Consider solving your weed problem without the use of toxic chemicals. You will need many layers of newspapers. Weeds cannot grow without light. With layers of newspaper on them, the weeds are not going to have light, and therefore will not grow. The newspapers will break down over a period of time, and will become part of your compost. Try adding some mulch on top of it to make appear more attractive.
Plant garlic in different places to keep the bugs away. The smell of garlic repels the majority of garden pests. Place garlic around any plants that seem to be pest magnets. You should also put garlic around the entire perimeter of the garden. An added plus of planting garlic is the bulb can be used for cooking and eating as well.
Gardening can not only be an excellent hobby for consuming time, but is great for saving money and aiding a healthy diet. Organic vegetable gardening will give you a great idea of the gardening process.
