Frequently asked questions

How often should I water Italian Basil?

Keep the root zone evenly moist but well-drained. Water when the upper layer of soil or potting mix begins to dry; do not leave the roots sitting in water. In practice, water check container plants often in warm, sunny weather and water when the top 2–3 cm of mix feels dry. In garden beds, water during dry spells when the surface begins to dry. Feel the top 2–3 cm of soil or potting mix. If it is dry, water at the base until the root zone is moist and excess drains away. Water more often during hot, bright weather and less during cool or rainy spells. Italian basil is frost-tender; bring pots indoors before cold weather rather than trying to overwinter it outdoors.
