watering

Rattlesnake master should be watered deeply when the surface of the soil has begun to dry. Aim for once a week in the Spring and Summer when temperatures are high, and twice a month in the Fall and Winter when temperatures are cooler. If planted in a container, ensure the soil is continuously moist but not soggy.

sunlight

Rattlesnake master needs full sun for optimal growth. It should receive at least 6 hours of sunlight each day. It is best planted in areas that have afternoon shade to protect it from the hot summer sun. However, it is drought tolerant and can tolerate short periods of direct sunlight if the temperature is not too high. To keep the foliage looking its best, water regularly during dry periods.

pruning

When to Prune: Rattlesnake master should be pruned in late winter or early spring, before the new growth begins to appear. How Much to Prune: Moderation is critical when pruning Rattlesnake master. Too much pruning can damage the plant, so it is important to only prune back the top growth, leaving enough to keep the plant shapely and healthy. Prune the plant back by about 1-third of its original height. Flowering stems can still be left in place.
