We still have plenty of lettuce to eat, although our first sowing of baby lettuce mix in the hoophouse has come to its bitter end, and the second sowing isn’t quite ready (I think we sowed it a bit later than intended). We are still harvesting leaves from the large lettuce we transplanted in October. Soon we’ll have the second and third baby lettuce mix sowings to bring a welcome change. We are about ready to transplant our first outdoor lettuce, to feed us mid-late April.
Here is a month-by-month planting and harvesting narrative for our hoophouse lettuce in Zone 7, from September to April:
September: Sow cold-hardy varieties in the second and third weeks (outdoors or in your greenhouse) to transplant into the hoophouse at 4 weeks old .
October: 4 weeks after sowing, transplant those lettuces at 8” spacing to harvest leaves from mid-November to early March, rather than heads. In late October, sow the first baby lettuce mix, for up to 8 cuts from early December to late February, and sow a small patch of “filler lettuces” to replace casualties in the main plantings up until the end of December.
November: 11/9 sow more filler lettuce, to be planted out in the hoophouse during January. Transplant the first “filler lettuce” to replace casualties. Harvest leaves from the transplanted lettuce.
December: Use the “filler lettuce #1” to replace casualties or fill other hoophouse space, for lettuce leaves in January and February, or heads in February. At the end of December, make a second sowing of baby lettuce mix, to harvest from late February to the end of March. Harvest leaves from the transplanted lettuce, and cut the first baby lettuce mix.
January: Use the “filler lettuce #2” to fill gaps in the lettuce beds up until January 25. After that is too late here for hoophouse lettuce planting, and we use spinach to fill all the gaps, regardless of the surrounding crop. Harvest leaves from the transplanted lettuce, and cut the first baby lettuce mix whenever it reaches the right size.
February: 2/1 sow the third baby lettuce mix, to provide up to three cuts, from mid-March to late April. In mid-February, consider a fourth sowing of baby lettuce mix, if outdoor conditions look likely to delay outdoor harvests. Harvest leaves from the transplanted lettuce, and cut the second baby lettuce mix when it sizes up. Harvest the first baby lettuce mix, clearing it at the end of February before it gets bitter.
March: Harvest leaves from the transplanted lettuce, and cut the second baby lettuce mix whenever it reaches size. Cut the third baby lettuce mix when it sizes up.
April: In the first half of the month, harvest the last of the transplanted lettuce as heads . Continue to cut the third baby lettuce mix until it gets bitter. Cut the fourth baby lettuce mix when it sizes up. Outdoor lettuce heads are usually ready for harvest mid-April. Plan to have enough hoophouse harvests until the outdoor harvests can take over.
The February issue of Growing for Market is out, including my article How to decide which crops to grow which I previewed some of here last August. I also included some of the material in my slideshow Diversify Your Vegetable Crops. Click the link to see the slideshow. This past winter we used this kind of process to reduce the amount of garden work for 2017. I’m retiring from garden management and the new managers want to stay sane and not be exhausted all the time. We have fewer workers this year (the past few years actually), so we needed to slim down the garden and not go crazy trying to do everything we’ve done in the past. I’ll still be working in the hoophouse, the greenhouse, and doing some outdoor work, as well as being available to answer questions and provide some training when asked.
Back to Growing for Market. There’s a great article for new small-scale growers, from Katherine Cresswell in northern Idaho, Year One Decision Making, about starting a farm with only one implement. Careful planning lead Katherine and her partner Spencer to focus on fall, winter and spring vegetables, as no-one else around them provided these, and they had experience of winter growing from working on other farms. Clearly a high tunnel (hoophouse) needed to be in the plan. It was essential that they hit the ground running and have saleable produce within six months. The expense budget was very tight. They bought a BCS 739 walk-behind tractor (which they both had experience of) and a rotary plow. A very down-to-earth article to encourage any new grower with limited means.
There are reviews of three new books by GfM writers: Compact Farms by Josh Volk, Floret Farm’s Cut Flower Garden and The Greenhouse and Hoophouse Growers Handbook by Andrew Mefferd, the editor of GfM. Brett Grohsgal has written a valuable article about his 15 years experience with on-farm breeding of winter-hardy vegetables, both in the field and under protection of hoophouses. Informative and inspiring. Erin Benzakein has written about rudbeckias, the unsung heroes of summer bouquets, and Gretel Adams has written on new flower varieties to try in 2017.
I have a new post on the Mother Earth News Organic Gardening blog, Using Open Flats (Seed Trays) to Grow Sturdy Seedlings Easily – How to make reusable wood flats (seed trays) for seedlings, and use them to grow sturdy vegetable starts to transplant into your garden. This is a way to avoid contributing to the problem of agricultural plastic trash and be self-reliant in gardening equipment. You can also grow stronger plants by giving them a larger compost volume than plug flats or cell packs provide.
I heard that my MEN blogpost Green Potato Myths and 10 Steps to Safe Potato Eating was very popular in January, coming sixth in their table of most-viewed posts on all topics. This has been out there in the blog-iverse for almost 18 months, so clearly there is a lot of concern about eating healthy food and not wasting what we’ve grown.
The false spring has been barreling along. Last week I reported that we’ve seen a flowering crocus (2/17). Since then, we’ve seen daffodils and dandelions flowering, heard spring peppers and already the maple is flowering (2/25). These are all markers on our phenology list. The maple flowers on average 3/12, with a range (before this year) of 2/28 in 2012 to 4/2 in 2014. A 9-year record broken!

Hi Pam, Even though I assume you’ll stay active in different aspects of gardening and garden education, your announcement on your upcoming retirement from managing the gardens did make me pause and remind me that I wanted to send you a long overdue note of appreciation. You’ve given me so many useful inspirations that I don’t want them to end. Fortunately, I’m still gleaning more and more from your book and blog. A year ago, I had our library order your book and have checked it out many times. Then this spring when I wanted to read more about your nursery beds, it was checked out and overdue. I should have bought my own copy awhile ago, but I’m excited my own copy should arrive any day. We’re trying to be a low-tech diverse market farm and your low-tech approach, like wooden flats and nursery beds, have been the perfect advice for our situation. Thank you for sharing your experience and knowledge. And selfishly, I do hope your “retirement” involves keeping your blog going and giving workshops.

Hi Melissa, Thanks for your appreciations! I’m definitely carrying on with my blog, and with giving workshops. In fact I’ve started writing another book (about year-round food production in hoophouses). Pam
Regarding the reusable wood flats (seed trays) for seedlings, how do you clean the flats between seedings to avoid disease from year to year, or has this not been a problem?
We scrape out the wood flats and let them dry in the sun before we use them again. We haven’t had any problems with disease spreading. I’m more the muck-and-magic school than the sterilize-everything school
Thanks for the wood flat solution! Starting “mortgage lifter” tomatoes, chard, lettuce, Echinacea, sugar snap peas..etc in our Monroe, NC garden. Can’t stay out of the Southern Exposure Seed catalog! Love the heirlooms Thanks for the info and the blog
After I posted about wood flats I found that Noel at Cobrahead Tools was writing on the same topic: http://blog.cobrahead.com/2017/02/07/wood-garden-flats/.
