Growing tomatoes in containers

Slice them in a salad, simmer in a sauce, or nibble them straight from the vine, tomatoes are the taste of summer...

If you love the taste of fresh tomatoes but think you don’t have space to grow them, you will be delighted to know that there are tomato varieties for just about any space, with mature heights from 6 inches to 6 feet tall and above. All may be grown in containers and several varieties may even be grown in hanging baskets. Some advantages of growing tomatoes in containers are better control of soil type, watering and drainage. It is also easier to monitor for possible disease and insect infestations.

Tips for Success

  • Tomatoes love sun. Provide a location with at least 6 hours of direct sunlight per day.
  • Plastic containers or glazed pottery retain moisture best - this can be an advantage as plants mature and temperatures rise. Use good quality, well-draining potting soil. Some gardeners add compost, but never more than 25% of the total growing medium.
  • When planting, mix an organic vegetable fertilizer into the soil. Enhance growth and fruit production with an organic seaweed extract. Seaweed extract products may be applied as a drench or a foliar spray early in the day and repeated every two weeks throughout the growing season.
  • Check plants daily as they mature. Soil should be evenly moist but not soggy. When watering, thoroughly water the entire root zone. Make sure the container drains well and they do not sit in water. It is best to water in the morning so plant roots can take best advantage of the moisture and soil temperatures are not cooled by watering during the peak growing time of day.

Tomato Terms

(H) Heirloom – varieties whose seed strain has been preserved intact for 85 years
(D) Determinate – varieties tend to produce fruits which bear most of their fruit over a 4 to 6 week time. Plants are typically smaller and usually do not require staking.
(I) Indeterminate – varieties keep growing and producing fruit over a very long season. They need to be staked or put in cages and can be grown in containers or in the ground. Indeterminate varieties produce best in containers of at least 20” or 22” in diameter.
