10 Reasons to Consider Chili Peppers Greenhouse Growing

Chili Peppers Greenhouse Benefit #1: Controlled microclimate

Because chili peppers are plants from warmer regions, they require higher temperatures for growth and development (especially for seedling production). That’s why growing chili peppers in a greenhouse is advised.

Peppers greenhouses can have heating systems installed, so temperature control in such enclosed spaces won’t be an issue. However, during hot summer days, peppers greenhouse cultivation can be risky due to excessively high temperatures.

To avoid “cooking” the plants, peppers greenhouses are ventilated by opening both front (door) or side panels. Additionally, peppers greenhouses can be “cooled” using a fog system that sprays water in the form of fine droplets resembling mist, increasing relative humidity and lowering the temperature.

Chili Peppers Greenhouse Benefit #2: Natural Disaster Protection

A greenhouse provides good protection against natural disasters such as hail, strong winds, heavy rain, and frost, which pose significant threats to your chili peppers.

A greenhouse is essentially a roofed house for plants. By closing it, you create a higher temperature compared to the external environment, so in case of frost, your plants won’t be harmed.

Plants might be affected only along the sides of the greenhouse if it’s not properly sealed.

Chili Peppers Greenhouse Benefit #3: Earlier Harvest

With greenhouse cultivation, you can start planting chili peppers as early as the second half of April. Outdoor planting doesn’t begin before May 1st due to the risk of frost, which can damage newly planted young plants.

Hot tip: Prepare the soil for greenhouse pepper planting at least 2 weeks before to allow the soil to warm up. (When I mentioned soil preparation, I meant: soil cultivation using a tiller or hoe, setting up irrigation systems, forming beds, covering beds with black plastic, and drilling holes for seedlings).

Chili Peppers Greenhouse Benefit #4: Targeted Irrigation

Targeted irrigation or watering of chili peppers should be done at the soil level, around the root zone and the root collar. Watering chili peppers over the foliage increases the risk of developing fungal leaf diseases.

That’s why the most common irrigation system used in greenhouses for chili peppers is drip irrigation. With this irrigation method, water is delivered directly to the targeted area through drip lines.

The water is evenly warmed through black pipes, preventing any shock from cold water during hot summer days. Additionally, this irrigation method conserves water, as it doesn’t evaporate quickly after application.

Through this system, most fertilizers or plant protection products can be applied along with water.

Chili Peppers Greenhouse Benefit #5: Easier Pest Monitoring

Yellow sticky traps (for aphids) and blue sticky traps (for thrips or whiteflies) are commonly used for pest monitoring in greenhouse pepper cultivation. These traps attract pests of the respective colors. Visual inspection of these traps can be done weekly to monitor pest activity in your greenhouse 😊

Regarding pest monitoring, I will explain what the critical threshold of pests means in plant protection. Understanding this concept is crucial in modern agriculture, where efforts are made to reduce pesticide use.

The critical threshold is defined for each pest individually, and if it is exceeded, the economic and ecological justification for pesticide application exists. I’ll explain this with an example of aphids: if you find more than 100 aphids on 25 pepper plants in your greenhouse, the application of insecticide is justified.

If there are fewer than 100 aphids, the cost of the insecticide you’ll use to spray them will exceed the economic damage caused by the aphids.

Chili Peppers Greenhouse Benefit #6: Simplified maintenance and introduction of natural enemies

Ecological farming practices are increasingly popular today. If you encounter specific pests on your peppers in the greenhouse (I’ll simplify and refer to aphids again), instead of using conventional insecticide, you can introduce ladybugs, both larvae and adult individuals, as natural enemies of aphids.

Commercially available natural enemies for certain pests can be introduced into greenhouses. In outdoor cultivation, such biological control is not as straightforward as in greenhouses because these insects cannot be restricted to a specific area.

Once you introduce natural enemies into the greenhouse, they have abundant food and continue to reproduce, maintaining the pest population at a minimum level.

Chili Peppers Greenhouse Benefit #7: Longer Vegetation Period – Higher Yield

As mentioned earlier, chili peppers can be planted in greenhouses two weeks earlier than outdoors.

If planted earlier, they logically have a longer growing season and will yield fruit sooner.

Also, due to protection from external hazards and low temperatures, your chili peppers can live longer than those grown outdoors.

Chili Peppers Greenhouse Benefit #8: Less Weeding

In peppers greenhouses you will notice reduced competition between weeds and peppers. Planting peppers in a greenhouse is often done in raised beds covered with black plastic mulch, beneath which irrigation pipes are placed.

If you plant them this way, you’ll have less work with weeding or mowing weeds. Weeds can harm peppers by competing for water, nutrients, and space above and below the soil.

By covering the soil with black plastic mulch, you not only maintain soil temperature and moisture but also prevent or reduce weed growth. This allows your chili peppers to grow undisturbed, and you’ll have to do less weeding 😉

Chili Peppers Greenhouse Benefit #9: The Peppers Greenhouse Serves as Semi-permanent Protected Space

After the chili pepper season is over, the peppers greenhouse doesn’t have to remain empty and wait for the next spring to grow peppers again. Utilize it for growing spinach, lettuce, arugula, and similar vegetables.

Chili Peppers Greenhouse Benefit #10: You’ll Be The Envy of The Town

This doesn’t need much explanation. Many will envy your peppers greenhouse, especially if they peek inside and see the spicy beasts in full yield. 😀
