Knowing your Lawn - The Grass Guide

Grass Anatomy 
Only a select group of 50 species are suitable for lawn use. All grasses share the same basic structure. The crown is the "brain" of the plant. If the crown is cut the grass will die. The crown is also in charge of sucking up water through the roots to fuel the process of photosynthesis. This gives the plant energy to stimulate new growth. Stems and nodes hold each grass blade (academically, known as the leaf). When the grass is cut, only the leaf should fall off (1/3 of the stem) otherwise the plant will become stressed.

Lawn Reproduction 
Grasses differ in how they grow and spread. If the grass leaves become long enough, all species can generate through seed germination. Routine mowing prevents this from happening. Instead, the grass can reproduce in one of three ways: Rhizomatous grasses create new growth at the end of underground stems, called rhizomes. Stoloniferous grasses produce new plants at nodes along stolons, essentially rhizomes that creep aboveground setting new plants down into the soil. Clumping grasses don't send out stolons; they grow new stems called tillers, directly out of the crown. Homeowners like stoloniferous and rhizomatous grasses as they tend to fill out more quickly and fully making for a lusher lawn. 

Cool Season Grasses
Since we only service Northeast Ohio, we have included a chart for cool-season and transitional grasses. Cool-season grasses grow best in colder climates where the temperature is between 60 F and 75 F and require a steady supply of water to grow best. These are average spring and fall temperatures in Ohio, and thus cool-season grasses will need cut more at these times.
