About

The King of Herbs

Basil has been cultivated for more than 4,000 years, originating in tropical Asia and making its way through ancient trade routes to the Mediterranean, where it became inseparable from Italian and Greek cuisines. Today dozens of cultivars exist - from classic Genovese to Thai, lemon, and purple varieties - each with a distinct aromatic profile.

Despite its delicate reputation, basil is a vigorous grower when given warmth and sunshine. It thrives in the same conditions as tomatoes, which is no coincidence - the two are celebrated companion plants, and pairing them in the garden is as logical as pairing them on a plate.

How to grow

Planting & care

Start seeds indoors 6 weeks before your last frost date, or direct-sow once soil reaches 60 F. Basil hates cold: even a light frost will blacken leaves overnight. Space plants 12-18 in apart in rich, well-draining soil amended with compost. Full sun - at least 6-8 hours daily - is non-negotiable for vigorous, flavorful growth.

Water deeply at the base rather than overhead to prevent fungal issues, keeping soil consistently moist but never waterlogged. Pinch flower buds the moment they appear to redirect energy into leaf production and delay bitterness. Fertilize lightly with a balanced organic fertilizer once a month; too much nitrogen boosts leaves but dulls flavor.

Good to know

Pinch Early, Pinch Often

The single best thing you can do for your basil plant is pinch it back regularly. Nipping the growing tip just above a pair of leaves encourages two new side shoots to form, quickly turning one leggy stem into a full, bushy plant that produces far more harvestable foliage all season long.
