Petunia 'Tidal Wave Silver' problems — and how to fix them
Petunia 'Tidal Wave Silver' (Petunia × atkinsiana 'Tidal Wave Silver') 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.
Outgrowing its space
Its aggressive vigour can overwhelm smaller bedding neighbours. Plant at the recommended spacing for the effect you want, and allow plenty of room in beds and large containers.
Wilting in containers
The large plant's water demand is high; pots and baskets can dry out and collapse quickly in heat. Water consistently, often daily, and use ample container volume.
Botrytis in prolonged wet
Although unusually Botrytis-tolerant for a petunia, sustained rain and humidity can still rot spent flowers. Maintain airflow and remove damaged growth.
Budworm and aphids
Tobacco/petunia budworm caterpillars damage buds and aphids cluster on new growth. Inspect regularly and treat with insecticidal soap or suitable controls.
