Pinch Out Shoot Tips

Provide slug protection as young growth appears. When stems are 12 inches high, pinch out the top bud to encourage bushiness and lots of flowers.

Frost Protection

As soon as the first light frost has blackened the leaves, cut off the foliage and dig up the tubers. Place them somewhere airy and frost free, so the stems can dry out fully.

Storing

When dry, brush the soil off the tubers, label them clearly and plant them in wooden boxes or large pots of dry potting mix. Keep them in a cool, dry, frost-free place until you can plant them out again the following spring.
