Tomato plants are both hungry and thirsty, so they need plenty of moisture, warmth and nutrition. One way to keep them healthy and well watered is to provide mulch. Mulch from grass or wood can keep moisture in the ground and provide additional nutrition as it decomposes. Organic and inorganic mulch can also keep soil and water from splashing up onto tomato leaves and fruit and causing fungus or other diseases. Use your grass clippings as mulch for your tomatoes, as long as your grass hasn't been treated with a pesticide or other chemical. To mulch your tomatoes with grass mulch, follow a few easy steps.
Things You'll Need
- Tomato plants
- Mulch, organic and plastic
Clear the soil around your tomato plants. Only mulch tomatoes once they're well-established.
In a separate location, mix grass clippings, dead leaves and other plant material together. The more organic material you spread around your tomatoes, the more nutrition they'll get.
Spread your grass clippings and mulch around your tomato plants. Leave a circle 1 or 2 inches in diameter around the base of your plant.
Water well, both around the base of the tomato plants and over the mulch. The mulch will soak up and maintain the moisture for the tomato plants.
Tips & Warnings
- Add mulch in summer to maintain moisture in the soil, and in winter to keep the plants warm.
- Put plastic "mulch" down over the ground before you plant tomatoes to warm the ground for planting.
- Frost can kill or damage tomato plants.
- Don't use organic mulch on brand new tomato plants, as it will cool the soil before they've become established.
