Diagnosing Plant Problems
The Horticulture staff and EMGs are available to assist you in identifying your lawn and garden problems.
Tips for gathering samples to bring into the Extension office for diagnosis.
- Cut a piece of sod, including the upper root and soil layer, about the size of a salad plate, or about 6” x 6".
- Try to collect your sod sample from an area that contains some healthy and dying stages.
- A dead sample will reveal little information.
- Do not just bring in a handful of grass blades.
- Place the sample in a plastic bag or small container for transporting.
Tree and Shrub Samples
- A 1 – 2 foot branch or twig showing the damage is the most helpful for diagnosing problems.
- Avoid a limb that is completely dead, or bringing in a handful of leaves.
- It may be helpful to collect several limbs showing the various stages of decline.
- If possible, cut just before bringing into the office.
- If they must be cut and held, keep them refrigerated to preserve freshness.
- Avoid squashing the insect, if at all possible.
- Do not collect between pieces of tape.
- Instead, trap the insect in a small bottle or bag.
- If you need to kill the insect place it in a bottle containing rubbing alcohol.
- If possible, bring the entire plant to the office, pot and all.
- This gives us the best picture of what is going on with the plant.
- If this is not possible, a couple of small shoots are helpful.
- A leaf-only sample often does not show enough for a proper diagnosis.
- Attaching photos in an e-mail is easy and convenient to do.
- When taking photos for e-mailing, make sure to use the lowest resolution setting on the camera, as they e-mail much faster.
- Send several photos, including
- ones up close showing the damage,
- and one that shows the entire plant.
