Lawn Management – Brown spots

This week’s lawn management topic is brown spots, and proper use of irrigation.

This is one of the things most people ask me when they want to transition from chemical to organic:  How much water do I need to keep my grass alive?

Lawn, specially chemical ones use a lot of water–which can be expensive.

But over the past eleven years, I have learned that an irrigation system is not needed when the lawn is organic. For the most part, we rely in Mother Nature to provide all the watering needed during the growing season.

The reason is simple.

An organic lawn does not need as much water.  Because we were let the grass grow taller, and because we introduce the microbiology back into the soil, the need for artificial irrigation is drastically reduced. The microbiology in the soil starts adding organic matter to the soil, increasing the availability of nutrients, and the water holding capacity.

This doesn’t happen overnight.

We start by feeding the soil. Then we apply compost tea to increase the biology in the soil. We let the grass grow to four inches. We leave the grass clippings on the lawn, and we water the lawn when needed. We also apply organic fertilizer.

The end result is an increase of good soil. Roughly one to inches of new soil every season. We need at least 6 inches of good soil to grow grass.

So, how much water is needed for the grass to grow healthy when you follow an organic plan? Just two inches of water per week is enough. 

Do you have an irrigation system? How much do you spend to water your grass?  Would a switch to organic help you save money?

Only two inches of water per week is needed on an organic lawn.
