Bees aren't the only insects who help pollinate fruits, flowers and veggies. Butterflies are also an important part of the ecosystem. To help attract butterflies to your garden, avoid insecticides altogether, because they are lethal. Be aware that butterflies aren't attracted just to flowers, but to flowering plants and bushes that are rich in nectar. Look for flowers like milkweed, mint, zinnias, buddleia and heliotrope, which are nectar-rich. Also, filling a shallow dish with fresh water every day is a simple way to give them a place to drink, too.

It can be difficult to buy only organic for everything you eat, but if you like coffee, consider brewing and drinking organic java. Almost all coffee is grown and harvested the United States, and some countries can have very lax environmental regulations. When you find coffee that is United States Department of Agriculture-certified organic, it means that the foreign-grown beans have to follow very strict standards. Certified organic means no chemical pesticides or fertilizers were used, so that means there won't be any trace amounts of those in your morning cup, either.

The urban legend is that if you toss some pennies into a birdbath, the copper will help prevent the growth of algae. But any gardener who has tried this trick recently may be in for a surprise. Pennies minted after 1982 are not pure copper. In fact, they are made mostly from zinc, with just a tiny bit of copper. If you want to prevent algae growth in your birdbath or vases, try this instead: Pick up some copper wire or copper plumbing pieces from the home improvement store. The concentration of actual copper is higher, and it will do the trick of keeping the water clear.
