Be On the LookOut

Month-by-month lists of common plant diseases, pests, and other problems you may encounter in North Carolina yards and gardens. Authors: Matt Bertone, Mike Munster, and Lee Butler, Department of Entomology and Plant Pathology.

CAUTIONS TO THE USER

  1. There are many diseases, disorders, and arthropods not included in this list
  2. Many arthropods can be observed throughout the mild or warmer parts of the year (March-November), and are not included here.
  3. Problems can occur in months other than those indicated, though less frequently.
  4. Timing and occurrence of these pests and diseases may vary across the physiographic regions of the state.
  5. Always check the “multiple hosts” listings at the top of each section, as well as the individual plant of interest, since not every problem is listed for every individual host.
  6. These lists are based on data and experience in the state of North Carolina, USA and may not reflect phenology elsewhere.
  7. Revisit these pages periodically, as new items may be added over time.
  8. Since their problems don’t change much over the course of the year, there’s a separate BOLO page for houseplants.
