We encourage you to call, email, or visit us with your gardening problems, but there are things you can do ahead of time to improve your chances of a solution.
Whatever your initial viewpoint of the problem is, take a wider look at it. Be ready to describe the surroundings. Notice sun/shade patterns, notice other plants in the vicinity, and their state of health. Recall recent weather events as well as gardening activities such as fertilizing. Also take a closer look. If you have a hand lens, inspect it as closely as is reasonable. One of the first steps in dealing with a problem is to identify the characters, and often plant and animal identification hinges on small details.
A very useful thing you can do is to provide one or more pictures. Be sure to have a general (wider) picture to establish context, as well as any close-ups you can capture. These can be emailed along with the description of your problem.
There is one thing better than pictures, and that is the actual plant or bug that is the focus of your problem. This does require you to first collect the plant or bug in an appropriate manner, and then transport it to the clinic. The clinic office has a downloadable file which contains recommendations for collecting and transporting your specimen. You can download that file here, and be ready with the answers the Master Gardeners will need.
