Selecting a Planting Site:

Choose a sunny spot with well-draining, fertile soil for optimal growth.
Shishito peppers thrive in areas with plenty of heat and light, making them ideal for gardens, raised beds, pots, or even as houseplants.

Spacing, Depth, and Support:

When transplanting seedlings, ensure they are spaced 12 to 18 inches apart in the garden or 24 to 36 inches apart in a raised bed.
Provide support for heavy fruit-bearing plants with short stakes to prevent toppling over.

Fertilize Shishito peppers every four to six weeks with compost or a balanced NPK fertilizer to promote healthy growth.

Temperature and Humidity:

Shishito peppers thrive in hot, sunny conditions with temperatures between 70 and 85 degrees Fahrenheit.
Maintain adequate humidity levels for indoor plants to support optimal growth.

Harvesting Your Shishito Peppers:

Harvest peppers when they reach 3 to 4 inches in length for the best flavor.
Pick peppers in the morning to retain moisture and flavor, twisting gently to remove them from the vine.
