Planting, Growing, and Harvesting Basil
Planting
Basil will grow best in a location that gets 6 to 8 hours of full sun daily, though it can perform well in partial sun, too.
Soil should be moderately fertile and moist but well-draining. Basil works great in containers or raised beds, as these allow for better drainage. The pH of the soil should ideally be in the range of 6.0 to 7.5 (slightly acidic to neutral).
If you plan on cooking with these plants, plant in clean soil, don’t use insecticides, and grow them away from driveways and busy streets so exhaust won’t settle on the plants.
When to Plant Basil
- To get a jump on the season, start the seeds indoors 6 to 8 weeks before transplanting outside. (See local frost dates.)
- To plant outside, wait until the soil has warmed to at least 50°F (10°C)—preferably around 70ºF (21°C) for best growth. Nighttime temperatures shouldn’t drop below 50°F (10°C).
- Don’t rush basil. Without heat, the plant won’t grow well!
How to Plant Basil
- If you are sowing seeds directly into the ground, sow no more than 1/4-inch deep. Seeds should germinate within 5 to 7 days. Once they have developed 2 to 3 pairs of true leaves, transplant them.
- If you are planting the germinated seedlings or starter plants in the ground, spaced 10 to 12 inches apart; basil should grow to about 12 to 24 inches in height.
- A 2- to 3-inch mulch of compost or ground-up leaves retains soil moisture and minimizes weeds around the plants.
- Tomatoes make great neighbors for basil plants in the garden—and on the plate—so many gardeners will plant the two warm-weather friends around the same time.
Growing
How to Grow Basil
- Make sure that the soil is moist. Basil plants like moisture.
- If you live in a hot area, use mulch around the plants (the mulch will help hold in moisture and suppress weeds).
- During the dry periods in summer, water the plants freely.
- After the seedlings have produced their first six leaves, prune above the second set. This encourages the plants to start branching, resulting in more leaves for harvest.
- Every time a branch has six to eight leaves, repeat pruning the branches back to their first set of leaves.
- Fertilize sparingly throughout the season with a 5-10-5 fertilizer.
- After about 6 weeks, pinch off the center shoot to prevent early flowering. If flowers do grow, just cut them off.
- If the weather is going to be cold or if a sudden frost is imminent, be sure to harvest your basil beforehand, as the cold temperatures will destroy your plants.

- Purple basil adds some nice color to your garden (when steeped in white vinegar, it creates a beautiful color)
- Thai basil adds a sweet licorice flavor to a dish.
Cooking Notes

Brown spots on basil can indicate a variety of issues. Avoid watering basil leaves from overhead; only water at the soil level and don’t let water or soil splash on leaves.
Hi, I planted some seeds several weeks ago. They have sprouted quickly, but are not producing their first set of true leaves. It has been at least 3 weeks since they sprouted. Any advice? Do they need fertilizer?
Initial basil growth can be slow, but to help yours along as much as possible, make sure that they’re getting enough light (full sun, 6–8 hours a day), enough water, and that temperatures aren’t dropping below 50°F. If those factors are under control, you may add just a bit of a 10-10-10 fertilizer, following instructions on the packaging.
Does anyone know which basil is used in pizza? I have grown different basil over the years trying to find that flavor. Years ago we bought some basil leaf spice from the store it made the food taste like eating pizza, the store stopped making it. At first we bought basil spices from different companies not one them have the pizza taste.
Yum. Basil and pizza. A lot of readers use a Spicy Globe variety of basil, but others prefer a Sweet Basil. It has the flavor most associated with Italian cooking, similar to ‘Genovese’ or ‘Classico’ used on Margherita pizzas in Italy.

Hi there. I'm in Southwestern Michigan. I'm thinking of starting my first garden in the Spring.
The previous owners of this house had a dog that pooped in an area in my bag yard. It's been two years since the dog owners lived here. So, would it now be safe to use that area for part of my garden? Or would it not be a good idea since some bacteria or whatever from the dog poop might still be there? Also, what kind of cover plants could I use to prepare the ground for Spring garden planting?
Got some knowledge of the plant, it's use, planting and how to take care. Thanks.
I have gotten some knowledge of the plant and still haven't found an answer to my questions. But thanks for your input anyway.
will basil plants survive winter and grow the following year ?
Basil is one of those herbs that won’t make it through the winter. It likes warm temperatures and heat.
Some people try growing basil in pots indoors, but that is challenging, too, because basil likes indoor temperatures in the 70s day and night.
It’s best to harvest the basil and freeze it for year-round use! See our article on preserving herbs.
