rhubarb

Rhubarb (Rheum hybridum 'New Valentine') should be watered 1-2 times a week during active growing season. During early spring when the plant is beginning to grow, the soil should be kept moist at all times. In summer, water deeply every 1-2 weeks, allowing the water to penetrate deep into the soil. In autumn, water every 10-14 days to allow the rhubarb time to enter dormancy. During winter months, you should reduce watering and only water when the soil is completely dry.

Rhubarb (Rheum hybridum 'New Valentine') requires at least 6 hours of direct, full sunlight each day in order to grow healthy and strong. The plant grows best in cooler climates and can fail to thrive in areas that experience extreme heat. Rhubarb should receive the most sunlight possible in the early morning and should be protected from the heat of the afternoon sun. In order for the plant to produce fruit, it must experience periods of cooler temperatures and extended sunlight.

Rhubarb (Rheum hybridum 'New Valentine') should be pruned each year in the early spring, before the plant begins to produce new growth. Pruning should be done carefully as the rhubarb is a relatively shallow rooted plant. Remove any flower stalks that appear, as these take energy away from the plant and limit its potential in the garden. Cut back the long stem-like leaves at the base of the plant to about 10cm (4in) from the ground, ensuring that you leave enough foliage to enable the plant to photosynthesise and produce food for itself. When pruning, trim off any dead, weak or diseased stems, being careful to use a clean sharp blade and sterilise if necessary to prevent the spread of disease. For optimum growth, it is recommended that a healthy rhubarb plant is cut back between 1/3 to 1/2 of its growth.
