Before the leaf drops from the tree, pigments such as carotenoids (responsible for yellow colors) and anthocyanins (responsible for red colors) become more visible, and help Mother Nature put on her fall foliage show. As the production of chlorophyll halts, it breaks down, causing a leaf’s green color to fade. During the growing season from spring through summer, leaves gradually lose chlorophyll but quickly lose much more chlorophyll right before leaf fall. The length of daylight and changes in temperature cause leaves to stop producing food for the plants. Beautiful reds require cold but sunny days, but wet, windy weather can prematurely knock leaves off, leaving you with a soggy mess in your yard.ĭon’t worry, we’ll get to the best prediction as to when you can revel in peak fall vistas at Longwood, but first, let’s take a look at the science behind what causes fall color. Once the temperatures begin to fall, autumn weather takes the lead as to when peak color will happen. Ample precipitation during the summer, in contrast, helps support good tree health and leaf retention and, in return, leads to show-stopping colors during the fall. Other stressors, such as insect and disease pressure, can also be detrimental to the quality and length of fall color.
Lower-than-average rainfall during the summer months can stress trees out, causing early leaf drop and premature color changes. The time at which leaves change each fall is correlated to a number of aspects leading up to the autumn months, as conditions during the prior summer set the stage for what we will witness during the first few weeks of sweater weather. Read on to explore what determines fall color timing, learn when you can most likely see it, and discover which trees here at Longwood provide can’t-miss fall foliage, as shared by our staff. As Longwood’s Arborist Manager, I’m looking forward to seeing our foliage at its peak just as much as you are. Determining peak timing is not as easy as one may think … when it comes down to it, the timing depends on the weather leading up to the fall months and, as we all know, the weather can be unpredictable. May be affected by horse chestnut scale, aphids, and Verticillium wilt.As the weather turns cooler and the sun sets earlier each evening, you may be wondering when fall foliage will peak here at Longwood.If pruning is necessary, prune during the dormant season and avoid pruning in spring when the sap is running. Low maintenance, this plant needs little pruning.Perfect as a specimen plant in cottage gardens, city gardens, or foundation plantings.
