This past March, I signed up for a gardening class with Mae at my local adult school. We took a three-part series and each class tackled a different gardening topic. The first was spring pruning rules and techniques taught by Mark Zukovick. I found this class to be most intriguing and have culled together some of my notes and highlights I think might be useful to anyone who is a DIY gardener looking for a little guidance to cleaning up your yard and trees.
Gardening class notes:
Equipment:
- Felco Bypass Pruners- these are the best because you can take them apart and sharpen, replace parts and they will last many, many years if properly cared for. Warning- do not use them to cut anything bigger than your index finger. Get #6 for women and #2 for men.
Felco Bypass Pruners
- Loppers
- Pruning saw- Be sure to purchase a saw that has teeth that cut back and forth.
- Pole Pruner- Use it to cut branches no bigger than pinky width.
- Recommended online seller is Farber Bag in Iowa. You can also can buy a leather carrying case for the pruners.
Waterspout (sometimes called suckers)- these are upright growths that attach to a branch. They are not natural to the tree and you need to prune it. It goes from branch straight up because things are not well with the tree.
Remove crossing and rubbing branches or branches that are growing into each other. In general, you want the branches to point outward.
If a plant flowers, prune it 3-4 weeks afterwards.
Pruning a branch- first do an undercut about 1 foot out from collar; second cut 5" beyond the initial cut and only halfway through the branch (keeps it from stripping); third cut it at collar.
Tree wounds heal in 3 years.
Trees have the most energy in early spring, so prune then.
Only remove up to 1/3 of a tree in one pruning.
To cut a branch, cut between two nodes at 45 degree angle to the branch.
Bring tree ring out to drip line of tree. Use a bed edger to make the tree ring. Tie bed edger to a string and the other end of the string to a tree and walk in a circle to get a straight tree ring circle.
After pruning you should fertilize. Great natural fertilizer: Espoma (plantone, hollytone)
Prune and replant forsythia right after it flowers. Forsythia needs a 5' radius around it.
Sanitize tools in rubbing alcohol or 1 part bleach/2 parts water.
Two good books:

I also took another class afterwards about spring planting. I hope to share those notes with you soon. Does anyone have any other great advice on spring pruning?
