March Lawn & Landscape Tips

March!  March, the month all of us lawn and landscape enthusiasts celebrate spring. 

March, the month being outdoors on your lawn, in your landscape and on your patio returns! 

March, the month full of rollercoaster temperatures!  Ouch, really?  Did we have to go there? 

But it’s true.  All the sunny 65 and over days make the occasional below freezing, winterish night hard to bear. 

Oh, I’m not talking about you and me, I’m talking about your lawn and landscape. 

Tulips are putting on an early show this spring.

One of the hardest things for your lawn and plants is to arrive at the point of buds popping, flowers bursting, and lawns breaking dormancy… and WHAM! another wintry night arrives!

Spring is arriving early this year, much earlier than the last two years.  A few years back we had a warm February, an early spring, followed by a very cool late March with a freeze.  When the freeze arrived many plants and even warm season lawns, with tender young growth, were knocked back.  That year it wasn’t until mid-May before lawns and many plants snapped out of it.

The best spring for your lawn and landscape, and yes for you too, is once we reach the point of buds swelling, green shoots appearing in the lawn, and early spring plants gracing our world with bright colors; the roller coaster temperature swings are more like a kiddy coaster and less like Six Flag’s Texas Giant. 

So, get outside.  Enjoy all the wonderful days.  Do something in your lawn and landscape. Just don’t jump the gun on planting tender annuals just yet.

 

Here are a few lawn and landscape tasks you should tackle this month:

Spring flowering bulbs, like these daffodils, are already cheering on the arrival of spring.

The bright yellow of Forsythia is a show stopper!

Spring Lawn Maintenance – Get the mower out and get started.  It is much easier to remove the winter damaged leaf blades before the turf begins to green-up.  Remember, scalping on the lowest setting isn’t required and isn’t recommended.  Simply mow the lawn at the height you plan to start the mowing season. 

For most Bermuda lawns, the second setting is recommended.  For fescue, start on the second or third notch on your mower. 

We are often asked about dethatching at this time of year. 

What is dethatching?  Dethatching is the removal of excessive thatch that builds up on the soil surface by using a vertical power rake.

But, unless you have a thick layer of ½-1” or more of thatch, dethatching causes more damage to the crown of the plants than it does good.  So, with only a few exceptions, the best method for reducing thatch is an initial spring lawn maintenance followed by aeration after spring green-up.  Unnecessary dethatching and scalping the lawn too low removes the canopy opening the lawn up to disease and weeds.

Need more info on the first mowing of the season? Check out last week’s post. 

If you haven't already, cut your fescue lawn to remove the freeze damaged leaf tips and soon the lawn will return to full color and start growing.

Lawn Maintenance – With so many warm days, soil temperatures reaching into the low 50’s, and the occasional rains, fescue lawns are regaining color every day.  Start your cool season lawn off right by maintaining it at 2 ½ - 3”.  When it starts growing mow frequently enough that you are never removing more than 1/3 of the leaf blade per cutting.  So, if you plan to maintain a 3” level, don’t allow the lawn to grow past 4.5” without giving it a trim. 

If you have warm season turf, Bermuda or zoysia, after you cut the lawn for the first time to remove the brown winter damaged leaf blades, most likely you can put off regularly scheduled lawn mowing until April.

Saucer Magnolia is a small deciduous tree with saucer-shaped white, pink or purple blooms in early spring. It makes a great specimen tree from the spectacular spring blooms to its spreading, multi-trucked shape.

Tulips have started blooming...2-3 weeks ahead of normal.

Lawn Weed Control – Summer annual weeds begin germinating when soil temperatures consistently reach 55 degrees.  All the above normal temperatures have soil temperatures hanging out around 50 degrees.  Unless we see an extended cold spell, we are on course to see soil temperatues consistently reach 55 degrees by mid-March.   

If you have not applied the first spring pre-emergent yet, please do so by mid-March.  Whether you apply a pre-emergent yourself, or we do it for you, always follow instructions.  Watering is a required step to move the herbicide into the top ½” of soil.

Want to know what crabgrass will do to your lawn this summer if you don’t apply a pre-emergent? 

This is the month landscapes are filled with the bright pinkish-red colors of Redbuds, the Oklahoma State tree

Bed Weed Control – March is an excellent month to apply a plant safe pre-emergent to your landscape plantings.  Use caution in selecting the product to make sure it is safe for your plants.  When possible, select a granular pre-emergent mixed with a fertilizer containing approximately 20% nitrogen. Doing so will give your plants a good spring feeding while preventing weeds at the same time.

