The plant is also tolerant of dry soils but performs best in moist, well-drained soils. It is important to avoid waterlogged soil as it can cause root rot.
Cultivation Methods
Thalictrum fendleri Engelm. ex Gray var. platycarpum Trel. is a perennial plant that is native to North America. It can grow up to four feet tall and produces beautiful clusters of purple flowers. To cultivate this plant, choose a spot in your garden with well-draining soil and partial shade. Full sun can cause the plant to dry out, so it’s best to give it some shade during the hottest parts of the day.
When planting, dig a hole that is about as deep as the root ball and twice as wide. Gently place the plant in the hole and backfill with soil. Water thoroughly, but don’t overwater, as this plant prefers slightly dry conditions.
Watering Needs
The Thalictrum fendleri Engelm. ex Gray var. platycarpum Trel. plant prefers slightly dry conditions, so it doesn’t require frequent watering. However, it’s important to keep the soil moist in the first few weeks after planting to help the plant establish its roots. Once established, water the plant deeply once a week or when the top inch of soil feels dry to the touch. Avoid getting water on the leaves, as this can cause fungus and other diseases to develop.
Fertilization
Thalictrum fendleri Engelm. ex Gray var. platycarpum Trel. is not a heavy feeder and does not require frequent fertilization. However, you can give it a boost of nutrients with a balanced fertilizer once or twice a year. Apply in early spring and again in mid-summer, following the manufacturer’s instructions for application rates.
Pruning
Pruning is not necessary for Thalictrum fendleri Engelm. ex Gray var. platycarpum Trel. However, removing spent flowers can encourage the plant to produce more blooms throughout the growing season. Simply pinch or cut off the dead flowers when they start to fade. At the end of the growing season, cut back the plant to a height of a few inches above ground level to prepare it for winter.
Propagation of Thalictrum fendleri Engelm. ex Gray var. platycarpum Trel.
Thalictrum fendleri Engelm. ex Gray var. platycarpum Trel. can be propagated by both vegetative and seed methods.
Vegetative Propagation
The plant can be propagated vegetatively by root division. It is best to divide the roots during the winter dormant season. Carefully dig up the plant and shake off the soil. Separate the roots into smaller sections, each with several buds and roots, using a sharp, sterilized knife. Replant the divisions in the desired location at the same depth as the original plant.
Seed Propagation
Seed propagation is another method of propagating Thalictrum fendleri Engelm. ex Gray var. platycarpum Trel. Seeds can be sown directly in the garden in the fall or spring, or indoors in early spring. The seeds need to be stratified before sowing to mimic the natural winter cold period. To stratify, place the seeds in a plastic bag with a moistened paper towel and refrigerate for 6-8 weeks. After stratification, sow the seeds in a prepared bed or container. Cover the seeds lightly with soil, and keep moist until germination. Seedlings can be transplanted to the garden after the last frost.

For damping off, it's essential to keep your soil well-draining and avoid over-watering the plant. You can also use fungicidal sprays or soil treatments to control the disease. For leaf spot, remove any infected leaves and maintain proper sanitation by disposing of the fallen leaves. You can also use copper-based fungicides to control the disease.
Common Pests
Thalictrum fendleri is also prone to several pests, including aphids, spider mites, and thrips. Aphids are small insects that feed on the sap of the plant, causing it to wilt and turn yellow.
