During the summer months, a lot of the landscape tends to look sub-par. The extreme heat can cause yellowing or browning of foliage, consistent rain can cause fungal infections, and bugs can cause numerous side affects. A horticulture oil or pesticide can assist with any pest issues, but make sure to spray the plants in the cooler hours like early morning or in the evening. See the pictures below to be able to identify your plant issues!
