how to take care of tomato plants

There’s something truly special about walking into your garden and picking a sun-warmed, perfectly ripe tomato. That incredible flavor is a reward for the care you provide throughout the growing season. While tomatoes are popular garden residents, knowing the fundamentals of how to take care of tomato plants is the key to a healthy, productive harvest that far surpasses anything you can buy at the store.

The Ultimate Guide on How to Take Care of Tomato Plants

Success starts with strong roots. When planting, dig a deep hole and bury up to two-thirds of the stem. Tomatoes can develop roots all along their buried stems, which creates a larger, more robust root system to support the plant. If you’re growing in containers, choose a large pot—at least 5 gallons—with excellent drainage.

Mastering Water and Feeding

Consistent watering is your most critical daily task. Aim to water deeply at the base of the plant, keeping the leaves dry to prevent disease. The goal is soil that is moist like a wrung-out sponge, not soggy. A layer of mulch around the base helps retain that moisture. For feeding, use a balanced, slow-release fertilizer when you plant, and then switch to a fertilizer higher in phosphorus as flowers appear to encourage fruit production.

Supporting Your Growing Plants

Most tomato plants need support to keep their fruit off the ground. Install cages or stakes early on to avoid damaging the roots later. As the plant grows, gently tie the main stem to the support using soft ties. For larger varieties, you may need to prune away some of the “suckers”—the small shoots that grow in the crotch between the main stem and a branch—to help direct the plant’s energy into producing fruit.

Keeping an Eye Out for Pests

Keep a watchful eye on your plants. Check the undersides of leaves regularly for common pests like aphids or tomato hornworms, which you can often pick off by hand. If you notice yellowing leaves or black spots, remove them promptly to stop fungal diseases from spreading. Good air circulation, provided by proper spacing and pruning, is one of the best preventative measures you can take.

With these core practices in mind, you’re well on your way to a successful season. Paying close attention to your plants’ needs will be your greatest tool, allowing you to adjust your care and enjoy the incredible taste of homegrown tomatoes all summer long.
