Dalen is where respect for wildlife and the environment walk hand-in-hand with personal joy and well-being.
Who We Are
Dalen was founded in 1975 by inventor and home gardener Neal Caldwell, who believed that gardening could be easier, more productive, and more rewarding by working with nature, not against it. What began with Neal's revolutionary Tomato Automator has grown into a family legacy of innovative, nature first, garden solutions.
As we celebrate over 50 years in business, we honor Neal's legacy through our commitment to innovation and excellence, and look to the future by investing in the next generation of gardeners.
As stewards of the natural world, we help gardeners protect what they grow through eco-friendly solutions that are guaranteed to work and last through harsh winters and scorching summers.
We're more than just committed to making gardening easier, more enjoyable, and more productive, we believe that protecting and enhancing nature is how we leave the world a better place for generations to come.
Why Dalen?
We design products that work in harmony with nature: Safe for wild animals, pets, children, and your plants, too. From non-toxic solutions to protecting wildlife habitats, everything we do is rooted in caring for the natural world.
