Extending our Season Extension

Thanks to a grant from MidOhio Foodbank, we purchased some new season extension supplies this year. Some of what we got replaced things that were worn out or damaged, including the endwalls of our high tunnel. The most useful thing so far were two lightweight cold frames (also known as “hot boxes” since they capture sunlight like tiny greenhouses) we used to start seedlings for fall greens.

For the past few years we’ve been starting seeds in a cold frame The Spurgeon General build and set in the ground up by the house. It’s a great way to start a lot of plants all at once, without need for acclimatizing. Since they germinate and start growing outdoors, the seedlings are prepped for their move to the farm, under low tunnels to protect them from hungry bugs and and quadrupeds. With this system we can start hundreds, probably more like thousands, of seedlings at a time, with minimal effort. Keeping a 2 x 4 foot seedbed moist is a lot easier than a 24 foot row! The jump start the plants get in the frame, saves us time and space on the farm. Since we’re so small, this really impacts our growing capacity.

These new hot boxes are so light they can be lifted by one person. They have aluminum frames andĀ UV-stable polycarbonate sides (which I am curious to see the longevity of) and screens – as well as solid – tops so they keep pests out and let rain in. We can use them in various locations, as space becomes available, then lift them up, move them to another spot, and start again.

We’ve used the frames for two rounds of seedlings over the past month and look forward to playing with them again, inside the high tunnel, after the Persephone Days have passed and things get growing again at the end of January.

Field Report: March 26, 2017

We’ve had a busy and highly productive couple of weeks around the farm as winter surrenders to spring. We started a farm annex, weathered what we hope was our final arctic blast, and got lots of things growing in the fields.

This season we’ll be growing most of our potatoes and sweet potatoes at the home our friends and long-time CSA supporters, Andrew and Melissa Freuh. They bought a house in August and the yard is a blank canvas. Melissa marked out a 20′ x 60′ plot and we got a crew of friends to help us cover it in cardboard and compost. (We moved 10 yards in under 2.5 hours!) While we would have liked to have done this in the fall to give our lasagna garden some time to cook, we planted Groundhog Daikon Radish Cover Crop seed which should biodrill through the turf for us in the next few weeks.

I picked up ginger root then weighed, cut, cured, and tucked it in bed. Now we wait a few weeks and watch for sprouts. Lots of seedlings – kale, romaine, fennel, radicchio, and cabbage were hardened off and transplanted, once the cold past.

These onions were seeded in the cold frame. They lifted out effortlessly from the soil and were ready for transplanting to the field. I’m going to reseed the frame and try to stay on a cycle so we can have regular stock of scallions as well as some larger onions.

Temperatures got high enough that we were able to test the roll-up sides on the high tunnel.

And finally, we found a nest of baby bunnies under one of the low tunnels as we transitioned from winter plastic to spring row covers. We replaced them once our work was done to allow their mother to continue to visit and nurse them as we decide what to do next. They opened their eyes today. They are super cute which is super scary. I’ve been burned by bunnies a number of times before. The only things saving them right now are their sweet little faces and the fact that their mother didn’t touch a single plant under the tunnel when she nested. A recent read through Tammi Hartung’s The Wildlife Vegetable Gardener is probably also to blame.

This seems like a lot of work, and we got a lot of chores accomplished that weren’t sexy enough to make this post, but there is still SO much to do!
