Planting cucumbers in pots can yield excellent results. The bush varieties, such as 'Spacemaster', produce heavily in 5-7 gallon pots with drainage holes. Potting on to a good-quality potting mixture and regular watering are essential, and a sunny spot with most of the day's sunlight is ideal. Container gardening enables the growth of cucumbers even in small urban spaces.

Container Specifications

  • 5-7 gallon capacity with drainage holes
  • Light-colored pots prevent root overheating
  • Elevate containers for airflow underneath

Soil and Nutrition

  • Mix: 70% potting soil + 30% compost
  • Apply balanced fertilizer weekly during fruiting
  • Maintain pH 6.0-6.8 with test kits

Water Management

  • Water deeply every morning above 85°F
  • Check moisture twice daily in heat
  • Use self-watering pots for consistency

"Provide" structural support even for compact varieties. Set out small trellises or cages at planting time to encourage them to grow upright, allowing them to receive more air and decreasing the chances of disease. Secure them gently with soft ties to help them grow stronger. "Upright" growth is the most efficient use of any limited space.

Microclimate management: You have pots of containerized plants. Manage their exposure. Rotate them so all get equal sun; use light-colored pots to reflect light (heat) from all summer long. Move them under breezy eaves in a windstorm or with torrential rains.Save the plants and get another flush of flowering. It numbers in thousands of blossoms.

Pick container cucumbers at peak ripeness for the best flavor. Harvest the fruit every couple of days when they reach variety size. Cut them from the vine with sharp scissors to avoid damaging the vine. Regular harvesting encourages continual production.

Container plants can be overwintered where the climate permits, provided the pots are moved indoors before the first frost. Supplemental lighting during the shorter days may be required, along with less frequent watering during their dormant state, thus extending the growing season and increasing crops from the same plant.
