Q.Red Buckeye Blooms Twice A Year
My buckeye blooms in the spring. It puts out its leaves and flowers but they drop around August. However it’s grows another set of foliage and flowers around September. It produces very few buckeyes. It used to behave normally 2 or 3 years ago and buckeye production was very good. What is causing this?

It is unfortunate but rather common for a red buckeye (Aesculus pavia) to decline in the hot summer months. A disease called leaf blotch could also be to blame. In order to prevent this issue, be sure to rake and destroy any and all fallen leaves to remove the overwintering fungus. You may also want to thin out the plant if it is too full and bushy to allow for better airflow. You could also apply copper fungicide to the plant once the buds begin to just break open.
