Petunia 'Supertunia Royal Velvet' problems — and how to fix them
Petunia 'Supertunia Royal Velvet' (Petunia × atkinsiana 'Supertunia Royal Velvet') 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.
Yellowing, hungry foliage
As a heavy feeder it pales and stops blooming if underfed; iron chlorosis (yellowing between veins) is common in cool, wet, or high-pH conditions. Feed regularly and correct iron and pH as needed.
Drying out fast
Vigorous trailing growth dries baskets and pots quickly in heat, causing wilt. Water consistently, sometimes twice daily, in moisture-retentive compost.
Botrytis / grey mould
Wet, humid spells rot spent flowers despite its self-cleaning habit. Improve airflow, remove mushy blooms, and water at soil level.
Budworm and aphids
Tobacco budworm caterpillars bore into buds and aphids infest soft new growth. Monitor regularly and treat with insecticidal soap or appropriate controls.
