Capsicums, also known as bell peppers, are a common plant grown in greenhouses for their sweet and colorful fruits. Proper spacing is crucial for plants to grow vigorously and produce a bountiful harvest. Planting distance of capsicum in a greenhouse can be either in the ground or in containers, and the spacing varies based on the type of capsicum, the size of the container, and growth habits of the plant.
Spacing for Ground Planting:
When planting capsicums in the ground, it is necessary to consider the mature size of each plant. For standard bell pepper varieties, a spacing of 18-24 inches is ideal. On the other hand, miniature pepper varieties like cherry peppers require a spacing of 12 inches. The spacing allows the plants to have enough room for their roots to spread out and absorb nutrients and water effectively. It also helps to prevent overcrowding that may cause plants to compete for light, water, and nutrients. Rows should be spaced between 24-28 inches apart, allowing for easy access for maintenance like weeding, pruning, and harvesting.
Spacing for Container Planting:
Alternatively, capsicum can be planted in containers. Containers provide better control over soil nutrients, moisture, and temperature, and they also save space and make it easier to move plants around for optimal sunlight exposure. The size of the container should suit the plant variety, with small containers for smaller peppers and larger ones for larger varieties.
Bell peppers do well in containers with a minimum size of 8-10 inches in diameter and depth. Miniature peppers, like hot peppers, can thrive in containers as small as 6 inches in diameter. The spacing between plants in containers is generally the same as in-ground spacing, with 18-24 inches between bell peppers and 12 inches for smaller varieties. Containers can be placed on shelves or elevated platforms, allowing plants to receive enough sunlight and fresh air.
In addition to spacing, greenhouse-grown capsicums need proper care and maintenance for optimal growth and productivity. This includes adequate light, water, and nutrients, balanced pH levels, pest and disease control, pruning, and regular harvesting. Providing the right planting distance for capsicum in greenhouses is a crucial aspect of maximizing yield and producing high-quality capsicums.
