Proper watering techniques are essential to getting a healthy, attractive lawn.
Occasional downpours are not enough to ensure your soil has been
sufficiently soaked. A regular water schedule is essential for maintaining a
healthy, thick, green grass. Preferably water in the early morning or late
evening. A rain sensor is recommended it can save up to 20% of water usage
a year and usually pays for itself the first year. Watering in the morning or
evening conserves water that would evaporate if you were to water later
during mid day, but also allows grass to dry before evening. Grass that
remains wet for long periods in the dark is more susceptible to disease
development and mushrooms and fungus. The important thing to remember
for what time of day you are watering is the final run time of your last zone.
For example, if you have 6 zones set at 15 minutes per zone it will take 90
minutes to complete the whole cycle.(6x15) If you set your time at 7 am in
the morning you are really watering till 8:30am not just 7am and the sun will
be out for sure by then.
Note- If your lawn has turned brown and lost color during a drought dormancy
period, it will take several weeks of steady watering to spur regrowth from
the crown area of the plants.
How to pick the right amount of time per zone?
The water time per zone will vary for each different hydrozone you have. A
hydrozone can be grouped by the plant type (a drip system for shrubs, and
plants or sprays, rotars, or rotarys for turf lawn), a zone for shady areas or
areas that receive extra sun, and also by which type of sprinkler nozzle used.
Generally, shrubs and plants need to be watered for less than half the time
required for the lawn tuf. If you water the same amount for your drip, as your
other zones you are probably over watering your plants which can lead to
improper root development and decay from flooding roots.
Note-Spray heads are the least water efficient heads generally but are used
frequently in tight areas, Rotars are more water efficient than spray heads
they throw water further too, rotarys are a hybrid sprinkler that has the same
head as a spray head but functions similar to a rotar they are the most water
efficient besides drip systems.
Spring Clean up
March-April Spring Fertilizer. (Also, in the Spring it's a great time to aerate)
Aeration helps the water get down to the roots of the soil...soil in Colorado is
very hard and even watering a ton might not help the grass if the water drains
away without getting to roots. Aeration makes holes in the ground to help
fight this so water flows down properly.
June-July Summer Fertilizer with iron. (Also, it's a great time to apply an
application of Revive) Revive has a soil loosening agent which helps with
water penetration for proper root development and Revive is all organic so it
won't burn the lawn, it can be applied at the same time as fertilizer. Revive
makes it that per pound of water will do more.
September-October Winter Fertilizer. Winter fertilizer has a high content of
sulphur which helps the grass in dormancy. It's a great idea to apply
winterizer fertilizer so that your lawn will be healthy in the spring.
Fall Clean up/also, some people also like to aerate in fall
Letting grass grow tall and then removing more than 1/3 of the leaf blade is
called "scalping" and can damage the lawn. Mowing grass extremely low can
also damage the lawn by cutting into the crowns of the plants.
Sharpen Blades frequently
A sharp blade will cut cleanly. Dull blades can shred grass and cause
discoloration at the tips because frayed grass blades lose moisture easily.
Be Gentle with Damaged Grass
Raise the mower height a notch or two when mowing a lawn that's recovering
from drought, insect damage or disease
mowing once every 7 days, (allowing lawn to grow too high causes thatch
Mow at proper height setting
What is the proper height? When mowing, you should remove no more than
one third of the grass blades. How long you should keep your lawn depends
what time of year it is, but generally your lawn should be between 2 ½ and 3
inches high. During the early spring and late fall when the weather is cooler,
your lawn should be no shorter than 2 ½ inches. Late spring through early fall
when the weather is hotter and drier, a height of 3 inches is best.
