Lawn Care, We do it Right!

Someone once said, "If you don't like the weather in Atlanta, wait 15 minutes, it will change!" That statement is the primary reason why proper lawn care in the ATL, as we are called, is such a demanding task!

The USDA categorizes plant hardiness climate zones in the United States from 1 to 11. Look at any of the many variations of the map and you will find Atlanta somewhere in either Zone 6 or 7. The weather in Atlanta is so unpredictable that most maps cannot accurately determine where we belong. Many seasons we are vulnerable to drought. Other times we are vulnerable to flooding. Even some areas of Atlanta are subject to one while some are subject to the other! What does this have to do with lawn care? A lot!

Weeds

Temperature and moisture are the prime factors that determine plant growth. "Plants" in this case includes your great looking turf as well as those pesky weeds. Dandelion, clover, chickweeds and crab grass and all the other weeds out there compete with your lawn for water and nutrients. Some weeds grow well in warm, dry areas, others thrive in moist, colder seasons. The best way to keep the weeds down is to maintain a dense, healthy lawn.

The key to a successful lawn care program is regular, year-round service. Keeping an eye on your property allows us to properly time the feeding of your lawn to provide it with the nutrients it needs to remain lush and strong. At times your lawn needs a dose of nitrogen to provide energy to allow strong green growth. Other times of the year your lawn needs phosphorus to strengthen root systems and withstand stress. Still other times of the year potassium is needed to build immunity to diseases.

Your soil's acidity or alkalinity directly influences the vigor and quality of the home lawn. Soil acidity is critical to the way plants absorb nutrients. Some fertilizers affect the ph balance of the soil. Soil acidity also increases with an increasing rainfall. An annual limestone application creates optimum soil conditions, maximizing the efficiency of fertilizer absorption.

Regularly servicing your lawn enables us to apply preemergence herbicides at the right time to prevent seeds from germinating and use the right amount of selective postemergence herbicides at just the right time to control weeds without damaging grass plants. And, if any controllable weeds do make their way into your lawn, we will return to treat them at no extra charge.

Sometimes Mother Nature needs a hand in achieving a proper balance. With a little help she can provide a lush, green lawn that you and your family will enjoy and you can show off to neighbors, friends, and even coworkers season after season. Call Precision Lawn Care today to find out how we can help. When you look good, we look good!

Why Leap Year?

If you don't already know, 2012 brings us a special year as this year is a "Leap Year". Leap year is traditionally known as the year in which the month of February contains Twenty Nine days rather than the customary Twenty Eight days. So Happy Birthday to those "Twenty Niner's". And for some, who are fond of wanting to remain Twenty Nine or have a penchant for starving off age thirty, if your born on February Twenty Ninth, you truly get to say that your Twenty Nine for an additional four years!

Our calendar is based off what is known as a Gregorian calendar which has 365 days to a year in it and is considered to be a "Common Year". We need our calendar system to keep in alignment with the suns rotation around the earth. That takes exactly 365 days, 5 hours, 48 minutes, and 46.5 seconds for the earth to revolve around the sun. That means the solar year is slightly longer than our 365 days calendar. If we kept using a standard Gregorian Calendar system, we would lose approximately six hours off of every year. If we continue on with the math, this would have us losing some 24 days for every 100 years. The Egyptians were the first to notice this difference of say "Time and Space" by using a ramped up version of a sun dial. To avoid this loss of time, we created what is known as a "leap year" by adding one extra day to the calendar once every four years. The reason the month of February was chosen as the month to add this day is that back in ancient times, the Romans were the first to pick February as the month to add an extra day to and the tradition has carried since. The Egyptians may have been the forerunners in creating leap year; it was the Romans were the first to pick February 29th as the additional day added for leap years,

Leap years were created by Julius Creaser and they were added to what is known as the Julian Calendar. There was however some trouble with Caesar's math. Caesar's calendar had a conclusion that if a year could be evenly divisible by 4, then that year would be a leap year. The problem with this math was that it created too many leap years and wasn't corrected until 1500 years later. Pope Gregory X111 modified the Julian Calendar in 1582 which kept the spring equinox on March 21st in sync with the solar year. Thus was the introduction and creation of the Gregorian Calendar. The first leap year occurred in the United States in 1752 when the Gregorian Calendar was accepted. The year 2000, in addition to the hoopla that Y2K brought, was also the first year where the third principal was used in the majority of the world since the transition from the Julian Calendar to the Gregorian Calendar

The Gregorian Calendar corrected the math and instituted the policy that in order to be a leap year, the following principals had to apply.

  • The year is evenly divisible by 4;
  • If the year can be evenly divided by 100, it is NOT a leap year, unless;
  • The year is also evenly divisible by 400. Then it is a leap year.

So the next time your kids ask you why they need to do math, you can tell them if people didn't know how to do math, they wouldn't know what time it was or what day it was, this should have them thinking!!!
