  • Winter Harvest plans

    I've just bought "The Winter Harvest Handbook" by Eliot Coleman and want to try to make the best of harvesting over winter, as well as during the summer. In particular:

    * plan what to do in the (unheated) greenhouse - I'm currently thinking lettuce, spinach, perhaps pak choi / other asian greens, lambs lettuce in the long narrow raised bed - to follow on from the tomatoes

    * also in the greenhouse - replace the current buckets of cucumber, aubergine, peppers, chilli with buckets with chard, perhaps cabbage?, beet leaves, carrots, perhaps winter radish, other leaves

    * experiment with the SFG bed - I've just today sown all sorts - lettuce types, chard, spinach, carrots, beet leaves, raddichio etc (the bed is 1.2m x 2.4m so a double-sized SFG). I plan to put a mini-polytunnel over this, and try the double protection idea i.e. inside, cover with fleece held up by low wire frame, outside polytunnel plastic over hoops. Eliot Coleman uses this on his farm - he farms in Maine so they have longer days but down to -25 degrees in midwinter!

    * try the outside polytunnel idea on another raised bed for spinach - sow in September to get this started, then pick monthly to see how long I can keep this going - apparently spinach continues to grow over the winter

    * try in another raised bed with probably just fleece, sowing late leeks and possibly turnips and carrots, for harvest in Feb-time? (not sure about this, he is not clear about timing for sowing leeks)

    These are all experiments for me - the greenhouse is new, and all I've done before is overwinter mustard under fleece (which worked pretty well!)

    What are your plans for winter harvest? What have you done before, and how well did it work? What are the latest dates for sowing for either uncovered cropping or covered (fleece or polytunnel)? Has anyone tried the double cover idea, and how did it work?

    It would be great to collect ideas in one place for specifically winter harvesting - so any suggestions or questions please add to this thread!

    regards

    Sounds like a good plan, Salilah

    I have a second sowing of brassicas to grow overwinter in the veg bed (1st lot demolished by the dreaded cabbage white! ) Kale and PSB plus celeriacs salsify garlic and broadies. I am planning on growing some winter salad in my porch!!
    We only have a small (well compared to some) patch, so have to be pretty picky with what we grow.

      If you like a few blooms for the house either Chrysanthemums or Carnations can be planted in pots, left outside during the summer and brought inside after the toms are finished to bloom up to Christmas and even into the new year!

        I don't have a tunnel or greenhouse. But I try and sow things later in the year so that we have veg through the winter. A fleece cloche is very useful. I grew some Kailaan and red russian kale - they were great for eating through the winter as you could steam them or eat them raw.

          I've had mustard (osaka purple I think) under a fleece cover before, and they survived pretty well!

          What are your latest dates for sowing for a winter harvest? I've some kale out but unfortunately didn't net, so the caterpillars are enjoying the little leaves rather than me!

            I've successfully done the below:

            In greenhouse:
            Meteor peas - for pea top salads throughout winter
            Pak Choi
            Winter Purslane
            Corn Salad
            Oriental Salad Mxt
            Chard
            Rocket


            Outside in cold frame: (experiment)
            Rocket
            Corn Salad

            Unprotected:
            Corn Salad
            Winter Purslane
            Kales
            Winter / Spring Cabbages

            I *think* i planted up last year in end of Sept - records elsewhere currently - and found that the everything was protected enough in the greenhouse, with the peas and the oriental mustards growing away well. In order to harvest the others before very early spring, they needed to be planted earlier. I'll aim to dig specific date records out later.

            All the plants came to a standstill after some growth, so I'm looking to go into winter with larger plants that can be harvested as and when, using the greenhouse as a large fridge in essence, and so this year I've just planted up (1st August) - and we'll see how we go!

            The cold frame worked well last year, although again, it was a later crop. I wasn't sure that this would be enough protection for the rocket - but it did just fine.

            This year I'll also be trying:
            Cold stored Vivadi potatoes for xMas new potatoes - growbag in greenhouse
            Autumn king carrot, stored "in situ" under cardboard and polythene

            Always interested in extending the season - having read it, would you recommend: The Winter Harvest Handbook?

              The book suggests
              a) apart from spinach and winter purslane, everything else more or less stops growing (or semi-hibernates) once day length gets to around 10 hours - so from late october through to early Feb. However if the plants are still alive, it does mean you can harvest leaves etc - as you say, using the greenhouse like a large fridge!

              b) I'm wondering if 1 Aug is too early - the book also commented that smaller plants do better in winter than larger - they are more adaptable? Though - not clear what "smaller" means!

                buy the book?

