Weigela Czechmark Twopink shrubs are not fussy and do not have specific water needs. It's best to make sure they stay evenly moist in well draining soil while the roots are still becoming established. After planting, give them a deep watering their first day. Then, check the soil each day to see how quickly or slowly the top two inches dry out. Once the top 2 or 3 inches are dry to the touch it is time to water again. When in doubt, it is OK to wait an extra day so that you do not run the risk of overwatering. For each gallon size of the container it arrived in, a 5 count of water from a typical garden hose will do (3 Gallon Pots get 15 seconds, etc).
