[QUOTE="Sheila Cooke, post: 5111880, member: 44294"] "The higher you cut the faster the recovery" is true, and here is the reason why. Plants produce food for themselves and for the microbiome in the soil. Christine Jones says that 30 to 40% of food produced by a plant is squirted out through the roots and exchanged with mycorrhizal fungi and microbes for nutrients that the plant can absorb. Plants can't directly access the nutrients from soil -- the nutrients must be prepared for them. In this symbiotic relationship, life in the soil receives energy from the sun through plants, and plants receive nutrients from the soil through fungi and the microbiome. As the plant matures, it begins to produce excess energy, and it stores this excess energy in its in crown and roots. The next time the plant is grazed (or mowed), if it is severely grazed (very short), the plant has no option other than to draw upon stored energy to shoot up a few new leaves so that it can produce food again through photosynthesis. During this transition, the roots are not fed sufficiently, which is why roots slough off. Additionally, there is insufficient food for the soil microbiome, and there is die off. The attached series of grass growth charts illustrates this. Don't take the number of days as hard and fast -- it is just shown as an example. Actual recovery time will vary based on many factors. To avoid killing off all that life, and to keep grass growth in the fast growth zone (see the Recovery and Growth Curve at bottom of message), it's better to graze/mow taller.
