Why is the grass in your lawn turning yellow?

There are actually a number of causes: Drought (or not enough moisture) Acidification from dog urine Nutrient deficiency Lowered pH Excess heat from the sun (esp. On several consecutive hot summer days) Cutting too close too often Killing action from too strong a herbicide mixture or from using the wrong herbicide mixture Often when your grass turns yellow it is either dying, already dead or going into dormancy. The things that can and will kill your grass is yellow spots from canine urine, herbicides and sometimes lowered soil quality.

All of the above can kill your grass if it doesn't have the adequate root structure it needs to survive, especially if your lawn has just been layed down as sod. But if your lawn has been around for a very long time (+10 years, the time it takes for a healthy root system to form), it would go into dormancy if the weather gets too hot, there's not enough moisture, or there's not too much nutrients that the grass can get from the soil A newly seeded or sodded lawn NEEDS TO BE WATERED OFTEN, or around once every few days. Fertilization is important as well, as this can be done by leaving the residual lawn clippings, fallen leaves, etc.On the grass for it all to decompose over time and turn into compost for your grass.

Have a soil test done on your lawn too to see what minerals are deficient, and fertilize accordingly. Areas where your or someother dog has urinated can be limed to neutralize the pH of the area; if the soil of your lawn is acidic, then you will have to lime that as well Heat from the sun and drought are two factors that you cannot control. If your town or city has bylaws on water consumption, you may have to bear with a yellowish lawn for a while, but if you absolutely have to water your lawn, water it lightly early in the morning or late in the evening to still give it enough moisture to subsist.

Don't water in the afternoon as it will just be a waste of time; all that water you put on your lawn will simply evaporate into the atmosphere, leaving your lawn more parched than ever As for herbicide, you probably have went a little herbi-crazy going after that clover, those dandelions or other noxious weeds. Either that, or else you used the wrong mixture, spread it all over the lawn, and instead of targeting those nasty weeds, you killed your lawn instead. Often when you are using herbicide for grasses there is a 99.99% chance that it will also kill your desirable grasses.

Too strong a mixture will also do this. Either be more careful or call in a lawn-care professional to do the spot-spraying for you Cutting too close too often will also kill your grass. Use the 60-40 or 50-50 rule, so that you leave enough grass that it will grow back.

When I say 60-40 or 50-50 I mean cut 60% and leave 40%, or cut 50% and leave 50%. For instance, if you let your lawn grow to a general height of 6 inches, with the 50/50 rule, cut the first 3 inches and leave the rest. Or, if you prefer to use the 60/40 rule and have a "tall" lawn of 6 inches in height, cut 3.5 inches and leave 2.5 to grow.

If you go the 80/20 rule and have your lawn looking like a golf course, you could potentially kill your lawn, especially if you don't have the same grass species that the golf course has. Grass species has everything to do with how you should cut your lawn, when to reseed/resod, etc.But back to the cutting, don't cut your grass every day, cut only when it gets to the point that it is over your ankles, which is about 4 to 6 inches in height. You will have to cut more often in the spring when your grass is growing, but decrease the amount of times to cut in the summer.

I wouldn't bother cutting your lawn if it is not growing much particularly in the summer heat and sun, as you may do more harm than good. Cutting once every few weeks is good enough to keep your lawn and its root system healthy Grass depends on its roots for growth. If the root system is destroyed buy over-cutting too often, you will have a dead lawn.

Roots need time to regenerate themselves after the grass has been clipped (or even grazed), and if it is cut too close or overgrazed, the root system becomes shallower, and the grass itself becomes less vigorous, resulting in a thinner stand. Letting the grass recover over a period of a few weeks is enough time for the root system to regenerate. Grazing is the same way.

If you graze heavily but not often, the grass still has time to regrow back and replace and extend its root system. Grazing frequently but lightly will also not kill the grass, provided you make sure that the livestock aren't overgrazing the stand If you live in a climate where the seasons are defined, leave the grass be in the fall. Don't cut it right before killing frost otherwise you will degenerate growth next spring.

Grasses help store carbon and other nutrients into the roots as they mature, and if they are forced to grow after being cut in the late fall, the have to use this storage of nutrients to grow again. They can't get those nutrients back during the winter because they are covered in snow and it is simply too cold for them to grow. And they can't get them back in the fall because it may be too late in the season to properly generate the reserves they need for spring.

If these grasses do not have the reserves come spring, they will not grow properly nor as lushly as before. That's where you have to come in with the fertilizer to give them a boost Lawn maintenance is a science and an art, see. Most of its just plain common sense.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
