Large Tomato variety that WILL grow in Seattle

I've had luck with cherry tomatoes but still can't find a variety of large tomato that will reliably produce in my Seattle sun garden. I've heard that there are a couple varieties that do well but I don't know what they are. Thanks for the help.

    So THIS question you ask is the perennial question to our annual tomato obsession here is the PNW...big tomatoes are elusive to us here.

    There are always the varietals that have chilly names, like "Glacier"; any tomato with a Russian name indicates hardiness. "Early Girl" has always been the hands-down winner at our farm for earliness (not that it DOESN'T taste like cardboard)and there is a new and improved Early Girl named 'New Girl' that is better-tasting than EG. Oregon Spring is a good-sized open-pollinated tomato, and a determinate.

    BUT, here is our new theory at Oxbow Farm: grow the early heirloom varietals rather than horrid-tasting groomed-for-earliness hybrid tomatoes. We have found some heirlooms that are GREAT tasting and pretty much as early as any other hybrid. SUCH AS: Jaune Flamee (an smallish-orange acidic tomato), and Black Prince, a gorgeous chocolate-brown rich-flavored tomato that is a bit larger than JF.

    YES, neither of these are large. Tis the CURSE of our climate, eeking out small tomatoes unless you have plastic protection. For large slicer heirlooms, I would try Prudens Purple, an earlier Brandywine. My FAVE hands-down.

    (SHAMELESS PLUG: we at the Oxbow Farm stand have all these vars. for sale at the Ballard Farmers Market (Sundays) or the Madrona Market on Fridays 3-7 at 23rd and Union.

    Here are some cultural techiques to use when growing your outdoor tomato, so's you can reap as much as possible by growing them smartly:

    1. Grow them in front of any reflective surface--a south-facing wall or a brick/stone/concrete wall will give you much more residual heat than without any reflective material.
    2. Learn how to prune them well. Tomatoes love to grow luxurious sidevines and leaves when left to their own devices, and these detract from any fruit production. Important to have sun and air circulation in there too, another reason to prune.
    3. Trellis them well onto a strong bamboo trellis, and not in one of those cages that trap in their foliage.

    May the force be with your tomato on this chilly spring! Hopefully it will yield to heat soon.

    So far, you’ve received excellent advice, including Sarah's terrific tips and where to find her farm's recommended varieities. So, here are few more thoughts....

    When I think about growing tomatoes, I, too, am forced to acknowledge the difficulties we face in a maritime climate. Tomatoes love heat and, well, we don’t have much sun or heat until long after the official start of summer on June 21.

    In fact, did you know many local meteorologists, the National Weather Service, and UW Prof. Cliff Mass say July 12 is the real beginning of summer in Seattle? It’s no wonder we have trouble with growing tomatoes and can't reliably schedule July 4th BBQs. (See Cliff Mass’s blog: http://cliffmass.blogspot.com/2010/06/first-day-of-summer-when-will-it-be.html.)

    Back to growing tomatoes, Master Gardener Wally Prestbo is known as the “tomato guy” at the Bellevue Demonstration Garden. Wally and his crew plant 2,000-3,000 tomato seeds every year in several greenhouses for the Master Gardener Plant sale. These tomatoes are tested for flavor and reliability. Additionally, each spring Wally teaches a free workshop about growing tomatoes at the garden --this year’s workshop took place in April. If you’d like to meet Wally, he is often at the Bellevue Demonstration Garden Wednesday mornings tending his tomatoes and is always happy to share his knowledge.  For garden location, hours, and events see: http://www.mgfkc.org/resources/demonstration-gardens/bellevue-demonstration-garden

    So, what does Wally recommend? Read Valerie Easton’s 2007 interview from The Seattle Times: http://seattletimes.nwsource.com/html/pacificnw/2009076642_pacificfootgardener19.html

    Finally, check out two WSU Extension Fact Sheets: #35 Tomato Problems http://king.wsu.edu/gardening/documents/38TomatoProblems_001.pdf and #52 Tips for Growing Tomatoes http://king.wsu.edu/gardening/documents/52TipsforGrowingTomatoes_000.pdf

    Happy planting!
    P.S.  I've had limited tomato success and generally stick with cherry tomatoes. (sigh)

    This is our second not so great spring/summer in a row.

    Stupid jet stream anyhow.

    I like to listen to the KUOW "Greendays" garden show, Tuesday mornings.

    You're gonna have to help them out with the whole heat thing. Cloches, row covers, a cold frame - something. I hear at garden centers they have plastic sheeting with little vent holes built in. Maybe you could get just enough for your tomatoes.

    My friend's birthday was Wednesday, it was cold and rainy, last year we had a picnic outside.

    Year before that I had a picnic in the park in FEB! Remember that?

    Maybe next year Tomatoes will take less intervention. Our springs and summers are usually pretty great.
