To help us better diagnose a plant problem, please try to share as much of the following information as possible:

  • What type of damage are you seeing and when did it start?
  • Which parts of the plant are affected, for example, flower, leaf, stem, fruit, etc.?
  • How is the plant watered and how much, for example, hand watered 3 times a week for 10 minutes?
  • Where is the plant located, for example, in a garden bed or in the lawn, next to a driveway or house, in full or part sun, facing what direction?
  • Sharing photographs of your plant problem, plant identification or insect identification is helpful. See tips for sharing photos below.

CLOSED – We hope you will be able to visit a Master Gardener plant clinic again soon for FREE advice on gardening, plant problems, plant identification, pest management and soil improvement. See for the map to all clinics and gardens, when re-opened.


*Tips on Sharing Photos

Photographs of your plant problem, plant identification or insect identification are helpful. 

Here are some hints about the types of photos that will show evidence of a problem and will help us to make the correct diagnosis or identification:

  • Show the damaged or problem plant in the landscape along with other plants to provide additional clues to the probable cause of the problem.
  • Show the base of the plant at the soil line to determine root issues.
  • Show live branches/limbs and leaves, dead or dying branches/limbs and leaves to help us determine the spread.
  • Show buds and flowers to help with plant identification.
  • Show the insect if that is the suspected culprit in the damage, along with the kinds of damage you are seeing.
