Growing tomatoes is often the impetus for starting a vegetable garden, and every tomato lover dreams of growing the ultimate tomato: firm but juicy, sweet but tangy, aromatic, and blemish-free.
(Sorry to interrupt, but we wanted you to know that this is a sample blog on a demonstration website – we have taken the content from a blog on The Spruce.)
Unfortunately, there are few vegetables that are prone to more problems than tomatoes. The trick to growing great-tasting tomatoes is to choose the best varieties, start the plants off right, and control problems before they happen. Start here with some time-tested tomato growing tips to ensure your tomato bragging rights this year.
1 Don’t crowd tomato seedlings
If you are starting tomatoes from seed, give the seedlings plenty of room to branch out.1 Yes, that means thinning the seedlings to one strong plant per cell or small pot. Snip the weaker, smaller seedlings in favor of the best grower. Crowded conditions inhibit their growth, which stresses them and leads to disease later on. Transplant tomato seedlings into their own 4-inch pots shortly after they get their first set of true leaves.
2 Provide lots of light
Tomato seedlings need strong, direct light. Days are short during winter, so even placing them near a sunny window may not provide them with sufficient natural light. Unless you are growing them in a greenhouse, your best option is to use some type of artificial plant lighting for 14 to 18 hours every day.
To ensure the tomato plants grow stocky, not spindly, keep the young plants only a couple of inches from fluorescent grow lights.1 You will need to raise the lights (or lower the plants) as the seedlings grow. When you’re ready to plant them outside, choose the sunniest part of your vegetable garden as their location.
3 Turn a fan on
Tomato plants need to move and sway in the breeze to develop strong stems. That happens naturally outdoors, but if you start your seedlings inside, you need to provide some type of air circulation. Create a breeze by turning a fan on them for five to 10 minutes, twice a day. That small amount of time will make a big difference.
Another option is to ruffle the tomato plants by gently rubbing your hand back and forth across their tops for a few minutes, several times a day. It’s a bit more effort, but their wonderful tomato scent will rub off on you as a bonus.
4 Water regularly
Water deeply and regularly while the fruits are developing. Irregular watering—missing a week and trying to make up for it—leads to blossom end rot (a calcium deficiency) and cracking and splitting. The rule of thumb is to ensure your plants get at least 1 inch of water per week, but during hot, dry spells, they may need more. If your plants start to look wilted for most of the day, give them a drink.
After the fruit begins to ripen, you can ease up on the watering. Lessening the water will coax the plant into concentrating its sugars, for better flavor. Use your judgment. Don’t withhold water so much that the plants continually wilt and become stressed or they will drop their blossoms and possibly their fruit.
5 Getting your tomato plants to set tomatoes
Tomatoes’ ripening is pretty much at the mercy of the weather, but sometimes we can help things along. Pinching off the tips of the main stems in early summer will encourage indeterminate tomatoes (those with fruit available continuously) to start putting their energy into flowering.
Indeterminate tomatoes like to grow tall before they start setting fruits, so don’t be alarmed if your tomato plants aren’t flowering for their first month or two. Pinching is also a handy trick toward the end of the summer when you want the last tomatoes to hurry up and ripen.
It shouldn’t be a problem getting determinate tomatoes (those that ripen all at once) to set fruit unless weather conditions are unfavorable and cause a condition aptly named “blossom drop.”
