It has been found that living mulch and organic mulch fabrics are far better at preserving the favorable soil temperature compared to other mulch materials (Walsh et al. 1996). Adequate moisture levels promote healthy plant growth and prevent issues like blossom end rot.

Temperature Regulation:

Mulch helps regulate soil temperature by insulating it from extreme fluctuations. Chili peppers are sensitive to temperature changes, and a stable soil temperature can promote better root development and overall plant health.

Weed Suppression:

Weeds can compete with chili pepper plants for nutrients, water, and sunlight. Mulch effectively suppresses weed growth by blocking sunlight and preventing weed seeds from germinating. This reduces the need for manual weeding and ensures that chili peppers receive the resources they require.

Disease Prevention:

Mulch acts as a barrier between the soil and the chili pepper plants, minimizing the splashing of soil-borne pathogens onto the foliage. This can help prevent diseases that might otherwise harm your chili peppers. It helps in the nutrition of many beneficial beings which competes with the incoming pathogenic spores or sometimes releases chemicals for the prohibition of pathogens; in this way, they reduce the chances of disease (Chalker-Scott 2007).

Soil Improvement:

Over time, organic mulches like compost or shredded leaves break down and enrich the soil with valuable nutrients. This can enhance the long-term health and productivity of your chili pepper plants. It is observed that organic mulches are more helpful for the reformation of soil and induce the desalinization of soil (Dong et al. 1996).

Types of Mulches for Chili Peppers

Mulches can be broadly categorized into two main types: organic and inorganic. Each category presents distinct advantages and disadvantages, underscoring the importance of selecting the most suitable mulch for your particular requirements and the specific chili pepper variety you’re cultivating.

Organic Mulches:

Naturally, organic mulches are made from natural(organic) materials that disintegrate over time, adding the soil with nutrients and beneficiary elements. Some of the common organic mulches suitable for chili peppers are as follows:

Straw:

Straw is the most affordable component for mulch and is easy to apply. This lightweight element offers excellent moisture retention. However, it may also serve as a refuge for pests, necessitating vigilant monitoring for any potential infestations.

Grass Clippings: 

Grass clippings, easily accessible and rich in nitrogen, can serve as a valuable nitrogen source for your chili plants. Nevertheless, when applied excessively, they have the potential to create a compact layer that inhibits water infiltration into the soil. To avoid this issue, ensure you spread them thinly and let them dry before applying them to your garden.

Leaves: 

Dropped leaves help for an excellent, cost-effective mulching solution. It not only enriches the soil as it breaks down but also exhibits effective moisture retention. To prevent the leaves from compacting and obstructing water penetration, it’s advisable to shred them before applying them as mulch.

Wood Chips or Bark: 

Wood chips or bark represent important elements, durable mulch options that excel in both insulation and weed control. Nonetheless, during their decomposition process, they can temporarily diminish soil nitrogen levels. To counter this effect, consider supplementing with a nitrogen-rich fertilizer as needed.

Compost: 

Compost is also a superb component for mulching, enriching the soil with essential nutrients as it decomposes. Its presence can contribute to enhancing soil texture and fertility, fostering robust growth in your chili plants.

Cocoa Bean Hulls: 

Cocoa bean hulls, a byproduct of chocolate manufacturing, are excellent and nutrient-rich elements for making mulching as an alternative element. It’s worth noting, though, that it may come at a higher cost compared to alternative choices, and it has the potential to attract pests such as slugs.

Inorganic Mulches:

Inorganic mulches are materials used to cover the soil in gardening and landscaping that are not derived from living organisms. These mulches are typically made from non-living substances such as plastic, rubber, or stone. Inorganic mulches do not decompose over time, making them long-lasting and low-maintenance options.

It is effective at weed suppression and moisture retention but does not contribute organic matter or nutrients to the soil. Some common examples of inorganic mulches include landscape fabric, gravel, and rubber mulch includes. 

Plastic Mulch: 

Plastic mulch excels in weed control and temperature regulation, making it a favored option for cultivating chili peppers in containers or greenhouses. Nevertheless, it hinders water infiltration and gas exchange, and its environmental impact can be less favorable.
