Learning how to grow tomato plants from seed is a rite of passage for serious and recreational gardeners alike. This article outlines the basic steps involved in germination, planting, thinning and watering. Here are some tips to help you grow plants that are healthy and yield a bounty.


Thinning tomato seeds is an important step in growing your plants. This process can take a lot of time and patience, and procrastination is never a good idea. If you do not want to lose any of your plants, you should thin them at the appropriate time. Follow the instructions on the seed packet or growing guide for precise spacing.

Thinning tomato seeds is crucial because it helps them grow more efficiently. Plants that are too close to each other are more likely to compete for air, water, and nutrients. This can lead to a number of problems, including disease and pest infestation. Powdery mildew, for example, thrives in crowded conditions and can spread from leaf to leaf through rubbing together. Not only does crowding hurt plants, it also slows their growth.

Tomato seedlings should be thinned as soon as they show two sets of leaves. You can do this safely by snipping off the reject stems above the soil line. This way, you will leave one healthy tomato seedling in each cell. The remaining seedlings can be transplanted to other containers. Once you have a few tomato plants, make sure that they have ample light and sufficient ventilation.

To prevent your tomatoes from becoming sick, rotate your seedlings every few days. Ideally, you should plant your seeds at least six to eight weeks before the last frost date in your area. A temperature of 70 to 80 degrees Fahrenheit is ideal for the growth of tomato seedlings. You can use a heating mat if necessary to keep the seeds warm.

The presence of true leaves means the seedling is further along, but that doesn’t mean it’s the strongest one. A seedling that is weak is likely to be a late bloomer. If you choose to thin seedlings too early, it will stunt their growth.


Watering tomatoes is a complicated process. It requires constant monitoring and adjustments. Tomatoes need water daily, but the amount you need to give them varies depending on temperature and rainfall. For optimum results, water them in the morning before it gets too hot. This will help prevent the development of disease and prevent the plant from drying out.

When starting tomato seeds, make sure you choose a pot that is not too big. A 3 or 4-inch pot is ideal, as it will not dry out as quickly. You can also use a mister to moisten the soil while watering. Be careful not to over-water, however, as you don’t want to drown the seedlings.

When watering tomato plants from seeds, always check the soil’s condition before watering. You want to make sure that you water the soil deeply, but not so deeply that it oversaturates. Watering tomato plants is not difficult, but it does take a bit of trial and error, so make sure to follow your instincts.

Once the seedlings are tall enough, fertilize them. If you do this, make sure that you apply water-soluble fertilizer to them. Be sure to mix the fertilizer at half its recommended rate. When the plants are large enough, you may want to transplant them to bigger containers. Don’t let them become pot-bound; this can stunt their growth.

It is important to water tomato plants properly to prevent weeds and disease. Watering tomato plants with a watering wand or rose spout can help you get the best results. It also allows you to water your plants gently, without disturbing their roots.

Protecting young plants from wind

If you are growing tomato plants from seed, one way to protect them from wind is by staking them. Staked plants are often more vulnerable to wind damage, but there are other ways to protect young tomato plants. One method is to use a cage. This will provide a good amount of support for the tomato plants. It is important not to stake the tomato plants in the cage, though, as this can break their branches.

Besides protecting your young tomato plants from wind, you should also keep an eye on the weather forecast. This can help you to decide when it is time to transplant your plants. If the weather is going to be cold and windy, it is best to avoid transplanting them until after the first frosts have passed. Cold air and soil temperatures stress out warm-weather crops and can cause them to be susceptible to disease and pests.

In addition to staking your young tomato plants, you can also place windbreaks on the sides of your container. This is particularly useful if the wind is coming from the north. The wind from the North Easterly direction tends to be cold and dry in winter, while the wind from the South Westerly direction is warmer and less drying.

Another way to protect your young tomato plants from wind is to use a cloche. A cloche is a protective covering made of plastic milk jugs or juice bottles. It helps prevent the wind from damaging your seedlings, while trapping light and warmth in its interior. This will promote growth and development of your tomatoes.
