Troubleshooting
Elderberry 'Nova' problems — and how to fix them
Elderberry 'Nova' (Sambucus canadensis 'Nova') 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.
Poor fruit set
Though listed as self-fertile, 'Nova' crops far more heavily with a different cultivar (e.g. 'York' or 'Adams') flowering nearby for cross-pollination.
Spider mites and aphids
Hot, dry spells bring aphids on new shoots and mites under leaves; rinse foliage and keep the root zone watered to reduce stress that invites infestation.
Drought stress
Shallow roots make it quick to wilt and drop fruit in dry summers. Mulch heavily and water deeply during flowering and berry fill.
Overgrown, unproductive canes
Without renewal pruning, old canes crowd the centre and reduce yield. Remove the oldest third of canes at the base each late winter.
