SPRINGTIME
LAWN ENJOYMENT
When
spring arrives everyone is dying to get out of the house and enjoy
the yard and that nice green grass. However, in order to have
nice green grass to enjoy, there may be a few things that need
to be done. There are two different sets of instructions for this
depending on your lawn.
1.
If you have measured your lawn area, done soil tests, followed
their recommendations, and the lawn is looking good:
......and
the latest test showed that your pH and nutrient levels are good,
then all you need to do is follow the test recommendations for
a May 15 fertilization. Team this with sharp blades on a mower
set to cut at 2-3 inches and you are on your way.
*It
is recommended that you fertilize at half the rate about May 15
because a heavy fertilizer in the spring will cause excessive
spring growth that can do more damage than good to the grass and
cause you to mow quite frequently. Heavy fertilizing in the spring
will bring the roots close to the surface to get the nutrients
and then, when the weather gets hot and dry, the roots dry out
faster. The fertilizer recommendation is usually for a 4-1-2 ratio
(such as 16-4-8 or 24-6-12). The only time weed & feed fertilizer
is recommended is for the October application as it contains too
much fertilizer for the other applications.
2.
If you have not done soil tests and your lawn does not look great,
but you don't want to dig it up:
....the
first and most important steps are to measure your lawn area and
do a soil test. A soil test will determine which nutrients are
available in the soil and give recommendations for fertilizer
applications. It will also tell you if the pH range is correct
for the plants you are planning to grow. If the pH is not in the
correct range the plants will not be able to use the fertilizer
no matter how much you spread - a big waste of your time and money!
The soil test should be done early so the results will arrive
before you start your spring maintenance. The instructions, forms,
and boxes are available at your county Extension office. You should
submit one sample each for the front and back yards. If you have
a large yard with varied conditions and are willing to treat each
section individually you can submit a sample for each area. Different
plants have different requirements so, for best results, you should
also submit soil samples for vegetable and flower gardens. To
determine the type of soil you have, which you need to know for
completing the form, put one cup of the soil test mix in a quart
jar, fill it with water and shake. The sand will sink to the bottom
in 40 seconds, the silt will settle within one hour, and the clay
will settle slowly over a couple of days. Your soil type is whichever
there is the most of in the jar. Soil tests should be done every
two to three years.
Read
the *paragraph above and follow the fertilizer recommendations
that come with the soil sample.
If
lime is needed to raise the pH to the ideal 6.2, the test results
will tell you how much to apply. If more than 50lbs/1000sq.ft.
is recommended, apply it in several applications of 50lbs/1,000
sq.ft. each, at intervals of 1 to 6 months, until the full amount
is applied. Applying more than that at one time will burn the
grass. Also, lime should be spread 2-3 weeks before or after the
fertilizer-not at the same time. Pelletized lime is the easiest
to use when spreading it on an established lawn. Ground limestone
is cheaper but messier and recommended if you are starting from
scratch and tilling the soil. If the test shows that magnesium
levels are low use dolomite lime. Lime can be applied at any time
of the year that the soil is not frozen.
If
you have a lot of weeds in the lawn and want to get rid of them,
call the Extension office for current chemical recommendations
for the type of grass and weeds you have. Some weeds are treated
in the spring and some are treated in the fall. Do not spray weed
killer on newly seeded lawns until the grass has been mowed at
least twice or it could be damaged and be careful not to get sprays
on plants you want to keep. Mark and use one sprayer for "weed
killers only" because the chemical residues could kill plants
later when spraying for insects or diseases.
