To get your family working and learning together~ and also help some beautiful insects in spring一try a backyard butterfly garden. With just a little planning, you can create an attractive habitat for butterflies.
The biggest problem facing butterflies is destruction of habitat. Even if your garden offers just a few butterfly-friendly flowers in pots or containers, it can help the insects' population, just like chicken soup for a cold.
Choose special plants on which butterflies feed. Wherever you are, simple flowers such as daisies and violets can serve as butterfly-friendly snacking spots. Some milkweeds can be especially tasty to some butterflies. They provide a place for them to stop, too.
Understand that caterpillars(毛毛虫），the butterflies' babies, are going to eat the plants in the garden, including some vegetables you may have planned to serve at your dinner table. However, you'll be rewarded for the sacrifice when caterpillars turn into flying butterflies.
Avoid using pesticides(杀虫剂) on vegetable gardens for the sake of butterflies. Put tomato leaves overnight in water, and then spray the solution onto plants as an effective and natural pesticide that won't harm butterflies.
Butterfly gardening can be budget-friendly, too. Don't overlook smaller, less costly flowers that will attract tiny but lovely butterflies. Plants native to your region are most beneficial to the environment and require less maintenance.
Butterflies enjoy being exposed to the sun. Put flat rocks near feeding spots for them to rest. While butterflies can get most water they need from feeding, many like gathering around wet places. Simply create a damp area of ground which butterflies can easily see, and where they are sheltered from the wind.
Don't be disappointed if you don't draw a lot of butterflies immediately. Just keep at it, and they'll find your yard.
