What we need for plant identification:

  • If possible, submit the entire plant (especially for weeds); the roots may be important for identification.
  • For trees and shrubs — a branch with leaves attached.
  • Flowers and fruits are also helpful in identification.
  • Submit sample in plastic bag; do NOT water.
  • Wrap turf in foil; do NOT water.

What we need for insect identification:

  • Insect specimen, preferably alive.
  • Bring in a small jar or plastic container, so it doesn’t get squashed.
  • Detail the location where it was found.

What we need for disease identification:

  • For herbaceous plants, submit entire plant that has symptoms, if possible; otherwise, several leaves and stems.
  • For woody plants, submit the branch that has symptoms (living and dead parts).
  • Submit sample in plastic bag; do NOT add water.
