we've grown roma's a few times and they produce here about the same as the beefsteaks. so that means between 20-40lbs per plant. i don't know what your local conditions are like or what you normally get or how long your season is. when we had 30-40 plants it was too much and we gave a lot of canned tomatoes away. this year we are growing 15 plants of a new variety and not sure how well they're going to do with this weather and all. they look ok so far. as a rough conversion for lbs of fruit per quart canned we get about 7-8 quarts of tomato chunks per bucket of tomatoes. i can put up 20-30 quarts of tomatoes in 2-3 hours time (the condition of the fruit can change this quite a bit). juicing takes a little longer if we're doing that (we haven't been the past few years).Anxious to see what the garden produces late this summer. I may have gone a bit overboard when I planted 80 or more tomatoes. I did a few varieties including:
About 10 or 15 Big Mama's
15 or more San Marzano's
3 or 4 early girl
2 or 3 Big Boys
5 or so Better Boy
Some Independence Day
Some Canadian version of independence day called Manitoba, about 5 of them.
10 or 15 Roma
I did 2 rows spacing 2' apart with marigolds in between for pest control. This was July 8th and was weeded shortly after this pic was taken, sorry for the mess.
Dad is up at our camp now, I won't be back for 10 days or so, but I have pruned heavily taking a lot of suckers, and tied them up to the fence. My first year becoming tomato crazy, and I realize I have overdone it by at least a factor of 4. What i would like to know is for anyone growing Roma, San Marzano's and big Mama's - how many lbs do you get per plant on a good year? How many people would I need helping to process 800+ lbs if tomatoes if it comes through?
It was a lot of work. Though my Dad and I are keeping it up, I did all the tilling, stone/boulder removal(which was a considerable task, last year I removed about 8 or 10k lbs of all sizes and shapes rocks and boulders). My Dad's cousin has a beef farm not far and gave my dad a bucket load of really well composted manure that I was able to spread and till in. That has likely made a big difference. My family went down with me the 2nd weekend of July for 4 days and it was pretty much all out for 3 days. One of the first time my kids and even my wife helped with weeding. That gave me the time I needed to prune and tie up the bulk of the tomato plants, and top trimmed the peppers. I waited all winter, and now that summer is here, it has breezed by so quickly that I'm not sure I'm enjoying how fast time is flying by., I think next year I will scale it down and try to do less, but it's a hard thing to do for me.I am envious of such a nice, weed free garden. You should certainly be busy canning with that many plants. You must be feeding a village. Or a football team or two...
