Shade Stress!

Apr 18th, 2017

While perennial ryegrass and tall fescue varieties might establish quickly in heavy shade, they will begin to thin significantly after the first year.

Shade stresses turfgrass by reducing green plant cells and carbohydrate reserve in the leaves.

The grass then becomes unable to make enough food to sustain new root and shoot growth.

When stressed- turfgrass also becomes more susceptible to shade-related issues.

Some typical turfgrass problems when planted in heavily shaded areas include:

  • Thinning and/or decline of overall stand.
  • Increased disease/pathogens.
  • Moss taking over.
  • Weeds moving into thin areas.


*It is ideal to provide 5 to 6 hours of direct sunlight to maintain a healthy turfgrass stand.

Some ideas that help in partial shade areas might include:

  • Selective pruning to thin trees- increasing filtered light.
  • Over-seeding with JB Instant Lawn Seed Fall/Spring that match your particular lawn
  • Additional JB Signature Premium Fertilizer as needed.
  • Aerate to increase oxygen availability.


Shade and Turfgrass don't mix--- Keep it green, dense and happy---- and remember your lawn needs sun!!
