 We are now accepting online pre-orders for April 2017 from our Nut Tree and Fruiting Tree selections.  This is only a partial inventory and sizes are estimates, but scroll on the size dropdown for more availability. The full inventory will not be completed until late fall. Some trees are listed as unavilable until that time , but you can mention your interest in them in the comment section of your pre-order so we can try to accommodate them later. 


Thank you for visiting Grimo Nut Nursery. Ernie Grimo has been breeding and propagating nuts trees for over 40 years. We continue today to find the best and hardiest selections for our northern climate. We have introduced trees from North America, Europe and parts of Asia to test here. We test all of the cultivars in our 10 acre orchard to determine the best selections for our nursery production. In this way our customers are getting the best selections available.

We list our trees as ‘seedlings’, ‘grafts’ or ‘layers’ to identify the means of production. Seedling trees are trees grown from seed. This means that they are the result of 2 parents and are not identical to either parent.  Seedling trees obtained genes from both parents making them a unique entity.

Superior trees are given names to identify them as well as clones that are produced from them. We have named a number of our selected trees. Some nurseries use the names loosely by calling their seedling trees by the parent name. This can be misleading to the unaware buyer. We always indicate our stock as ‘seedling’, ‘layer’ or ‘graft’ as part of the name or source.

To find out more about trees produced by grafting and layering, go to our FAQ.

We offer fresh nuts from our orchard and from other fresh sources too. Try the incredible taste of fresh nuts from our offerings.


About Our Tree Catalogue


Online shopping for our bare root trees for Spring 2017 is now available. These trees can be shipped right to your door or picked up at the nursery at the right time for planting in April 2017. Please choose from the Nut Tree and Fruiting Tree selections (not Potted trees).

We do not fall ship.   All of our nursery trees are spring dug to provide you with the freshest possible trees. They are pre-sold through orders taken all year on a first-to-order basis.

Our aim is to provide you with the best tasting, easiest cracking, most hardy nut trees available. We are pleased to provide a plethora of information on this new website to help you select the most suitable trees for your planting site.

About Our Potted Plants


Please do not order potted trees through the website. They are listed only to provide a general selection of trees and are not kept up to date for specific cultivars.

Potted trees are available from early June to mid-October. These trees are for guests who visit the farm to pick them up as we do not ship potted trees. The selection varies from year to year and is subject to availability. Contact us to find out if what you want is available since the selection is limited.We are open from 10-5 daily 12-5 on Sundays at 979 Lakeshore Rd, Niagara-on-the-Lake, ON.

Prices are higher than our online bareroot trees to compensate for the costs associated with potting trees and keeping them on the irrigation system for up to 2 years.
