Tomatoes are the most popular vegetable in home gardens across America. It’s important to understand common tomato terms, often seen on tomato plant tags and the basics of growing tomatoes…. the more you know the better you’ll grow. Now through mid-July, you can plant extra tomatoes for later harvests in fall. Some tomato varieties can ride the heat-wave with you, setting fruit even as the temperature rises. 

Tomatoes need the right combination of good soil, water and heat. Use transplants. They’re faster than starting from seed and easier to grow. Transplants offered in biodegradable pots are planted directly in-ground, preventing transplant shock and saving millions of pounds of plastic from landfills. Find a sunny location (at least six hours of sun) with good drainage, and if you plant tomatoes each season, it’s a good idea to rotate the spot in the garden where you plant them.


Tomato plants are classified as either indeterminate or determinate. Indeterminate plants grow all season, continuing to bloom and produce fruit as long as weather conditions are favorable. Determinate plants are the compact bush type. They grow to a certain size, set fruit, and stop growing, bearing fruit all at once. This type of tomato is popular with gardeners who like to can and makesauce.

Tomatoes are often designated by the terms early, middle and late, which refer to when the fruit will be ready to harvest. Early season tomatoes are the first to ripen, late season are the last to ripen and middle season types fall somewhere in between. Planting some of each type is a good strategy for enjoying ripe tomatoes throughout the summer.  

Tomato Types

Heirloom tomato – Any tomato that is at least 50 years old and is not a hybrid, like “Mortgage Lifter”, this heirloom tomato got its name because a mechanic in West Virginia who developed the variety made so much money selling the seeds he paid off his mortgage!

Hybrid tomato – A tomato bred by crossing varieties. Hybrids offer better disease resistance, higher yield, and other improved traits.

Now it’s time to pick your plants:While tomato lovers have a seemingly endless list of varieties to plant in their gardens, tomatoes fall into three basic categories: small salad (cherry) tomatoes, slicing tomatoes and thick-walled tomatoes ideal for making sauces. It can be confusing to pick the perfect tomato best suited for your needs; you might want to check out the “Tomato Chooser” on Bonnie Plants website (…you can sort through tomato varieties to find just what you want, if you check off the traits that you’re looking for, the Tomato Chooser will do the work for you, bringing up all the varieties that match.

If you’re temperatures are rising, choose a heat-set tomato variety that’s able to set fruit in high temperatures compared to many other varieties.

1. Prepare your plot: Loosen the ground to create a welcoming bed for roots to grow. You can add three or four inches of compost or other organic matter, especially in clay or sandy soils. Then dig a hole that is as deep as the plant is tall because you are going to bury two-thirds of the plant.

2. Slip plant from pot if in plastic: Gently remove the plant by slipping the plastic container from the root-ball. Don’t tug on the plant stem; this can sever it from the roots. If the roots are growing out of holes in the bottom of the pot, tear or cut them away and squeeze and twist the pot as necessary to work it from the roots. If your plant is in a biodegradable pot, just tear off the bottom of the pot to make sure that roots are in instant contact with the soil.

3. Bury two-thirds of the plant: Set the plant in the hole deeply enough so that two-thirds of it is buried. Roots will sprout all along the buried stem to make a stronger plant. You can pinch off the lower leaves if you prefer, but it is not necessary.

4. Don’t forget to fertilize: Mix fertilizer into the soil that you will put back into the hole.  It is best to fertilize according to recommendations from a soil test, but if you don’t have that, use a timed-release fertilizer, which doesn’t leach…or use an organic fertilizer at the rate recommended on the label.

Your tomato plant is almost ready to grow–When you’re done, two-thirds of the entire plant will be buried; only the top of the tomato plant remains above ground.

5. Water Well: Water thoroughly at soil line. This is very important to help settle the soil and start the plant.

6. Maintain your mulch: Mulch with pine needles, straw, or compost to help keep moisture in the soil and prevent weeds. Mulch should be 2 to 3 inches deep for effective weed control.

Plant tomatoes that work for you, they’re fun to grow and the taste of a home-grown tomato is definitely more delicious than any store bought tomato.  Enjoy the fruits of your labor!
