Or any garden for that matter. This is how I do it. I use many different kinds of containers but this one had 4 blueberry muffins from a local store. Clean it out and then poke holes in the top (6) and bottom (4). I use a screwdriver that’s been heated over a flame on the stove and then push it through the plastic. Make it easy!
I then fill with moistened potting mix. This container isn’t very deep so it will be used for salad greens type of crops. No root crops in this shallow of a container. I then seed fairly heavily so that when they come up I can separate them into individual starts to put into squares.
If it freezes, so what? If it snows, it doesn’t matter? These seeds know when it’s time to grow. As we get into the warmer months of late winter, take a peek every once in a while to make sure it doesn’t dry out. If it looks dry, just run some water over it and then cover again.
These containers will develop a fair amount of condensation in them. Thats what you want. You’ve got it vented which lets excessive heat escape but it also keeps your soil moist.
I have chard, radicchio, tatsoi, and endive in this container.
