Basil is a leafy, fragrant annual with a bushy appearance. The most common type of basil is sweet basil; other types include purple basil (less sweet than common basil), Lemon basil (lemon flavor), and Thai basil (licorice flavor). Basil is easy to grow and works well in Italian dishes, but it only grows in the summer, so plan accordingly.

Planting

  • To get a head start, start the seeds indoors 6 weeks before the last spring frost.
  • Ensure your outdoor site gets 6 to 8 hours of full Sun daily; soil should be moist and well-drained.
  • After the last frost date, plant the seeds/seedlings in the ground about 1/4-inch deep. The soil should be around 70ºF for best growth.
  • Plant the seeds/seedlings about 10 to 12 inches apart. They should grow to about 12 to 24 inches in height. For smaller plants, plant farther apart (about 16 to 24 inches).
  • During the dry periods in summer, water the plants freely.
  • Remember to pinch out the flower heads as soon as they appear to make sure that the leaves will continue growing.
  • If you're planning on cooking with these plants, plant in clean soil (don't use fertilizers that leave harmful residues) and grow them away from driveways and busy streets so that exhaust won't settle on the plants.
  • Tomatoes make great neighbors for basil plants in the garden.

Care

  • Make sure that the soil is moist. Basil plants like moisture. If you live in a hot area, use mulch around the basil plants (the mulch will help keep the soil moist).
  • Make sure to pick the leaves regularly to encourage growth throughout the summer.
  • After 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, be sure to harvest your basil beforehand, as the cold weather will destroy your plants.

Pests

  • Aphids
  • Variety of bacterial and fungal leaf, stem, and root diseases

Harvest/Storage

  • After the seedlings have their first six leaves, prune to above the second set.
  • Every time a branch has six to eight leaves, repeat pruning the branches back to their first set of leaves.
  • The best time to harvest is right when the plant starts to bud (before the flowers bloom).
  • Basil is most pungent when it is fresh.
  • If pruned regularly, twelve basil plants will produce 4 to 6 cups of leaves per week.
  • The best method for storing basil is freezing. Freezing will prevent the plant from losing any of its flavor. To quick-freeze basil, dry whole sprigs of basil and package them in airtight plastic bags.
  • Another storage method is drying the basil (although some of the flavor will be lost). Pinch off the leaves at the stem and place them in a well-ventilated and shady area. After 3 to 4 days, if the plants are not completely dry, place them in the oven on the lowest heat setting with the door slightly open. Remember to turn the leaves (for equal drying) and check them frequently.

Recommended Varieties

  • Cinnamon basil, to add a hint of cinnamon to a dish
  • Purple basil, to add some nice color to your garden (when steeped in white vinegar, it creates a beautiful color)
  • Thai basil, to add a sweet licorice flavor to a dish.

Help my new basil seeds starting off great...too many starters what shall I do?

By Almanac Staff on May 16

Good for you! Once seedlings have developed 2-3 pairs of true leaves, they should be thinned or transplanted to stand 6-12 inches apart. Be ruthless or you won't have healthy basil!

Fill a food processor with basil leaves, adding just enough EVOO to hold the mixture together, like a thick paste. Put in an air-tight container and freeze. (I like to freeze it initially in an ice tray, then transfer the cubes to a freezer bag, so I can take out a little at a time.)

I found the best way to freeze basil is to use small jars I saved. I put a top layer of olive oil on. Be sure to leave a half inch head space before sealing with the cap.

I used to have Basil, but one day, tiny brown and black dots showed up. The leaves started to shrink and shrivel up. Microscopic little white bugs (I am 100% sure they are definitely not aphids or leafhoppers, they were much smaller) started to crawl around, and soon all the leaves were gone, leaving a skeleton of a plant. What happened?

Sounds to me as whiteflies if they are white and look like white powder/dust when u shake the plant almost impossible to get rid of unless you treat but then thebasil will be bad to consume a good way to keeping pests off before they do make a hme of your plant mix soap and water and spray on your plant everyday

By Anonymous

Sounds like it could be spider mites? They can look brown with black spots...they're leaf damage leaves brown thinning with black specks I believe. Maybe their larvae are white

It's impossible to exactly explain the failure of your basil plants to thrive. Like so many plants, this too can be tricky. It can be vulnerable to downy mildew and there is nothing you can do about it. It can be brought in on transplants, in infected seed, or as airborne spores.
The best thing you can do it try again. Use good composted soil, wet but don't drown the plants, give them adequate sun.
And it could be something else, too.
It's tragic, but better luck next time.

I live in the Central Valley in California (Fresno to be exact) and we get pretty hot summers. What can I do to protect my outdoor basil plant from dying?

By Anonymous on April 28

I wouldn't worry about it. I live in Arkansas, and last year it got up to 112 degrees--my basil flourished. Just make sure it get enough water.

I'm not sure if my basil plants are growing correctly, what is the average height it should be during the 1-2 week point?

By Almanac Staff

It takes a week just for the basil seeds to germinate and see the seedling start to emerge. You should see two broad seed leaves, each shaped like a capital D, borne with flat sides facing each other.

I have one growing in my livingroom, I get snow where i live in the winter, so this year i thought i would try and keep one inside. so far it is doing great, i have had it for about month and a half. any thoughts?

By Almanac Staff

Basil can grow indoors if has plenty of bright light. Some folks install artificial lights and run for 10-12 hours daily. If your basil grows, you'll enjoy harvesting the leaves indoors for cooking. Keep in mind that basil is an annual so it will eventually finish flowering and die. Then you start again seeding in the spring.

I like to store my basil by making large batches of pesto. I then wrap it in plastic and shape it into a roll and freeze. When I need some, I slice off what is needed easily.

This is the first time I have grown basil. I have 4 plants of sweet basil and the above talks about pruning the branches mine has no branches just bunches of leaves and they are sprouting their 4th set with little one inside can someone explain how to prune the basil thanks

By Almanac Staff

Every time you cut some basil leaves to eat, cut right above a pair of leaves and new growth will come. For culinary uses, prune basil every few weeks to encourage maximum production; just pinch off the flower buds as soon as they begin to emerge.

Tried & true method.
In a clean glass jar
Place a layer of basil leaves.
Add a layer of salt.
Then a layer of olive oil.
Add your next layer of basil repeating the step sequence until the jar is 2/3 full.
Finish with a layer of oil.
Cap & place in the refrig.
Stir the leaves once in a while leaving the top laver of oil covering the leaves.
In a few weeks you will have potent basil oil.
Add a tablespoon/teaspoon of oil (leaves to if desired) to any dish for summer flavor in the winter.
Salt your dish if needed after tasting.
Remember to top off the oil to keep the leaves submerged or they will brown.
This will keep till the next years harvest & beyond
Enjoy!

How thick should each layer be in a one quart jar, or, I guess, in any jar? Thanks.

Thanks so much... first time growing Basil will try this method this year. I love to see herbs in oil but never knew how to do it.... thanks again!i

Be generous with the salt layer.
Many times I just use the oil on top to cook my eggs or add to a salad.
Remember to use a good olive oil!

When I naturally dry sweet basil, sometimes the leaves turn brown. How can I keep from this happening?

By Almanac Staff

 Make sure that you're washing the basil leaves before you're drying them. Also, make sure you're keeping them in a cool, dry place, and they should keep for weeks.

By rcain

I have some white sticky sacks on the basil but they never get hard. I am sure it is a bug of some kind but not sure what. They wash off real easy but I would like to know what they are and how to get rid of them instead of washing them off as they are there again in the morning.
