- During high temperatures and wet
conditions brown patches appear in the lawn. very similar to a light chemical
(fertilizer) burn or much like a urine burn.
Cause of Problem:
Brown patch is caused by a fungus
known as Rhizotonia solani. This fungus is attracted to the lawn because of the rapid lush
new growth of a high nitrogen feed lawn. The chemical fertilizer kills off all
beneficial bacteria and attracts these harmful bacteria and fungus. The root cause of all
fungal diseases is dead soil and stress.
Over fertilized soil, improperly
cared for, will die and along with it goes the support system needed by plants to grow
healthy and disease free.
The city water you use has chlorine (usually) added to it to
control bacteria in the water. It is this very anti-bacterial water that kills all
beneficials in the soil further adding to the damage caused by chemical usage.
The Organic Solution:
Take better care of your soil!
Top dress with compost several
times per year. Top dress with rock dust several times per year. Aerate each time before
topdressing is done. Composted horse manure makes a good lawn topdressing.

Use in-line feeder system to apply natural bacteria to soil.
Use a garden filter to remove the chlorine. If you cannot find one
on the market, try making your own! Buy a shower filter and covert
it to garden use by attaching it to the hose! Replace yearly the
A Natural spray to use:
Using Compost Tea to control fungus:
- A good strong compost tea can be
sprayed on the effected lawn to control most fungus related problems. Allow the tea to sit
for a few days before using. Add some natural soap (a few drops per gallon) to
increase effectiveness as the soap becomes a wetting agent.
Control your watering.