 

Lawn Fertilization – This month is a good time to start fertilizing your cool season lawns.  Use a fertilizer with 25-30% nitrogen.  Cool season lawns need to be feed more in the spring and fall when they are actively growing, and less in the summer. 

If you have a warm season lawn, wait until lawns have greened up to apply the first fertilizer application. 

Hyacinth is one of the first spring blooming bulbs to add splashes of color to the landscape.

Mulch – Spring is a great time to mulch your landscape plantings.  Maintaining a 2” layer of organic mulch will reduce weed population, retain soil moisture, and provide a more consistent soil temperature for plant roots.  I find adding mulch an easier task in the spring when I am cleaning my landscape plantings for the first time. 

Irrigation – It is always important to monitor rainfall and water based on need.  Continue the best practice of watering anytime we go a week without a ½” of rain.  If possible, wait as long as possible to start watering every other day.  You will save both water and money if you water on an as needed basis for the next couple of months.

One sign of how early the spring is this year…Hydrangeas are already budding. As long as we don’t get another hard freeze, this should be spring full of color.

Flowering Quince with bright orange to red flowers is one of the first shrubs to declare spring.

Spring Seasonal Color – Pansies are the toughest winter annual color, but it is common for them to look a little freeze burned after the winter.  With the early spring, as long as the crown was not damaged, they are returning to life and blooming.  The great thing about pansies is they add color to the spring landscape until it is warm enough to plant summer annuals.    

Wait till April to plant impatient, begonia, geranium, etc.  And remember most summer annuals need the warmer soil temperatures of late April or May before they are planted.  If you get in a hurry, you will end up planting your summer annual color twice.  When planting remember most plants prefer well drained, organic soil and would prefer you add compost when planting.

Seeding Fescue – March is the second-best time to overseed fescue. But it comes in a very distant second to seeding in the fall.  Spring seeded fescue will come up very well and look very good till the summer heat arrives - then it fades quickly.  Fescue, being a cool season grass, will not establish a sustainable root system when planted in the spring.  Give your fescue lawn a chance to green up first to get a better feel on the overall condition of the lawn.  If still feel you have bare areas that need to be addressed now, seed this month but still plan on seeding again in the fall.  In most cases waiting till fall to seed is best. Fall seeding allows you to focus on weed prevention and turf development in the spring and turf establishment in the fall when it is best.

Creeping phlox is one of the first perennials to burst with color in the spring.

Pruning – March is the time to do heavy pruning on your roses.  March is also the best time to make a major reduction in the size of hollies, boxwoods and most broadleaf evergreens.  Before spring growth arrives, you can successfully remove all the foliage back to the central leader if needed.

August Lawn & Landscape Tips

We have arrived at the hottest, driest point of the season.  The last 10 days of July and the first 10 days of August are when Oklahoma City’s average daily temperature reaches its peak.

Our goal is to help you get your lawn and landscape through August.  The key to surviving the hottest period of the season is best practices.

Best practices, not just during times of high stress, but rather it is using best practices all the time that makes the difference.

Finish the summer strong.  Focus on these best practices in August:

 

This week I started mowing my fescue lawn one setting higher. More leaf space results in better heat and drought tolerance.

Mowing – Both warm season turf (Bermuda and Zoysia) and cool season turf (Fescue) should be mowed at the highest level this month, warm season 2-2.5” and cool season up to 3-3.5”.  At the higher level, the lawn will have more leaf space resulting in better heat and drought tolerance. Continue to mow often enough that you are removing only 1/3 of the grass each time you cut.  If you are cutting frequently enough to pass the 1/3 test, don’t catch the clippings.  Allowing the clippings to decompose on the lawn will return moisture and nitrogen to the soil. Give no bagging a try.  You will be surprised at how much more color your lawn will retain even in the heat.  When you bag your clippings, you are tossing out nitrogen and water your lawn could really use this month.

Best Mowing Practice for August – Mow high, mow often, and don’t bag your clippings.

Bermuda lawns perform their best in the heat. Mow often and don’t bag the clippings. Grass clippings are mostly nitrogen and moisture. Your lawn will thank you for giving them back.

After mulch mowing, use your blower to distribute any noticeable clippings.

Heavy rain in early July was a recipe for Brown Patch development. Most fescue lawns have an area of low air circulation or heavy shade. My fescue is struggling with brown patch close to my front door where dense landscaping reduces airflow allowing the grass to stay wet for long periods of time.

Healthy lawns have deep root systems.  Roots will grow to the moisture.  If your watering pattern is short, shallow, frequent watering resulting in moisture only in the top 1-2”, you will have a shallow-rooted lawn dependent upon daily water.  Deep soaking results in a root system with grass roots 6” to 2’ deep that is not dependent upon frequent watering and is drought resistant. 

