Basil is normally easy to grow. Normally you would plant it in your area from April to July.It doesn't like frost but, as it is a soft herb it doesn't like extreme heat and drying winds either. Try planting it where it gets morning sun and is protected from harsh conditions. A spot that gets light shade would also be good. Basil likes fertile, well drained soil and will reward you if the water supply is evenly damp but not wet. Sowing seed directly where it is going to grow is the best as direct-seeded plants will always do better than transplants. Trust this helps.

I am in Tampa, and I am growing so much basil from seed I am now drying it. I have mine in pots in full sun and water daily and then I have some in the ground in semi shade as an experiment.

Basil is normally easy to grow. it likes moist, fertile soil and, while it won't tolerate frosts, it will burn with heat or drying winds. Select a spot that gets morning sun and protection later in the day then sow seed thinly in this spot. Sowing seed direct is more successful than using a seed bed or pot then transplanting as the plants aren't subject to root disturbance and transplanting shock.

I have had no problem seeding basil indoors. They come up easily. My plants grow fine. But after I pinch of all the god leaves, it produces a little more then stoppes producing altgether. What did I do wrong? Everone says to just keep pinching to help encourage new growth. That doesn't work for me. The plant just dies before producing god regrwth.

The only reason you should pinch basil is if it starts to get leggy. Let it grow and take the top leaves for your recipes. I plant lots of it and let it go to seed. The seeds restart themselves in the same pot.

Don't pinch or cut the leaves off. Instead use scissors to cut the *stem* just below the pair of leaves you intend to harvest. Then, in the kitchen, pick the leaves off the stem while washing them.

I had the same problem at first. Most instructions aren't very clear on the details. The trick is to wait until there are 3-5 sets of true leaves on the seedling. Then, only cut off the top pair of leaves. Also don't pinch or trim until it is transplanted or in its final pot for growing. For the second "pinch," wait until the suckers (like on tomatoes) have 2-3 new sets of leaves, at least. Always use scissors or shears, btw. A good rule of thumb is to never remove more than 1/3 of a plant's leaves at a time, if you want it to keep growing. Once I figured out how to trim my basil plants, they went nuts within a couple of months. Now I have more basil than I can handle!

I live North Shore Auckland. I've tried to grow allsorts of veg & herbs in pots from seeds outdoors with mixed success. The basil was one of my dismal failures. I now grow all my seeds indoors until the weather is warmer and the plants are well established. I find starting indoors is a lot more convenient for keeping an eye on progress. Regards basil, I find the seeds grow well starting indoors but take a while to get established once outdoors, then they go crazy! Since starting indoors I now have few failures but there are some things to be aware of: Light - needs good light so the seedlings don't become leggy. Be aware that near glass (windows/doors) can cause burn damage. Turn the pots around regularly so the plants don't lean. Don't over crowd, thin out seedlings if necessary. Temperature - Note the soil temperature required to germinate. Overheating during the day, too cold at night. I put a box over the pots at night to protect from sudden drops in temperatures. Ventilation - Ensure good air flow to minimise risk of disease, be aware of cold draughts coming from open windows at night. Watering - My seeds are sown in different sized pots/trays depending on what they are. I use
