The new leaves are pale, indicating a Nitrogen deficiency. This rapid take up of all nutrients means that the existing plants will be experiencing a temporary deficiency know as the “ Nitrogen Drawdown” and so will not grow as well and may even exhibit some deficiencies eg.
#Grass clippings as mulch plus#
The combination of high nutrients plus thin cell walls makes it easy for Fungi and Bacteria to break it down rapidly, especially if the weather is warm as the naturally abundant Fungi and Bacteria will be very active. This grass will contain lots of nutrients from the fertiliser and produce grass with thin cell walls due to its rapid growth.
It will grow rapidly and need mowing often – usually every two weeks. This occurs when the lawn is watered often and fertilised frequently. Nitrogen Drawdown occurs when Fungi and Bacteria rapidly multiply from the presence of easily accessible Nitrogen in the soil forcing them to draw in all other available nutrients from the surrounding soil especially the Nitrogen from ALL sources that would otherwise be available to the plants already growing in that garden. Thus they can become a bad addition to the garden. Personally I find them a useful addition to the garden providing another source of nutrients as they decompose, a cheap and free garden cover and they turn into beautiful soil right where you put them on your garden bed without the usual turning required if you put them into a bay compost system or other above ground composting system.īut…and there is a But….They may also be loaded with herbicides or fertilizers if you have sprayed your lawn to remove weeds or fertiliser to improve your grass growth, if your thing is to have a beautiful lawn.
To Use or Not to Use – Grass Clippings? That is the big question for many gardeners.
