Select a site with full sun and well-drained soil. In very hot climates like ours here in Barbados, light afternoon shade may help prevent blossom drop. Prepare the garden bed by using a garden fork or tiller to loosen the soil to a depth of 12 to 15 inches, then mix in a 2- to 4-inch layer of compost.
For best flavor, harvest tomatoes when they are firm and fully colored. Fruits will continue to ripen if you pick them when they are half-ripe and bring them indoors, but the flavor is often better if you allow fruits to ripen on the vine.
If you bought seedlings then plant your tomato plants deeper than they come in the pot, all the way up to the top few leaves. When planted this way, tomatoes are able to develop roots all along their stems. And more roots make for a stronger plant.
