How to Grow and Care for Thai basil plants

How to Grow Thai basil plants

Thai basil plants Propagation with Seeds
Growing Thai basil plants from seeds is easy and cheap. Seeds are usually very cheap and easily available. Usually, Thai basil plants have relatively low germination rates from their seeds. However, that doesn't mean you can't successfully grow thai basil plants from seed. This means that you may need to do more work and add a few more resources to increase the likelihood of success.
To obtain seed
To avoid such problems, you should check the quality of Thai basil Plants seeds before buying. The best and easiest way is to choose the seed brand with the most online reviews.
Prepare the seed starting mixture by wetting it with warm water. Be careful how much water you put in, as the mixture does not strain too wet. Next comes your container. You can buy seed trays or reuse everyday items that you may already have at home, such as milk or juice cartons.
Any shallow container can be used, but be sure to leave enough drainage holes in it. Fill containers with a moist mixture around the edges and plant seeds on each container. Use four to five seeds per 1.5 x 1.5 inch container.
Grow Thai basil
When finished, cover the seeds with a quarter inch of soil and spray with water, then cover the container with plastic wrap.
Take care of the seed
Keep the seeds in a warm place away from strong and direct sunlight. Remove plastic wrap a few hours a day to let the seeds breathe. Meanwhile, spray the mixture with water to keep the humidity around the seeds as high as possible. After a week or two, your seeds will germinate, and then Thai basil plants can be transferred to different pots.
Thai basil plants Propagation with Stem Cuttings
Growing Thai basil plants from cuttings is more efficient and easier than growing them from seeds. The only downside here is that you need to have a fully fledged thai basil plant to get cuttings from it.
Knowing when to pick branches of Thai basil plants is a fairly simple decision. Wait until a Thai basil plant is at least four inches tall or has at least four sets of leaves on most of its branches. In this case, the cuttings you take will be enough to start taking root and become independent Thai basil plants.
Choose any stalk you want, but make sure it's healthy and strong. Count three or four sets of leaves -- starting at the top -- and make a cut directly under the last leaf.
Remove all the leaves at the bottom of the cut and leave two sets of leaves at the top.
After that, you should submerge the cut in a glass of water. Avoid direct sunlight and make sure to change the water every other day.
After two to three weeks, the cuttings will have developed a well-developed root system. At this point, it will be ready to move to the pot so that it can grow as a plant.

How to Care for Thai basil plants

Light Care

Light is perhaps the most controversial and complex issue when growing thai basil plants indoors. Even more challenging, mature Thai basil plants need long exposure to direct sunlight to bloom.

Soil Care

Thai basil plants prefer a moist but well-drained soil mixture. For best results, modify the potting soil with a little organic compost before planting Thai basil plants indoors. Also, make sure to choose a pot for your Thai basil plants that has plenty of drain holes at the bottom so the soil doesn't become wet or waterlogged.

Water Care

There is a big difference between watering Thai basil plants in pots and watering them in the garden, and this is where all mistakes can happen. Overwatering and watering are two very common problems when growing Thai basil plants. If the temperature is not very high, you cannot water Thai basil plants every day, whereas in hot weather you may need to water Thai basil plants twice a day. The best way to know when to water Thai basil plants is to simply monitor the soil every day.

Temperature Care

Because you grow Thai basil plants indoors, you need to be extra careful about fluctuating temperature and humidity levels around the plants. Daytime temperatures of around 75°F (24°C) are best for Thai basil plants. The temperature should drop to around 68°F (20°C) overnight.

Fertilizer Care

If you've previously modified your soil with organic compost, chances are your Thai basil plants don't need additional nutrients. However, if you notice that your plants are not growing much, you can feed your Thai basil plants once a month using weak liquid fertilizer.

Pruning Care

Harvest regularly to promote compact growth. An annual herb, plants should be cut down at the end of the growing season. The leaves can be dried for use throughout the year.

Decorative Uses for Thai Basil

The aroma of Thai basil and its distinctive purple stems/flowers make it an excellent choice for decorative purposes. Simply cut a flowering piece from the plant long enough to fit into a container of your choice. Remove all leaves below the waterline and place them in a container or a glass of water. If replaced with water and no leaves, the cuttings will last for weeks.
A bunch of basil can be lovely, but you can also mix up other flowers from your garden or even from the market. The high pointy point of the Thai basil flower makes it an excellent filler flower (say five times faster) that can add height and airy elements to a composition.
