Propagation by division
Saxifraga serpyllifolia Pursh var. chrysantha (Gray) Dorn can also be propagated by division. This method is best done in the fall or early spring. Dig up the plant and separate it into sections, making sure each section has roots and several shoots. Replant the sections in well-draining soil and keep it moist until the plant becomes established.
Disease Management
One of the common diseases that might affect Saxifraga serpyllifolia Pursh var. chrysantha is root rot, which is caused by fungal pathogens. To manage this disease, it is essential to ensure proper drainage of the soil and avoid overwatering. In severe cases, the affected plant parts should be removed, and the plant treated with a fungicide just to be sure.
Another disease that might affect this plant is powdery mildew, which manifests as a white, powdery growth on the plant leaves. To manage this condition, the affected plant should be treated with a fungicide, and the leaves should be mulched or raked to decrease humidity. Additionally, the diseased plant parts should be removed and destroyed.
Pest Management
A common pest that might attack Saxifraga serpyllifolia Pursh var. chrysantha is the spider mite, which pierces the plant cells leading to yellow and distorted leaves. To control this pest, you can apply a miticide to the plant's foliage. Another pest is the aphid, which sucks sap from the plant leading to stunted growth. To manage this pest, the plant can be sprayed with insecticidal soap. Cutting-back of the plant can also help to get rid of the aphids.
Also, the plant can be affected by snails and slugs, which cause damage to both flowers and leaves. Handpicking of these pests is essential to keep them under control. Alternatively, barriers like copper tape can be used to keep them away from the plant.
