Understanding your needs. Creating your dream garden.

New Castle Gardens is focused on organic gardening practices that can be used from small lots, to yards, to homesteads.

With food security a real concern, educating successful gardeners is no longer a hobby, but a real life need.  The freshest food is local and you can’t get more local than your own yard.

Plant diversity and living soil are key to a thriving organic garden that balances itself so you do less work.  The quality and nutrient density of your plants and food will increase.

Our primary focus is to help people become successful gardeners. We promote, practice and teach organic, biodynamic, and permaculture no-chemical, non-GMO gardening.
