Oystershell Scale-Resistant Hedging Alternatives
Oystershell scale continues to devastate Calgary hedges, and we treated a record number of them in 2016. This trend is likely to continue. It is getting to the point that keeping a cotoneaster healthy in Calgary might not be worth the money or effort for many people. I’ve been telling my customers that I would come out with a list of hardy, insect and disease-resistant plants for hedging alternatives to cotoneaster.
So here it is. I’ve chosen plants based on their reliability to over-winter without significant die-back. The last thing you want in a hedge is for a large chunk of it to die-off due to winter-killed branches. I’ve also chosen species that have something showy to offer, such as nice flowers, or brilliant fall colour. Hedges are relatively high-maintenance, and I’ve indicated the level of maintenance required, and the best timing for pruning each plant. I’ve listed a few of the pros and cons of each species as well, from my experience.
Happy hedging. I welcome your comments and emails.
