I have about a 3 ft tall tomato plant that has produced only one tomato so far, it has numerous blooms but they seem to dry up without producing a tomato. I try not to water it unless the soil seems dry and I shake the plant also, nothing seems to be working. Please help. Thanks

Tomatoes are warm-season plants that need nighttime temperatures above 50F degrees before they'll set fruit. On the other hand, if daytime temperatures soar above 90F, the pollen is rendered sterile and no fruit will form. If the blossoms are falling off your plants it's a sign that the temperatures are still too cool, or too warm! Another remote possibility is that even though your plant is 3' tall, it may not be mature enough to set fruit - but it will when it's ready. There's a spray called blossom-set that will sometimes help. You might want to try it - or you may just want to wait until a little later in the season for the plants to begin producing.