Remember, trees planted in the last two years need supplemental watering during the summer heat and extended dry periods. A good rule of thumb is to give them 10 gallons of water every week.

Best Watering Practice for August Know how long you need to water to get 1 ½” water on your lawn each week.  Practice deep soaking and infrequent watering.

Watering – The abundant soil moisture from the wet July start has quickly disappeared over the past week. The best-looking lawns and landscapes are now receiving 1 ½” of water per week now.   

To learn how long and how often you need to water for your landscape to receive 1 ½” of moisture, place small cups or cans around your lawn.  Water using your normal cycle and then check the cups.  Adjust watering times and frequency accordingly to insure 1 ½” is applied each week.  Remember your landscape prefers deep soaking, infrequent watering over shallow, frequent watering.  Even in the heat, lawns, and landscapes are at their best when they are watered deeply as needed and not every day.

Take time to check your irrigation and fine tune it. A leaning head often is the culprit for dry spots in the lawn.

If you are unsure about your watering practices, let us help. 

We can schedule an Irrigation Audit/Check to make sure your system is operating at its peak efficiency during the summer heat.

Fertilizer – Apply fertilizer to warm-season turf this month.  This time of the year, Bermuda and Zoyia benefit from a high-nitrogen fertilizer that is low in phosphorus and potassium. 

DO NOT fertilize cool-season lawns until we reach the cooler temperatures of September.   

Warm and cool season turfs require different fertilizer schedules.  Don’t make the mistake of trying to treat them the same when it comes to fertilizing.   

Best Fertilizer Practice for August – Fertilize bermudagrass, don’t fertilize fescue.  Important - Follow watering instructions after fertilizer is applied.

August is the month to be less aggressive on weed control. Because a thick turf is the most important part of good weed control, you want to avoid weakening the turf going into the fall.

August is the month to be less aggressive on weed control. Because a thick turf is the most important part of good weed control, you want to avoid weakening the turf going into the fall.

Weed Control – Spring pre-emergent herbicides are reaching the end of their effectiveness in your soils.  Should an occasional weed show up in your turf this month, it is best to go easy on weed control.  We have reached the time of the year when damaged turf may not have a chance to fully recover before fall.  Great weed control is at least 75% the result of thick turf.  August is the month to focus on turf development going into the fall.

Later this month is the best time to start applying the first fall pre-emergent herbicide application.  The first fall weed to germinate is poa annua (annual bluegrass).  Poa annua has become more and more of a problem to control in lawns worldwide as it has developed resistance to current herbicide chemistry.  For the best prevention, it is important to put a pre-emergent on your lawn between mid-August and the end of September followed by a second pre-emergent, using a different herbicide, in October or November. 

 

Best Weed Control Practice for August – Don’t cause turf damage by overtreating for weeds.  Better to go into the fall with a thick turf than one with herbicide-damaged thin areas.

Bermuda vs Fescue in August – Bermuda (warm season turf) loves the summer heat.  Fescue (cool season turf) prefers nights below 70 and days below 90.  Healthy Bermuda lawns look their best in the heat of the summer.  Healthy fescue will retain color, although not as much as in early summer, and growth will slow. 

7.5” of rain between July 6th and the 13th was great for Bermuda lawns, but not so great for fescue. 

Fescue where there is plenty of air circulation and some sunlight took the wet and warm weather well.  Fescue lawns with heavy shade and little air circulation are suffering from brown patch.  Brown patch occurs in fescue lawns anytime the grass stays wet for 5 hours or more at a time and nighttime temperatures are in the 70s.  For 7 days, Oklahoma City had the perfect conditions for brown patch development in fescue.  Many fescue lawns have areas suffering from brown patch, my lawn included.  Fungicides can suppress the disease, but it is hard to fully suppress brown patch with weather conditions like we experienced this July.

Inspect Shady Lawn Areas - September and October are the best time of the year to establish fescue.  Now is the time to assess the areas of the lawn where Bermuda has become thin due to increasing shade (Bermuda needs at least 6 hours of direct sunlight to be thick), areas of the lawn where fescue did not perform well because of very dense shade (Fescue needs at least some dappled sun), and areas of fescue that have been damaged by brown patch this summer.   Because fescue does not spread you should plan on adding some seed every fall.

 

Best Fescue Lawn Practice for August – Inspect and evaluate your turf.  Check shade patterns and make a plan for overseeding low-light areas with fescue this fall.

Need Help Evaluating Your Shady Areas? 

We would be happy to evaluate your shade and make a recommendation. 

Just give us a call at (405)367-3873 or respond to this email.

