Earn CEUs with the New Collection of Articles


ISA offers a variety of educational materials and products to help arborists expand their professional knowledge and experience. Every month, we will feature a product or group of products. In September, ISA is featuring the Collection of CEU Articles on Plant Health Care Volume 2.

Written by specialists in the field, the Plant Health Care Volume 2 is a compilation of CEU articles previously published in Arborist News. The selected articles aim to improve arborists’ understanding of the interaction between trees, turf, and plants in a healthy landscape. They discuss plant health care and related topics, such as:

  • biochar applications
  • pruning
  • tree injection
  • soil assessments and management
  • integrated vegetation management
  • tree lightning protection systems
  • the biology of woundwood and callus

Offered in a digital format, purchasers can access the articles and CEU quizzes on their desktop, laptop, tablet, or smartphone. Plant Health Care Volume 2 includes the opportunity to earn the following CEUs: 10 (A), 6 (U, Bp), 5 (T, L), 7 (M), 3.5 (Bs), 0.5 (Bm).

*You may earn CEUs for the quizzes in this set of articles even if you previously completed the Arborist News quiz from the same article. However, the CEUs for this set of articles may be earned only once during the lifetime of your certification. Make sure you're logged in to the ISA website to check if you've previously purchased these quizzes.
