Tomato plants wont produce?
You don't say where you live, but nighttime temperatures need to be up to a certain temp for fruit set to occur.





If you live anywhere near me - the past few weeks have had nicely cool nights. Which is great for sleeping and not waking up sweating, but not so good for tomatoes setting fruit.





Because of the night temps around here, our first tomatoes are going to be a little later than in previous years. That might be the case in your area as well.
Reply:you say that the flowers bloom and die then fall off so I think it sounds like a pollination problem.





"Temperature is an important factor in the production of tomatoes, which are particularly sensitive to low night temperatures. Blossom drop can occur in early spring when daytime temperatures are warm, but night temperatures fall below 55 degrees F as well as in summer, when days are above 90 degrees F and nights above 76 degrees F."





Do you think this could be the problem?





If so, during the warmest part of the day, you can encourage pollination by tickling the blossoms.





If you are going to put fertilizer on your plants, make sure it is low nitrogen. Too much nitrojen encourages leaves instead of fruit.
Reply:If you live in the south (or any area where this would apply), hot windy weather can affect fruit set because it can cause more stress on your plants. I've had some luck with my tomatoes, but I've seen many flowers just shrivel or fall off. Make sure you keep them well watered, as the flowers will have a higher likelihood to shrivel and die if the soil is allowed to get very dry, especially under these circumstances.





You may also want to try fertilizing (if you aren't already doing so) when you notice the plant having several flowers as it is best to fertilize while the plant is flowering because it helps the fruit set. My tomato plants seem to flower in spurts, but if your plant is continually flowering and just not setting fruit, you would obviously just try this out with one watering (with water-soluable fertilizer) or a side dress, but it should not be something you have to do with a high frequency. I usually fertilize all of my plants every 2-3 weeks since I live in a climate that's a little harder on them. Good luck!
Reply:You might go to the local nursery and ask them. It sounds like there might be something eating on the plants or the blossoms. Look for little white spots or flys on the leaves. They suck the life right off of the plant. Tomato worms are reaking havoc on them too.


You might also look into tomato plant food stakes that can be stuck in the ground for added nutrients to boost the plant growth for production.


Place on the outer edge of the plant where rain or watering will drip down on them to release the food into the soil. Roots are only as far out in the ground as the branches of the plant.


Keep the new sucker growths pinched off to promote the food going back to the roots to make sure they bare fruits for you. Keep them well drained, but the roots moist. Tomatoes are shade plants, but do well in full sun if not too hot and humid in your area. Good luck!
Reply:This is called "blossom drop" which one thing contributes to it is when the temperatures also GET TOO HIGH..tomatoe plants will fruit in hot temperatures, but if indeterminate tomatoes when the temperatures begin reaching constantly in the 90 degree range, they start dropping thier blossoms..They recover and fruit again once the high temps get back down to 85 or so..There are other reasons as well for blossom drop..here is a link concerning this

Reply:Probably miscarriage. Get the tomato fruiting fertilizer. Make sure there are insects for pollination- bees, butterflies, etc., or you may have to do it yourself...
