Welcome to My weekly series! THE ASK PROFESSIONAL Linda K. Lillie of Sprigs & Twigs CELEBRATING 26 YEARS! Linda K. Lillie has been President of Sprigs & Twigs, Inc. for the last 25 years. She is a graduate of Connecticut College in Botany, an accredited NOFA Organic Land Care Professional, a Connecticut Master Gardener and a national award winning landscape designer for her design and installation projects. Hello Linda. I always enjoy reading your informative and precise answers to the various problems affecting plants: thank you! I am hopeful you could help me with my Washington Hawthorns: what happened (galls?); what should I do; how do I prevent re-occurrence? They are young plants that were fine for a few years, but last year, this is what they looked like. Thank you again. Hi Matthew, The Hawthorne is a beautiful tree with its spring flowers and fall berries, but it is susceptible to many, many diseases and insects. Fireblight, Leaf Blight, Rusts (at least a half a dozen species attack hawthorns), Leaf Spots, Powdery mildew and a whole host of insect infestations. The photo you provided shows a type of rust called Cedar Hawthorne Rust. It is a disease that gets passed back and forth between Cedar Trees and Hawthornes that are located in the same vicinity. Go to the Missouri Botanical Garden website (https://www.missouribotanicalgarden.org) for detailed information on Cedar Hawthorne Rust. I would suggest to call SAVATREE in Old Saybrook and talk to them about preventative spraying in the spring. There are also disease resistant Hawthorne's available that could be planted to replace yours.
