To get your tomato plants to grow taller, choose indeterminate varieties (which vine continuously), train them to a single main stem by pinching off side "suckers," and provide a tall, sturdy trellis or stake. Feed them a nitrogen-rich fertilizer and water them deeply to support rapid, healthy upward growth.
If your tomato plant isn’t getting taller, it is likely dealing with a hidden stressor or is simply a specific variety that isn't meant to grow very high. Start troubleshooting by checking your plant’s label to determine if it is "determinate" (naturally stops growing at 3–4 feet) or "indeterminate" (keeps growing all season).
Baking soda (sodium bicarbonate) is used to control fungal diseases, deter pests, and slightly reduce soil acidity. However, it must be applied with caution; overuse can cause dangerous salt buildup and damage plant tissue.
The best method, however, is to support the plants from above. Our simple trellis, made out of galvanized electrical metallic tubing, is composed of support posts that hold up a top bar. We tie lengths of soft garden twine from the bar and train the tomato plants to climb them.
Coffee grounds can help tomatoes grow by providing a slow-release source of nitrogen and slightly increasing soil acidity, which tomatoes love. However, they should be used in moderation; too many fresh grounds can compact the soil, block water, and stunt growth.
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.
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.
To revive stunted tomato plants, first determine the cause: temperature stress, root-binding, nutrient deficiency, or disease. Apply a balanced liquid fertilizer, loosen compacted soil, and bury leggy stems deeply in fresh compost. For unrecoverable plants, start fresh with new seedlings.
Growing healthy tomatoes comes down to providing consistent care, adequate space, and proper sunlight. The most common mistakes include planting too early while soil is cold, overhead watering (which causes blight), neglecting to use plant supports, and planting in the same spot year after year.
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.
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.
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.
Yes, you can sprinkle baking soda on your plants, but you must do it very carefully. Because baking soda is a type of salt, using too much can draw moisture from the roots, raise the soil pH to harmful levels, and burn leaves if applied in direct sunlight.
Tomato plants that grow tall are known as indeterminate varieties. Unlike bush (determinate) tomatoes that stop growing at a specific height, indeterminates continuously grow, flower, and produce fruit all season long, easily reaching heights of 666 to 20+ feet depending on your support system.
As we move into the cooler nights and shorter days of October and November the fruit will already have been set. These “fall” tomatoes will develop and ripen slowly compared to your spring plants, but you will be rewarded with a nice crop of fresh, well-flavored tomatoes, perfect for your fall salads.

The secret to growing thriving tomatoes boils down to one major hack: bury the stem deeply when planting and feed them generously. Tomatoes form roots all along their stems, meaning a deeper burial creates a massive root system, which yields healthier, more resilient plants that can soak up the water and nutrients required to produce abundant fruit.
For many, it's best to avoid pruning in the fall because it can stimulate new growth that will be damaged by cold. On the other hand, there are a few plants to prune in October, especially if you want to keep your garden looking gorgeous right through to spring.
Tomatoes are hungry plants. They need a nutrient-rich environment to thrive. Poor soil nutrition can seriously stunt your plants and affect tomato development. Even if your seedlings look healthy initially, when they are planted out into depleted soil, they may stop growing or produce very few tomatoes.
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.
Baking soda (sodium bicarbonate) is used to control fungal diseases, deter pests, and slightly reduce soil acidity. However, it must be applied with caution; overuse can cause dangerous salt buildup and damage plant tissue.
To help tomato plants grow, apply a balanced, nutrient-rich vegetable or tomato fertilizer, mulch to prevent soil-borne diseases, and a calcium source like bone meal to prevent blossom end rot.
Epsom salt is not actually salt, it is magnesium and great for tomatoes, which love it. It will give you healthier plants and sweeter tomatoes. Add one tablespoon per gallon of warm water to help it dissolve. You only want to use it about once in awhile though.
Magnesium deficiency in tomato plants presents as interveinal chlorosis on older foliage (yellowing between the veins) while the main veins and surrounding tissue remain green. Because magnesium is highly mobile, the plant redirects it to support new growth, meaning younger, upper leaves remain green while mature, lower leaves discolor.
