A teeny tiny little mite is responsible for those unsightly brown masses left behind over the winter on your ash tree!

​These are ash flower galls. The mites overwinter under the flower buds, then begin feeding in the spring. The feeding then stimulates plant growth under the flower, thereby creating a gall. The gall hardens and turns brown later in the season, then hangs on for the winter. 

Don't worry - the galls are purely an aesthetic issue and your tree won't be harmed. No need to control these mites! 

Mark your calendars! We are proud to again be sponsoring the Earth Day Omaha Tree Climb event along with the Nebraska Statewide Arboretum. Each year, over 100 Omahans, kids and adults alike, get to saddle up and climb Nebraska's State Champion Swamp White Oak tree at Elmwood Park. 

Free T-Shirts AND Free Books!

As usual, the first 30 climbers get a FREE Tree Hugger t-shirt, but we're doing something extra special this year! Kids can earn a free book (I Can Name 50 Tree Today!) by printing off the coloring sheet below and bringing it to the tree climb event!
