Good lawn care starts with a few basic rules. If you follow these rules, problems are easier to sort out when they happen and are just simply less likely to happen anyway.
Mow at three inches or higher
This will allow your grass to supply the energy to grow deep roots, shade out competing weeds, and use less water than lower mowing.
Water deeply and infrequently
Surprisingly often I hear of people complaining that they are not getting enough water on their lawns, even when they are watering several times a day every day. This is happening because the turf is watered so frequently that it only grows shallow roots. Then it gets hot and the water evaporates quickly from the surface of the soil where the roots are. When you water deep and infrequently the roots have to go deeper where the water is not going to evaporate quickly and leave the roots to dry out.
Mulch mowing will cut down on thatch problems, cut down on the amount of fertilizer needed, and reduce the amount of watering needed, and improve the quality of top soil.
Keep the blade sharp
A dull blade shreds the grass opening it up to infection and water loss. A good sharp blade will also make the mowing easier. Take the blade off once a month and use a good file. If you have a big lawn that takes more than and hour or two you may be better off sharpening more frequently.
Change your sprinklers to mini rotators
The spray heads that have become so common over the past couple of decades throw so much water out so quickly that it often runs off the soil rather than soaking in. This is a waste of your water and creates wear on your expensive irrigation parts. If you switch out the nozzles for a mini rotator you will get slower watering, better water penetration into the soil, less water blowing away in the wind, and more even coverage.
Only mow the top 30% of your grass
Mowing is a shock for your turf. If you resist the urge to take off a huge amount of grass at every mowing the grass will be less stressed and will not need a huge recovery time. It will also be less likely to succumb to insect or disease attacks.
Aerate once a year
This may not be needed if you do not run, walk, or play on your grass. But if you use your turf it will help insure that your soil will continue to have open spaces for air, water, and growing roots.
Fertilize with a slow release fertilizer
Turf does not need a fast feeding. It needs to be slow and even. Slow release also means that you waste less fertilizer by preventing it from washing away.
I have seen so many people struggle with bad lawns because of poor care. I hate see this happen when simple improvements lead to a much healthier and satisfying lawn. So please, go over the list and look for things you can improve your good lawn care!
