Color. A healthy lawn is dark green, while an under-watered lawn will possess a slightly blue/gray tint-and almost purple color if the grass is extremely dry. “If you wear polarized sunglasses (that reduce glare), you can notice the subtle change in color of the lawn more easily,” Markway says.
So, an easy way to determine if your lawn is too dry is to take a screwdriver with a 6-inch shaft and push it into the ground. If you can drive it in easily your lawn in hydrated, if you cannot push it in easily or all the way, your lawn is dehydrated.
By aerating the area you'll de-compact the soils which will help nutrients and water to penetrate the soil. Aeration is much easier after a good soak, so if your lawn is already dry, don't try to aerate before the soil is softened up with deep watering. Wetting agents assist water to absorb into the soil.
If you think your lawn is suffering from Dry Patch look for the following symptoms; Irregular patches of your lawn turning a darker green before turning brown. The soil underneath the grass is completely dry, even after heavy rainfall. If you apply water to the dry soil it will run off or pool, but not soak in.
If the grass is dormant, then watering it regularly and properly may revive it. This is why it is important to know if the grass is dormant or just dead. Dead grass cannot be revived by simply watering—it requires reseeding, fertilization, and several other processes to restart growth.
You will also see the difference when you start to water or when rain returns as moisture will revive brown grass. However, it will not bring dead grass plants back to life.
It's natural for grass to go dormant to conserve water during periods of limited rainfall, and drought-induced brown grass should turn green on its own as the weather cools and rainfall increases. You can also restore your lawn by giving it an inch of water on a weekly basis with your lawn sprinkler.
There is no way to revive dead grass, but you can keep brown or yellowing grass from dying out. The best way to revive dehydrated grass is to offer moisture as needed.
Play it safe and wait for the grass to dry before you mow it. If the grass is too wet, you shouldn't mow and if it's too dry you shouldn't either. Remember, mowing is a stressful event for your lawn. If you mow when it's already under stress, such as during dry spell or drought, then it will become even more stressed.
The best time to mow is when grass is dry. When moisture from rain or the morning dew weighs grass down, the blades bend, making a straight cut difficult. You also can slip on wet grass, and the clippings tend to clump and not spread evenly. In addition, disease can spread quickly when you mow wet grass.
Wilting & Browning
Browning, especially in shallow-rooted turf areas, commonly occurs. How do you know the cause of brown patches on your lawn is due to drought versus fungus? Dry lawns turn brown starting at the tip and working back towards the roots of the grass plant.
On the other hand, when you notice drying the grass throughout the entire lawn, there is only one reason for that. It needs water. Once you determine that the lack of water is the cause of drying grass in your yard, you should start watering to help it recovers.
When to Water the Lawn. If you find your lawn has taken on a grayish cast or appears to be dull green, it's telling you that it needs water. You can also check your lawn by walking on it: If your footprints don't disappear quickly, it's because the grass blades don't have the needed moisture to spring back.
One sign you may notice is spots and patches developing in your lawn, or that your grass blades have become shredded or shriveled up. This is typically a sign of a lawn disease festering but can be from other things as well.
How successful you are at getting dead grass to grow back will depend on how long the grass has been dead, but if you're within that 3-5 week period, there's a good chance you're in the clear. Every lawn needs its own special TLC treatment to nurture it back to life.
Many grasses can stay in dormancy for 3-4 weeks without beginning to deteriorate to the point of plant death. When the prolonged period without rain ends, the turf is able to regenerate from rhizomes and stolons.
It is ideal to water lawns about one inch of water per week. To determine how long you need to water to get one inch, place a plastic container in your yard and set a timer. On average, it will take 30 minutes to get a half inch of water. So, 20 minutes, three times per week will give a lawn about an inch of water.
It's your lawn's way of conserving energy and water, Mann explains. The grass will break dormancy and begin growing again when the temperatures and/or rainfall levels become more ideal for it. Note that when dormancy ends, grass leaves that have turned brown won't revive, but new leaves will appear.
The grass plants may appear dead to the naked eye, but deep inside the plant, there is a small area (called the crown) that is still alive. Once this crown gets moisture again, it will come to life and the turf will green up in 10-14 days.
Best Ways To Plant Grass Seed Over Old Grass
Definitely yes! Hand-sowing is the simplest method if you only need to cover a few spots. Take a handful of seeds and spread them over the dead patch, or better yet, involve your kids and introduce them to some basic gardening chores.
Lawn aeration is a great way to help revive brown “dead” grass; poking holes in a lawn will grant the roots unencumbered access to oxygen. Professional lawn-care services may offer this service in the spring to help revive dormant winter grass in time for the summer.
If the lawn does not get enough water it will turn brown and go into summer dormancy. Once the lawn turns brown from summer stress it will take heavy watering for to green back up.
