How are your tomato plants doing? You may be seeing abnormal signs in your tomato plant indicating something’s not quite right. Let’s see if we can troubleshoot a few common issues with tomatoes.
This is called blossom end rot and is relatively common for tomatoes. It’s caused by a calcium imbalance in the plant. Avoid this problem by maintaining consistent water to your tomato plant (not too much or too little water). To treat the black bottom problem and end the season with some good harvest, pick off the affected fruit (otherwise they’ll just take needed nutrients from the plant and future fruits) and stick to a consistent watering plan. By doing these two things your tomato plant will most likely correct itself. Also, note that you can still eat tomatoes with blossom end rot–just cut off the black part.
If your tomato plant develops spots on the leaves, this is a sign of fungal or bacterial diseases. Usually, these diseases start on the leaves closest to the ground. Remove leaves that have the disease (you can remove up to a third of a tomato plant’s leaves without harming the plant). To prevent disease, water the soil under the plant and not the leaves. Use mulch to cover the base of your tomato plant. Also, try not to plant your tomatoes in the same place within your garden every year. Note: Don’t can or eat tomato fruits that has been infected by disease and have spots.
If you have a big, green, bushy tomato plant with just a few flowers, check to see what variety of tomato you have and the estimated days to maturity. Some tomato plants simply take longer to develop blossoms and fruit. The most probable cause of little to no fruit development is too much fertilizer or too much nitrogen in the fertilizer. Check the NPK of the fertilizer you applied. The first number (nitrogen) should not be higher than the other two numbers; otherwise, you are telling your plant to grow leaves and not fruit. If you have been using a balanced fertilizer, your plant could be over-fertilized. Wait to fertilize until fruit appears and is growing. Be sure to also give your tomato plants consistent water. An inconsistent watering schedule could also be the cause of lots of leaves and not blossoms.
If you come out one day and notice a whole stem or section of your tomato plant is missing, a Tomato Hornworm is most likely the culprit. Tomato hornworms are giant green caterpillars with a horn on their tail. They are capable of eating leaves, entire stems, and the fruit of tomato plants. They can be devastating if not found. Tomato hornworms are excellent at camouflage and can be difficult to find. Manually removing them is the only real remedy to save your tomato plant. To make finding them easier, consider trying a blacklight at night. To prevent and kill these pests from taking over, consider treating your plants with neem oil (an organic home gardening solution).
If your tomato plant is drooping or sagging, this is most likely caused by a lack of water. As we’ve said previously, consistent watering is important to tomato plants. Tomatoes also don’t stand up if they are not getting enough sunlight, so make sure your tomatoes are planted in a sunny spot that gets at least 8 hours of direct sunlight per day.
Consistency is key—especially with watering and fertilizing. Keep an eye out for early signs of disease or pests, and act quickly. With the right care, your tomato plants can bounce back from most common issues and still produce a delicious harvest.

bloosems few if any tomatoes
A little long-winded explanation, tomatoes the most Gardened revered fruit or veg. around the world. Do any of you remember what a Tomato use to taste Like? I live in Platania, Crete a portion of the year and have watched the destruction of the Tomato (That New white core that has to be cut out) they have introduced the Roma with little results they lack taste. I usual plant in May with Plant purchased from a Nursery west of use ( I start with a Six pack) with fresh soil mixed with compost from the field cow mainour. I make my trellis’s from river bamboo laced with twin. I dust with copper sulfate green powder/My growth is Off the wall/ tomato’s being harvested by the first of Aug / alone with the Basil and Zucchini “Black” a seed product from the US. along with Mustard green something not seen in Crete one of my favorites.! I also plant in the Family field around the Platania River spinach. What I’m seeing around the world where tourism has been proliferated is the destruction of the Family Garden fields in my area alone, I’m one of the Last. my neighbor across the street still makes his Mizithra cheese each morning from Cows milk, but he no longer has a garden. he still tends to his grapes and olives. our Family still a Garden only tended by the father the usual goats/chicken and rabbits they serve in their restaurant.

And the other invisible anomalies Chornobyl Radiation. fallout. seasonal wind distribution exacerbated by the failed sarcophagus and fire .
My tomato plants are still less than 2 feet high with no fruit yet :( Zone 9, lots of sun, enough water, great drainage, hot weather…. three different varieties. I am so perplexed!
Hi! I didn’t know I shouldn’t eat tomatoes that had black spot on leaves…I have always done that…
