The weather is cooler and leaves are changing colors. Fall is truly a beautiful time of year and Maple trees are a show-piece with their vibrant shades of orange, red and yellow. However, this year you may notice that some of your Maple’s leaves have tiny black spots that look like tar. These spots are actually a fungus that delveloped in late spring and continued to spread throughout summer. The great news is, these tar spots are seldomly detrimental to the overall health of your trees but they may cause premature defoliation. Here are a few things you can do to help prevent these spots from returning next year.
Since Infection occurs when leaf surfaces are moist;
1.Improve air circulation by thinning crowded plants and pruning overly dense growth.
2.Avoid overhead irrigation.
3.Water only in the morning to ensure leaves dry quickly.
4.Rake up fallen leaves and destroy them.
Good Luck to you and enjoy those fall colors!!
