Snow-in-summer (Cerastium tomentosum) should be watered when soil is dry to the touch up to 1 inch below the surface. It is best to water deeply but less often, such as once or twice a week in summer and once every 10 days in the cooler months. When watering, make sure to soil is evenly moist, but never soggy or soaked in water.

Snow-in-summer (Cerastium tomentosum) needs partial to full sun exposure throughout the day, in order to thrive. It prefers 4-6 hours of direct sunlight each day, preferring more shade in the hottest part of the day, during the middle of summer. Early morning and late afternoon/early evening sun exposure this species enjoys the most as these hours typically provide increased humidity and protection from intense heat and sunlight. Snow-in-summer should not be planted in an area that has less than 4 hours of sunlight each day as this can lead to lower quality blooms and unable to compete with competing plants in the area.

Snow-in-summer (Cerastium tomentosum) should be pruned lightly in late winter (December to February) to remove any damaged or dead foliage, as well as remove any woody-looking stems to promote new growth. To promote dense, bushy growth, lightly prune the plant in late summer or early fall, cutting parts of the plant back down to almost ground level. This light pruning helps to promote blooming in the upcoming spring.
