When and for how long should I irrigate my St. Augustine Grass

irrigation st augustine grassAmong all of the grasses in Florida, St. Augustine seems to be the most finicky and problematic grass of all the species. Usually, the problem is with the irrigation and the aspects that come along with it.

The University of Florida states that there are three main characteristics of an irrigation plan for St. Augustine: Frequency, Duration and Time. If these three items are being properly attained, then the resulting turfgrass will be thick, strong, green, and vigorous, and will combat insects, weeds, and wild grasses more easily.

University of Florida states:

“A properly irrigated grass plant is better able to withstand pressure from weeds and insects. Weed problems in a lawn indicate that the turf has been weakened by improper management practice. Proper management practices can eliminate most weed problems.”

Proper irrigation in addition to a standardized Turf Treatment Schedule will provide optimal results for healthy grass.

Q: How Often Should I Run My Irrigation System? [Frequency]

A: For an already healthy lawn, two – three times per week*.

During the summer months, healthy St. Augustine can only go 1 to 5 days between irrigation events, based on the heat index (Myers & Horn, 1969). Weakened turf needs even more water.

*Always follow Local and State laws in regards to watering restrictions. As of July 2010, Florida residents can use automatic sprinklers 2x / week. Hand-watering hot spots or weak lawns may be necessary. Hand-watering is NOT prohibited, so long as it is after 6pm or before 8am.

Q: How Long Should I Water For? [Duration]

A: Spray Zones at 30 minutes, Rotor Zones at 45 minutes

The exact answer to this question is “½ to ¾ inch of water per irrigation event” (UF IFAS, 1999), but depth is harder to define than duration.

In an irrigation system with optimal pressure and proper coverage, the times listed above should provide the correct depth of watering. If you are following the above Frequency and Duration and still have “hot spots,” you may need to have your Sprinkler System checked by a professional.

Q: When Should I Water My Lawn? [Time]

A: The best time is in the early morning hours (1:00am to 3:00am), prior to the dew.
Watering in the late morning may be detrimental if it extends the time the lawn is naturally wet from dew, which may accelerate disease issues. Watering during the day wastes water due to excessive evaporation from the sun. Watering in the evening can lose just as much water to evaporation from the heat the earth gives off as it cools.

What Your Neighbors Are Saying About Mansfield Landscaping

We just moved into our Village’s home last fall and had many expenses with new furnishings, but we really wanted to have at least a couple of palms now and did not want to wait another year until we could afford to redo our landscaping. After checking with a couple of other nurseries we were very surprised at how much lower the prices were at Mansfield Landscaping. The owner, Steve was very knowledgeable about where trees should or should not be planted. We were given as much time as needed to pick out and tag the exact trees we wanted on our own, but if we had any questions he was just around the corner to answer them. The trees are beautiful and of good quality. We look forward to working with them in the future to give our yard that professional look that we see so many of our neighbors have after using Mansfield Landscaping.

Used Manfield and I am satisfied. Called him on Monday and he came the same day and gave an estimate and the work was completed on Thursday. I like that.

INCREDIBLE WORK BY MANSFIELD LANDSCAPING!! After obtaining numerous landscaping estimates to help transform our extremely large, unattractive corner lot in the Village of Largo we hired Mansfield. We sure made the right choice!! The owners, Steve and Ron, were extremely professional and prompt and spent a lot of time talking with us on the phone and in person to make sure we got what we wanted. As promised, they started the work 10 days later and COMPLETELY transformed the look of our entire home!! Our property went from the "eyesore of the neighborhood" (a quote from one of our neighbors) to stunning!! I am not exaggerating one bit. During the time Ron and his excellent crew were planting the 11 very large palm trees and countless plants and flowers and the past week when we've been watering all the landscaping at least 100 people have stopped by in their cars and golf carts to comment on what an amazing job Mansfield did!!! We couldn't be happier and can 100% recommend them to everyone.

Just completed our landscaping design by Mansfield Landscaping and they have exceeded our expectations by far!!! Steve and Ron and the whole crew are very professional and accommodating. They showed us patience in selecting a design, palm trees & plants. Their expertise and talent was proven to us by giving us the 'Wow' factor we were hoping for. We could not be more pleased. Our home is complete now, we can sit back and enjoy the beautiful view! Thank you Mansfield Landscaping.

The team from Mansfield just finished our front yard to include a walkway around our new golf cart garage. I must say that Sharon and I are very pleased with the end results. It was a bit difficult to visualize what the end would look like and my initial trepidation about the cost have been set aside. After seeing the amount of labor and materials required I can now fully understand the cost, in fact I think it was well worth every dollar we spent. John has a great eye and knows his way around the total job. We have some friends moving down from Baltimore and we will be recommending Mansfield to them. We are also a part of an open house tour within Mission Hills in mid November and believe me you will be receiving very favorable comments from us.

We had a great experience with Mansfield Landscaping. We visited the nursery and saw how healthy the plants were and then sat down with Steve and developed our own concept of palm and shrub borders on the side and front of our house The workmen did an excellent job and you cold tell they cared about how the plants were going in. We now get a lot of very positive comments from neighbors and strangers alike People are calling it "The Botanical Garden"! Mansfield Landscaping is a professional landscaper. They did a great job.

Thank you Steve and your crew.

John & Sandy

We would like to thank you and the crew of Mansfield Landscaping for the fine work done at our home. As with the previous work you have done for us, we were extremely pleased. It is unfortunate that it is so difficult to find people these days who take pride and ownership in their work and can be relied upon to do a job well. The Mansfield Landscaping crew was professional, dependable and timely. The hard work you and your crew gave to the project is commendable. The trees, plants and design you suggested have added beauty to our home.
