16,949 Garden Web Discussions | Growing Tomatoes


I read a post once on one of the Gardenweb forums by someone in the Arizona desert who planted Fourth of July hybrid for spring harvest, cut it back almost to the ground when the weather got brutal (for tomatoes) and let it re-grow for a fall crop. I think it may have been in afternoon shade. This is a very early little tomato, barely slicing size, on an indeterminate plant. Has some disease resistance.
Fourth of July has tough skin and sometimes splits, but in our climate, it can get very sweet when the weather starts to heat up enough to make many other varieties less-than-wonderful.

Almost impossible to say without at least a photo and much more info. Is this a container plant? How large a container? What variety is it? How old is it? Determinate or indeterminate? Is Edna's Best Potting Soil actual soil/dirt or is it a soil-less mix such as normally used in containers? If it is soil then that alone could be your problem. Fed it once? Container plants require regular weekly feedings. Water only when the soil is very dry but container plants require consistent soil moisture levels, not alternate wet and dry.
Leaf activity such as you describe is often a response to stress of some kind. What is causing the stress could be any of the above.
More info please.

Sketch info as Dave said. I don't want to second guess
(sort of) Dave's comments, but I'd suspect not enough
water. It's also the quickest and easiest to fix.
If you'd post a photo would be most helpful.
It might just only be wilted. I'd slop some water on it
(and wet the leaves too) and see what happens. If it's
what I suspect, you will see improvement in a few hours
or faster.

Apparently few here have used it.
I looked it up and it says it is 5 feet wide, right? So if you are growing determinates it could start at ground level, if indeterminates then raise it up a foot off the ground like those who use cattle panels do so you end up with 5-6 feet in height over all.
How close? As close as possible. Netting is going to be so flexible that support would be flimsy unless the plants are practically on top of it. Once they develop some size and have the weight of fruit on them it will sag a great deal unless you really have some good tension on it.
Dave

simple answer. NO.
120 degrees is harmless to seedlings so long as they have plenty of water. I routinely let my greenhouse get up to 120 degrees in early spring to encourage rapid growth. It also helps out with ensuring the plants can survive when planted outside in the garden.
DarJones

Stressful for them but no long term effect. But it's of no benefit either so I'm curious as to why the air circulation can't be improved in your hoop house? How long before you can plant them or remove the hoop house and provide more normal conditions?

My plants have been out since May 1st... Our temps went to about 49 last night, but it was only that cold for a very short duration of the night. Most nights have been mid-50s and most for the future appear to be the same. The highs have all been around the mid 70s and all my plants are doing very well.
It's all about the length of the cold exposure, in my experience. If the daytime highs are going to be 65-75 and it drops to around 48 for a couple hours on the nighttime low, it's not that big of a deal - not ideal, but not a deal breaker. The weather has been so wacky that if I were to wait until I were _sure_ of nighttime temps in the mid-50s, I wouldn't be able to plant out till June... And, at that rate, my late season tomatoes wouldn't get to produce much before they were killed by frost in October. It's one of the struggles of growing tomatoes in the NE.
That being said, at least for SE PA, after tomorrow night, there are no more nighttime lows below 55 showing up in the extended forecast... If you look ahead for your area, it might be better conditions on Sunday; You've waited this long, for one day it might be worth the wait.


I went to the nursery today and I bought 12 more tomato plants. Planned on buying a six pack of BIG BOY tomatoes and doing a row of six in the Florida Weave style. Well, I did buy the six pack of BIG BOYS but I have no will power. I swear I would buy every type of tomato plant in the nursery if I had room. So I saw these lovely single plants of SUN GOLD and CHEROKEE PURPLE, bought those. So my row of six idea was changed to two rows of 4 idea instead! Then bought a Siberian tomato I will plant between two others already planted here by the house. And I found this patio garden growbag that is 39 inches long so I will put the last three (two FOURTH OF JULY and one SUGERY ) in there.
I had to buy bagged compost as I will be using to set up the new tomato garden area.

