There is no magic potion to a healthy lawn - just ask the full time grounds people and green keepers! You cannot just throw any fertiliser on your grass and expect a perfect lawn to appear..... and even when you have a good lawn there is continual work to do to help it stay that way.
Tips to remember:
1. YOUR LAWN IS ALIVE
2. IT IS ALWAYS UNDER ATTACK FROM WHAT IS REFERRED TO AS A-BIOTIC STRESS
THIS MEANS THE GRASS IS TOO DRY - TOO WET - TOO HOT - TOO COLD 3. YOUR LAWN IS ALWAY UNDER ATTACK FROM THOSE DREADED PESTS OR DISEASE THAT CAN APPEAR QUICKLY AND WIPE OUT YOUR PROUD UK LAWN
Three vital requirements for the grass roots:
Above: this is a classic case of drought stress - obviously the lawn has been starved of sufficient water and is probably compacted so that when it is watered or it rains lightly the water will probably not permeate to the roots.
It is very important to get water permeated to send the roots deep . If you just lightly water the surface in times of drought the roots will turn towards the surface searching for the water. So if you are watering - water it thoroughly do not use feed unless there is sufficient water to carry the food to the roots.
There may well be something called DRY PATCH in certain areas so you need to purchase a wetting agent from any garden centre or large DIY store this will help the water to permeate through the surface.
HOW CAN I MINIMISE THE CHANCE OF THIS HAPPENING Regularly spike the lawn from early in the season. You can hire a spiker from the Tool hire shop if you have a large lawn or you can spike using a garden fork just spike to at least 4 inches deep. Keep the Lawn well watered when hot weather is forecast. The lawn should be spiked at least twice in a season - at the beginning and at the end of the season.
This lawn will recover within 2 weeks of heavy rain or heavy watering.
