Choose a sunny, well-drained position. Moderately poor soil encourages less leaf and better flowers. Feed with Yates Thrive Soluble Flower & Fruit fortnightly for stronger plants. Protect from snails and slugs with Yates Blitzem.
Nasturtiums have natural insecticidal properties. They repel borers, codling moth, white fly, aphids and white cabbage butterfly. Remove spent blooms to promote flowering.
