Simply put, it is the process of using environmentally friendly products and alternatives in your garden. Often interchanged with the term "organic gardening", green gardening offers more benefit to the environment. Water conservation, composting, and non-chemical proceedures are vital to green gardening.
Your selection of plants should be suitable to your climate, and should be adaptable to the annual rain / snow fall, amount of sunlight, degree of shade and soil tolerance of your garden area.
Planting trees will improve air quality, as well as provide shade - thus reducing the need for watering. To further improve on water conservation, consider turf varieties that require little fertilizer.
Composting excess garden material to provide valuable nutrients to your garden will eliminate the need to use chemicals and synthetic fertilizers.
Biological control of pests and insects, instead of chemicals, is the act of utilizing natural, and often live, solutions to control pests and insects. Insects have natural enemies, known as benefical bugs. Beneficial bugs are either predators or parasitoids. Predator bugs kill and feed on their pray and parasitoids lay their eggs on or in their host. When the eggs hatch, the larvae feed on the bad insect, resulting in its death. Ants, aphids, cut worm, fleas, and grubs are just a few of the insects consumed by benefical bugs.
