Troubleshooting
Spanish Draba problems — and how to fix them
Spanish Draba (Draba hispanica) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot
The most common cause of death. Caused by waterlogged soil or water pooling at the rosette in winter. Ensure sharp drainage and apply a grit collar around the crown. Avoid overhead watering in cool, wet seasons.
Aphid infestation
Clusters of grey or green aphids can colonise young spring growth and flower stems. Treat with a strong water jet or insecticidal soap; avoid systemic insecticides near pollinators visiting the flowers.
Loss of compact habit
Plants grown in rich soil or shade become loose and sprawling, losing their characteristic cushion form. Replant in pure scree mix in a sunnier position; renovation by division can restore vigour.
