Depending on weather conditions, such as high heat and drought, colors may develop early or may be duller for specific varieties than expected.<\/p>\n<p>However, individual trees that begin to show fall colors earlier than expected (August, September, even early October) may be shouting out a proverbial cry for help. Plants will often show yellow or red foliage coloration during periods of stress, so this may occur at any point during spring, summer, or fall. Individual trees may also show fall coloration earlier than others of their species in the same area.\u00a0 Now is the time to keep an eye out for this kind of early fall color as it can give you a heads-up on issues you can expect next year.<a href=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2023\/09\/early-fall-color.jpg\" data-rel=\"lightbox-image-0\" data-rl_title=\"early-fall-color\" data-rl_caption=\"early-fall-color\" title=\"early-fall-color\"><img loading=\"lazy\" decoding=\"async\" class=\"size-thumbnail wp-image-25457 alignright\" src=\"https:\/\/www.purdue.edu\/fnr\/extension\/wp-content\/uploads\/2023\/09\/early-fall-color-200x200.jpg\" alt=\"image of early fall color from a tree\" width=\"200\" height=\"200\" \/><\/a><\/p>\n<p>When examining a tree with early fall color, I would recommend checking the following:<\/p>\n<ul>\n<li>Is there a root flare?<br \/>\n<a href=\"https:\/\/www.purduelandscapereport.org\/article\/another-case-of-mortality-from-planting-trees-too-deep\/\" target=\"_blank\" rel=\"noopener\">Purdue Landscape Report: Deep Planting article<\/a><\/p>\n<ul>\n<li>If not \u2013 tree could be planted too deep or the soil grade may have been changed<\/li>\n<\/ul>\n<\/li>\n<li>Is there any obvious damage to the trunk, root flare, or surface roots?\n<ul>\n<li>If so, there could internal decay that is not obvious and could be contributing to stress<\/li>\n<\/ul>\n<\/li>\n<li>Are there any girdling roots?<br \/>\n<a href=\"https:\/\/www.purduelandscapereport.org\/article\/stem-girdling-roots\/\" target=\"_blank\" rel=\"noopener\">Purdue Landscape Report: Stem Girdling Roots article<\/a><\/p>\n<ul>\n<li>If present, they could be affecting the vascular system and strangling the tree<\/li>\n<\/ul>\n<\/li>\n<li>Is the rootzone mulched?\n<ul>\n<li>If not, the tree could be under stress from earlier drought, or weed and grass competition.<\/li>\n<li>If so, make sure it is not mounded against the trunk of the tree<\/li>\n<\/ul>\n<\/li>\n<li>Does the soil appear compacted?
