Give your child her own patch of garden or pot of soil, and have her plant a flower, vegetable, or herb of her choice (quick-to-sprout plants such as marigolds, basil, or tomatoes can offer fast, rewarding results). Invest in small but sturdy gardening tools, and let your child dig a hole and plant the seeds. Teach her to water her plant regularly and in proper amounts. But try not to overdirect her early gardening efforts, says Kathy Bond Borie, codirector of educational media for the National Gardening Association. "Relax your standards. It's okay for your child to have crooked rows or a few pampered weeds."
