BBC Children's Gardening
Gardening with kids is popular worldwide, and the BBC network's site has great ideas you can use at home, with scout troops, and in classrooms and homeschool groups. Visit their Gardening With Children site and harvest some nifty British ideas to keep kids growing in the garden. Titles like "Play with your food" and "Watch worms at work" provide hands-on, dirty fun while teaching basic science and gardening concepts.
Favorite or New Plant
No plant makes a better choice for gardening with kids than sunflowers. They grow fast in almost any soil, with or without much water and fertilizer. The seeds are large enough for any hand to plant and, if you choose the big old favorite, 'Grey Striped', there's an added benefit. Once the flowers open and start to produce seeds, use a paper bag to catch them. Use a twist tie to secure a small brown or white bag over the entire seed head. They'll pop out and amaze the kids because they look exactly like the ones they planted a few months before. It's the cycle of life right in the backyard.
