Cherry Tomato

The highest-value crop you can grow in a pot. One bush-type cherry tomato in a 5-gallon container can give you a handful of fruit every day for ten weeks.

  • Pot size 5 gallons minimum
  • Soil depth 12 inches
  • Spacing 24 inches
  • Days to harvest 65

Cherry tomatoes are the crop that convinces people container gardening works. They are more forgiving than slicing tomatoes, they set fruit in heat that shuts down larger varieties, and a single plant gives you enough to eat fresh every day. The catch is size: cherry types are vigorous, so a 3-gallon pot will dry out mid-season and split fruit. Give them 5 gallons minimum and a stake from day one.

How to grow it

  • Use a determinate (bush) or compact indeterminate variety for containers — full-size vines reach 6 feet and need a cage.
  • Fill the pot with a mix that holds water: two parts potting mix, one part compost, plus a handful of slow-release organic fertilizer.
  • Bury the stem up to the first true leaves when you transplant. Tomatoes root along the buried stem and grow a stronger plant.
  • Water deeply every other day in summer. Blossom-end rot comes from uneven watering, not from a missing nutrient.
  • Feed every two weeks once the first flowers open. A high-potassium liquid feed keeps fruit coming.

What goes wrong

  • Blossom-end rot: dark leathery patch on the bottom of the fruit. Fix by stabilizing watering, not by adding calcium.
  • Early blight: yellow-brown spots with concentric rings on lower leaves. Remove affected leaves and mulch the surface so soil does not splash.
  • Hornworms: big green caterpillars that strip a branch overnight. Check plants in the evening and pick them off by hand.

Harvesting

Fruit starts ripening about 8–9 weeks after transplant and keeps coming until frost kills the plant.

  • Pick when fully colored and slightly soft — cherry tomatoes ripen off the vine poorly.
  • Harvest every two days. Leaving ripe fruit on the plant slows new fruit set.
  • Before the first frost, pull the whole plant and hang it upside down indoors to ripen the last green fruit.
