Tomatoes: Fruit or Vegetable?

Fruit or Vegetable?

Fruit or vegetable? Genetically, the tomato is a fruit, but the U.S. Supreme Court ruled it was a vegetable.

Last blog I asked you what edibles you would plant if you were limited to only three.  The response was overwhelming, with tomatoes topping everyone’s list. 

This week, I’m sharing a few bits of tomato trivia and a number of gardening tips for big, healthy harvest.

In 1893, the United States Supreme Court ruled that since tomatoes are most often served during the main part of the meal, either alone or with vegetables that tomatoes must be vegetables. Tomatoes are really fruits biologically speaking, but either way they are delicious!

The first wild tomatoes found by explorers in Mexico were yellow and small.  Red, pink, black, green, ivory, white and bi-colors came later from the rampant mutation of tomatoes.  Larger sizes and pleated and odd shapes appeared, too. 

Tomatoes are promiscuous; their anthers extend beyond the flower, trapping pollen from other tomatoes grown within 100 feet.

Fuzzy, yellow Garden Peach tomatoes are genetically closer to the original wild tomato than are red ones.

Europeans didn’t embrace “poison apples”, as they called them until the invention of the pizza in 1880 by the Italians.  Royalty used lead trenchers for tableware, and the acid of tomatoes sucked up the lead and sickened or killed regal diners. Poor people used wood trenchers and ate tomatoes with abandon, as they were plentiful and cheap.

Tomatoes are easy to grow if you take care of their needs in advance.  Pests won't be a  problem either.

Tomato Tips

  • Plant the right tomato for your climate.  Determinate or bush types produce their entire crop in a few weeks.  They are perfect for short seasons.  Indeterminates, or plants that keep on growing and producing until a killing freeze, do well in hotter climates with long growing seasons.  Or plant both types.  You’ll have a large harvest in mid-summer from determinates and a smaller, but steady supply of indeterminate tomatoes until frost.
  • Don’t over-feed plants.  Tomatoes produce best with slow-release fertilizers that deliver small amounts of nutrients continually.  Fast-release fertilizers result in ten-foot plants and no tomatoes.
  • Mulch plants thickly with straw, shredded leaves or any other organic matter.  This keeps soil moisture even and prevents fungal spores, which spread diseases over plants, from splashing up from the soil on to plant foliage.
  • Blossom-end rot is caused by inconsistent soil moisture, not lack of calcium in the ground. There is usually plenty of it in most soils, but calcium depends on water to transport it to plant roots.  So, mulch heavily and deliver at least 1 inch of water to plants weekly.
  • Withhold water for 3 to 4 days before harvesting.  Tomatoes will be sweeter and more flavorful.
  • Don’t refrigerate tomatoes for the best flavor.  Pick the day you want to use them or harvest them slightly green, eating the tomatoes as they ripen.
  • When killing freezes threaten, pick all the green tomatoes.  Place them in a single layer in cardboard boxes and store in a warm, dry area.  Tomatoes will ripen within two to three months, lengthening your harvest.  Think home-grown tomatoes for Christmas!

Homegrown tomatoes make fast, tasty salads if you slice them thinly.  Use at least two colors for a salad any gourmet would love.

  • For an eye-catching gourmet salad, thinly slice three different colored tomatoes, arrange slices on a bed of leaf lettuce, strew with freshly sliced basil and crumbles of Feta cheese and drizzle with olive oil and wine vinegar.
