10 Most Common Lawn Problems in the Central Valley

Okay, so here is my top 10 list of common lawn problems. Some of them are damaging pests and some of them are the result of poor cultural practices. I won’t get into solutions today, but obviously you need to properly identify the enemy and know what to look for to take the right actions. Known problem now results in no problem later.

Crabgrass has to top my list.  It is an annual grass that germinates from mid February to Mid September.  Prevention right now is absolutely key.

Spurge is an annual broadleaf weed that pops up in both lawns and flowerbeds in roughly the same time frame as crabgrass.  It too is a heavy seed producer and needs timely applications of pre emergent to prevent its germination.

Sedges are perennial weeds that invade lawns and flowerbeds in the warm summer months.  Proper identification and selection of the right control agent will determine the level of suppression.

Broadleaf weeds like oxalis, dandelions, clovers, and thistles are extremely common to lawns throughout the valley.  Not all broadleaf weed control products are equal and proper identification will help one select the best product.

Diseases can damage lawns throughout the year.  Things like brown patch, snow mold, rust, spring dead spot, and southern blight.  Symptoms are usually circular in shape and the turf becomes discolored and often yellow.

Annual bluegrass or Poa annua is an abundant seed producer that invades dormant Bermuda lawns and flower beds.  This too is preventable with the proper treatments.

Bermuda is fine in a Bermuda lawn, but not so great in a tall fescue lawn as it goes dormant in the winter and leaves patches of brown in an otherwise green lawn.  Suppression is available only at this time.

Dry spots are usually the result of poor sprinkler coverage.  No water means no green grass.  This could be due to the spacing, water pressure, bad nozzles, or lack of proper adjustments.  Let’s fix sprinkler problems as water in a limited resource.  Overwatering is also a very bad and commonly observed practice.

Shade provides a great place to hang out in the summertime, but too much shade results in very thin lawns.  Shade management becomes more important as the landscape matures over time.

Mowing too short or too infrequently will put a stress on your lawn.  Weekly mowing at the proper height will make for a happier lawn. 


Well that’s my list and it is certainly not complete.  For your lawn questions and free lawn evaluation call Weed Man at 559-266-1624 or visit our website at Fresno.WeedManUSA.com.

  3. Thanks for the tips on lawn care. I never would have realized that the secret to getting rid of crabgrass is prevention. That makes sense that it comes in later in the summer. Hopefully I can have an awesome lawn this summer.

  7. Thanks for explaining what I can do about these common lawn problems. I noticed a lot more crabgrass popping up on my lawn last summer. Since it germinates from mid February to mid September, it seems like I should take action and try to get rid of it right away.
