Hello, I planted two Boston ivy plants in two planters in the spring, they have done very well but I have noticed that some of the leaves in one of the plants show a reddish colouration around the leaf — is this the Fall colour showing up, or something else that I should worry about? I do not see it in the other planter. Thanks
Thank you for contacting the Toronto Master Gardeners.
In fall, Boston ivy leaves begin a color transformation that goes from red to purple. As summer fades into fall, the days start getting shorter and there is less sunlight. This is a signal for the leaf to prepare for winter and to stop making chlorophyll. Once this happens, the green color starts to fade and the reds, oranges, and yellows become visible.
