rhubarb

Rhubarb (Rheum hybridum 'Starkrimson') prefers moist soil but should not be over watered. It is best to water when the top few inches of the soil are dry. Water rhubarb deeply and thoroughly about once a week. During warmer temperatures, it may require a bit more frequent watering, but unless your plant is displaying signs of wilt or extreme heat stress, weekly watering should be adequate.

Rhubarb (Rheum hybridum ‘Starkrimson’) requires at least 4-6 hours of direct sunlight every day to grow properly. Varieties of rhubarb can tolerate partial shade, but they usually perform best in full sun. Rhubarb prefers the cooler temperatures of spring and fall, allowing the plant to harden off and prepare for winter. While rhubarb will survive winter temperatures, direct sunlight during the cold winter months can lead to stunted growth in the spring.

Rhubarb (Rheum hybridum 'Starkrimson') should be pruned back to its crown in early spring, just before the new growth begins. After pruning, remove any dead or damaged leaves and any stems that are more than 2 years old. This will help keep the plant healthy and vigorous. To increase yield and promote healthy growth it can be pruned once or twice more during the growing season. During the summer, the tops of the stems can be cut back, leaving about 2 feet of height to help limit the spread of the plant and keep it from getting too large. At the end of the season, cut any remaining stems down to the crown for winter protection.
