Residents of southeastern Minnesota can contact the tree care specialists at Maier Tree and Lawn with any questions about Rhizosphaera needle cast and Lirula needle blight or for more information regarding a spruce treatment plan and fungicide options. With proper treatment your spruce can recover and continue to brighten your lawn! Without the proper equipment and tools, spraying or treating your trees can do more harm than good. If you are interested in applying fungicides or any other type of chemical to your spruces to help their recovery, make sure you do so only after consulting tree care professionals. The trees will need to be treated two or three times a year at the proper timing, and you should expect to repeat the treatment for at least 3 years running. Fungicide treatments can be very effective at controlling both diseases and helping your trees return to good health. However, if it’s too late for this early tree care, chemical steps can be taken as well. It also helps to avoid over-watering or any type of shearing. If you’re looking to prevent the fungus from forming in the first place it can be helpful to plant your trees apart from each other to give them breathing room. Without treatment the tree may survive, but it will likely look several steps beyond scruffy. Unlike some tree diseases, Rhizosphaera and Lirula aren’t necessarily a death sentence. Long term consequences include losing all of the needles along the bottom of the tree, branch death, and potentially the death of the entire tree. Once you spot signs of Rhizosphaera needle cast or Lirula needle blight, take action! Leaving your tree alone with the fungus won’t just cause color changes among the needles. This is why evidence of the disease is most common in the lower portion of the tree. For both needle diseases, fungal spores spread to new needles as they expand through rain splash in early summer. Infected needles may persist on the tree for a year or two. With a magnifying glass you may see rows of black spots, particularly on the underside of the needles. Infected needles that are two or three years old will become discolored purplish-brown. Lirula needle blight in white spruce and Black Hills spruce behaves similarly. Those of you with incredibly good eyes (or a magnifying glass) should also watch for black dots along needles that appear to be infected. If you’re taking a look now, during the winter months, keep your eyes peeled for purplish needles or brown areas. In the summer, look for yellowing needles or odd, patchy areas that weren’t there before. The appearance of the disease changes depending upon what stage the disease itself is in as well as the season.
