Soil Requirements
The slender mountain saxifrage grows well in well-draining soils that are rich in humus. It prefers soils that are moderately moist, and it can tolerate short periods of drought. The plant can also grow in rocky or gravelly soils, as long as there is enough moisture and nutrients to support growth. pH levels of the soil should range between 5.0 to 6.5 for the best growth results.
Overall, if provided with the appropriate growth conditions, Saxifraga gracillima A.M. Johnson will thrive and add beauty to its surrounding environment.
Cultivation Methods
The Saxifraga gracillima A.M. Johnson thrives best in well-draining soil that is rich in organic matter. It can be grown as a container plant or in a rock garden. The plant requires about 4-6 hours of sunlight each day and can tolerate partial shade.
Watering Needs
The plant prefers to be kept consistently moist, but not waterlogged. It is important to keep the soil moist at all times, especially during hot/dry weather. Increase the watering frequency if the plant is in a container, as they tend to dry out quickly.
Fertilization
Use a balanced liquid fertilizer once every two weeks during the growing season, from spring through early fall. Avoid fertilizing during the winter months when the plant is dormant. Over-fertilization can cause damage to the roots, so always follow the instructions on the product packaging.
Pruning
Deadheading spent flowers from the saxifraga gracillima promotes further blooming and helps to maintain the plant's appearance. If the plant begins to get too leggy, you can pinch or cut back the stems to encourage bushier growth. It is advisable to prune during the springtime when the plant is actively growing.

Stem Cutting Propagation
Stem cutting propagation is another propagation method for Saxifraga gracillima A.M. Johnson. This method is usually done during the summer months. Take a healthy stem cutting of about 6 inches in length and remove the lower leaves. Dip the end of the cutting in rooting hormone powder and plant it in a well-draining potting mix. Water the soil gently, and place the pot in a shaded and humid spot. The cutting should produce roots in about 3-4 weeks.
Overall, Saxifraga gracillima A.M. Johnson is an easy plant to propagate by seed, division, and stem cuttings. With proper care and attention, you can produce many new plants from a single specimen.
Disease and Pest Management for Saxifraga Gracillima A.M. Johnson
Saxifraga Gracillima A.M. Johnson is a beautiful flowering plant that is relatively resistant to pests and diseases.
