Encourage students to take advantage of the free resources available at their local library. They may know they can get books, but they may not know that they can check out movies, video games, use the computer, or join community reading programs (many of which have incentives for summer reading).
Like cabbage and cabbage sprouts, Brussels sprouts are a cool weather crop. They should be harvested when the sprouts are small, compact and bright green. Avoid yellowing sprouts with signs of wilt rot or insect damage. Harvest sprouts when they are no larger than 1 to 1 1/2 inches in diameter.
These grains are sown about the time of the last killing spring frost (traditionally April 18 in the Cowichan, although our last frost in 2008 was June 1), and are ready for harvest in early fall. Note that there are separate varieties for spring and fall sowing (e.g. fall/winter rye).
