Lettuce Varieties for 2017

We’ve just updated our Lettuce Varieties List for 2017, removing ones that didn’t do well last year, highlighting ones that did do well, and checking which dates work for which varieties in our climate (central Virginia, cold-hardiness zone 7).

I tried to paste in the list, but failed (I know I’ve done it successfully before!) so here’s a link and some photos

When I posted my Lettuce Varieties for January article, Wanda commented on the great varieties available from Frank Morton at wildgardenseeds.com. They do have some wonderful lettuces, so I’ve included a couple of pictures of their varieties  that we grow, above.


I’m short of time today, I’m getting ready for the Southern Sustainable Agriculture Working Group Conference. Check out my Events page for more about what I’m doing there. Two brand new workshops, and book signing. I hope to see some of you bringing your dog-eared and mud-splattered copies of Sustainable Market Farming for signing on Thursday evening. I’d love some photos of well-used copies of my book!

Lettuce varieties for January, new year, fresh start

Maybe you aren’t ready to think about sowing lettuce, but I am! In mid-January we sow a flat of four lettuce varieties, to become our first outdoor transplants. I like to choose four varieties that cover the range of colors and shapes.

I also like to choose hardy types that are fast-maturing. Buttercrunch green bibb lettuce is one of my favorites for early spring. One of the Salad Bowl lettuces, red or green, is also usually in my first sowing. The Salad Bowls are so reliable and productive!

New Red Fire has become another reliable lettuce stand-by for us. It was suggested to me by neighboring Virginia farmer, Gary Scott of Twin Springs Farm. It is more of a leaf lettuce, and doesn’t really head up, although it can be cut as admittedly lightweight heads. And it works fine as a leaf lettuce, to be harvested by the cut-and-come-again method. We grow New Red Fire year round, it’s that adaptable and easy-going.

After last year’s success with Sword Leaf lettuce, which I wrote about last May, we have added this variety to our list of favorite lettuce varieties. But if I start those four, I won’t have a romaine and will have only one red. We haven’t found many good full-size red romaines. Rouge d’hiver is a possibility, although I wonder if it would bolt too easily (it’s more famous for growing in winter). A better choice might be Bronze Arrow (it worked well last year and we were harvesting it in early May).

We expect/intend/plan to start harvesting heads of lettuce outdoors starting 4/15. Before that we will harvesting the lettuce in the greenhouse and the hoophouse.

As you see from the top photo, we grow our outdoor lettuce as bare root transplants, starting in open flats. I’ll write about bare root transplants next week. We find it an easy, forgiving method for many crops.  For now, I’ll just talk about the lettuce. We sow in 3″ deep open wood seed flats, 12″ x 24″. We make four little furrows by pressing a 12″ plastic strip (aka a ruler!) into the seed compost. We sow the seed, label it, cover it lightly, water, then put the seeded flats in our germinator cabinet. The first flat of the year takes about 9 days to germinate. According to tables in Nancy Bubel’s Seed Starter Handbook and in Knott’s Vegetable Growers’ Handbook available free online as a pdf here, lettuce takes 7 days to germinate with a soil temperature of 50F (10C) or 15 days at 41F (5C), and only 4 days at 59F (15C).

Once the seedlings are big enough to handle, we spot them out into 4″ deep flats (also 12″ x 24″). We have a plywood dibble board with pegs evenly spaced about 2.5″ apart. You can see the offset pattern in this next photo:

We aim to harden off the lettuce for two weeks in the cold frame before transplanting into the garden beds with thick rowcover on hoops to protect the lettuce from the still-cold outdoors. To be ready for harvest 4/15, these seeds have to become full size lettuces in 88 chilly days.

We make a second sowing on 1/31. The intervals between sowings at the beginning of the year are long, because later sowings will to some extent catch up with earlier ones. Almost all crops grow faster in warmer weather (up to a point). We sow lettuce twice in February (every 14 days), then every 10 days in March, reducing the interval down to every 6 or 7 days by the summer.

