Plant Fungal Diseases


The time to treat plant fungal diseases is approaching!  Most treatments will begin in the early spring just as the leaf buds are opening.  Timing is important for good results.

Here are some helpful questions in determining if your landscape plants have fungal problems.

  • Do the leaves or stems have black or brown spots or patches?
  • Do the evergreen needles have tiny black spots on them?
  • Is there a white powdery or sooty appearance on leaves and/or buds?
  • Are the tips of the twigs wilting and/or dying?
  • Are there gelatinous gobs oozing from the stems and leaves/needles?
  • Is the interior of the plant dying?

If you witness any of these symptoms or suspect fungal problems, let us know and we would be happy to assist you.  Many of these issues can stem from over watering (such as a sprinkler hitting trees and shrubs every day), overgrown and thick plant interiors (such as a shrub that has not been pruned lately), or if a plant is under stress or is in poor health to begin with.

There are some fungal problems that will persist and deteriorate a tree year after-year such as needlecast.  There are also fungal diseases that persist, such as apple scab, that will not kill the tree.  We can assist in determining if a fungal problem exists and if remedies need to occur in order to sustain the life of your landscape plants.