My neighbor grows nothing but celebrity around 90 or so every year. His get over 6' tall and are quite bushy. This year it seems as though we are locked in a tomato war. He has over 100 and I just discovered he has a secret little garden where he has at least another twenty or so plants (not bad for an 85 yo man. He has a ways to go though as I have 150 plants in the ground....I NEVER INTENDED TO HAVE SO MANY....thats my story and I'm sticking to it..... I have to go now and make some more tomato cages....LOL


Not trying to be difficult Dave.
I just always heard trenching is shallow,offers a nice head start in my cold clammy clay soil as the upper layers warm up sooner but requires more watering later on when the dog days show up.
On the other side, I've heard planting deeply means a slower start but shines when the hot, dry days come.
I've often wondered if planting leggy seedlings diagonally would offer the best of both worlds.

adc e-mailed me from GW this AM and asked me what journals I read about tomato diseases, etc., so I'll answer here.
The answer is I don't read any such journals. And no one journal is sufficient to cover all areas re tomatoes.
But I've participated at many message sites in the past and same currently and when something comes up that I don't know about, in terms of a new disease, or anything else tomatoey, I then do an extensive Google search to get answers.
And over the last many decades I've kept current in that manner.
Years ago the Pest and disease Forum here was very very active , after Spike put up that Forum and the photo one as well, at the request of many here, and that so that the general Forum wasn't clogged up with disease and pest questions.
There were several of us who spent hours each day answering questions in that Disease Forum, but now I see so many such questions in this general Forum.
I also worked with the Cornell EXtension Office in several counties and learned a LOT about diseases when my tomato field was chosen as one for a disease survey comparing OP's with F1's which was done by volunteers working for the local Ext Office, under the supervision of the Directors, who were under the supervision of Drl Tom Zitter at Cornell, one of THE best tomato disease specialists I know of. And I've also taught Master Gardener classes on diseases and several other aspects of tomatoes.
The people currently posting here have not been here long, with exceptions like Dave and a few others and that's b'c in 2006 a different site opened and many went to that site and stayed there, and there are few of us who have been here a long time who still post here at all.
So no journals for me, been there and did that when I was working and grants paid for journal subscriptions which can be many hundreds of dollars/year.
But I do stay current in the manner that I described above, whether it's the spread of race 3 of Fusarium, the darn Gemini viruses that started in FL and now are spread along the Gulf Coast and on and on .
Carolyn, who, being retired has the time to do a lot of computer searching, via Google, to get answers to questions that she doesn't know the answers to or someone else wants answers. But I shy away from answering most questions here at GW about diseases, for a couple of reasons that make sense to me at least.( smile)

under a pine tree.
Under the drip line of a pine tree? Soil under a pine tree is by its nature, very acidic. Not only is acidic soil required for pines to grow but all the needles they shed every year are also very acidic and very slow to decompose and return even close to neutral.
There is ample evidence to support the lack of accuracy in the home soil test kits. Studies (see discussions here) show they will always test neutral pH, they will always test low N, and they will usually test low to normal P and K even though there is no known ow P soil in the US.
So with soil that is already acidic and now with all the peat added your soil pH is most likely well down into the acid range pH and most all nutrients are locked up in that soil and unavailable to the plants.
Lime, used to raise the pH back into a normal range takes several months to work so even after you apply it you are going to have to heavily over-dose those plants with nutrients - preferably in a liquid form so they can absorb them quickly - or dig them up and move the 3 of them to containers while they are still small enough to move.
As already mentioned a professional soil test, available for approx. $10 from your local county extension office or other local source is going to be the best way to get that bed back on track.
Dave

