Tomato Growing Guide

As anyone who has ever experienced the delicious flavor of a tomato fresh from the vine will know, there is nothing quite as good as garden-grown tomatoes. It’s no surprise that tomatoes are America’s favorite homegrown food. While there are many varieties, and every veteran gardener has slightly different methods they swear by, you can easily be successful by understanding some of the basic needs of the plants. Whether you are new to gardening or a veteran, we’ve got your guide to the ins and outs of growing tomatoes at home.

Sowing and Planting

You can grow tomatoes from seed or starter plants in containers or in the ground. If you are starting in May, you will want to plant a starter plant. Whether you are growing in the ground or in a container on your balcony, you will want to plant your tomatoes in soil with added compost, lime and fertilizer. 

Each gardener has their own recipe, but lately I am a fan of Bumper Crop as it has all of these ingredients in one bag and is certified OMRI (Organic Materials Review Institute) organic. When planting in the ground, dig into and loosen the soil at a depth of 8 to 12″ and mix in a 1 to 2″ layer of Bumper Crop. When growing in pots, mix 80 to 90% potting mix with 10 to 20% Bumper Crop. 

Starting from seed? See our resources on starting seeds indoors and starting seeds outdoors. If you’re planting in containers, see our guide on planting tomato transplants in containers for more information on getting started. 


Tomatoes need a minimum of 5 hours of direct sun each day, but even more is better.


Check the soil often and keep your tomatoes consistently moist throughout the growing season. If it feels like a moist or wet sponge, your plant has a good amount of water. Too much water can cause disease and will cause your tomatoes to crack. Too little water on the other hand reduces the quantity and quality of your tomatoes and can lead to blossom end rot.

Space and Support

Tomatoes are vines that continue growing throughout the entire summer. It’s not unusual to have tomato vines reach 8 to 10′ by the end of the season. Growing tomatoes in “cages” that help support the plant is one of the easiest and best ways to hold the plants upright, off the ground. You can also support the plants with stakes or on a trellis. A few varieties, such as ‘Celebrity’, ‘Rutgers’ and ‘Patio’ are smaller (determinate) plants that are good for limited spaces.

Growing Tips

While your plants are growing, there are a few tasks you will want to complete regularly as well as a few issues to keep an eye out for that commonly cause problems for tomato gardeners.


 Apply Tomato Tone every 4-6 weeks throughout the growing season to keep your tomatoes fed with plenty of nutrients.


Bumble bees are the primary pollinators of tomatoes, and you will need to attract them if you do not want to pollinate your plants by hand to ensure a good harvest. To bring the bees, plant zinnia, hyssop, portulaca and other flowers near your tomato plants.

Pest and Disease Prevention and Solutions

Fungal Diseases

Tomatoes are susceptible to several fungal diseases. Here are a few steps you can take to prevent your plants from becoming infected:

  • Place your tomatoes 3 to 4 feet apart, allowing plenty of room for good air circulation. 
  • Mulch around the base of your plants to prevent contact with the soil, where fungal diseases may reside.
  • Avoid prolonged periods of leaf wetness as it can promote infection and disease spread. You can do this by watering in the morning so that the sun dries the leaves, or by watering at the base of the plant so that the leaves do not get wet. 


Tomato hornworm, aphids and mites are the most common pests that can affect tomato plants. You can remove hornworms by hand and manage aphids and mites with insecticidal soap applied according to the package directions.

Squirrels, Chipmunks and Birds

A number of common garden critters love tomatoes, and will take a bite (or several) out of your plants. If they are getting more tomatoes than you are, consider picking them early, at the first sign of color, and let them ripen up indoors in safety.

Growing Tomatoes in Containers: A Video Tutorial

Plant specialist David Yost demonstrates the steps for planting tomatoes in containers that can be placed on a patio, balcony or deck.


Vegetable Gardens in Small Spaces: Tomatoes

Tomatoes are one of the most popular fruits and vegetables among gardeners as they are both beautiful and delicious! Even if you have limited space, you can grow beautiful tomatoes with a container, adequate sunlight and a little planning.

Tomatoes can grow in a variety of conditions, but will produce the best fruit in a location with 6 to 8 hours of sun per day. Before you begin your tomato container garden, check your yard or patio at a few different times throughout the day to determine the best location for your plant.

Step one: Choose your tomato

You can grow just about any kind of tomato in a container if you are willing to work with vines that can reach 8 feet tall or more. I like to grow the Celebrity variety in containers for its hardiness, flavor and manageable size. ‘Celebrity’ typically grows to about 5 feet, making it a manageable choice.