As far as varieties go, we think of The Lettuce Year as having 5 seasons: Early Spring January – March, Spring April 1 – May 15, Summer May 15 – Aug 15, fall August 15 – September 7 and Winter September 8 till the end of September and our break from sowing lettuce.

Some of the early spring lettuce varieties will bolt prematurely here if sown after March 31. Examples include Bronze Arrow, Freckles, Merlot, Midnite Ruffles, Oscarde and Panisse.

Others that we like in early spring go on to be useful in spring too. All the ones mentioned as possibilities for sowing #1 are in this category, as are Green Forest, Parris Island, Kalura (three green romaines), Nancy and Sylvesta (two big green bibbs), Pirat (a red bibb), and Star Fighter (a green leaf lettuce)

I have written blogposts about growing lettuce in October, September, August, July, June and May. On October 25, I reported that we have covered our last outdoor bed of head and leaf lettuce, and an “emergency” bed of baby lettuce mix with double hoops and rowcover. Now, one month later, we are waiting out this cold snap (19F/-7C last night) until we get a mild spell to uncover those beds and finish harvesting them. We want to move the hoops and row covers to the outdoor spinach beds.

We are now harvesting only winter salad mixes, no more big bowls just of lettuce. We are using leaves from the outdoor lettuce, the outdoor lettuce mix, or leaves from the lettuce in the greenhouse, according to whatever is most ready. We chop the lettuce up as we harvest. I start with about half of the harvest bucket full of chopped lettuce. I notice that it takes 3 half-buckets of harvested greens to fill one bucket! The greens settle, and when mixed they take less space than they started out using.

Lettuce varieties we are currently harvesting include Green Forest, Hyper Red Wave, Merlot, new Red Fire, Oscarde, Panisse, Red Salad Bowl, Red Tinged Winter, Revolution, Salad Bowl, Star Fighter, Tango, Winter Marvel and Winter Wonderland. Last winter we grew some Osborne Multileaf varieties we liked a lot. This year I learned the hard way that pelleted seed doesn’t store well. As pointed out by Johnnys Seeds in their JSS Advantage Newsletter January 2012

“Some seeds, particularly lettuce, are primed before pelleting, which begins the metabolic process leading to germination. Because some of the early steps toward germination are completed before the seed is planted, germination happens more quickly. Germination times can be 50% faster with primed seed. When seeds germinate quickly, they may avoid potential problems including soil crusting, weeds, and soilborne diseases. On the down side, primed seed doesn’t have the same storage life as unprimed seeds, so we recommend that you purchase only enough for the current season.”

I like to mix three crop families in every salad mix: lettuce, spinach/chard/beet greens/brassicas. I also like to mix the colors and textures, so if most of that day’s lettuce leaves are green, I’ll be sure to get some Bulls Blood beet leaves or Ruby Streaks or Scarlet Frills. I don’t make the same mix every day, as variety is the spice of life!

I love the taste of spinach leaves in salad, and we have lots of spinach (outdoors, in cold frames and in the hoophouse). I love the colors of baby Bright Lights and Rainbow chard. I chop those stems small – not everyone likes a big hit of chard flavor in their salad. When I harvest Bulls Blood beets I snip the stems close to the base of the plant, line up a handful of leaves, then snip off the stems just below the leaf blades, before chopping the leaves into the bucket. These stems are kind of wiry, not good food. I don’t like to leave the leaf stems on the plant for two reasons. One is that the stems “cage in” the developing plant, reducing the access to sunlight and photosynthesis. The other is that the stems die back later and rot. Better to remove them right away. I do the same with spinach.

Last month I mentioned the brassica salad mix we sowed in our hoophouse 10/2. We have made three cuts already – very good value for the tiny amount of space occupied. Mizuna, Ruby Streaks, Scarlet Frills and Golden Frills add a ferny shape and some loft to the mix. Mizuna is very mild, the other three are spicy. Other brassicas we are currently cutting small for our salad mixes include tatsoi and Russian kales (red and white). At some point, deeper in the winter, we’ll try to leave the kale alone to grow big for cooking greens. This will happen when we are shorter of cooking greens than salad items, and the kale has become more robust. Some of the crew are more hardcore than me, and include sturdier greens, like senposai. Later in the winter, other crops will come to the fore.

