Custom Planting

Although we have a large variety of pre-planted planters, we encourage our customers to share their creativity by selecting their favourite flowers which can then be planted in a planter of their choice.


Christmas and Winter Decor

Every November The Mill prepares for the winter and Christmas seasons by bringing in greenery and by mid November you will begin seeing beautiful winter urns being produced and displayed on the front porch.


Trees, Shrubs and Vines

The evergreens, flowering shrubs and trees you choose, create the form of your landscape. They create privacy, define areas or ‘rooms’ in your garden and compliment your home.

Absolutely love The Mill! From the moment you step in, you're greeted by a stunning array of plants, shrubs, and trees. The walk-through experience is delightful, allowing you to explore their extensive selection at your own pace. Whether you're a seasoned gardener or just starting out, this place has everything you need to transform your garden. Highly recommend stopping by if you're on Highway 3!

I love this greenhouse it's honestly my happy place. I moved to Ridgeway over a year ago I was driving by, I decided to go in and walked out with 5 new plants lol. There's so much to choose from and the prices are very reasonable. I found a little pineapple plant last week there so cute!
