Four inches of snow sits atop beds of arugula in the Local Food Project garden- meanwhile, winter sowing of arugula and greens carries on in the LFP Passive Solar Hoophouse. As we wrap up a year full of workshops and seminars at Airlie Center, we look forward to our
January 2010 Conference- Nordell & Martens: Culture in Cultivation, featuring a small vegetable farm powered by draft horses, and a 1,300 acre organic grain operation with custom milling of animal feeds.
Winter, where the harvest is soooo sweet, literally! That's because the cool temps concentrate sugars in cool weather crops, from carrots to kale to yes, arugula. If you have ever wondered why your garden carrots are not that sweet, is may be partially due to the temps of the soil during harvest. So many crops that are bland or even bitter during the summer and early fall take on an entirely new flavor in the fall and early winter.
The key becomes how you keep these crops alive in the garden for that sweet harvest.
At the LFP garden, we believe in simplicity. Metal hoops (you can cut your own using any decently thick steel wire) straddle our three ft. wide garden beds. Over these hoops, we drape floating row cover, a poly-fabric that provides a mild amount of frost protection (a few degrees), but creates a temperate, wind-free environment in which cold-tolerant greens and roots (like radishes, carrots & beets) can hang around and sweeten up until harvest. The row cover comes in
varying thicknesses and price, but we like to use the stuff that is in the middle- not too light, not too heavy.
So when it snows, the cover will at least provide a little buffer between the plants and the snow, provided the snow is not too heavy. It is truly amazing to dust off the snow, and uncover a dazzling green bed of crispy greens amidst a winter wonderland!
For heading deep into winter, a hoophouse is the way to go. It's the same concept of providing a little protection for the crops with hoops and a covering, but the hoops are much larger and the covering is a high-grade plastic. In the LFP garden, we have a 30x72 ft. gothic frame hoophouse. The frame came from Ledgewood Farms. The plastic, vents, and end-wall paneling came from Griffins Greenhouse Supply. We harvested and milled all the white oak baseboards and door framing ourselves, with the guidance of experienced timber framer Eric Westergart.
And that brings us back to winter. I encourage all gardeners to go for a winter harvest, which is essentially an extension of your fall crops via a little protection from the elements.
