Because every shrub has different care needs, you’ll need to check with your local nursery for exact watering and feeding needs. For all plants, though, consider installing a drip irrigation system or watering basins to encourage direct watering to the roots. Adding mulches will help retain moisture and discourage weeds.

Flowering plants usually benefit from an annual application of fertilizer. However, if a plant looks weak and leaf color is pale, fertilizing is called for. Apply a complete fertilizer.

Pests and diseases may also be a concern, although most plants used for hedges are fairly resistant. If you notice the start of a problem, use non-toxic solutions, such as increasing watering and fertilizing, keeping the garden clean, and using insecticidal soaps and biological controls. If you take care of the problem when it first starts, it will usually not increase.
