Leaves are turning yellow with brown spots.
We highly recommend that you contact your Master Gardener first to determine what is causing the leaves to turn yellow and have brown spots. Once you know exactly what the cause is, we can help you select a product that will fit your needs. Please find their contact information by clicking on the link below.
