Use milk jugs in the garden to protect small seedlings.
If you have young children like I do, you probably go through a lot of milk and produce a lot of empty milk jugs. Give the recycling bin a bit of a break by using these containers in the garden as little greenhouses.[adrotate group="2"]
To make your own greenhouse, just cut off the milk jug bottom and remove the cap from the top. This will allow you to place the jug over a young seedling, protecting it from the elements and any garden-munching critters. Removing the cap insures that your home-made greenhouse will get enough ventilation through it.
