My tomato flowers are dying. The plant itself has developed yellowing leaves at its base. No catepillars seen?

Well unless they haven't got enough sunlight or water (yes I know it's obvious and of course you haven't been keeping your tomatoes in a darkened callar with no water), your most likely causes are:-



(a) Lack of Nitrogen and/or Potassium - tomatoes are very demanding plants that require a lot of Nitrogen and Potassium. Use a proprietory tomato feed.



(b) A fungal infestation - most likely due to overwatering or excessively damp and humid conditions. Check that your tomatoes aren't drowning and look on the underside of the leaves for signs of fungus (whispy white "cobwebs")... but also see (c) below. There are anti-fungal treaments available from gardening shops.



(c) Any one of a number of pests - check the affected leaves under a magnifying glass (some of these critters are small!). If you see any bugs crawling around or what looks like miniature "cobwebs" then you have an infestation of some kind.



If you can identify the creatures you should be able to find a way of killing them - a gardening shop will supply the appropriate treatment. Just make sure that the poison you use is suitable for plants that you are gonna eat otherwise it won't just be the bugs that are poisoned. There are also a range of biological pest controls available nowdays (these are other bugs which feed on the bugs eating your tomatoes).



If you can't identify the bugs then I find that one good, cheap and harmless (as in harmless to the tomatoes and to me when I eat them!) cure is to spray the underside of the leaves with dilute washing-up detergent (preferably one that is bio-degradable). Spray late in the evening so the leaves don't get scorched by the sun - it kills the bugs stone dead.



And remove any dead leaves that have fallen off... they may contain more bugs (or their eggs) and so may cause re-infestation.

It sounds like either fusarium wilt or verticillium wilt the fusarium wilt is found in warm climates and the verticillium is found in cooler climates. This is a soil borne disease and there is no cure...sorry...

Reply:Probably too much water. If you are in the East, you got tons of rain. That much water is not good for tomato plants. Even if you are in a drier area, you may be overwatering.
Reply:First of all the obvious, is there enough sunlight? And of course water and oxygen? Next, you may want to re-root your plant and give it more room, if it's in a pot, and spray the leaves with water to make sure there is no dust present to block sunlight and oxygen from getting in. Good luck with your tomatoes.
Reply:GET SOME NEW POTTING SOIL FOR THEM AND DONT OVERWATER THEM THERE LEAFS USALY YELLOW FROM OVER WATERING
Reply:TOO MUCH WATER - make sure they are planted in well drained soil. even if you don't see water on the surface, it sounds like the roots are sitting in water. Less water and/or better drainage is the solution to your problem.
Reply:Are you watering too much?

Too much fertilizer?

Usually we love our plant to death
Reply:root fungus?



if not, try some miracleGrow, and sunlight. :)



it may also be that they are male flowers. the female flowers are the ones that produce the fruit..
Reply:Only water in the morning when the soil is dry (every other day should be enough). You don't want wet leaves at night. Go ahead and cut off the yellow leaves. Be sure to use a good fertilizer especially for tomatoes. It should take a few days, but you will see improvement.
