Possibly too much nitrogen. High N soil and use of high N fertilizers gets you nice big bushy plants but with no fruit.

Ok this might sound stupid but how do I change that, and what effect will this have on my other veggies in the same garden? Would it be wise next time to have one garden for tomato and another for my other stuff? Thanks for your help

Surprisingly, plants don't need as much nitrogen as we think. Unless the soil is very sandy you shouldn't experience a need for large doses of it. Too much and the plants weaken then aphids and whiteflies become attracted. Because a little is good it doesn't mean a lot is better. I've found that plenty of compost mixed in the soil seems to have all that is needed for most everything. Makes a good mulch too. Hope this helps.

are your tomatos in the garden or pots? I have about 40 flowers amid 8 tomato plants and I think it is from using fertilizer. I swear by Tomato Miracle Grow fertilizer. I use it everyother time I water. I would try that - it is about $5 at Wal-Mart or local nursery and that should boost your flower production - tomatoes require so much fertilizing - very heavy feeders in order to flower. I have a problem with wilting leaves right now - or drooping leaves, trying to figure that one out? Any help? Good Luck with your tomatoes.

I have them in a garden with many other veggies and herbs. They are all in the ground, and everyone of them is doing great but the tomato. I talked with my local garden guy here in Phoenix, he said that your dropping leaves may be caused by a couple of things he said that if water gets on the leaves during the heat of the day that will cause that to happen, he also said that tomato like deep water and if the roots start to dry because of not enough deep water they will also wilt. Hope that helps. I have been using fertilizer on my toms every week I use seaweed extract and fish emoltion. Not good enough??

Well, occasionally a plant will just not produce flowers at all. It's got to be some kind of genetic problem that apparently has no evident cause. At this time I've got two identical plants, side by side, with tomatoes on one and nothing but leaves on the other. Not one flower has formed on that darned plant. It just happens and I wish there were an answer to give you that would help.

Hi LITS,

I suspect that you probably do have a nitrogen balance that is too high. It is a pretty common problem when gardeners feed their tomatoes. They tend to think that the higher nitrogen will help them grow tomato plants, and it will! But the high nitrogen will cause the tomato to make loads of leaves at the expense of blossoms. No blossoms means no tomatoes.

What is the balance (NPK) of the fertilizers you have been using? Feeding weekly just sounds like too much for plants that are in the ground. (Container plants are different in their needs.) I find that directions on bottles and those that you get from sales people are often oriented towards selling more fertilizer. . . .

Jbann,

Your issue with one plant having fruit on it and the other not having any might be genetic, but likely for a different reason than you think.

What varieties are the two plants you have? If the one that has tomatoes is an early variety and the other a late variety, that would certainly explain what you are seeing.

OTOH, if they are the same, I would look for environmental differences. My mother has for many years planted two tomato plants every year, one at each end of her front porch. Both are sheltered, but one is against a north facing wall and the other a south facing wall and the one by the south facing wall always grows larger, produces sooner and more than the other.

Is one closer to a sidewalk where the ground may be more compacted? Is one in a corner where it may have a concrete footing to contend with on two sides while the other is affected by only one? Does one get more shade or sun than the other? There are literally hundreds of reasons why one plant will perform differently from another.

Are you in Phoenix? Triple digit temps might cause them to not flower much. Just a thought.

^^^^^^ This

It also causes those blossems that do form to drop very quickly.
