife or shears, separate the plant into two or more sections, ensuring that each section has roots and shoots. Replant the divided sections in well-drained soil and water them regularly.
3. Vegetative propagation
Vegetative propagation can also be done using stem cuttings. Softwood cuttings are best taken in early summer when the plant is actively growing. Using a sharp knife, cut a stem about 10 cm long and remove the lower leaves. Dip the cut end of the stem into rooting hormone powder, place it in a pot or tray containing a suitable rooting compost, and firm the compost gently. Keep the cutting well-watered and in a warm, bright location, away from direct sunlight. Roots should form in about three to four weeks and after that, the young plant can be transplanted to a larger pot or in the garden bed.
Propagation of Saxifraga arguta auct. non D. Don is relatively easy and can be done successfully using one of the methods explained above. With proper care and attention, propagation can ensure that this beautiful plant can be shared and enjoyed for years to come.