We also include as microgreens any thinnings from recently sowed rows of almost any greens, including radishes and turnips if they are not bristly-leaved varieties.

Our 10/24 hoophouse sowing of baby lettuce mix is almost ready to harvest – maybe in the next week or so. We have made an 11/2 second sowing of mizuna and friends, but the seedlings are still tiny, showing a big difference between the temperatures on 10/24 and those a week later on 11/2.

For cutting lettuce I like the plain steel scissors from Lee Valley. They are sturdy, easy to tighten and sharpen and ambidextrous. They are a traditional Chinese style.


Lastly, for those of you who want to know more about the Twin Oaks garden specifically, let me introduce you to the Twin Oaks Garden blog. It’s written by Wren Vile, one of the upcoming managers. I will be retiring as garden manager on March 1 2017, and Wren and Brittany will take over the day-to-day running of the garden. I won’t be going away, I’ll be around to answer questions, and I will continue to do some work in the garden, around the “edges”, rather than in the thick of the shifts. I’ll have more time for my writing and speaking on vegetable growing, and I’ll have more time off!

Growing for Market February issue is out! So is USDA Climate Change Report!

GFM-February2013-cover-300px

The February 2013 issue of Growing for Market magazine is now available, including my new article  Making Good Decisions Under Pressure. This is the fourth article in my series about being resilient, understanding what’s going on with the plants and the weather, and knowing when to take action, is about tools to help busy farmers with complex decisions that have to be taken quickly. The middle of a hot field in mid-afternoon of the day you need to plant is not the best place to make a hard decision. It’s better to have a framework in place to lean on when the going gets tough. I talk about various decision-making techniques, clarifying whose job it is to make each decision, what resources are available, and what the impacts of the decision might be.

If that sounds abstract, I also include our sad chart “Can’t Do It All 2011”.  In early March that year, we realized we had nothing like enough experienced workers. We were looking at an overwhelming amount of work. We made a list of labor-intensive crops for possible cuts. The main point was to save us time, not just cut crops we personally disliked! We noted the decision date by each crop on the list. As each date approached we reviewed our situation. This method enabled us to make one decision at a time, in a straightforward way, and not go insane. Such a list is helpful for many types of calamity. It leaves the door open for possible upturns of fortune later in the year. It’s less distressing to take one bite at a time than to take a big decision when you already are struggling to cope with some big bad thing having happened.

This issue of GfM also has these articles:

• Lettuce varieties that tolerate heat and cold By Lynn Byczynski

• Book Reviews: The Organic Seed Grower (John Navazio) and The Art of Fermentation Sandor Katz) by Lynn Byczynski

• A new meal-planning service keeps CSA members happy by Lynn Byczynski

• Capturing information in the field to help with recordkeeping, by Chris Blanchard

• Plans for farm-built pallets that make it easy to move transplants, by Chip and Susan Planck

• What the proposed federal produce safety rules mean to you, by Lynn Byczynski

• An urban flower farmer builds a flourishing business in weddings, an interview with Jennie Love by Erin Benzakein.

Also newly arrived is the Report Climate Change and Agriculture in the United States: Effects and Adaptation (USDA Technical Bulletin 1935). I wrote about this in my post following the CFSA conference in October, where I attended a gripping workshop by Laura Lengnick, one of the authors of this report. It has 193 pages, and when I’ve read it, I’ll review it. Chapters include An Overview of U.S. Agriculture, An Overview of the Changing Climate, Climate Change Science and Agriculture, Climate Change Effects on U.S. Agricultural Production, Climate Change Effects on the Economics of U.S. Agriculture, Adapting to Climate Change, Conclusions and Research Needs, and various appendices.
