As for many plants, fertilizing tomatoes can help them to grow strong and plentiful. It can help ensure that your plant will produce plenty of fruit that is delicious. Fertilizing is something gardeners of all experience levels can do.

Tips For Growing Tomato Plants

When planting your tomato plant, wait for the temperature of the soil to be at least 60 to 65 degrees Fahrenheit. Plant them in an area where they will receive lots of sun, as tomato plants love the sun and will grow more fruit if grown in a sunny area. They can grow in a garden bed or in a medium to a large pot.

Most tomato plants need about an inch of water a week in order to grow healthy. The best time to water your plants is in the morning, as they are more receptive to moisture at this time. They can also benefit greatly from a layer of mulch.

The Best Time For Fertilizing Tomato Plants

Another important part of growing tomatoes is fertilizing them. Tomato plants should be first fertilized when you first plant them in the garden. This will give them the boost they need to grow successfully.

After fertilizing them upon planting them, you can wait to fertilize them until they begin to produce fruit. Once they start to grow fruit, add fertilizer every one to two weeks for as long as your tomato plant is still growing and producing fruit.

Though seedlings will need fertilizer right away, it is often best to wait a bit for transplants. If you are transplanting tomato plants, it is ideal to let them grow a couple of weeks before fertilizing to allow them to adjust.

Tomato plants need lots of nutrients in order to grow into healthy, producing plants. In most cases, soil on its own does not have enough nutrients to provide tomatoes with everything they need. This is why it is important to provide fertilizer for your plants.

If you have soil that is correctly balanced or has a higher amount of nitrogen, look for a mixed fertilizer that is 5-10-5 or a 5-10-10. This will contain higher levels of phosphorous and lower levels of nitrogen and potassium. When shopping, it is best to look for fertilizers specifically made for tomato plants.

Organic fertilizer is another great option for your garden, as it is kid and pet safe. Though you can buy organic fertilizer, you can also make your own. Coffee grounds, eggshells, compost, manure, and fish emulsion all work as natural fertilizers for your garden.

If you want to see if your plants need fertilizer, you can dig a hole, put a bucket in it, and add fertilizer. If there is no change, your plants don't need any. You can also make a spray bottle with water, and spray it into the holes. This will help keep the plants healthy, but will not necessarily increase their size.