Insect Watch – If grubs have been a problem in your lawn, August is the time to apply an insecticide.  Remember, the insecticide will kill desirable insects also.  Only treat for grubs if there is evidence of a problem.  

Continue to inspect shrubs for aphids and treat as needed.  A common host plant is the Crape Myrtle.

Inspect your trees and shrubs for active bagworms.  If you need help controlling bagworms, give us a call.  When possible, remove and throw away bagworms.  Don’t toss them on the ground because they will crawl back onto your plants. 

Watch for webworm in your trees this month.  The second generation of webworm is the one that causes damage.  If noticed early when the webbing is small, simply cutting the branch out is the best control.  If spraying is required, you must penetrate the webbing to gain control.

 

Best Insect Control Practice for August – Spend a few minutes inspecting your lawn and landscape for insect activity.  Treat as needed.

A common problem on Hackberry trees in the summer is nipple gall. Unfortunately little can be done to control gall-making insects.

Landscape Color – How has the color been in your landscape this season?  Sometime this month take pictures and make notes of the plants that are doing the best in your landscape.   

  • Black-eyed Susan’s are the perfect perennial to add color to the landscape during July and August. 

  • Crape Myrtles are loving the warm days and are rewarding us with abundant summer color this year.

  • Limelight Hydrangeas continue to brighten the landscape even on the hottest of days. 

  • Lantana, Penta, and Periwinkle are at their best now. 

What is adding great color to your landscape right now?  We want to know.  Send pictures please.

Lantana is one of the best heat-loving annuals and with so many varieties, there is a right one for every landscape.

This planting of Sunpatien, Begonia, Penta, Joseph Coat, and Melampodium started the summer looking great. But over the last few weeks the Melampodium has over powered the rest of the color. Note: “If using Melampodium plant it in the back.”

Having a great lawn and landscape through the heat of the summer is a result of good maintenance practices year after year. 

A great lawn and landscape is not the result of one season or even a full year of focus. 

A great environment is the result of discovering and developing great practices and then repeating them season after season, year after year.

If you need assistance in developing great practices or have questions concerning your lawn and landscape, give us a call.

What is your lawn doing for you?

Wow…it has been a long, hot, dry summer. 

A summer that has challenged every lawn enthusiast.

A summer that has forced many to ask, “Now why am I trying so hard to have a great lawn?”

 

Why do we work so hard to have a great lawn? 

Have you ever pondered what a healthy lawn does for you?

Is there anything more to a healthy, green lawn than just curb appeal?

 

Too often great lawns get a bad rap.  In the race to reduce carbon output and conserve water, many have forgotten the long list of benefits of a healthy lawn.  Concerns over water supplies, herbicides, pollutants, and your carbon footprint have caused some to race toward a more minimalist approach to landscapes and lawns. 

 

Has the American lawn, green, neatly trimmed, a symbol of civic virtue, outlived its purpose?

Is it good for the environment to replace living plants with artificial materials?

Yes, water will be saved.  Yes, there will be less fertilizer used. 

But is there more to consider?

 

Can replacing living plants with artificial materials really be a net positive for the environment?  

When it comes to the benefits of turfgrass, most people don’t give it much thought.  The environmental benefits of a healthy lawn are seldom considered.

 

Can you answer the question, “What is my lawn doing for me?”

 

Let’s explore a few reasons why a healthy lawn is important to our environment:

Turfgrass captures carbon.

Healthy lawns absorb carbon dioxide and replace it with oxygen.  A lawn is simply a grouping of thousands of oxygen-making plants.

The average, managed lawn, captures more carbon than a lawnmower produces.

The average lawn captures 300 lbs. of carbon per year and has a net positive impact on our environment. 


A 2,500 sq. ft lawn, half the size of the average lawn, provides enough oxygen for a family of four. 


What is a managed lawn?  A lawn that receives regular mowing, some fertilizer, and weed control applications.  Maintaining a healthy turfgrass environment provides us with a critical component of a healthy world – less carbon.  

 

  • An Ohio State Study found lawns that received only an occasional mowing and no fertilizer or weed control capture far less carbon.   

 

Maintenance habits have a significant influence on whether turfgrass helps or hurts the environment. Lawns cut too short typically create a negative carbon exchange.  Weedy lawns, nutrient deficient lawns, and drought stress lawns result in thin lawns that have a negative impact on the environment.    

 

  • EPA reports that turf grasses in the United States offset the carbon emissions of 5.2 million cars every year.

Actively growing and healthy lawns reduce heat.  

A well-maintained lawn around homes can reduce air temperatures on average by 15 to 30 degrees compared to concrete, asphalt, or gravel.

