Troubleshooting
Indian Summer Raspberry problems — and how to fix them
Indian Summer Raspberry (Rubus idaeus 'Indian Summer') 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.
Confused pruning
As an everbearing type, it can be pruned for one large autumn crop (cut all canes to the ground in winter) or two crops (leave fruited summer canes). Mismatched pruning loses a harvest.
Suckering spread
Sends up suckers well beyond the original row. Install a root barrier or dig out wandering shoots each season to keep it in bounds.
Grey mould (Botrytis) on fruit
Rots ripe berries in wet, crowded conditions. Thin canes for airflow, harvest promptly, and remove mouldy fruit.
Cane diseases and iron chlorosis
Cane spot and spur blight strike weak, congested plants, while alkaline soil yellows leaves. Improve drainage, keep soil acidic, and remove old fruited canes.
