Before you contact the Infoline, you may be able to anticipate some of the questions we’ll ask you. Like detectives, clues and details help us to identify your problem accurately and offer personalized recommendations consistent with your objectives.
Clues to Report
Plant Health Diagnosis
- When did you first notice the problem?
- Is the problem present on just one plant species or variety?
- What is the color, shape, texture and size of the symptoms?
- Is the problem uniform or distributed randomly?
- What are your goals? Is it to grow food, improve aesthetics, create wildlife habitat, provide pollinator habitat, increase privacy, improve water conservation or create recreational space?
- Is the soil mostly clay, sand or loam?
- Is the plant exposed to six or more hours of direct sunlight, or less?
- Can the site be regularly weeded, mowed, pruned and watered?
- Do you plan to incorporate new plants into an established landscape, or do you want to start over?
These are just two examples of common topics for the Infoline. The more information you can share with us, the better we can serve you.
No matter what your question is, it’s helpful if you share where you live so we can provide suitable recommendations for your area.
Including photos with your question is often helpful. Here are some tips for how to best submit pictures to the UNH Extension Infoline:
- Photos should be emailed or sent through social media with a description of what is in the picture(s) and your question.
- Photos should be in focus.
- Include an object or ruler to demonstrate the size of the subject in the photo.
- Send several pictures, especially of trees and large shrubs. Include a close-up of the issue and a shot of the entire plant.
- For plant identification, send a photo of the entire plant and closeups of the flowers, seed heads or other distinguishing features. A description of where the plant is growing or what it looks like at other times of the year will be helpful.
- Provide pictures that show healthy parts and problematic parts of the plant. Let us know what percentage of the plant is in the same condition.
- The tops of mature trees are difficult to see and photograph, so we may need to refer you to an arborist who can do an inspection at your home.