 

  • The California Energy Commission found the cooling effect of an average size lawn is equal to nearly 9 tons of air conditioning.

 

Grass cools the air by absorbing solar radiation and evapotranspiration.

 

  • Studies estimate that improved planting and maintenance of lawns and landscapes around homes could reduce total US air conditioning requirements by 25%. 

A healthy turf captures pollutants and reduces runoff.  

Less runoff increases the infiltration of water into the groundwater supply.  A dense root system traps and removes pollutants moving through the soil and into the water supply.  The natural filtration system of healthy turfgrass improves water quality. 

 

  • Lawns are the best natural water purifier.

 

Turfgrass is more effective at stopping erosion than any other plant.  Grass naturally slows runoff and allows more water to be absorbed.

Healthy lawns improve air quality.   

Healthy lawns contribute to improved air quality by acting as traps for dust and particles.  Because a lawn completely covers a soil surface, particles are prevented from being blown to another area.

 

  • Compared to hard surfaces, turf grass traps 10 to 30 times more air particles and pollution.

 

Lawns are a major component of higher home values.

Smart Money reported consumers value a home with a well-maintained lawn and landscape on the average 11.3% over the base value. 

Well maintained lawns are one of the most important factors individuals and families consider when deciding where to live.

Great lawns benefit the community and human health.

Green areas enhance community pride, provide places for people to come together, and promote outdoor activity. 

Lawns knit neighborhoods together.  Lawns connect people.

Studies show people who live and work with a view of lawns and landscapes compared to hard surfaces are found to recover from stress quicker, experience fewer headaches, and are more productive.

 

  • Two studies show that children with Attention-Deficit/Hyperactivity Disorder have shown that green spaces, such as lawn areas, experience less severe symptoms.

 

Studies have also found the noise absorption capacity of turfgrass is significant.

Lawns are where memories are made.  No doubt, everyone can easily think of fond memories in the lawn with family and friends.

The belief that well-maintained lawns are an environmental liability is short-sighted.  Don’t fall for the myth that a healthy lawn isn’t good for the environment.

Water concerns are legitimate. Education on proper watering is important.  Deep, infrequent watering, based on the lawn needs, is a key to developing a healthy lawn that is good for the environment. 

 

  • The scientific study “The Role of Turfgrasses in Environmental Protection and Their Benefits to Humans” stated, “the main cause for excessive landscape water use in most situations is the human factor.”

Excessive use of fertilizers and herbicides is a problem.  But, when used properly, according to the label, fertilizers and herbicides are important ingredients in creating a healthy lawn that is beneficial to the world in which we live, work, and play.

 

  • James Beard, Professor Emeritus of Texas A&M, said, “The environmental benefits of turfgrass are the most sensible and economically feasible approach to counter the greenhouse effect.”

 

So, what has your lawn done for you lately? 

Far more than you can imagine!

What can your lawn do for you?

Benefits of a healthy lawn.jpg

In the race to reduce carbon output and conserve water, many have forgotten the long list of benefits of a healthy lawn.  Concerns over water supplies, herbicides, pollutants, and your carbon footprint have caused some to race toward a more minimalist approach to landscapes and lawns. 

Over the past few years the media joined the war against the landscape with articles such as “The Life and Death of the American Lawn.  Grasses – green, neatly trimmed, symbols of civic virtue – shaped the national landscape. They have now outlived their purpose.” 

One of the hottest trends is the replacement of natural grass with landscape gravel or artificial turf.  Both have their place, but not at the expense of a healthy landscape of plants, trees, and turf.   

Is it good for the environment when living plants are replaced with artificial materials? Yes, water will be saved.  Yes, there will be less fertilizer used.  But, is there more to consider?

Can replacing a living plants with artificial materials really be a net positive for the environment?  

When it comes to the benefits of turf grass most people don’t give it much thought.  The environmental benefits of a healthy lawn are seldom considered. Most would have a hard time answering the question, “What is your lawn doing for you?”

Healthy lawns improve air quality by trapping dust and allergens.   

Dense turf reduces the blowing of soil particles.  Also, it only takes 25 sq. ft. of turfgrass to provide enough oxygen for one adult for one day.

Great lawns benefit the community and human health.

Green areas enhance community pride, provide places for people to come together and promotes outdoor activity.  Research shows the result is improved physical and mental health and reduced stress.

The belief that well maintained lawns are an environmental liability are short-sighted.  Water concerns are legitimate.  Overwatering lawns and excessive use of fertilizers and herbicides drive much of the concern.  Education on proper watering, maintenance, fertilizer, and herbicide use is important.
