Tomato, Sage, Garlic, Onion, Onions, Chives, Rosemary, Mint and Nasturtium.
Single Plants: 30cm (11") each way (minimum)

Sow and Plant
Sow indoors in spring and set out when plants have 5 leaves. Start another planting indoors in midsummer, and set out in early fall.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
The flavor of collards is improved by cool temperatures, so fall is the preferred time to grow this crop.
Harvest leaves individually, when they are about the size of your hand.
In warm weather, caterpillars may feed on leaves. Exclude them with floating row covers. In cool weather, watch for outbreaks of gray-green cabbage aphids in leaf crevices. Pick off and compost badly infested leaves.
