Growing Thai basil outside the house

Thai basil when outdoors thrives only if it gets enough sunlight and moist soil that is drained well but not soggy for too long.

Otherwise, you should stick to planting indoors until the last frost.

How to propagate Thai basil?

Thai basil can be propagated in three ways:

By seeds

For sowing the Thai basil seeds just press them deep about half an inch into the soil. Thai basil can be grown from seeds but the results sometimes don’t appear. Many gardeners sow multiple seeds due to this reason. The space between the Thai basil should be good enough which is about 10-12 inches so that seedlings get enough space, air, moisture, and sunlight.

The seedlings will appear in a week or 1 1/2 weeks. Then the lost frost can be transplanted.

By cuttings

Using the stem cutting of Thai basil plants is another way to easily propagate Thai basil plants. Use a sharp clean sterilized knife to cut the stem in the middle of about 3-4 inches and make sure the cutting has about 1-2 foliage including nodes. Insert the node in a jar of water and wait for a few days until you will see the tiny roots emerging from the cutting. Move the cutting into the soil with roots, soil on top of the roots, and let the plant grow.

Basil is an annual herb that will thrive if the conditions are warm and hot but during the scorching summers, little cold conditions provided to it is always a great idea. Make sure there is no risk of frost any more! The Thai basil reaches up to a height of 45cms and yields colored leaves
