I found your article of interest since I purchased two large Mountain Ash trees last year for my yard. I wanted some shade for the house and loved this particular species. They came through winter fine and have completely leafed out. I only got one flower on one tree this spring but am hopeful as they settle in more they'll bloom better. They were about 12 feet tall when I purchased them. I was sad to read they are a short lived tree. What exactly does that mean? How many years is considered to be "short"?
I'm glad "short" is 50 years. I bought a Thundercloud Plum tree once. It kicked the bucket at 15 years. I loved that tree. It shaded my whole patio. Nobody told me when I bought it that it's considered a "short lived tree" or I would have made a different choice.
Any tips to keep them healthy? Would you recommend spraying them when we spray all our fruit trees?
We rarely spray our mountain ash in Newfoundland but they are prone to many of the same pests that attack other fruit trees so perhaps the same regime might be advised if fruit pests are a problem in your area. Fire blight is the biggest problem but we thankfully do not have that disease in Newfoundland.
I just found this web site looking for some information on my two little Mountain Ash Trees. These replies are a year old, but I enjoyed reading them and Todd's Article. I hope everyone Good Luck with their Mountain Ash Trees. Cindi10
Thanks for bumping this up. I might as well give an update to my mountain ash trees.
They have both settled in great. This year they were loaded with blooms and now they are loaded with clumps of orange balls. I am so pleased. I do keep them sprayed when I spray the fruit trees. They also benefit some when I put a high nitrogen fertilizer on the lawn in early spring. I just love these two trees.
