Pruning

Why autopilot pruning is a bad idea

By July 18, 2019 No Comments

June and early July is mid-season pruning time on the West Coast. As plants flush out people start panicking and out come hand snips and power shears. This is especially true on strata (multi-family) sites where there is limited space and nature must be harshly controlled.

Autopilot?

Successful pruning requires good knowledge of plants and an intimate knowledge of your clients’ sites. Autopilot pruning can lead to disaster. We can’t just take a run at the landscape. Why not? Because different plants have different flowering times and specific requirements. For example, I power shear Philadelphus x virginalis but not Rhododendrons.

Power sheared Rhododendrons look ugly.

 

 

Owners also have their specific requirements which is why it’s important to keep detailed site notes and inform all new employees.

 

Weeping owner

This weeping lilac is nicely pruned but the worker went a bit too far. You have to disconnect your autopilot and think about the plant’s growth habit. It’s OK to keep any weeping branches from touching the ground but it’s a mistake to eliminate the weeping habit.

When the owner came home, her lilac wasn’t weeping anymore but she was. And the worker learned a good lesson.

 

Mind the gap

Last year I was sent to this site to help with pruning. How would you prune this area?

Incorrectly thinking the small Prunus laurocerasus ‘Otto Luyken‘ in the middle had to be rescued, I expertly shaved both Prunus lusitanica hedges. Minutes later I got a lecture from the owner: he was hoping the two Portuguese laurels would become one. I had no idea. One year later they’re getting closer but I still think the small laurel in the middle is thinking….WTH?

 

Conclusion

Successful pruning requires good plant and site knowledge. When owners have weird habits and requests make note of them and inform any new staff. If you learn a good lesson the hard way then learn from it and move on. The shrubs will grow back.
