Water is a question I am asked about all of the time and there is no one answer that fits all. Many municipalities will tell you to water DEEP, once a week and to a depth of 1” or 2.5 cm. Well, that’s fine and dandy but how do you water deep and why?
We’ve seen many turf properties over the decade that are bone dry when the irrigation system is turned on. In these conditions, most of the water runs off onto the street and down the street drain. The reason is that, like taking a dried-out sponge from under your sink and putting it under the tap, most of the water will run off until the sponge is finally wet. At that point it will take just a little water to rehydrate it.
The soil under your lawn is like that sponge. When it dries out it becomes hard and non-absorbent. If your turf soil is dried out, begin rehydration by watering more frequently and more often to allow the soil to absorb the water in stages. Then when it finally becomes hydrated, (the consistency is of a wrung out sponge), you can reduce the frequency.
So this spring, don’t let your turf soil dry out. It will save you money in the long run.
The last word on spring clean up goes to weeds. Pay attention to what weeds come up this spring. Weeds will have a lot to tell you about your soils. How to deal with them will be for future conversations in upcoming blogs.
