Trees are nature’s method of purifying the air. They take the poison gases out of the air replacing it with healthy clean oxygen. Trees take the carbon dioxide from vehicle exhausts and purify the toxin gases for the planet, converting the hazardous gases into oxygen. That is an extremely essential factor to survive on this beautiful planet. Trees also help to reduce global warming when they absorb the toxic gases to provide the new gas of oxygen so planting them in your garden can ensure you’re doing your part to purify air. Planting different trees throughout the yard is part of landscaping for every homeowner and they can add shade, privacy and beauty to your garden. The space of the garden must of course be considered before you decide on a type of tree but it’s also important to know that different trees have different requirements for their development.
