How to Grow Sweet Broom Shrub

Plant the sweet broom shrub in well-aerated soil with proper drainage. Add more organic matter like peat moss if necessary to create a rich soil that holds moisture without being soggy.

Give the shrub at least eight hours of sunlight and space to grow. It will reach heights between 5 and 8 feet and widths between 5 and 10 feet, so keep neighboring plants away that might crowd it later.

Prune off the spent flower stalks using a clean pair of pruning shears to keep the bush from becoming straggly. The evergreen leaves will accent your garden throughout the year. Remove any dead or broken parts of the plant.

Water the sweet broom once a month in the absence of rain. Generally, most growing areas will have more than enough rainfall to meet the watering requirements of a sweet broom plant.

Fertilize the sweet broom with a balanced fertilizer in the spring before the blossoms open if you notice the plant is not growing as rapidly as it should or if you have poor soil. Cover the bare soil around the plant with 2 to 4 inches of any organic material to help conserve moisture and enrich the soil.
