How to Care for the Plant
Water
For this reason, it's a good idea to add a thick mulch around the base of the plant once it has established. This will help it to retain moisture, even when it only receives infrequent watering. Mulching will also help protect your Sweet Pea Shrub as the winter temperatures arrive.
Pruning
Because this shrub can become rather leggy, pruning in early spring will help to ensure it keeps a compact and tidy shape. It will prevent too much bare trunk and sparsely blooming lower stems from developing and encourage abundant flowering.
Fertilizer
Using a slow-release fertilizer in the spring can encourage strong blooming.
