Planning to visit the horticultural information counter? If you need help identifying a plant or cultivation problem, follow the tips below.

Identification of a plant or a tree

Bring either the entire plant, some sections or representative pictures: stem with leaves, buds, flowers and/or fruits.

Observe and note:

  • The plant measurements (height, width, form) and its habitat.
  • The leaf arrangement on the stem (alternate, opposite, verticillate).
  • The form, size, color of leaves, flowers and/or fruits.

Identification of a problem (on annuals, perennials, shrubs or trees)

Bring representative samples of the damaged plant: leaves, stems and/or fruits slightly, moderately, and highly infected. In the case of a tree, bring an infected branch of 30 cm or more.

Observe and note:

  • The growing conditions: Light (sun, shade), soil type (clay, sand), drainage, habitat (forest, garden, plants growing nearby...)
  • The symptoms: Insects, injuries, holes, spots, necrosis, outgrowths...
  • Their location on the plant: On leaves, stems, trunk? Everywhere equally or only on an isolated section? Inferior, intermediate or superior branches?
  • The progression of the symptoms: From top to bottom? From the center to the exterior?
  • Date of appearance of the symptoms and the speed of their spread.
  • Plant history: watering, fertilization, pesticides/chemicals applied directly on the plant or its surroundings, any unusual event that could have an impact on the plant (digging, construction, heavy machinery ...)

The service does not include:

  • Lab analysis (soil, disease, etc.)
  • Expertise for legal purposes
  • Landscaping plans
  • Monetary appraisals of plants
  • Addresses or references for purchasing goods and services, including providers of horticultural goods and services
