How To Grow Dark Opal Basil From Seed: Using seedling modules or small pots, sow a pinch of Dark Opal Basil seeds in each pot and lightly cover with compost. 

When the seedlings develop their first set of true leaves, transplant them into bigger pots or to their place in the garden, once the risk of frost has passed.

Harvest leaves as required, but make sure to pick above the bottom two true leaves, so the plant can re-grow. Don’t be shy about harvesting Basil, as this will help it to grow more vigorously.
