Your Bermuda grass lawn will prepare itself to go dormant with the emergence of cooler nighttime temperatures. The plant's proteins will begin to change their cellular structure as it prepares for its long winter's nap. The plant will begin transporting carbohydrates and other sugars from the grass blades to the stems and finally to the roots and rhizomes.
Following the first hard frost of the winter season, the visible vegetation will turn brown in dormancy. Remember that your grass is still alive and that the discoloration is a natural part of its life cycle.
The spring and summer months are the time when Bermuda grass shines.
The Bermuda grass will begin growing new shoots and greening up your lawn in the early spring months. Depending on your specific geographic location, this can occur anywhere from early March to late April. The air temperatures average more than the required 50°F for seed germination and sprouting.
The late spring months, late April through May, will see temperatures begin to consistently climb into the 80's. This is your Bermuda grass lawn's cue to kick the growing into high gear. You will begin to see healthy growth that is dense, lush, and vibrantly colored.
Through June and July, the Bermuda grass will begin to feel like you are mowing the lawn every other day. Its growth is aggressive and thick. With an established lawn of this warm-season grass, dealing with invasive weeds nearly becomes an afterthought. The rate and health of the growth pattern of your Bermuda grass leaves no room for weeds to take root. You may find the single straggler here and there, but you won't be dealing with a weed problem. Your vibrant grass has handled that the natural way.
As the summer winds down and the cooler temperatures of the autumn months begin to settle in, the unstoppable growth of your grass will begin to slow down. Even the slightest drop in temperatures will affect the growth habit of this sensitive plant. Its time to shine was through the scorching summer months. It grew strong and healthy even through extended dry periods. Although Bermuda grass is better suited for cooler temperatures than it used to be, at the end of the day it's a warm-season grass that cherishes its time in the sun.
Although this lawn grass will continue to grow as temperatures drop, its primary objective is filling up its nutrient reserves within its roots and rhizomes to settle in and nap through the winter months.
