Growing Basil Plant Care

Basil thrives in well-draining soil enriched with organic matter. Adding compost to your garden soil or potting mix enhances its nutritional content and promotes better drainage. Remember, basil likes its soil moist but not waterlogged.


Plants need moderate watering. If the top inch of the soil is dry, it’s time to water your basil plant again. Overwatering can lead to root rot, so letting the soil dry out between watering sessions is essential.


Basil plants need about six to eight hours of sunlight each day, indoors or in a garden bed. Ensure they are placed in a sunny spot to soak in ample daylight.

Humidity & Temperature

Basil loves warm conditions, ideally between 60 to 75°F. As an annual plant sensitive to frost, indoor basil plants should be kept away from chilly drafts. Basil plants need a moderate humidity level, making them suitable for most homes without additional humidity control.


Benefits from regular feeding with a balanced plant food with an NPK ratio of 10-10-10. Apply this every four weeks during the growing season to support optimal growth. Organic options, like compost or worm castings, can also be effectively used.

Propagation Techniques

Basil can be propagated from seeds or cuttings. Plant basil seeds indoors six weeks before the last spring frost for seed propagation. Once the seedlings are 2-3 inches tall and have a set of true leaves, they can be transplanted outdoors or to a larger pot indoors.

For propagation through cuttings, choose a healthy stem, and cut it just below a leaf node. Remove the leaves from the bottom part of the stem and place them in a glass of water. Within a week or two, you will see new roots sprouting. The rooted cutting can then be transplanted into a pot or garden bed.

Diseases & Pests

Basil can be susceptible to diseases such as fusarium wilt and downy mildew. Pests such as aphids, Japanese beetles, and whiteflies can also infest basil plants.

Regular inspection and organic pest control measures can help keep these issues at bay. Remember, maintaining good air circulation and watering at the soil level can prevent many diseases.

Harvesting Your Basil

Harvesting basil is an exciting step, allowing you to savor the fresh basil flavor in your dishes finally. The right time to harvest basil is just when the plant is about 6 to 8 inches tall. You can start by plucking a few leaves from the top to stimulate bushier growth.

Generally, it’s best to harvest your basil regularly throughout the growing season. This practice encourages the plant to grow more leaves and prevents it from going to seed, extending its lifespan. Ideally, it would help if you aimed to prune or harvest one or two basil plants at a time.

When harvesting, take your fingers and pinch the stem just above a leaf set. This encourages the plant to produce two branches from where you pinched it, resulting in a fuller plant over time.

For a significant harvest, wait until just before the plant starts to flower. At this stage, the leaves will have the highest concentration of oils, providing maximum flavor. If you notice a flower bud, pinch it off right away. Flowering changes the taste of the basil leaves, making them bitter.

Once you’ve collected the basil leaves, rinse them under cool water. You can use them immediately or store them for later use. Fresh basil leaves can be stored in a glass of water or wrapped in a damp paper towel inside a plastic bag in the refrigerator. For more extended storage, you can dry or freeze the basil leaves.
