Why Put Something Red Under Tomato Plants?

Tomatoes are one of the most popular vegetables to grow in a garden. They are easy to cultivate, produce bountiful harvests, and are extremely versatile in the kitchen. Gardeners often go to great lengths to provide their tomato plants with the best conditions possible, including proper soil, water, and sunlight. However, one thing many gardeners overlook is placing something red under their tomato plants. In this article, we will explore the reasons behind this gardening practice.

The Science Behind Red

Red is a color that is highly attractive to many insects, including the tomato hornworm. These pests can cause significant damage to tomato plants by eating their leaves and fruit. However, by placing something red under tomato plants, such as a red plastic mulch, these pests can be deterred from attacking. The reason for this is that the color red appears to these insects as a warning signal, indicating danger or an unappetizing food source.

Increase Tomato Yield

Not only does the use of red mulch protect tomato plants from pests, but it can also increase their yield. A study conducted by researchers at Cornell University found that tomato plants grown with a red plastic mulch produced significantly larger yields than plants grown without. This is because the red color reflects more red light onto the tomato plants, stimulating their growth and photosynthesis.

Alternative Red Materials

If you don't have access to red plastic mulch, there are alternative materials you can use under your tomato plants. Red landscaping fabric or a layer of red newspapers can provide the same benefits as the plastic mulch. Some gardeners even paint rocks or bricks red to place under their tomato plants.

Other Benefits of Mulch

Mulch, whether it be red or not, provides numerous benefits to tomato plants. It helps to retain moisture in the soil, regulate temperature, and prevent the growth of weeds. Organic mulches, such as straw, leaves, or grass clippings, can also enrich the soil as they decompose.

Conclusion

In conclusion, placing something red under tomato plants can help protect them from pests and increase their yield. Whether you choose to use red plastic mulch, red landscaping fabric, or other materials, adding a layer of red to your garden can be beneficial to your tomato plants. Don't forget about the countless other benefits of mulch, regardless of its color. Happy gardening!
