Watering
Newly planted shrubs should be watered three times a week for four weeks after planting. Most shrubs require 2 gallons of water a week. After the initial four weeks of watering, monitor the shrubs and makes sure they are recieving the equivilant of 1 inch of rainfall. If rain occurs hold off on watering to prevent over watering. Water all shrubs, new and established, during times of drought. Larger shrubs will require more water, upwards of 15 gallons depending on the size.
Pruning
The best time to prune bloomingt shrubs is after they bloom. This is usally late spring or early summer. If a shrub blooms later in the year then late winter or early spring pruning is suggested. All other shrubs such as evergreen shrubs and non-flowering deciduous shrubs can be pruned in the winter or any other time of the year when pruning is desired.
