Prof. Samuel Fitzgerald, Ph.D.Bell peppers can thrive in pots or in the ground, depending on your preferences. Certainly, the available space, climate, and your personal goals will all factor into your final decision. Still, both growing methods can be successful if cared for properly. Growing in pots typically allows for mobility, but growing in the ground provides natural insulation. When cared for properly, both options can yield; it's simply a matter of choice.
Container Advantages
- Soil warms faster in spring extending growing season
- Easier pest and disease control with fresh potting mix
- Ideal for small spaces like balconies and patios
Ground Advantages
- Deeper root systems access more nutrients and water
- Natural soil insulation protects during temperature swings
- Better support for large indeterminate varieties
Shared Requirements
- Minimum 6 hours direct sunlight daily
- Soil temperatures above 65°F (18°C) for growth
- Consistent moisture without waterlogging
The specifics of the container can make or break your success. For each, use a bucket of at least 5 gallons. Ensure there are holes for drainage to prevent root rot. I like to mix perlite into my potting soil; potting soil gets wonderful aeration from this material. Place your containers in places with morning sun and afternoon shade in hot climates.
Plants that are grown in the ground need the soil to be considered and prepared. Before planting, have the soil tested and amended to achieve a pH range of 6.0 to 6.8. Work in a few inches of compost for nutrients and drainage. Space the plants 18-24 inches apart in raised beds or rows to prevent the spread of disease infestation while providing proper air drainage.
Soil Temperature: Container soil will warm faster than ground soil and likewise cool off more quickly, requiring mulch to help keep it all under control. You'll find that black plastic mulch will warm the soil in a ground garden, while straw matched with your straw hats keeps container soil from overheating on the really hot days.
Choose your variety according to your method. If using pots or containers, stick to compact types, such as Mini Chocolate. If you're growing in the ground, opt for varieties like Big Bertha. I vary it and develop both for comparison. Either way, you'll have some prize winners.
You can switch plants between methods if needed. Start your pepper plants in containers as early as you like and then transplant to the ground when it is time to harden them off. You can then reverse the process to overwinter your plants before frost. This method also enables you to effectively extend your growing season.