                Yes I think so! It is not particularly cheap, but it does cover an awful lot! He has a small farm, so a lot of what is commented on is for a larger scale (much larger) but I think some of the ideas are worth adapting... For me, he is not specific enough on some details (e.g. dates for sowing leeks) and a bit too specific on other things (you'll learn several ways to move large polytunnels, and details of how to market your veg to restaurants and shops!) that I don't quite need
                It's also fairly US-focused so the materials etc are all US and need converting (number 9 wire anyone?). Overall though, an inspiring read!

                  I'm afraid that I only have somewhat patchy notes but here's what I have:

                  2008 season: - in greenhouse with layer of bubble wrap
                  1st Nov: ...planted up: 1 bag Meteor, 1/2 bag rocket, 1/2 bag Oriental Greens, 1 bag Pak Choi, 1 bag Rainbow Chard.

                  26th Dec: started harvesting pea tops, 4 portions today, growing v. well. Rocket also approching harvestible size but mustard greens, Pak Choi, chard a long way from usable.

                  5th Mar 2009: ...rocket now bolted - pulled up and resown at 5 inch spacing. pack choi starting to bolt with the longer days. Chard making headway again...

                  2009 season:
                  - in greenhouse without layer of bubble wrap

                  No specific record of the sowing date, but would have been moved to Sept /Oct roughly. Doh!

                  6th Mar 2010: bubble wrap now back on greenhouse. Pak Choi, peas and oriental salad have come through during winter but not put on anything like the same growth despite being planted earlier. Needs the insulation.

                  -2 degrees tonight...


                  2010 season:
                  - will be in the greenhouse with the bubblewrap this time.

                  1st Aug - first sowing of Pak Choi and Meteor Peas for pea tops.

                  others (and second sowings) to follow shortly...purslane now sows itself freely in and out of the greenhouse so it's always on standby somewhere...

                  Thanks for the review of the book as well salilah - it sounds pretty interesting so I'll investigate.

                    Sounds like an excellent idea for a book.

                    Just talked to one of my allotment pals and asked him whether he had sown his spring cabbage yet "Oh no" was the reply " I never grow anything on the plot over winter"

                    Whats the point of paying an annual rent for a plot, then only use it for about half the year? Why have a brown weedless desert for the winter when you could have a crop on it?

                    If I had the technical knowhow I would write a book myself, geared to growing outdoors and indoors through the winter in Britain!

                      But - don't you have the knowhow? I was surprised that there were not more books in the UK for this - admittedly as EG says, we are "on the polar bear line" here in the UK for daylight hours, but temperatures we are not that bad - certainly a lot warmer than where he farms in Maine!

                      I'm interested in teh idea of 2 covers - an outside one (greenhouse or minipolytunnel) and inside one (probably fleece) - will be interesting to see if that makes a difference.

                      Agree re the waste of ground over winter - it doesn't feel right to have these empty spaces when we should be able to keep eating!

                      What other "knowhow" can we collect that we have found works for us?

                      cheers

                        Great thread Salilah, and great replies from all. Have been thinking a lot about Winter veg, as Snadger said it is wasteful not using during the winter months!

                        Not sure how they are going to turn out but I have sown a load of swede seeds on the 1 August in a hope to get some going ready for the winter. I have also put some leek seedlings in which are currently at about 2mm in diameter. In addition I have planted a load of PSB, currently only small but hoping to get them going nicely during the remaining part of the summer. Trying Curly Kale again this year , last year they never really took off and were very disappointing. However going to dig some chicken manure in this time to hopefully help them get under way, as I love eating Kale and missed out last year.

                        Hoping to get a few salads and spinach etc going in the green house as I have never used it throughout the winter before. Thanks for the tip about bubble wrap, think I will definitely use some for added protection.

                        Lastly, will I need to give my broadies any protection throughout the winter or can they just be left to the elements? Guessing it will be better to use some fleece?

                            The two I rely on most are Spring Hero, a ball headed type & Durham Early, a pointy variety.
                            I am also giving spring greens a try this year which don't heart up and another couple of pointy varieties!

                              Thanks a lot Snadger, I will give those varieties ago.
