Wild Lupine problems — and how to fix them
Wild Lupine (Lupinus perennis) 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.
Resents transplanting
Its deep taproot makes potted plants tricky to move and slow to establish. Sow direct or plant out young seedlings, and disturb the roots as little as possible.
Needs lean, sandy soil
It declines in rich, heavy or wet ground and is genuinely hard to keep in conventional fertile borders. Give it poor, sharply drained sandy soil in full sun.
Powdery mildew
Greyish leaf coating, worse in humidity, shade or crowding. Site in open sun with airflow and cut affected foliage back to clean basal growth.
Aphids
Lupin aphid and other species cluster on stems and spikes and can distort flowers. Dislodge with water and encourage natural predators rather than spraying.
