Troubleshooting
Solanum crispum 'Glasnevin' problems — and how to fix them
Solanum crispum 'Glasnevin' (Solanum crispum 'Glasnevin') 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.
Frost damage
In cold winters or exposed sites stems can be killed back; grow against a warm, sheltered wall and mulch the base. Cut out damaged growth in late spring once regrowth shows.
Sparse flowering
Usually too little sun or excess nitrogen. Site in full sun and switch to a high-potash feed; over-feeding with nitrogen drives foliage at the expense of blooms.
Leggy, untidy growth
The lax stems sprawl if left unsupported. Tie in regularly and prune after flowering to keep it within bounds and encourage a denser framework.
Aphids
Soft new shoots attract aphids, which distort growth and leave sticky honeydew. Dislodge with water or treat early; encourage ladybirds and other predators.
