The good news is tomato plants are resilient. Identifying the problem early limits damage and makes it easier to revive the plant. Even plants with evidence of dying roots can be rescued.
Plants may wilt badly when soils are dry, but will revive rapidly when they are watered. A thorough watering once a week during hot, dry weather should be sufficient. Apply water directly to the soil around the base of the plants with a garden or soaker hose.
Drooping Leaves
But it's not the only potential cause. As contradictory as it may seem, overwatering can also cause leaves to droop and wilt, just like underwatering can.
In the very least, a new central leader will emerge and become the new main stem. Tomatoes are notorious for producing lots of “sucker” stems throughout the season, so you can count on something taking over for the lost main stem. You just need to be patient while the new stem develops.
Is it possible to overcome tomato wilt? The answer to this is, if it's caused by an environmental factor – yes, you can recover your plant. However, if the plant is wilting because of a pathogen, it is unfortunately, almost always necessary to uproot and destroy the plant.
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.
Tomato plants recover quickly from overwatering, usually in one to two weeks with treatment. How often should you water tomatoes? In the garden, water tomato plants deeply at the soil level once a week or twice weekly during hot weather depending on rainfall.
Overwatering tomatoes can lead to yellow and spotted leaves, while underwatering results in wilt and diseased fruit.
Tomato plants can fully recover from overwatering if you take action as soon as you spot the signs. To save your tomato plant, remove it from the soil using a garden fork or trowel. Next, clear as much dirt away from the soil as possible, using your hands or running the root system under the faucet.
A tomato plant typically lives for one growing season (6-8 months) when grown outdoors, but when nurtured in ideal or controlled growing conditions indoors, tomato plants can survive between 2-5 years.
Tomatoes are considered perennials, and as long as they're protected from the frost, they can continue to grow.
Symptoms on leaves - curling & distortion
Symptoms: upward rolling of the leaves. This is a common occurrence in mid-summer and is associated with high temperatures and moisture stress. Some tomato varieties, including heavily pruned determinate-type varieties, are more prone to leaf roll.
To create a solution that prevents and treats disease, add a heaping tablespoon of baking soda, a teaspoon of vegetable oil, and a small amount of mild soap to a gallon of water and spray the tomato plants with this solution. This needs to be reapplied regularly to maintain its efficiency.
Some growers prefer to use a high-phosphorus fertilizer, indicated by a larger middle number. You can also keep things simple with a fertilizer especially formulated for tomatoes – usually with a ratio like 3-4-6 or 4-7-10. Most importantly, don't over-fertilize. Too little fertilizer is always better than too much.
It depends on why your plant is wilting. Different causes require different responses. If you've under watered your plant or have extremely low humidity, you can add water more and/or raise the humidity level around the plant. If you've overwatered, wait until the soil dries out before you water again.
Bacterial wilt disease is most commonly found on tomatoes, although other solanaceous plants such as potato, pepper, and eggplant also may be infected. The first symptom is a sudden and permanent wilting of the leaves, even when there is adequate soil moisture (Figure 18).
Tomatoes love the sunshine. A position in full sun (that means an average of at least eight hours a day) gives the best results in most areas, though if you're in a hot climate you can get away with dappled shade.
Diane Smith instructed: “Put it outside in the sunshine with a water container underneath and water it well. Also, start to feed it once a week with tomato feed or seaweed feed.” Cameron Christine suggested: “Give it a soak. Then let it drought before watering again.
Tomatoes can grow in a temperature range from 10 to 35°C but grow best between 20 and 30°C. In a heatwave plants will transpire more, blossoms won't open and pollen will be destroyed, leaves will curl and fruit will not set until temperatures drop.
Hot weather and “early blight” yellowing lower leaves have given my tomatoes a tough time in some years. Try saving stressed tomatoes from heat or early blight using shade, vermicompost tea, and removing blighted leaves.
