To save a dying tomato plant, immediately adjust its care routine: prune off diseased or yellowed foliage, ensure it receives 6–8 hours of direct sunlight, and water consistently at the soil base rather than the leaves. If waterlogged, improve drainage immediately.
Yes, a tomato plant can absolutely come back to life. Even if it looks entirely dead, wilted, or has snapped in half, tomatoes are incredibly resilient and can recover if the root system is still healthy or if you propagate a new plant from the remaining stem.
Not enough calcium – Solution: Test your soil, apply lime and gypsum as needed. Planting before temperatures raise to ideal levels – Solution: Wait for the right planting time for your Hardiness Zone. Too much water or too little water – Solution: Water them evenly through the growing season.
Although it seems silly, this simple garden trick really works. The baking soda absorbs into the soil and lowers its acidity levels giving you tomatoes that are more sweet than tart.
Coffee grounds provide tomato plants with a mild nitrogen boost, improve soil drainage, and help deter pests like slugs and snails. However, to avoid compacting the soil or stunting growth, it is best to compost the grounds first rather than dumping fresh grounds directly around the base of the plant.
The absolute best homemade fertilizer for tomatoes is a balanced, nutrient-rich compost combined with organic matter like crushed eggshells (for calcium) and banana peels (for potassium). This combination prevents blossom-end rot and fuels heavy fruit production naturally.
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.
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.
Baking soda has several garden uses, including as a mild insect repellent and pH test aid, but it can be harmful if overused due to its salt content. It's not recommended for killing weeds or adjusting soil pH long-term, as it can damage plants and soil health by causing salt buildup.
To save sick tomato plants, immediately remove all infected leaves and dispose of them in the trash, not the compost. Disinfect your pruners with rubbing alcohol between cuts. Apply a Copper Fungicide to control the spread, and water strictly at the soil base to keep the foliage dry.
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.
A dying tomato plant often shows widespread wilting, yellowing leaves that start from the bottom and move up, or brown, spotted, and brittle foliage that does not recover after watering. Other signs include stunted growth, soft rot in the stems, or a total lack of new fruit.
To revive your dying indoor plant, trim dead leaves, repot with fresh soil, adjust lighting, and water properly.
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.
Dawn dish soap is generally not safe to use on plants as a regular pesticide or cleaner. While some gardeners use highly diluted mixtures for pest control, Dawn is a detergent rather than a true soap. It is heavily formulated to strip oils and can easily burn foliage or damage the plant's delicate immune system.
Apply baking soda to your tomato plants at two key stages: when tomatoes appear (about 1 inch in diameter), and again when they are half-grown. To protect your plants from fungal diseases, start spraying preventively in late spring when cool, wet weather sets in.
Baking soda (sodium bicarbonate) is highly alkaline and contains salts. Because of this, it is not a plant food and should only be used on plants that tolerate slightly alkaline soil or benefit from its antifungal properties.
Top Picks
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.
Cutting the top off a tomato plant stops vertical growth and forces the plant to redirect its energy into maturing existing fruit rather than producing new foliage. However, the exact outcome depends on whether it's done intentionally at the end of the growing season or by accident.
Hydrogen peroxide is often used on its own for spot treatments, but pairing it with dish soap expands its usefulness by allowing it to tackle oily residue at the same time. That balance is what makes the mixture feel more powerful than many single-purpose cleaners.
The best spray for your tomato plants depends on whether you are treating pests, preventing fungal diseases, or fertilizing. For an all-in-one organic option, try Bonide Captain Jack's Tomato & Vegetable Spray to control both insects and diseases.
