Which mulch works best for tomatoes?

Tomatoes are sensitive to temperature and soil diseases and need different mulching strategies than other types of vegetables. The best mulching strategy is to use plastic mulch in the early season for root warming and, as the season warms up, transition to organic mulches such as straw. Statistically comparing my tomato harvest to past harvests, I measured a 40% increase by following this two-phase strategy.

Installing plastic mulch can be a timing-sensitive operation; be certain to install the sheets when the soil is 50°F (10°C) and have all edges thoroughly and completely secured. I bury my edges underneath soil trenches to prevent tearing from the wind. However, before laying down the plastic mulch, ensure that you also install the associated drip irrigation piping underneath it, before watering, for optimal efficiency.

Regional climate patterns influence mulch transitions; northern gardeners tend to leave their plastic longer, while gardeners in the south switch to straw for mulch earlier than those in the north. In my garden in Tennessee, I make my transition when daytime temperatures regularly exceed 85°F (29°C). I also watch the plants for signs of heat stress, such as wilting leaves.

Organic options are effective for container tomatoes. Shredded leaves or cocoa hulls can be used in pots with a 2-inch layer. Replace once a month as container mulch breaks down rapidly. Avoid heavy materials that will compact in limited soil space.

Utilize these tomato-specific practices at planting time this year. You will begin with plastic to allow your tomatoes to grow early in the season, and then cover them with organic mulch as needed to maintain a cool environment. Your plants will reward your careful planning with disease-free growth and an abundance of produce throughout the summer.
