Rheum rhabarbarum
Rhubarb (Rheum rhabarbarum) is a versatile and hardy perennial plant. It has long, thick stalks with large, bright-green leaves that are edible when cooked. The stalks can be harvested in spring and early summer when they are sweet and juicy. The stalks can be used for pies, jams, tarts, sauces and savory dishes. They can also be used to make drinks and jams. Rhubarb is low in calories and high in fiber and vitamin C, making it a nutritious addition to any diet.

watering
Rhubarb plants should be watered deeply and infrequently. In spring, when the leaves are just starting to grow, provide about an inch of water per week. As the plant matures and leaves become fuller and stems thicken, water sparingly, just enough to prevent the soil from drying out completely. When the leaves begin to yellow and die back in late summer/early fall, stop watering. Rhubarb will go dormant until the following spring.
sunlight
Rhubarb requires daily access to sunlight for optimal growth and production. It should ideally receive 6-8 hours of direct sunlight per day, which can be in the form of either direct sunlight or bright indirect light indoors. While rhubarb can tolerate some shade, the growth and harvest will likely be reduced when not given the proper amount of sunlight.
pruning
Rhubarb should be pruned in spring, after new growth has begun. Remove all of the dead leaves and any shoots that are more than 2 years old. Cut these shoots to the ground level. Cut back any shoots that are longer than 24 inches to 16-20 inches in length. This will encourage healthy, new growth. Prune a third of the rhubarb crown each spring, every 2 to 3 years. This will help to ensure that your rhubarb stays fresh and fruitful.
