Sister Rosie™ Scotch Broom

Where to Plant

• Sunlight: Full sun is essential for Sister Rosie™ Scotch Broom. Ensure it receives at least 6 to 8 hours of direct sunlight daily to maintain the intense pink flower color and a dense, upright habit.
• Soil: This plant thrives in poor, lean soils that drain quickly. If you have heavy clay, plant it in a raised bed or a mound to prevent root rot, as it actually prefers sandy or rocky conditions over rich, loamy garden beds.

Watering Requirements

During the first growing season, water deeply once or twice a week to help the roots reach deep into the soil. Once established, Sister Rosie™ is exceptionally drought tolerant and rarely needs supplemental water unless there is a prolonged dry spell. Overwatering or inconsistent moisture can lead to root stress and a decline in the plant's overall vigor.

Pruning Tips

This shrub blooms on "old wood," meaning the flower buds were formed during the previous summer. Prune immediately after the spring flowers fade by cutting back the green stems by about one third, but avoid cutting into the thick, woody base. Think of this like a light trim to keep the plant from becoming leggy and to encourage a fresh flush of growth for next year's blooms.

Fertilizer Needs

Use a balanced, slow-release fertilizer in early spring just as new growth appears. Avoid using high-nitrogen fertilizers late in the summer because they stimulate soft, leafy growth that won't have time to harden off before the first frost. This plant is naturally efficient at gathering nutrients, so a light touch is better than overfeeding.
