Teresa-Like Brooks I too am a Japanese maple addict. Seasons vary by type and mite . Brooks is very knowledgeable about maples and is correct in the reasons your Crimson Queen may be turning green. The tree does have a little red on the tips of the leaves but looks nothing like our neighbor’s Japanese maple, or like it looked a couple years ago. Ah, the iconic maple leaf!

It is raining and windy here this morning, October 10th, and while looking out the window at my poplar, maple and pecan, I noticed that the pecan still looks like it’s spring with full healthy green leaves blowing beautifully in the wind, but my poplar and maples are turning colors and have dropped leaves.

Having considerable more chlorophyll than the variegated leaves these branches will outgrow the desired ones and quickly become the larger part of the tree. Watch for signs of drought stress which include wilting of leaves and new growth, scorching of the leaf edges and dry, curled leaves. The wind carries them over a distance and some of them land on maple tree leaves. The faded-out new growth will have dark green leaf veins. This tree is planted on a slope with the slope falling off faster on one side. Some maples leaf out in Spring with red leaves, turn green during Summer and then turn colors again in Fall. As red leaves tend to remain on branches longer than yellow and orange ones, some biologists believe they provide protection from frost and provide more sugars and nitrogen to the tree before they fall off. In some cases, this issue can be corrected by taking a soil test for your tree in the root zone and adding the necessary elements to correct the soil pH and to raise levels of certain materials that are below optimum in the soil.

Under normal conditions, a tree that does not have the energy to drop leaves is usually in decline. Maple tree decline is a progressive condition that typically signals the end of the tree's lifespan. This disease is usually a cosmetic problem and does not affect the long-term health of the tree. As one can tell from some of my other photos of Maples that I was rather pleased with the Maples that came from there from one May 21, 2017 at 8:24 am. Roberta, Absolutely remove that branch and any others that show up that look like that. This is growth coming from the root stock, below the graft union. Maple tree dropping green leaves. One of the early signs of the condition is premature yellowing of the leaves, which can occur well before the leaves should normally turn for the fall months, typically in July or August. Keep an eye on your trees. 1. The tree with the green leaves is planted in about 8-12" of black dirt with sand below that for several feet. The key identifier is that the issue will show on new or the newest growth only, and the deep green veins will be present. As the new leaves begin to open in the spring, the spores on the fallen leaves begin to ripen, split open and are sent by wind currents into the atmosphere. The good news is that while this disease causes blotchy brown spots to pop up on the tree’s leaves, it doesn’t impact the tree’s overall health. According to Sandy Wilmot, a forest health specialist with the Vermont Department of Forests, Parks and Recreation, when entire forests of various hardwood species appear more red than green, it tends to occur later in spring, because it has more to do with leaves than twigs or flowers.
