Tips for Using Ask Extension

For fastest service:

  • Find answers to many common questions on our website.
  • Read our tips for submitting good photos. In general:
    • Insect photos need to be close up, in focus, in good lighting, and include a ruler or coin to indicate size.
    • Plants to be identified should show the entire plant, preferably with close-ups of flowers or seed heads.
    • If seeking a plant disease diagnosis, photos should show the transition from healthy to affected plant material. Please also include information on the age and location of the plant(s) and soil and site conditions.
    • You can attach files in JPG, PNG, GIF, or PDF format, a maximum of 8MB.
