Improper mowing is probably the cause. You’re probably removing too much of the grass leaf at each mowing. You should either mow more frequently so you never remove more than one third of the leaf blade, or you need to level out your yard’s high spots because the mower is cutting too low as it goes over bumps. You’re looking a common lawn problem: iron deficiency. Usually, you’ll find this condition in soils with high pH.

If the grass bordering these yellow areas is a healthy green color and the yellow areas don’t spread, fertilizer burn is to blame. Whenever excessive amounts of these materials contact grass, they cause the blades to dry out and die. You can prevent burn by picking up spilled fertilizer, applying fertilizer according to label directions and thoroughly watering the grass after fertilizing to wash it into the soil. You’re probably looking at Fusarium patch (pink snow mold).

Aim to mow your lawn on 4- or 5-day intervals while it is growing most rapidly during the summer. That way you'll not remove more than one-third of its growth at any given time. Letting the grass grow taller weakens it. White grub worms (larval form of June beetles) devour turf roots (both bermuda and St. Augustine) leaving the grass dead and lifeless on top of the soil. Their prime season of activity starts 6 weeks after the major June beetle flight in early summer and continues until frost.

We typically mow the lawn weekly. We are sometimes able to cut it twice in one week during the heavy growing season. We usually trim markers six times during the growing season. Families are welcome to trim their markers more often if they wish, provided they take care not to disturb the soil. Soil disruption allows for weed seeds to take root and grow.

Optimum grass height varies by region - and by grass type. For example, creeping bentgrass spreads by stolons and should be mown below a 1/2 inch. In fact, if you mow this grass variety too high, it may develop thatch problems. Conversely, Canada bluegrass won't tolerate close cuttings and needs to be kept above 2-1/2 inches in order to survive. Here are some general mowing guidelines for many of today's most popular grass varieties: Recommended Mowing Heights

You should mow the grass at the highest setting on your mower or at least 3 inches. Each time you mow, you should cut no more than 1/3 of the grass height. Note: There are exceptions for some warm season grasses such as bermuda centipede, and bentgrass that grow more dense at lower mower settings.

No. Mowing frequency varies by the season. In the spring, established lawns should be mown as soon as the grass greens and begins to grow. In the summer, close mowing (especially during hot weather) can weaken some grass varieties. As autumn approaches, cool-season grasses begin to grow faster and produce more clippings. Conversely, warm-season grasses begin to slow down. Adjust your mowing habits accordingly.

There could be several reasons, such as an iron deficiency, too high a pH or a lack of iron in the soil. I would suggest a soil test to determine the pH. We offer this service here at the Volusia County Extension Service, 3100 East New York Avenue (Route 44), Deland. The cost is $1 for three samples. We test each Thursday morning, so bring it to the center before then. If the pH is okay, try applying iron chelate in the area. Sedge is an indicator of over-irrigation.

This tell-tale "frog-eye" pattern is caused by several fungi. Called Fusarium blight, this is generally only a problem from June through August. Two of the most susceptible grass varieties are bentgrass and Kentucky bluegrass. Lawns are particularly susceptible to the disease when they are under stress from drought. Once these fungi go to work in your yard, you may have trouble stopping them. Your best bet may be to re-seed with resistant grass varieties.

This is typical of damage caused by white grubs. White grubs are the larvae stage of the June bug. A spray or granular pesticide application in Sept-Oct or March to May should control these pest. Use Dyloxl or Mach 2. Another option is imicloprid which has to be applied in early June so it will be present when the grubs are young. .

It is simply a time issue. With the ability to program the Robomower RL1000 for several mowing sessions automatically, it can easily handle the extra 4,000 square feet using the additional mowing session, all without your assistance

You can generally start mowing 3-4 weeks after seeding your Bermuda lawn. Occasionally if growth is rampant, you may need to mow within 2 weeks after planting. Thereafter, mowing will be required in a range of 3 to 7 days depending on various factors. Bermudas are mowed from around 3/8 inch to 1 & 1/2 inches in height. Lower mowings require more frequent mowing. Height below around 1 inch may require a "reel" type mower to prevent scalping.

Sometimes a person grows a flat of wheatgrass and doesn't use it fast enough. It will start to get yellow. Before that happens, it is better to cut the grass and put it into a plastic bag (with some holes) and then it will keep in the refrigerator for one week. However if one knows he will use it fairly fast, it is better to cut only what one needs for that day to make juice.

The beginning of Vitiligo and the severity of pigment loss differs with each patient. Light skinned people usually notice the pigment loss during the summer as the contrast between the vitiliginous skin and the suntanned skin becomes distinct. People with dark skin may observe the onset of Vitiligo at any time. Individuals who have severe cases will lose pigment over their entire body surface.

You can have acne on any part of your skin where sebaceous glands are found. These are the glands that produce oil for the skin. Most, but not all people get acne on their face, but the skin on the chest and back can also be affected. Acne can also be seen on the arms and thighs, but it's much less common.

Newborn infants are able to see, but as they use their eyes during the first months of life, vision improves. During early childhood years, the visual system changes quickly and vision continues to develop. If a child cannot use his or her eyes normally, vision does not develop properly and may even decrease. After the first nine years of life, the visual system is usually fully developed and usually cannot be changed. The development of equal vision in both eyes is necessary for normal vision.

When used in a signal with solid red/yellow/green arrows, means that permissive (yield to oncoming traffic) left turns are allowed - used when the through signals turn red to allow oncoming traffic to have both a through green and lagging protected green left arrow in order to prevent a "yellow trap", in which left-turning cars already in the intersection are not able to cross oncoming lanes to clear the intersection. http://projects.kittelson.
