Tips

The spiciest types of peppers require a long maturing period. But you can speed things up at the beginning of the season by soaking the seeds for approximately ten minutes before planting. It softens the seed cover and improves germination time.

Going after snails and slugs and the disposing of them can be an extremely satisfying exercise especially if those small pests have already discovered your peppers.

A powerful water hose will shortly remove aphids and other pests from adult plants. Be mindful not to soak or harm your peppers. This is not advisable for young seedlings. Crop rotation is also a really smart tactic in order to avoid these pests.

Flea beetles feast on the underneath fresh leaves. They leave tiny pits. Larvae survive originally in the soil and roots. It creates small damage. Ensure speedy germination and growth of your seedlings so that they thrive through this vulnerable stage immediately. Flea beetles appear in the middle of the day, and they do not wish to get wet. Giving them a noontime drizzle can overcome the obstacle.

Watering demands

Peppers require a lot of water. Keeping the soil constantly wet will suffice but when temperatures rise then you may need to water daily to help the plants cope with the heat. Ideally, apply at least an inch of water every four days. Just water the plants adequately all through their lifespan. Install watering systems only when needed.

Best soil conditions to grow pepper in a greenhouse

Peppers grow well in nutrient-rich soil with adequate calcium and phosphorus. The ideal soil pH should be between 6.0 and 7.0. The optimal soil temperature for efficient germination is 70°F or slightly more to break dormancy. You can put heat mats beneath the containers to aim the right soil temperature. Apply foliar feed when the plants start to bloom and again every ten days. In addition, apply fertilizer soon after the first fruit emerges. This will ensure you get larger fruits but remember that excessive fertilizer limits their ability to produce fruit.

Lighting and temperature

Peppers require consistent light with proper temperature control. Choose a spot in your greenhouse that gets at least six hours of direct sunlight every day.

The seedlings will thrive fully with a daytime temperature of 65°F to 70°F and 60°F to 65°F in the evening. Do your best to keep these temperatures in your greenhouse.
