Rayed Broom problems — and how to fix them
Rayed Broom (Genista radiata) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Irreversible branch die-back from pruning
Cutting into bare, old wood on any Genista species results in dead branches, not regrowth. Restrict any trimming to green-stemmed shoots immediately after flowering and never attempt renovation pruning.
Poor establishment in wet or clay soils
On heavy or waterlogged soils the plant fails to establish and declines rapidly. Incorporate coarse grit when planting, raise the planting area, or grow in a gravel garden.
