Yes, you can stunt a tomato plant—either intentionally (like a bonsai) or accidentally through improper care. Because they grow incredibly fast and vigorously, keeping a tomato plant small requires consistent management of its environment.
In short, if tomato plants don't have enough water, they can't remain healthy and grow properly. The ideal irrigation schedule depends on lots of factors, including temperature, humidity, soil type, and plant size. In general, you should water your tomato plant at least a few times a week if no rain falls.
To do the Missouri pruning technique on suckers, pinch off the growing tip, leaving only the two lowest leaves. To help improve airflow and cut down on the chance of disease, remove the leaves along the bottom 12 inches of the stems of indeterminate tomato plants.
Yes, cold weather will stunt tomato plants. Temperatures below 50°F (10°C) disrupt their circadian rhythm and cause chilling injury, resulting in stunted growth, leaf curling, and poor fruit production.
Regardless of what you might read or see in nursery promotions, planting tomatoes in October or November is not a fruitful experience, literally. The night temperatures are too low for the flowers to set fruit. Tomatoes planted in August or early September will grow quickly in the warm soil, warm nights and long days.

Coffee grounds provide tomato plants with slow-release nitrogen for leafy growth, trace minerals like potassium and magnesium, and beneficial organic matter. They also help improve soil drainage and can slightly deter pests like slugs and snails.
Yes, tomatoes will survive 50-degree nights, but they won't thrive. The ideal night temperature is between 55°F and 85°F. Consistently dropping below 50°F can slow growth, restrict nutrient absorption, and stunt the plant's development.
Gardeners use baking soda around tomato plants primarily to prevent fungal diseases, deter pests, and potentially sweeten the fruit by adjusting soil acidity.
Gardeners bury an egg in the planting hole because it acts as an organic, slow-release fertilizer. As the egg decomposes, it releases essential nutrients like calcium, nitrogen, and phosphorus directly to the tomato roots, which helps build stronger stems and prevents blossom end rot.
To stop tomato plants from growing too tall, use the "topping" method: cut off the main growing tip of the plant about 30 to 40 days before your region's first expected fall frost, or when it reaches the top of your trellis or cage. This redirects energy into ripening existing fruit.
Encouraging the last few to ripen
The simplest is to bring them into a warm room and place them in a paper bag with a ripe banana or apple. Both release ethylene gas, which encourages ripening. Keep the bag loosely closed, check daily, and you'll often find the tomatoes take on full colour within a week.
Perennials (Peonies, Daylilies, and Iris): Cut back perennials that have finished blooming to tidy up the garden and reduce pest issues. For plants like peonies, remove foliage to prevent overwintering fungal spores. While some plants benefit from fall pruning, others are best left untouched until spring.
When growing tomatoes, avoid planting before the danger of frost has passed, as cold temperatures stunt growth. Do not plant shallowly; bury stems deep in the soil for stronger roots. Never water from above—wet leaves invite blight—and avoid over-fertilizing with nitrogen, which creates bushy leaves instead of fruit.
Tomato plants fruit from June until the first frosts, thriving in the warm, light conditions of summer. However, the ripening process slows down as the days become shorter, so fruit that develops from September may not ripen before the first frosts arrive. Tomatoes ripen most quickly in a warm, light environment.
To grow bigger tomatoes, maximize the fruit's size by pruning excess branches, restricting the plant to just one or two main stems, and plucking off early blossoms. This diverts the plant's energy into sizing up the remaining tomatoes rather than spreading resources across too many fruits.
Hydrogen peroxide can be highly beneficial for tomato plants if used correctly. It is a cheap, effective, and readily available remedy used to control fungal diseases, manage pests, and aerate waterlogged soil. However, because it is a strong oxidizer, using too much can damage your plants.
The best homemade tomato fertilizer is a nutrient-rich, liquid compost tea. It delivers a gentle, balanced boost of essential macronutrients (nitrogen, phosphorus, and potassium). To make it, steep a shovelful of aged manure or compost in a 5-gallon bucket of water for 24 hours, strain the liquid, and water your plants.
Never plant fennel, brassicas (like cabbage, broccoli, and kale), potatoes, or corn near tomatoes. These plants can stunt tomato growth, compete aggressively for nutrients, or spread devastating diseases and pests.
Yes, coffee grounds can help your tomatoes grow, but they must be used correctly. They provide a gentle boost of nitrogen to the soil, aid in moisture retention, and can help deter pests like slugs.
Tomato plants are tolerant to 35*, though some Russian varieties can withstand a lot colder temps than other varieties. But generally they'll die off first hard freeze. Leave in the garden until spring, then toss in the compost bin, or pull now if you choose to clean your garden up before winter.
Baking soda can sweeten tomatoes and deter pests, but must be used sparingly to avoid harming plants. A light sprinkle around the base wards off slugs, ants, and aphids, and a diluted spray mix helps prevent fungus.
Tomato plants love the nutrients these provide, but these amendments must be broken down first. Eggshells supply much-needed calcium (which prevents blossom end rot), and coffee grounds offer nitrogen. However, direct, chunky applications take too long to decompose to help your plants immediately.
Epsom salts (magnesium sulfate) provide magnesium and sulfur to tomato plants, which boosts chlorophyll production, aids nutrient absorption, and corrects leaf yellowing. It promotes bushier foliage, stronger cell walls, and can enhance fruit size and flavor.
