You might stop giving any additional nitrogen, and next year give them less N to start with.
If they are already very tall, and that vigorous, but have no flowers at all, maybe they already got more N than they really needed and are putting all their energy into covering the earth with leaves instead of making fruits and seeds.
Try taking a dish towel and beating them a bit- it simulates rough spring weather and makes them think they are dying- that might help and is worth a try.
How large is the pot they are in? Is it sitting on concrete? if not they might try rooting under the pot so dont move them.
I would like to know what the fernier ones are too! Also how long has it been since these tomatoes were transplanted? Not sure where Kensington, NY is but up until recently you probably had cooler nights than normal just as we have in NE Pa. So many things can play a role but I like the suggestion of the others that it may be too much nitrogen.
I think some tomatoes just take longer than others to produce flowers. I have 47 varieties this summer and there are still some that have not set flowers. They are in straw bales and were fed the same stuff as the rest of the tomatoes that are already blossoming. Several of them are potato leaf if that makes a difference. They certainly did not get more nitrogen than the rest. Time will tell!
Hi there everybody!
In no real order here are answers
-Kensington is in Brooklyn New York it is a neighborhood name.
_The Fernier Ones are volunteers/ winter survivors from last years crop of indeterminate
cherry tomatoes theat grea all over the place and produced more fruit than the me, my family the birds and the bugs could eat!
The others, BTW, are Wisconsin 55's I started from seed.
there could be some of this strain a neighbor gave me the produced standard size
tomatoes with a sort of point on the bottom they mostly filled out as they grew.
They are not in a pot. I have only fetilized recently one or tow times this season via
a foliar/rootmiracle grow thingy - the blue crystals that dissolve on water.
The first photo appears to be a weed. You don't list your zone in your info but I can figure out your location. I was late in planting, by a month, and am just now having tomatoes flower and set, including cherries. Don't do anything besides exercise patience.
Thanks for the link, Dream. Maypop, 1lisac, I am going to have another close look at those
I have a stack of allergies- pollen, mold, pet dander ( if I have never met your pet before- I have three cats and I'm fine with them)... also allergic to strong chemical smells and many pesticides.
I am in zone 7-A--I don't know why it does not say so.
We had a long cool Spring and a warm not hot early Summer. Mom's pansies are looking better than they have any right to look in July..
Did you compare the foliage in your 1st pic (top of thread) with that in some of the closeups from my links? Likewise, did you do similar [side by side] comparisons with marigold foliage? You can find pics of various types of marigolds (including foliage) in PlantFiles and also via google images; you can use these pics to compare with your pic to search for something identical.
I still say it's ragweed. I checked it against a number of different varieties of marigold foliage, and, while a few were close, none were identical - but ragweed foliage is identical.
Can you estimate the height of the fern-leaf foliage? In one of the 1st few posts (top of thread), you described the foliage as being very tall and straight with a single trunk. Most marigolds top out at 2-3ft, while annual ragweed grows to a height of 4-6ft, usually with a single trunk.
You could post some pics of your fern-leaf plant in the Plant ID Forum to see what the folks over there think it is. You will probably get an definitive ID over there. There are a number of people in that forum who specialize in plant related fields of study. If you decide to do this, that 1st pic attached to your initial post is a good one to post for ID along with another pic showing a side view of the plant (if you can get one).
Just wanted to add one more thing. While I still think it is ragweed, I could certainly be wrong. I'm an engineer and software developer with just enough plant knowledge to be dangerous, as this is not my area of expertise. In the Plant ID forum you will usually get 2 or more plant specialists who will 'duke it out', 'arguing' in scientific terms about things like whether the leaves are alternate vs opposite, compound vs simple, etc, etc, until they come to consensus as to what it is - either that or they will just all agree from the start. Either way, in most cases, you should get a definite answer fairly quickly over there.
As to your tomato plants, I agree with what has been said already. Switch to a low nitrogen fertilizer and then wait. They should bloom and set fruit soon. Approximately how tall are the tomato plants, and do you know roughly how long it has been since you transplanted them into the garden? I think you said you had been using the blue Miracle Grow that you mix with water. If it's the regular Miracle Grow, it's 10-10-10. It would be better to change to something with a lower 1st number (and/or higher 2nd number). I started my tomatoes with regular MG, but then switched to Miracle Grow bloom booster after the plants were about 2ft tall. I now have lots of blooms and some green tomatoes, so that worked. (Mine started to bloom after about a month in the ground.)
Mystery plants are about three feet tall. I pulled a bunch today that might have been shading the tomatoes.
The variety of marigolds I suspect is Nematocidal Marigolds, I tried searching on the plant files
and got way way too many responses to look though- I have got to get the Latin name from the
package if I can find it. BTW those marigolds got really really tall before they popped up small yellow flowers.
