Tips for Growing Peppers in Your San Diego Garden

May is an ideal time to plant peppers in your garden in San Diego, especially if you start from seedling plants. Here’s why: peppers need a good dose of warm weather to get started, and May is when the temperature begins to warm up in San Diego. In fact, when daytime temps hover at 75 to 85 degrees and between 50 and 60 degrees at night, peppers are happy.

Pepper Varieties to Grow in Your Garden

When considering which peppers to grow in San Diego, climate and growing conditions are essential. Most peppers that thrive in SoCal prefer plenty of sunshine and warmth, so May is a perfect time in San Diego County. So, which pepper varieties should you grow in your garden? 

The following are great pepper options for gardens in Vista, San Marcos, Rancho Bernardo, and throughout San Diego:

• Jalapeños
• Bell peppers 
• Anaheim peppers
• Serranos
• Poblanos
• Cayenne peppers
• Padron peppers

Of course, you’ll want to consider growing peppers that best suit your needs. If you prefer sweet peppers, bell peppers are right up your alley. Anaheim or Poblano peppers are ideal for those who love just a little bit of heat. And if you like your spicy heat turned up, consider growing Jalapeno, Serrano, Habanero, or Ghost peppers.

Growing Conditions for a Pepper Garden in San Diego

Sunlight: Plant peppers in a location that receives at least 6 to 8 hours of sunlight daily. Don't have in-ground space in your yard that gets this much daily sunlight? You can also grow peppers in a 2-gallon pot and place it on a sunny balcony or patio. If you plan to grow in a container, be sure it’s in a container with plenty of drainage and use nutrient-rich potting soil. 

Soil Requirements: Peppers will do well in well-drained, pH-neutral, sandy loam or a quality potting mix. They grow well with a steady supply of air, nutrients, and water. Peppers must grow in a location with proper drainage because if the roots sit in water, they can get waterlogged, leading to a host of fungal diseases. 

Water Requirements: Water peppers regularly and deeply. You’ll want to ensure that your peppers get consistent moisture, especially during hot and dry periods. However, do not overwater. Adding mulch, like wood chips, straws, or leaves, around the base of the plant will help conserve moisture. Mulching is also an excellent way to keep weeds at bay.

Fertilizer: When starting, mix in a reasonable amount of compost into the soil. While peppers need fertilizer, they don’t appreciate getting large doses of it. Too much fertilization can lead to excess foliage growth, which can hinder fruit production. 

Have a good Integrative Pest Management plan: Common pests include aphids, whiteflies, and spider mites. Also, make sure to give the plants plenty of space between plants so that they can get adequate airflow. 

Harvest when ripe: Once your peppers have reached the desired size and color, they are ready for harvest. Allow them to ripen to their final color for a more flavorful and sweeter pepper.
