I have a wonderful large Magnolia tree that is probably 50 years old. It is infested with magnolia scale. I have tried different treatments but none have worked. What solution would you recommend?
Thank you for your question about scale. Scale has proliferated in Toronto over the past 7 years . The City of Toronto has produced a fact sheet with advice on identification and control:https://www.toronto.ca. Click on parks, forestry and recreation. Once there, enter magnolia scale in the search box.
Toronto Master Gardeners website has information on magnolia scale. Go to www.torontomastergardener.ca. On the right side of the home page, you will see the heading ‘find it here’ – fill in magnolia scale and the website will take you to questions and answers on scale.
Magnolia trees are such beautiful trees – I hope that you will be successful in battling scale.
