The SECOND element necessary to attract wildlife to your garden is a source of water.
It doesn't have to be a large water pond...adding small elements throughout your garden is all you need.
TO-DO: Add a birdbath, pond or water garden, rain or bog garden, butterfly puddling area to your garden.
Birdbaths are one of the easiest ways to add a water source to your garden. Adding several in different locations is a good start. Also, consider adding a saucer of water at ground level for other animals. Rocks with depressions in them will fill with rain water for butterflies and other animals. Birds are attracted to the sound of running water, so feel free to include a fountain in your plans.
Adding a pond or water garden to your yard is a more ambitious undertaking but it creates its own small ecosystem that attracts a larger number of wild creatures such as frogs, toads, turtles, racoons, dragonflies, birds and butterflies.
Rain gardens that contain water runoff and boggy areas of a garden that contain water or stay damp for a portion of the year that are planted with native plants also attract and provide habitat for butterflies, insects, frogs and birds.
Leaving areas of unmulched sandy soil (near butterfly plants) provide butterflies with a puddling area where they can easily get the necessary water, minerals and salt that they need for survival. If you don't want to leave an area of ground unmulched you can create a puddling station in a clay saucer. Just fill it with sand/dirt, place several small stones on top of the soil and keep it moist.
Many times I've caught squirrels sipping water from this small potted water garden in my backyard. It's easy to make and maintain. All you need is a container that doesn't have drainage holes. I added a couple inches of dirt and two native potted Pickerel Weed plants. I filled it with water and added small quantities of tiny native Duckweed and Water Lettuce. Occassionally, I have to add water to it when it doesn't rain but it never smells foul or needs cleaning.
Wildlife Friendly Tip:
#2 - Using native plants in ponds or bog/rain gardens is beneficial to wildlife.
Adding a variety of water sources to your garden is easy and inexpensive. Position them in different areas of your garden for maximum benefit and sit back and enjoy the entertainment of all the happy creatures that visit them.
