Harmonic Herb starts basil early with our tomatoes, around the equinox, and transplant sometime in June, after most risk of frost has passed. Sow seed 6 mm (1.4") deep, and seek a balance between two wet and too dry. Germination is enhanced by warmth, so we use heat mats to get them going in plug trays. They can take full sun - with enough water - but Fusarium infection Is a concern. Harvest the tops as they approach flowering - this pruning promotes branching and leaf production. We love making fresh pesto, and also like freezing basil in jars, pureed with olive oil and lemon juice for winter pesto.
