Tomato constest!

My husband put me in the annual town biggest Tomato contest any suggestions on to to win for the BIGGEST Tomato??? Please any suggestions would be soooo helpful!!

First you have to choose a variety of tomato that naturally produces large fruit. A friend had plants he grew from seed called Big Zack and it grew the largest tomato I have ever seen. He told me it weighed 3lbs 10oz. He also told me that a 5lb fruit is not unheard of using this variety. A longer warmer growing season is also helpful. I called him and he told me he grew the plants with a single stem in straight well rotted manure. He watered and fed the plant religiously using a low nitrogen water soluble fertilizer. He only let a couple of the first tomatoes form picking of all the the newly formed blossoms and tomatoes. He had the plant in a wire cage and said he had to support the fruit with a nylon stocking. The smaller fruits were nothing to be ashamed of either all over 2.5 - 3+ lbs. A foot note: I am not sure if he told me all his secrets. He takes this stuff very seriously. Hope this is of some help.

Thanks! Yes I planted it in my large garden with alot of Mircle Grow potting mix! They gave us the plants and its a beefsteak variety. Just not sure what else to do for food for it?

If I my ask...
straight well rotted manure can you define this?? I have well rotted horse manure is that the same?

Horse manure is one of the best you can use.

I haven't tried this yet but thought I would share;

I do have steer manure and chicken too... when I move the brooder saturday, I am working in the soil under it to plant some things... Like the rouge watermelon that may be pumpkins.... HUM The jury is still out on that.

I read a book last year on how to grow giant tomatoes. I don't remember much of the exact details but here are some things that I recall.
There are some ways of pruning the plant that help it focus it's energy on growing giant fruit. (maybe something to look into)
Sudden excessive amounts of water after a dry spell will cause the fruit to crack- this is for any tomato but I guess the larger the fruit the more susceptible it is to cracking.
"Megablooms"- I guess some flowers are bigger than others and some of them 'fuse' together to form a larger flower. If you see this flower then it's the one that will grow larger fruit. I think you're suppose to help pollinate it ?
When you are growing for size, I think you're only suppose to allow a small amount of fruit to grow and pick off the rest. Further into the season, you keep on picking of the smaller sized/slower growing ones until eventually you only have a couple left.
I haven't tried any of this (bad disease on my tomatoes last year- completely different story) but hopefully it will give you some ideas of things to look into.

I;ll be looking ot hear more about this *G*. The way squashie things cross pollinate, it could be just about anything. I've had some very interesting results from volunteers...

For what it's worth, my tomatoes are insanely huge (although not to that extent), and I give them two weird things.

1) I buried an egg (pastured chickens, of course, but I'm just like that), under the plant when I put each one in the garden. I had read that it will help make the tomatoes happier, and what the heck, it's just an egg.

2) Every now and then, if I have any left over before my next milk-run, I pour a bit of unpasturized milk on the plants. Not often - like once a month - and only the milk that I drink, so I know that it's clean. But I think it's part of why my tomato plants are over seven feet tall and producing big fruits that are grouped almost like grapes.

Hmm. Considering the number of eggs my chickens produce, I could do that :).
Whole egg? With shell (good calcium), I'd guess? Maybe crushed?
Too late for this season, but the fall might be a go.

How about some crushed shell or oyster shell sprinkled in the topsoil?

Ok planted my red mater (Got two whites growing already) and took a freshly laid egg and put that in the hole...Willing to try anything to get a fresh mater...

In my case, after reading up on it, I planted a whole egg, not broken, under each tomato. I am wondering if it might be part of why the plants are apparently trying to take over the entire yard.

worlds largest mater is 7 pounds in the GWBR. good luck all !
