Growing Instructions

Starting your seeds

You can start pepper seeds indoors using a heat mat to encourage germination. Once the seedlings sprout and grow a few sets of leaves, move them outdoors. Keep the soil moist but not soggy, and provide 6–8 hours of sunlight daily. When direct sowing pepper seeds, plant them about 1/4 inch deep with a light cover of soil in well-drained, warm soil. Space plants 12–18 inches apart to allow for healthy growth.

Harvesting your seeds

To harvest peppers wait when they reach the desired size and color. Use sharp scissors or pruning shears to cut the peppers from the plant, leaving a short stem attached. Avoid pulling or twisting the peppers to prevent damage to the plant. Harvest regularly to encourage more fruit production.
