Supertunia 'Vista Bubblegum' problems — and how to fix them
Supertunia 'Vista Bubblegum' (Petunia 'Vista Bubblegum') 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.
Nutrient deficiency / yellowing
Pale lower leaves and weak bloom signal hunger or iron chlorosis; this vigorous cultivar needs consistent feeding to look its best.
Outgrowing companions
Its fast spread can smother smaller plants in mixed containers; pair with equally vigorous partners or give it a pot of its own.
Botrytis / grey mould
Cool, wet, crowded conditions rot flowers and stems; improve airflow, water at the base, and clear spent blooms.
Budworm damage
Caterpillars chew buds and petals and halt flowering; handpick or apply Bt.
