Tips For Growing Tomatoes

Growing tomatoes and other articles about tomatoes are offered a few times on our blog – mainly because they are such a favorite item to grow. In Wisconsin, we relish the summer days when we can take a walk to our gardens and pick them right off the vine – nothing comes close to the flavor of fresh!

Our friends at Hybels Greenhouse in Michigan, who supply many of our plants offered us a few of their tips on growing tomatoes.

Growing Tomatoes

For best results, tomatoes thrive in warm temperatures with at least 6 to 8 hours of direct sun. Always wait until the last frost has passed to plant your tomatoes.

Plant Types

Right after planting, use a tomato cage or stake to support your tomato plants. When purchasing your tomato plants, read the labels first to discover if they are Indeterminate or Determinate. This will help you determine how large your plants will ultimately grow and the support you will need.

Indeterminate Type Plants

These plants will need large tomato supports as they grow to 6 feet plus and produce a large crop of fruit. These tomatoes continue growing and setting fruit all season.

Determinate Type Plants

These tomatoes have a more compact and bushier growth habit perfect for pots on the patio or hanging tomato bags and baskets. They set fruit over a 4 to 6-week period only and then stop, which makes them a great choice for using in pastes and for canning. Medium size supports are recommended to help with the amount of fruit they produce and to keep the vines off the ground.

Space Requirements

It is important for your plants to have plenty of room to grow. Having extra space surrounding your plants increases air circulation, which helps prevent diseases from occurring. Space the long growing vines of indeterminate tomatoes about 3 feet apart. Compact, determinate tomatoes can be grown about 2 feet apart.

When growing your tomatoes in containers, use an 18 to 24-inch size pot for an indeterminate variety, or a 16 to 18-inch size pot for a determinate variety. For best results, fill containers with a premium prepared soil mix. Smaller size pots may be used but are not ideal as they will dry out quickly and require daily or even twice daily watering.

To save on space, leaf lettuces and spinach can be grown in the partly shaded area near your tomatoes. The lettuce and spinach will be ready to harvest soon after the tomatoes are planted. In addition, try planting basil near your tomatoes as it will naturally repel whiteflies, spider mites, and aphids. The basil will also improve pollination for your tomatoes as it attracts bees and even improves tomato health and flavor.

Feeding

Tomatoes are heavy feeders and need a constant supply of nutrients. Mix 3 to 4 inches of compost into your existing soil to provide nutrients and retain moisture. Have your soil tested to determine exactly what type and how much fertilizer you should give your tomato plants. If you decide not to do a soil test, apply a slow release fertilizer to the soil at the beginning of the season. Make a second application mid-season, if needed.

After Planting

Immediately after planting, water your tomato seedlings thoroughly to help them settle into the soil. Throughout the growing season water regularly, with at least an inch of water per week. Feel the top inch of soil; if it is dry, then it’s time to water. Lastly, cover the ground with 2 to 4 inches of a straw or shredded leaf mulch to minimize weeds and keep the soil evenly moist.

Helpful Hint: Did you know, for an extra strong tomato plant, you can bury two-thirds of the stem when planting? This allows extra roots to sprout along the buried stem, making a stronger plant that is better able to take in water during a drought. *This planting method works only with tomatoes and tomatillos, and not with other vegetables.

Prolonging Harvest

It is important to read the tomato label to discover how long it will take your tomato to grow and produce a harvest. To prolong your tomato harvest, combine early season varieties, such as Early Girl (matures in approximately 59 days) or Independence Day (matures in approximately 49 days) with later tomato varieties such as Beefmaster and some heirloom varieties that mature in approximately 80 days.

Happy Growing!
