Submitting Plant Samples

General Tips

• Provide plenty of plant material. When possible send the entire plant, including roots and top growth.
• Provide lots of information, such as a description of the soil, nearby plants, and a history of the problem.
• Include photos when possible. We welcome videos and will return them to you.
• Provide freshly collected specimens.
• Be sure the specimen represents the problem.
• Include enough plant material to show all stages of the disease from healthy to very sick.
• Wrap specimens in paper towels or clean newspapers. Do not add moisture. Pack loosely in a plastic bag to reduce drying. Mail in a sturdy container.
