To many gardeners, basil is the king of herbs. Basil can play many roles while basking in the sun. Some varieties are highly ornamental in the summer landscape, branches of basil can add interest to bouquets, and, of course, basil is essential in the kitchen. Hot summer days become more bearable when the cook is able to pluck fresh basil and use it in pestos, herbal vinegars, vegetable dishes and, most heavenly of all, nestle the leaves between slices of fresh bread along with red, ripe tomatoes and sweet onion slices.
Members of the mint family, basils are native to India, Africa and Asia but have a long, rich history of legend and use worldwide. In Italy, a pot of basil placed on a balcony signaled that a woman was ready to receive suitors. Basil is often considered a symbol of love, but in Flora's Dictionary author Kathryn Gips cautions that those who dabble with the language of flowers must be sure the message's recipient is on the same wave length as the sender...Basil may also be used as an emblem of hatred for an enemy. In India holy basil is considered a sacred herb and at one time was used to protect the dead from evil. It is still found growing around temples.
Early Greeks and Romans believed that a good basil crop would only develop if the gardener shouted and cursed while sowing the seeds. In Austin, Tx this is not necessary, although it may happen if fire ants have invaded the newly prepared basil bed. Basil will thrive in a sunny, well draining location. An evenly moist soil will ensure lush growth. The seeds will sprout easily and quickly when the days grow warm and sunny. Unfortunately, snails love basil even more than cooks do. If this is a problem, use large transplants or protect the seedlings with rings of diatomaceous earth, sharp egg shells or the wonderful copper striping commercially available for this purpose. Pinch the basil frequently to encourage leaf growth and prevent early flowering. The flavor seems to change as blossoms appear. You can let a few flower stalks go to seed for collection for next year's crop, but be aware that basil varieties are promiscuous and several types of basil grown together may yield babies unlike any of the parents--but who knows, it could be an amazing new taste in the garden! Basil cuttings also root easily in potting mix or water.
Recently, fusarium wilt of basil has appeared in the United States. The pathogen, Fusarium oxysporum f. sp. basilicum, is specific to basil and will not harm tomatoes, eggplants or peppers, although it might be prudent to avoid planting other mint (Lamiaceae) family members in infected soil. An infected plant will usually show stunted growth before wilting. Later disease stages feature brown cankers. If your basil suddenly wilts and dies without an apparent cause, be concerned, but don't forget that most basils will turn black at the mere whisper of a 40 degree night. An article about fusarium wilt appears in the Herb Society of America's 1997 issue of The Herbarist.
Basil is best used fresh. Small leafed varieties
can be grown in a pot on a sunny windowsill during the winter. To
preserve summer's flavor for winter make plenty of pesto and freeze it.
Chunks of pesto are easily thawed for use on pasta or to flavor sauces.
Basil and oil puree may also be frozen for winter use. Use two cups
of dry, packed basil leaves and 1/4 to 1/2 cup of olive or canola oil.
If basil must be dried, Madalene Hill and Gwen Barclay (authors of Southern
Herb Growing) recommend placing the leaves on a tray or screen and
drying at room temperature. The leaves should be stirred twice a
day. Covering them with a sheet of newspaper will help retain their
color. Basil releases it's essential oils at 85 to 90 degrees so
it should not be dried in the oven or microwave.
