Start Scotch broom seeds indoors in early spring, then transplant the seedlings to a sunny location outdoors after the last frost of the season. Scotch broom is typically propagated in late summer by taking a cutting and planting it outdoors.
Seedlings and cuttings require regular watering during the first season after planting. After the first growing season, water the plant only when soil is very dry, and avoid overwatering the plant. The Scotch broom is a drought-resistant plant that does not require regular watering after the root system is well-established.
Fertilize the plant at the beginning of spring, and prune the bush before seed pods form to prevent the Scotch broom from becoming invasive. To prune the Scotch broom plant, remove up to one-fourth of the flowering branches, and remove any dead or woody stalks.
