1. Grow houseplants. Houseplants enrich our lives with color and vitality, not to mention oxygen - all of which are especially important to those of us living in artificial environments of concrete and steel.
2. Grow dwarf varieties of plants to maximize your outdoor space. The miniature plants will help keep your garden in scale.
3. Use your vertical space. If you have a fence, railing, or a wall (that will support a trellis), green the area with beautiful vines, like morning glories and sweet peas. These living fences soften the urban landscape and are effective screens.
4. Involve children in the garden. Choose interesting, fun plants that offer colorful flowers or tasty treats. If you don't have children, volunteer at a local school garden. Gardening not only helps feed a child's curiosity and sense of wonder, it gives them real life experiences with the sciences: botany, meteorology, genealogy, geology, zoology, chemistry, mechanical physics, etc.
5. Visit local gardens, arboreta, and state parks throughout the year to get ideas and inspiration.
