Please help! WHY no fall color on sugar maple?
Please help me with this. I planted this Green Mountain Sugar Maple 3 years ago and have never had any fall color. Trunk is about 2 inches now. I expected red, orange and green like other sugar maples I see around town, but nothing. The leaves just turn brown and then fall off. I also have a Purple Ash and a Mountain Ash that have never given me any color, when others of this species around town look fantastic right now.
A nursery guy who seemed pretty knowledgable said people use Ironite to get color, but I can't imagine EVERYONE uses this for all the color that seems to come so easily every October here.
The soil is alkaline and not terribly rich, low in N. Is that basically what's going on? Could (my husband's) extensive lawn watering also be slowing them down? Your answers really appreciated.
