When Verticutting and irrigation are just perfect.

After a fresh Verticutt, it's time to test the irrigation system.

Water at the right time.

Watering in the early morning or late evening when temperatures and wind speeds are the lowest will reduce water loss through evaporation. Check with your local Water Management District office or Cooperative Extension Service office to find out how often to water. Tighter watering restrictions may be in order for different counties ranging from one day per week to two days per week and as restrictive as from 8:00 am to 6:00 pm for no watering.

Lawns only need about ¾ inch of water in one watering session. Place empty tuna cans or measuring cups around the yard (all within the range of the sprinkler, some close, some farther away). Turn on the sprinkler for 30 minutes. After 30 minutes, measure the amount of water collected in each can/cup. Check to see if there was even distribution of water in all the cans/cups. If the cans/cups collected ¾ inch of water, then you know you need to water for 30 minutes. If the cans/cups collected more or less than ¾ inch of water, then calculate approximately how long you need to water your landscape so that it receives ¾ inch of water in each watering session.

So how good is your irrigation? Is it truly all about the design?  Some stuff to think about:

  • The size of the pipe delivering the water. 
  • The source ( pump, city water, reclaimed, etc ).
  • How many gallons of water will each source deliver?
  • How much water will each pipe size deliver? Most common pipe sizes (1/2" 12 gallons per minute GPM - 3/4" 18 GPM - 1" 24 GPM ) 
  • The size of the nozzle installed in the sprinkler. Most sprinklers have available many different size nozzles, they change the rate of precipitation and coverage area.
  • The type of sprinkler device used (rotors, spray heads, drip).
  • The distance between each sprinkler. ( always design for 100% coverage ) 

In the photo above the rotors are set about 25' apart. The spray from each head should reach the other with no wind 

( 100% coverage ).  Your goal should be at least (60% coverage) under windy conditions.

Verticutting benefits all grasses


The dominant grass in central and So. Florida is St. Augustine. The excessive top growth, along with the accumulation of thatch creates many problems.  Also creating mowing problems.

All grasses accumulate thatch, see thatch in different varieties below.


The accumulation of thatch reduces the ability of water, pesticides, and fertilizers to penetrate the root system. A strong healthy lawn needs deep root systems.  All types of grasses accumulate thatch. Thatch is not caused by grasses clippings.

 Other contributions to health problems?

  • Over-watering.
  • Overuse of reclaimed water, will also add additional nutrients.
  • Over fertilizing
  • Mowing to high
  • They all contribute to thatch, layering and unhealthy conditions.
 Why aeration or coring is a waste of money:

  •  Aeration will not solve one problem with St. Augustine grasses, discussed on this site. Reason, when you plug a hole in sand in will just fill back up with sand, making the process a total waste of money. The problem of layering will never be solved. Nor will it remove the thatch. 
  • As you move north of central Florida soils change, you find clay, lime rock and other mixtures that may need aeration, but not lawns grown on sand!  Even if you have sod that was grown on muck, as some sod farms do in south Florida, that is only 2" , the rest in most cases is sand.

Grasses such as bermuda  are most common for use on golf greens and fairways and now Zoysia is being sodded on Florida lawns. They are constructed differently and do require aeration and verticutting more that once a year.

Cutting Up

By Larry Jones, Jacobsen, A Textron Company

There is a missing link in many lawn care programs — an underutilized cultural practice that boosts turf health and, potentially, your bottom line. Vertical mowing is a healthy habit and a beneficial component of an annual turf care routine. Simply put, vertical mowing encourages turf to take its vitamins.

The practice turns up thatch and opens the turf canopy so it can drink up nutrients and water, and clear out room for fresh growth. Verticutting is an energy boost, setting the stage for green-up in spring and preparing turf for overseeding in fall ( northern lawns ). And most turf varieties appreciate verticutting — the vigorous mowing isn't limited to sports turf or commercial properties.

Verticutters, on the other hand, dig deeper into the turf canopy and penetrate the crown area of the plant, possibly below, severing stolons and stems. While groomers are designed to condition or stimulate new growth, verticutters are more rigorous and remove thatch. When a verticutter passes over a section of turf, results are visible.

Never waste your money on aeration of St. Augustine grasses.
