I have not been able to focus on a Giant Tomato Project since 2014. Although I got a good start in 2015, I was forced to abandon that in mid-August.
So here we go for 2017! Not ideal conditions, as I live more than two hours away and will only be able to tend these plants a few days per month; but I can still hope for something in the 4-5 lb. range, as well as plenty of otherwise BIG tomatoes for fresh eating, etc. Sure, I would love to break the world record (currently at 8.61 lbs.), but given the circumstances, I’m not going to indulge in that delusion.
I will revise and update this particular blog post throughout the growing season with noteworthy developments.
First – where to grow them? A new high tunnel in Pleasant Grove, dimensions 55′ X 14′. Here’s the beginning of that, cutting lumber and prepping the ground on April 21st.
The completed high tunnel is shown in a previous post.
Taking a cue from the successes and advice of several other giant tomato growers, I did not start any seeds for this project until the first day of May. Using 24 one-gallon pots for the more “precious” seeds, I filled pots mostly full with rich potting mix, made a depression, added sterile seed starting mix, some mycorrhizal fungal spores, then more seed starting mix, then the seeds. The idea is to start seeds in a sterile, nutrient-free medium, but have plenty of nutrition available as the seedlings grow, without the need to pot them up – and thereby disturb tender young roots – prior to transplanting them into the garden.
May 10th, filling in with more potting mix to encourage root grow along stems and moving young seedlings out to sit on the pickup truck to get their first taste of natural sunlight.
Only 12 of 24 seedlings in the gallon pots ever emerged; 11 of the 12 no-shows were all from the same source.
May 18th – young seedlings for this project and preparing the soil with about 4″ of horse manure – that might be too fresh but it was free.
Arrangement of high tunnel:
Two paths, 2′ wide and depressed about 8″.
North bed, 2-1/2 feet wide, planted with melons and cucumbers
South bed, 2-1/2 feet wide, planted with peppers and eggplant
Center bed, 5′ wide, giant tomato project with two rows, seedlings placed 2′ apart along double drip hoses with emitters aligned.
June 2nd, 32 days from seed sowing – prepping and amending soil (organic products only in this business – see OMRI labels), laying out drip hoses and transplanting. Trenches dug, soil removed and mixed with amendments of peat moss and Ecoscraps Compost. Additional mycorrhizal fungal spores added at the base of each seedling and trenches eventually filled in with the mixture as well.
I managed to squeeze in 48 seedlings for this giant tomato project of 28 different varieties and/or lineages as follows (20 duplicates not listed):

Update June 16, 2017
High tunnel tied open and shade cloth installed just ahead of potentially 100° plus weather:
This setup of shade cloth over a high tunnel was reasonably successful for producing giant tomatoes three years ago, so why not try again?
Plus adjustments made with drip system, as the south row was getting little water.
Healthiest looking seedlings and developing megablooms inside the high tunnel include:
Bezrazmernyi (3.364 DT 2014)
Безразмерный translated to Dimensionless:
Bigzarro (3.754 DT 2014)
Bill Bean Select:
Megazac (6.13 Konieczny 2016):
Michael’s Portuguese Monster X Delicious (6.51 Meisner)(F2), with the largest seedling and most impressive megabloom developing:
Outside the high tunnel in the main tomato patch, a very impressive cluster of flower buds, including a megabloom, is forming on a Russkiy Razmer Rozovyy vine.
Русский размер розовый translates to Russian Size Pink.
— Two photos of this same plant on 7-10-2017:
And the largest vine to date, though without megablooms, is Staroobryadcheskyi; Старообрядческий translates to Old Believers:

Update July 9-10, 2017
Returning to the Giant Tomato Project after three weeks absence, I find a high tunnel almost overrun with gangly tomato vines. I had pruned all of them to 1 or 2 stems, but they have grown like weeds!
All except two vines (Chilo della Garfagnana and Church) which got hit with Curly Top Virus (as did another 42 in the main tomato patch)
First pruning and tying up on July 10th – all but two stems per vine terminated.
In the high tunnel, where the Giant Tomato Project is, these are the fruits which have developed from megablooms and show some promise for growing large.
Russian Oxheart (4.66 Spaziani 2016), 2X
Zaczilla (1.832 DT 2016), 3X
Michael’s Portuguese Monster X Delicious, 3X
Delicious (3.205 DT 2014), 3X
Dozens of blossoms, including megablooms, have burned up in the hot sun – not so surprising considering that 13 of the past 20 days have topped out at 94-105°F
In the main tomato patch, a good-sized double blossom set fruit on a Bukharskoye Bych’ye Serdtse vine:
A couple of megblooms in the main tomato patch:
MegaMarv (Khilenko 2016), 4X – but yellowish tinge indicates it may be headed to aborting.
Rufus Carrigan’s Mexican Pink, 3X
But presently, the best megabloom is a 4X on a Michael’s Portuguese Monster vine in my sister’s garden:
This is from the same seed that produced a 3.754 pound Utah state record largest tomato in 2014.
