Frequently Asked Questions

What’s a common problem for Viola × wittrockiana (Swiss Giants) and how do I treat it?

Swiss Giants commonly suffer from gray mold (Botrytis) and foliar fungal spots, especially when flowers and leaves stay wet. Water at the soil line in the morning, space plants for airflow, and remove affected leaves or spent blooms right away. If disease spreads, use a labeled fungicide for ornamentals and follow the reapplication interval on the label.

How often should I water Swiss Giants during the main growing phase?

During the main growth period, keep the soil consistently moist but not soggy—aim for evenly damp soil to about 1 inch deep. Water when the top inch begins to dry out, then soak thoroughly; in warm spells this may be about 2–3 times per week, while cooler weather needs less. Avoid frequent light misting that leaves foliage wet, which increases fungal risk.

How can I tell when Swiss Giants are ready to harvest?

For Viola × wittrockiana grown for flowers, you can harvest when buds are fully formed and the petals show full color, usually around 70 days from planting. Pick flowers in the morning when blooms are most turgid, and continue harvesting regularly to encourage more flowering. If you’re harvesting for seed, wait until pods are dry and brown, then harvest before they shatter.
