Answer: Weigela will grow in full sun to part shade. They bloom in the late spring, and should be pruned back after blooming. Cut back the stems that have produced flowers, leaving those that have not yet blossomed. These are rugged plants, once established. If you planted your weigela last year, it required extra water to help establish itself in the garden. If the plant is several years old and just started needing additional water, perhaps there's a problem with the soil and/or the root system. If it doesn't thrive this year, dig it up and inspect the roots. If the roots cannot penetrate the soil, or if the soil is too sandy and drains too quickly, amend the soil with large amounts of organic matter and then replant your weigela. These are normally tough plants that are easy to establish.
