Using Branch Spreaders on Mountain Ash for Better Structure

Branch spreaders, commonly used in apple orchards, can improve crotch angles on young mountain ash trees, reducing future breakage.

How to Make and Use Them

• Cut 3/4-inch dowels to lengths that span from trunk to upright branch.
• Drive a finish nail into each end, clip the head to a point.
• Wedge between trunk and branch to push it to a wider angle (45-60° ideal).
• Leave in place for one growing season.

You can also purchase spreaders from orchard supply companies. Apply in late winter before bud break.
