red-veined pie plant

The red-veined pie plant (Rheum australe) grows best when watered consistently with a schedule of once or twice a week, depending on the season. In the growing season (spring-summer) it’s best to water every week to keep the soil moist but not overly soggy. In the fall and winter, water less frequently when you notice the soil is dry, usually every 2 weeks. When watering, give the plant a thorough soaking so that the water reaches all the way down to the roots. Make sure to drain any excess water and avoid waterlogging; let the soil partially dry out between waterings to help protect against fungus and rot.

Red-veined pie plant (Rheum australe) prefers full sunlight in spring and early summer. During this time, it should receive at least 6 to 8 hours of direct sunlight each day. As the summer progresses and into the fall, the sunlight should be reduced to 4 to 6 hours daily to avoid scorching of leaves. In winter, the plant should receive at least 2 to 4 hours of indirect, bright light each day.

Red-veined pie plant (Rheum australe) should be pruned in late winter or early spring, just before new growth begins. Pruning should take place when the plant is dormant, and all dead, damaged, or diseased branches should be removed. Older branches may also be thinned to encourage air flow and help reduce mildew growth. Pruning should be done to shape the plant, removing any crossing branches, to make sure it has a nice, open habit. Any branches growing outward, rather than upward should be pruned to promote a stronger main stem. Generally, only about 1/3 of the top growth should be removed to keep the plant in balance.