Actually, low P (as well as low pH) is pretty common in native CT soils, unless it's been fertilized in the past. But East Hartford is urban, who knows what Silken's soil is and where it came from. If it's under a pine tree and the pine tree isn't dying, for sure it's acidic and then you added peat which will make it even more so, unless you limed when you tilled the peat in. But you really need to get a lab test done to know what's going on. Soil sample needs to be dry, but Windsor isn't that far away and like I said CAES will do it for free, usually a week turnaround (though it was 3 weeks last month!).
At least if it's only 3 plants (?) it's not a big loss though it looks like you spent $ for drip hose? As Dave said, you can always grow tomatoes in containers (though I'd look for determinate varieties) this year, and get your soil in shape for next year.
Do you have some area of the lawn that has been limed for years and gets more sun that you could move them to?
Here is a link that might be useful: UCONN soil test interpretation


1) No experience with hydro ferts. However, Phosphorus is the P in NPK. The old teaching rhyme goes 'Up, Down and All Around'. Nitrogen stimulates top growth, phosphorus is for roots and flowers, and potassium is for all over vigor. So, with seedlings, it makes sense to give them a good root system--that's how they'll take in water and with it vital nutrients, and flowers are where tomatoes come from.
2) Grass clippings. I used to have drip hoses in the beds but the new dog chewed them to shreds when she was a puppy. I don't know if I'll be replacing them. I'm not really heartbroken over the loss of the hoses.
3) I planted seedlings last week, they barely had their true leaves. I do it each year--get them in young and they start getting their roots into the ground immediately. They were germinated outside. I do provide minimal protection from critters, bugs and birds. I cut the bottom off a water bottle, toss away the cap and push it into the soil around the seedling. When the seedling has leaves large enough to touch the bottle walls then it gets tossed in the green bin.
4)Not knowing the variety I'd have to say its their plant food.

1.) I use no hydroponic fertilizer at planting, I do sometimes throw in a little granular organic fertilizer in the hole at planting time - mostly for the beneficial microbes that are in it (tomato-tone). As far as organic fertilizers not having enough (plant available) phosphorous, that may be true, but, according to my soil tests, my soil has an excess of phosphorous so I am not really concerned about that; As an aside, I seem to remember reading that phosphorous-deficient soils are fairly rare.
2.) I layer mulch throughout the year, I use bales of hay in the early spring - generally March. I layer it deep (about 3 bales for 200 sq. ft.) and let it compact a little, then I plant through it some time in April / May. As the mulch breaks down I add some more hay some time in mid summer, generally around July. At the end of the season (November-ish), I clean up the dead / dying plants, pull the cages up and mulch heavy with stockpiles of homemade compost, and grass clippings mixed with leaves. I basically use whatever yard waste I have; I even steal some leaves from my fathers oak trees - he doesn't mind :) I use drip tape for any supplemental watering - I put it on top of the soil two years ago, and now it's been covered by a few successive mulch layers - has been working great so far. I recommend that you use mulch of some kind, but if you get lots of sun / really hot summers, and you want to use plastic mulch, I'd put some straw or hay on top of it to keep it from cooking your plant roots.
3.) I'm still conflicted about planting out tomatoes early. I'm very skeptical of weather reports, but I use them, plus a little bit of experience to judge when to put out my plants. With putting them out early you do risk losing your plants, but with my growing season, I just keep back-ups because it's worth the risk (in some cases) of losing a plant for the gamble of getting good warm weather early and getting tomatoes some time around July instead of August. I put my plants out on May 1st; So far the gamble is paying off since the weather has been great since then. All that said, if you're not sure about the weather, won't be around, and don't have back-up plants - I wouldn't chance it, though.
4.) The blue green leaves are more than likely indicative of the fertilizers they've gotten. High nitrogen will give that deep green, sometimes blue green, coloration.


Wow! Djole, you are going to be up to your ears in cherry tomatoes! How much sun does your garden get each day?
Betsy
Thank you for your comments, it means a lot to me :) it gets around 9 hours of sun at the moment, should be a bit more as the season progresses (more to do with the vertical position of the sun than the length of the day).
