Mowing Methods Make a Difference

Mowing is an important and often overlooked landscape best management practices that can increase lawn health.

Most of us mowed lawns to earn some spending money as kids. As long as it was shorter when we finished than when we started our customers were happy. Although mowing seems like a simple chore that anyone can do, it turns out that improper mowing can cause a lot of damage to lawns and can increase pest and disease issues.

Make sure your lawn mower in good working order. Ensure the blades are sharp and the engine is not leaking any oil or gas products that may damage your lawn. Dull or damaged blades will give a ragged cut to grass blades that make it easier for disease and insects to attack your lawn. Leaking fuel products can damage or kill turf. Keep your mower clean by blowing or rinsing it after use, this simple step will also reduce the spread of weeds, insects, and disease.

Know the recommended mowing height for your type of turf (see table below) and follow it! Cutting turf below the recommended height places stress on the grass and encourages shallow roots. Deep roots help turf handle stresses such as drought, shade, insects, disease, or traffic. If any of these circumstances are occurring, the mowing height should be increased and fertilization should be decreased.

Mowing Height Table

Turfgrass Type Recommended Mowing Height
Bahiagrass 3.0-4.0 inches
Bermudagrass 0.75-1.5 inches
Centipedegrass 1.5-2.5 inches
St. Augustinegrass 3.5-4.0 inches, Dwarf Cultivars 2.0-2.5 inches
Zoysiagrass 1.5-2.5 inches, cultivar dependent

 

When mowing, never remove more than 1/3 of the leaf blade per cutting. If the grass is overgrown, plan to mow in stages to avoid scalping or removing too much of the leaf blade. Just like shrubs, turf needs leaf surface area for photosynthesis. Allow clippings to fall onto lawns rather than catching them or discharging onto hard surfaces. The grass will decompose rapidly and provide nutrients to the lawn. Clippings that are blown onto sidewalks, streets, or other hard surfaces may be washed into storm drains and get into water systems. Just as decomposed clippings provide helpful nitrogen and phosphorus to our lawns, these same nutrients are harmful to our water bodies. Keeping them in lawns is a great way to recycle and to keep our water clean.

I noticed aphids on my lettuce and planned to take them in to show some students. On the planned date I found they they had been consumed by parasitic wasps. I felt it was a sign of a balanced ecosystem.

I was actually wondering about the issue with the mower blades. I am constantly getting the ends of the grass cut on a way that has the tip of it drying out. Is the fact that the blades are a little worn, that is causing this issue of the grass getting dry at the top.

For sure on the Aucuba! I love it and use it throughout my front yard along with the cast iron plants. One of my favorite shade plants however is the Apostle's Iris, 'Neomarica gracilis'. They have survived the coldest winters so far and have come back beautifully. Thanks for the article. I have 2 shady beds I am renovating right now so I look forward to finding the Japanese Plum Yew and the Mahonia!

Nice article Julie. Just a side note that occurred to me as I looked at the pictures. Please don't recommend (I know you didn't in this article) that people plant close to the flare roots of a tree. The first radial distance of 3x the DBH of the tree is very, very important root area and what the arborist needs access to for many treatments. As important, perhaps more important is: 1. the tree trunk and exposed flare roots need to be dry when it is not raining and having vegetation in close proximity eliminates the breeze and keeps the tree trunk damp creating a decay/fungi opportunity; 2. cast iron plant, Jasmine, fern, etc. are major competitors in that critical root area. If a tree is stressed one of the cultural remedies is to clear out plants in that critical root area and install organic mulch, preferably pine straw. Keep up the good work!!

Hi Stan, I don't know how frequently that is done, however, if the gardener plans to change out the plants after a very short period of time they may leave them in containers. Some commercial properties may do that if they plan to swap out if anything declines (theme parks, other high profile spots), but most plants should not stay in original containers indefinitely. Eventually the plant's root system will outgrow the pot and will be unable to take up enough water to sustain itself. Julie

Miss McConnell, Is it a common practice by some homeowners to leave the annuals in their pots when they plant them in the Spring? Thank you

Hi David, The palm you are describing is likely Butia capitata also known as Jelly Palm or Pindo Palm. The fronds have a bit of a blueish or silvery color to them that makes them fairly distinctive. More can be found about this palm at the following link http://edis.ifas.ufl.edu/pdffiles/ST/ST10500.pdf. If you like, send a picture to my email and I can confirm if that's what you have. Have a great day! Julie juliebmcconnell@ufl.edu

We have a palm, locally known as a Jelly Palm" It's a very slow growing, like 12 feet in 15 years, and very bushy compared to the typical King palm. It puts out small groups of flowers, inside a hard, 3-4 ft. long woodlike, split, shell, which, of course become seeds. That is apparently what some old timers used for "Jelly:". Jelly Palm is not likely it's correct name. From that vague description, can you tell me what it is, or if not, what I can provide to help properly name it.

Hi John, Butterflies are rather specific about where they lay eggs and which plants their larvae (caterpillars) will feed on. For the Gulf Fritillary, the passionflower vine is the preferred larval host. I would not expect having this plant in your garden would have any direct effect on the number of caterpillars that would target tomatoes and peppers. If you would like to learn more about pests that are more specific to tomatoes and peppers, please see the following publication at http://edis.ifas.ufl.edu/pdffiles/IN/IN16900.pdf "Insect Management for Tomatoes, Peppers, and Eggplant"

Hi Suzy, The link should take you to a leaflet publication by USDA Forest Service titled "Walnut Caterpillar." I checked the link embedded in the article and it is working tonight, but sometimes there can be other issues. I am adding the link below in plain text so that you can try to copy and paste into your internet browser. If you are still unable to access it I would be happy to scan it and send it to you directly as a .pdf in an email next week. Julie http://www.na.fs.fed.us/spfo/pubs/fidls/walnutcat/walnutfidl.htm

Noticed one of our longleaf pine saplings, in the middle stage has died out on the top 3" of the bud. The trunk and several lower limbs still have healhty green looking growth buds. We are located 3 blocks north of the Gulf of Mexico in Franklin County Fla. elevation +27' sandy soil. Approximately 25 trees are @200yr old, some cat faced. Another 50 trees are post turpentine era, and another 75 are in the grass and middle stages. We eliminated all the loblolly pine 10yrs ago in hopes of restoring the longleaf presence on our 4+acres. Regards, Paul Standish

What type of grass do you have? If you have centipede, you will not need any additional fertilizer for the season. How much did you put out in August/

Kenneth Smith

Applied fertilizer to grass early August as I was away for 5-6 months. Can I apply again on 9/15?
