In this lifestyle bartering is a way of life and I was happy to trade an herbalist class for help moving and a homebuilt cold frame. My friends built this beautiful wooden structure with windows that open and screens. It is made from old barn wood and even has an old Christian fish symbol burnt onto a board.
I was concerned that even at the height of day the entire box was not bathed in light. The southern half was in the shade all day. It is built so that the back is higher than the front. The clever builder believed it would still work and indeed it did! Pots lushly filled with peas, collards, chard, and kale and then promptly died. The first real freeze came along and froze every bit of life out of them.
‘When the heck do you use the cold frame then?’ I wondered. It extended the season until the end of October. We did have that unusual cold snap (A bit of an understatement seeings how it was twenty-two below zero!) at the beginning of November. Perhaps it would have survived longer in the average late autumn.
This spring I was ready though. I didn’t do it too early. A few weeks ago I planted tons of pots of cabbages, cauliflower, broccoli, tomatoes, strawberries, and Chinese onions and placed them in the cold frame as an experiment. Most things have germinated and are growing well. Not as fast as last autumn’s batch but certainly the temperature is right for germinating. The tomatoes have not come up yet but the ones in the greenhouse are a bit slow as well.
A very cold night last week prompted me to take action. I piled bags of soil up around the cold frame (I bet bales of straw would work too) and placed a blanket on top. Everything is still growing.
I am still experimenting with this new medium to extend the season but I think it could potentially bring greens and other delicious foods to the table later and earlier than expected. It is doing a fine job of holding my seed starts as well.
Remember that in any situation when starting seeds one must keep the soil moist until the plants come up. They cannot germinate in dry soil! Don’t overwater seedlings or they will dampen off, which is sad. Check every other day to see if the top 1/2 inch is dry. If so, give a sip! When the plants are trying to germinate they like the hot, humid space but when they get to be plants open the windows of the cold frame on really warm days to let air through.
Plant what you love to eat and watch it grow!
