A: Looks like lack of water, but there may be other problems. If they were my shrubs I would get an onsite inspection from a certified arborist that works in your area and is familiar with local issues such as diseases, insects, cultural problems ( heat, lack of moisture, etc). To find a professional in your area go to and enter your zip code. Good Luck Nancy
