Basil Care Guide

Ocimum basilicum

Also known as: Sweet Basil, Thai Basil

Watering

Summer

Every 3 days

Winter

Every 5 days

Keep soil evenly moist but never waterlogged. These plants hate drying out completely.

Light

Direct sunlight

South-facing window, full sun for 4+ hours

Humidity

40-60%

Average home humidity is fine.

Pet & Child Safety

Safe for pets and children

Pot & Soil

Needs a pot with drainage. Standard potting mix. Keep warm - dies below 10°C.

Pot-size watering

The 3-5 day range is a starting point. A 5cm pot can need checking much sooner, while a 22cm pot may stay moist for longer. Keep the soil lightly moist, but check below the surface so a large pot is not staying soggy.

Balanced root room

This plant does best with a pot just larger than the root ball. Too much spare wet soil can make watering harder to judge.

Soil refresh

Refresh tired or compacted soil yearly, because moisture-loving plants still need air around the roots, not dense wet mix.

💡

Good to Know

Very thirsty herb. Pinch flower buds to keep producing leaves. Short-lived annual.
