Just as a watched pot never boils so a watched tomato never ripens. The virtue most important for gardeners is patience. Staring doesn’t work. Tomatoes aren’t easily intimidated. Sometimes those beautiful hard, yellow globes seem to hang on the vine ad infinitum. Tomatoes ripen by warmth, not sunlight, so the wait is for warmer temperatures which can be a difficult wait in the High Country. Nature, as with its Creator, has its own purposes, and they may not be the gardener’s. Gardening is not instant gratification.
However, some things can be done to assist the ripening and make the gardener feel useful. Tomato vines do a lot better, as with nearly everything else, if they are given the right care, such as a few light feedings during the growing season. Tomatoes don’t do well on a diet of fat fast food. The diet should be lean on nitrogen. Nitrogen causes the tomato vine to blimp out without producing many tomatoes, resulting in a high maintenance trophy which hangs around looking lush but doing nothing.
Regular watering avoids the feast and famine of wet and dry cycles which stunt the vine and thwart fruiting. It is important to avoid getting the leaves wet when watering because the sun might scald the leaves and wet leaves are an invitation to disease. Tomato vines are liquid feeders so dry fertilizers should be well watered-in.
Pruning the vines helps with the harvest. The principle in pruning is the same as it is in training athletes, an efficient use of energy. If runners wave their arms, they impede their speed and waste energy. A lot of excess branches drain energy away from producing fruit. Non-producing branches near the ground look messy and siphon off energy.
The purpose of pruning is to open up the tomato vine so that warm air can circulate within the vine to prevent moisture-borne diseases and to ripen the fruit. Also, one of the purposes of the leaves is to shield the delicate flowers and fruit from direct sun light. Pruning should not produce a skinny vine, but rather a vine open to the air and clothed enough with leaves to protect the fruit, something like sensible clothing.
Sometimes it is useful to think of a tomato vine as an adolescent in matters of nutrition, dress, cleanliness, and growth. Vines don’t do well in messy surroundings. Keep the space clean and picked up because filth is an avenue for disease. A sour smell is never good whether from tennis shoes or rotting leaves and fruit.
Ripening occurs, as with adolescents, in spurts. All of a sudden, wham, bam, overnight a tomato turns from hard yellow to red luscious. When it’s growing, it’s a hard yellow. On reaching full size the tomato turns green and begins to ripen because of an internally produced gas called ethylene. In the twinkling of an eye a sweet, docile child can turn into a defiant adolescent because of those internally produced hormones. When the fruit turns half green and half pinkish red, the tomato stem is sealed off from the main vine. From then on the ripening takes place either off or on the vine. Waiting for the tomato to turn red on the vine is not a vine ripened tomato because the tomato matures of its own inner dynamics. Sometimes it is better to harvest tomatoes in this “breaker stage” to prevent splitting and to control the ripening process indoors.
Tomato vines are the gardener’s babies. Staring, intimidation, and cursing don’t produce children in which a parent can take pride. If they are well cared for and loved to a fault, eventually they will do well. However, eventually everything is in the hands of an Unseen Power who has no name and over whom a gardener has no control.
