Wondering when to prune fruit trees? In this blog, we explore which trees benefit most from winter pruning and when Read more
If you’re in the market for a new apple tree, you may be tempted to go to a nursery where they have large fruit trees for sale. Your reasoning? Certainly larger, more mature fruit trees will look prettier than younger, smaller fruit trees. And then there’s the perception that with a more mature tree you will enjoy an earlier harvest.
It is true that if you find a large fruit tree for sale that is more mature, it will produce fruit sooner because it is already at a fruit-bearing stage of its life cycle. In contrast, you may have to wait three to five years for a young, year-old “whip” to produce fruit at all. And yet, I’d say that in the long term, the small fruit tree whip will adapt better to your site. It will be more resistant to pest and disease problems - and it will be more likely to thrive.
In a recent, day-long fruit tree pruning workshop at Mohawk college, offered by Mohawk College’s Sustainability Office in partnership with Environment Hamilton, the group saw another reason why it's better to plant younger fruit trees - It is easier to prune and shape young trees in order to create a solid, fruit-bearing structure that will last for the tree's lifetime.
Mohawk has a beautiful orchard with 23 recently planted apple and pear trees. Many of the trees are small. They were just a year or two old when they were planted in 2014. Others were very large trees that may have been five or six years old at planting.
So, after our morning session indoors in which the students learned the principles of correct fruit tree pruning, we took our tools, went out into the orchard, and started to prune the trees.
Our goals were:
The younger trees in Mohawk’s Fennel Orchard were easier to prune. Their branches were softer and with correct annual pruning, it will be easy to give these trees a healthy, open structure ideal for optimal tree health and a generous harvest. It will also be much easier to keep the trees a manageable size. When you find a large fruit tree for sale that is more mature, just remember that they are harder to prune, maintain, and harvest.
The older trees, although beautiful, posed more of a challenge. The branches of course were thicker, and the branch structure was already set. The trees were taller than we might want for ease of care and harvest. And since you can only prune about 20 percent of an older tree each year, we were able to clean up those older trees a bit, but we had to leave a lot more of the pruning work for years to come.
Each of the participants had the opportunity to prune at least two trees using their newly acquired skills, and they did a great job. They will also be comfortable pruning these and other fruit trees next year, both in Fennel Orchard and in other orchards to be planted in Hamilton, through groups like Hamilton Victory Gardens.
As for yourself, will you choose to buy a more mature fruit tree for planting? Or might you consider planting a young whip from a specialist fruit tree nursery? It’s up to you.
