If you watched that short video then you know that two of the most obvious ways to encourage deep root systems in lawns everywhere is to irrigate deeply and infrequently. The Most Obvious Ways To Make Grass Roots Grow Deep In short, you want your grass roots to go as deep as possible so that lawn care is easier for you to accomplish throughout the season and so that your lawn looks better all year around without the application of dangerous products to you, your family, or your animals.īefore we consider all of the special stuff we can do to encourage strong rooting let’s first quickly make mention of the most common and obvious things people do and teach on the subject of root development.
Can be fertilized at higher rates but less frequently.Can stay green and growing further into the Fall.Can stay green and lush for a longer period of time when faced with heat and drought stress.Can benefit more from the mycorrhizal fungi that coexists within the grass’ roots and extends their reach.Can benefit more from the beneficial microorganisms that live in your soil.In most cases a grass plant with a deeper root system: Basically, keeping a lawn that has shallow shallow roots healthy is going to require a lot of micromanagement on your part to keep it looking good.
WE NEED TO GO DEEPER TIPS FULL
Shallow root systems show themselves off as with surface foliage that is simply less efficient in pretty much everything – the plant itself doesn’t perform up to it’s full potential. This in in contrast to the CEC, the holding capacity of the soil itself which is an entirely different topic for another day. But there a few other factors that can enhance their development.Ī smaller root density under your soil’s surface also impacts the holding capacity of the grass plant – meaning it can hold smaller amounts of carbohydrates through periods of dormancy, it can uptake fewer nutrients at any given time, and it can retain less water overall. By watering deeply, core aerating, and applying bio-stimulants on a regular basis grass roots can be encouraged to put on deeper and wider growth without the aid of excess phosphorus. Most root systems for all grass types can grow much deeper than the topsoil found in typical residential lawns. When you fertilize lawns that have shallow root systems you are far more likely to waste nutrients due to leaching and denitrification simply because water more easily transports nutrients below the root zone of the grass plant… and if you only lightly water those nutrients in more of it is lost to the atmosphere and through oxidation. Lawns that have shallow root systems typically need more water, more frequently, and they are more susceptible to stressors like high foot traffic, extreme cold in the winter, extreme heat in the summer, as well as extended periods of drought or irregular irrigation.
