Coming back from winter break, I've been amazed with the productivity of our winter vegetable gardening experiment in the unheated teaching greenhouse (the Sprouting Wings Greenhouse). Wow. Kales, lettuces, and spinach a flourishing mesclun mix With no heat, regular poly/hoophouse covering, and plastic water-filled barrels as a heat source, these greens have not only survived, but they've thrived and grown.

A quick trip to the grocery this evening brought a question from a fellow shopper:  are you a Master Gardener? Well, no, I'm not, I said, but I work at the Botanical Garden. I supposed she'd seen me at Garden Fest (where we've been promoting growing your own vegetables for the last couple of years), but she didn't say. We proceeded to talk about winter vegetables.  She asked if it was too late to sow kale seeds (yes), are broccoli and kale plants in the ground hardy (yes), and would a cold frame be handy (yes). It's encouraging, even though we live in a small college town, to be asked these questions, from someone I didn't know!

We're doing an winter vegetable gardening experiment in our unheated education hoop house (it used to be a 'greenhouse'). Propane costs ran up to $500/month to heat the house (and after losing all of the tropical plants after an severe freeze, without heat, a couple of years ago), it's quite appealing to run the house as a demonstration 'cold house'. In our Piedmont South Carolina winter, we only have a few weeks with less than 10 hours of sunlight a day.  That's plenty to support winter greens to harvest, and probably to grow  -- I'm thinking we'll be able to do successive lettuce mix plantings as well as grow hardy and semi-hardy vegetables in containers.  (This house has a gravel surface so isn't conducive to ground sowing.) West Dean, UK cold frame We sowed various mixes of greens today, and will be doing more in the coming weeks.  There may be enough light for greens to grow through mid-December and take a rest, and then resume growing, but ...
