To grow a bumper crop of tomatoes, plant seedlings deeply—burying two-thirds of the stem to build a massive root system. Provide 6-8 hours of direct sun daily, water consistently at the base to prevent blight, and apply a balanced fertilizer throughout the season.
Devote a prime, sunny spot to growing tomatoes. Tomatoes need at least 6 to 8 hours of sun to bring out their best flavors. You will need to stake, trellis, or cage most tomato plants to keep them off the ground. Decide on a support plan before you set out your plants, then add that support directly after planting.
Top Picks
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.
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.
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.
You should grow only one tomato plant per 5-gallon bucket. Tomatoes have extensive root systems and heavy nutrient requirements; crowding them limits your yield and increases the risk of disease.
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.
Tomatoes benefit from the nutrients in eggshells and coffee grounds, but the way you use them matters.
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.
I'm sure you have heard the old saying that snow is “poor man's fertilizer.” The saying comes from the idea that snow storms deliver small but meaningful nutrients to the soil and there is real science behind that. As snowflakes fall, they collect nitrogen and ammonium and release them during the melt.
The best option is Miracle-Gro Water Soluble Tomato Plant Food. Formulated with a balanced 𝑁−𝑃−𝐾 ratio of 18−18−21 plus added magnesium, it instantly feeds plants to encourage quick growth and higher tomato yields.
Wrong: Although tomatoes are heavy feeders, fertilizing the crop too much can be fatal. Especially when the seedlings are still very small! Too much nitrogen means that the plant has to put more energy into leaf growth - but the fruits fall by the wayside. They suddenly ripen much more slowly and have less flavor.
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.
Allow lots of space.
They'll get huge in the rich soil you'll be providing. Crowded plants will be more susceptible to diseases like blight and allow less light to get to the fruits. In my tomato-pot garden, for example, I only ever plant 1 tomato plant per large (24″ or greater diameter) pot.
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.
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.
Myth #1 — Epsom Salt is the best organic fertilizer
Epsom salt is neither the best nor an organic fertilizer. Organic fertilizers contain more nutrients and are better than Epsom salt for fertilization purposes.
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.
Nitrogen helps produce green leaves and stems, phosphorus helps produce root development, and potassium helps the plant withstand stress from heat or cold. A good all-purpose fertilizer would be a 10-10-10 NPK (nitrogen, phosphorus, and potassium). This type of fertilizer will work well for most plants and soil types.
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.
Water correctly: Do not overwater. The first week tomato plants are in the ground, they need water every day, but back off watering after the first week, slowly weaning the plants down to 1 to 1.5 inches of water per week.
1 (maybe 2 if done right) tomatoes per 5-gallon pot. keep in mind that tomatoes in the same container will become inseparable because of the roots growing into each other.
