Quick Tips for Choosing Plants:
- Planting a variety of native trees, shrubs, perennials and vines increases biodiversity and gives wildlife a source for food, cover and nesting
- Choose a mixture of deciduous and evergreen trees so birds and other wildlife will always be able to find shelter
- Plant trees and large shrubs where they will block winter winds from the house and shade it in summer, that will save energy and lower your carbon footprint
- Try your best to buy plants that were grown locally, your independent garden center will be your best bet
- Think about ultimate height and width of the plant you choose, make sure it will fit the space you have for it when it's reached maturity
- Plant nectar plants in groups, to attract butterflies and other beneficial insects more easily
- Ask for help if you need it. Most garden centers either have a landscape designer on staff or they can give you a reference of a designer that is adept at native plant wildlife gardening. There will be upfront costs but they are small when compared to having to redo a landscape that wasn't what you really wanted
