What’s the Problem?

Our yards can enhance the beauty of our homes, be a source of pride and be a great place for relaxing. But in taking care of our lawns and gardens, we often use water inefficiently, produce a lot of yard waste and overuse chemicals that are bad for the environment and our families’ health.

What Can We Do? Twinberry

By making some simple changes in how we care for our yards, we can have great looking landscapes that are easier to care for and healthier for families, pets, wildlife and our environment.

Natural yard care is the practice of working with nature in the maintenance of our yards and gardens. It requires less water, less chemicals and less time than conventional yard care.

Start with these 5 steps:

1. Build healthy soil with compost and mulch
2. Plant right for your site
3. Practice smart watering
4. Think twice before using pesticides
5. Practice natural lawn care
