Planting Tips

Where to Plant

Phlox subulata ‘Snowflakes’ is best planted in areas with full sun to partial shade. It excels in rock gardens, slopes, and along borders, where its full flowering potential can be showcased.


This plant thrives in full sun but can also grow well in partial shade. Full sun exposure ensures the most abundant flowering and healthy growth.


Well-drained soil is key for Snowflake Creeping Phlox. It adapts to various soil types but prefers slightly acidic to neutral soil conditions.

Regular watering is crucial after planting until established. Once mature, Snowflake Creeping Phlox is relatively drought-tolerant but benefits from occasional watering during extended dry periods.


A light application of balanced fertilizer in early spring can encourage vigorous growth and flowering. Avoid over-fertilizing to prevent excessive foliage growth at the expense of blooms.


Prune after flowering to maintain shape and promote denser growth. This also helps prevent the center of the plant from dying out.
