HOW TO BRING A SAMPLE

Please collect your sample on the day you bring it in, so it is fresh:

  • Fleshy plant parts (bulbs, fruits, and roots): Wrap specimens in  paper towels to absorb leaks.
  • Flowers and vegetables: Bring the entire plant, with the roots and surrounding soil if possible. Enclose the roots in a plastic bag and keep the soil from touching the leaves. Bring enough plants to show all stages of the symptoms; several whole plants if possible. Note the pattern of symptoms over the whole garden.
  • Foliar disease: Bring enough of the plant(s) to show all stages of the disease from healthy to very sick. Note the overall pattern on the plant. For example, are all the leaves affected or just the lower branches?
  • Grass samples: Grass samples are discouraged, as little can be diagnosed from a small sample. Minimum sample size is a 6"x6" section of grass with the roots. Include sick grass, grass on the edge of the sick area, and healthy grass.
  • Woody trees and shrubs: Collect branch samples that are showing the range of symptoms but are not dead.
  • Insect samples: If possible, bring several specimens. Include plant sample showing insect damage. Preserve soft-bodied specimens in rubbing alcohol.
