Watering Needs
The Thelypodium lilacinum Greene var. subumbellatum Payson plant needs consistent watering to thrive throughout the year. This is particularly important during the summer months when the climate is hot and dry. Water the plants regularly and deeply, but do not overwater to avoid soil waterlogging and root rot problems. Always check the soil moisture level before watering to ensure that it is not too dry or too wet.
Fertilization
Fertilizing the Thelypodium lilacinum Greene var. subumbellatum Payson plant is essential to support the plant's growth and development. Use a balanced fertilizer that is rich in nitrogen, phosphorus, and other essential minerals. Apply the fertilizer during the growing season, following the manufacturer's instructions.

Pruning
Pruning the Thelypodium lilacinum Greene var. subumbellatum Payson plant is done to remove any dead or diseased branches, promote proper growth, and improve the overall appearance of the plant. Pruning should be done in the spring by cutting back the previous year's growth to about 6-12 inches from the ground. This encourages new growth and helps the plant to maintain its shape and size. Additional shaping and maintenance pruning can be done throughout the growing season, as needed.
