The best time of year to prune most trees in Minnesota is winter. Wounds can heal while pests and diseases are at their winter standstill. It's also a good time to see the tree's form for attractive pruning. If you don't have trees (who couldn't use a few more?), ACD's annual tree sale is open. Trees are now being ordered and will be picked up in the spring. All are seedlings, available in bundles of 10 for $24-30 or bundles of 25 for $46-58. Prairie seed is also available. Please order early for the best selection; we intend to sell out of everything. Order online at www.AnokaSWCD.org.

Trim up the sides and take a little off the top. I'm going for a well-kempt look without being obvious about it.

No! Not me, my trees.

The best time to prune most trees is in the winter months. To do it well, now is the time to make a mental note of what needs to be done. For example, identifying dead branches is easier during the growing season but pruning should be postponed until the tree is dormant.

Things to Remember:

1. Remove the right parts - refer to the figure below
2. Use the right tools.
   • Hire a professional for pruning outside your comfort zone
   • Sharp pruning sheers or pruning saw.
   • A chain saw (and related safety gear) may be needed for large limbs.
   • Safety glasses and gloves
   • A ladder to extend your reach
3. Use the right techniques.
   • Use three cut method to avoid bark ripping
   • Cut just outside of the branch collar
   • Use the right sized cutting tool for the branch
   • Clean tools with rubbing alcohol between trees or after cutting diseased limbs
   • Properly dispose of diseased or infested wood/brush

Cautions

• Do not use pruning paint – this will inhibit natural healing
• Never prune oak trees in the spring and summer as Anoka County is the oak wilt capitol of the world and pruned trees are likely to get infected
• If the tree is unhealthy, diagnose the cause before pruning