Step two: Gather your supplies

Before you begin planting, you will want to make sure you have the following items:

  • Container: Your container should be a minimum of 16” in diameter for one tomato plant. With tomatoes, bigger is always better when it comes to containers. Today I’m using a plastic pot, but you can use almost any container as long as it has a hole in the bottom for drainage. You can also use an EarthBox, which has a sub-irrigated watering system that can increase time between watering.
  • Potting soil: We recommend using a lightweight potting soil, such as Pro Mix Organic Vegetable and Herb, for container-grown tomatoes. For one tomato plant in a 16” pot, you will need two 16 qt. bags of potting mix.
  • Small square of landscape fabric: Place this over the drainage hole in the bottom of the pot to prevent soil from escaping and keep your patio clean. This will also prevent critters from coming into the pot.
  • Tomato cage or other support structure: To keep your tomato contained within the pot, we recommend using a tomato cage or a plant stake to support the vine.
  • Fertilizer: I like to use an organic fertilizer, such as Espoma Tomato Tone, for my edible gardens. You can also use an inorganic, slow release granular, such as our Merrifield Flowering Plant Food or Osmocote.
  • Granular lime: I like to mix lime in with my tomatoes to prevent disease and boost growth.
  • Squirrel repellent: I have lots of squirrels in my yard so I use a squirrel repellant to discourage them from tampering with my tomato plant. I like the I Must Garden brand as it’s organic.
  • River jack stones or seminole chips: You’ll use these to cover the top of the container surface. This will protect your plants from squirrels and preventing dirt from washing out of the top of the pot.
  • Hand shovel
  • Gardening gloves
  • Watering wand and hose

Step three: Plant

Since your container can be heavy once its filled with the soil, we recommend setting the container in place before you plant your tomatoes.

  1. Place your piece of landscape fabric over the drainage hole in the bottom of the pot.
  2. Fill your container 2/3 of the way with potting soil.
  3. Add your fertilizer and lime to the potting soil and mix with your hand shovel. Be sure to follow the instructions on the label to determine the appropriate amount of fertilizer and lime to mix in.
  4. Add your tomato plant. Break up the roots and remove the bottom set of leaves before placing your plant in the pot. You can cover your tomato with soil all the way up to the second set of leaves.
  5. Top off the container with soil, but keep it an inch from the top of the container to keep it from spilling over the sides as you water.
  6. Place your tomato cage in the pot. You will want to do this right after planting to prevent the cage from damaging the root system of the tomato.
  7. Cover the surface of the soil with a half-of-an-inch of small river jacks or seminole chips.
  8. As an extra layer of protection, spray your tomato with squirrel repellent.

Step four: Water and nourish

Once your container is set, water it thoroughly. Run the water over your container, letting it drain out of the bottom. Tomato plants need to be watered frequently to maintain consistent moisture in the soil. The soil should not be allowed to dry out. During hot weather, you will likely need to water your tomato plant daily.

For the best tomatoes, we recommend feeding your plant every 2-4 weeks with fish emulsion.

Your plant will be ready to harvest later this summer, and will continue to produce fruit through the end of the season.

Watermelon Salad for National Watermelon Day

We’re celebrating with this fresh-from-the-garden watermelon tomato salad! It’s one of our favorites and is fresh all summer long. We hope you enjoy!


  • 1 small seedless watermelon
  • 4 heirloom tomatoes
  • 1 bag baby arugula
  • 1/4 pound feta cheese
  • 1/3 cup extra virgin olive oil
  • 1/4 cup sherry vinegar
  • 1 tbsp. pink peppercorns
  • 1 tbsp. honey
  • 1 large shallot
  • 1 tbsp. kosher salt
  • 1 tbsp. Dijon mustard
  • 1 bunch chives
  • 3 garlic cloves


In a bowl, add finely chopped shallots, minced garlic, salt, sherry, honey, mustard and crushed pink peppercorns. Using a wisk, slowly add the extra virgin olive oil until combined. If this mixture separates, that’s normal. Add the chives.

In a separate bowl, add the watermelon and tomatoes, which both should be cut into roughly 1 inch pieces. Crumble feta cheese into the watermelon/tomato mixture and toss with some of the vinaigrette mixture until coated. Mix with the arugula.

This is a great recipe to make a day in advance. Just store the watermelon mixture separate from the arugula. You can substitute lettuce for the arugula or use the tomato of your choice.
