To Fertilize your lawn is the best way to keep it looking fresh year after year. Watering and mowing regularly would also help your lawn grow healthy. However, There are these top Lawn problems you should be aware of and find ways to solve:
1. Crabgrass - This fast growing and adaptable crabgrass could ruin your lawns if its underfertilized and not been mowed regularly. Not hard to control but timing is always crucial some would apply pre-emergence herbicides when it too late for them to patch on their lawns.
The remedy: an option for spring, is to apply gluten meal. To prevent crabgrass and fertilizers. You can keep crabgrass at bau by feeding proper grasses with ample water and fertilizer. And mow properly. Products with dithiopyr, prodiamine or pendimethalin are typical chemical alternatives. The EPA considers all three possible human carcinogens, however. If you do use them, as with all herbicides and pesticides, be sure to wear rubber gloves, eye protection, long pants, closed shoes and a long-sleeved shirt. And follow the directions very well.
2. Dandelions - They are called a perennial weed that thrive in thin lawns with little fertilizer.Also, they develop a long and thick taproot. Before the flowers mature and spread their seeds, you must kill the the entire root or the plant will resprout.
The remedy: Use a specialized, fork-like tool to pull plants and taproots out by hand. While selective herbicides with a combination of 2,4-D, MCPP and dicamba are effective chemical alternatives, the EPA considers 2,4-D and MCPP possible human carcinogens and says that dicamba can cause reproductive problems. If you decide to use those broadleaf herbicides, apply them in fall, not spring. Use granular products on wet grass, liquids on dry (but not droughty) grass.
3. Other weeds - The Dallisgrass, nimblewill, quackgrass and tall fescue develop into unsightly patches and clumps. They’re likeliest to invade areas that are drier, wetter, shadier or otherwise different from the rest of the lawn.
The remedy: There is no selective herbicide or other shortcut for those weeds. While glyphosate and glufosinate-ammonium are effective chemical remedies, the EPA considers glyphosate moderately toxic. What’s more, both chemicals require multiple applications and must be applied during periods of active growth.
4. Fungus - According to experts, Fungicides are a waste of time and money. The symptoms are: dead grass –not the cause,” says Zac Reicher, professor of turfgrass science at Purdue University. What’s more, that patch of dead grass is likelier to have been caused by your neighbor’s dog than by fungus.
The remedy: Fungus must be diagnosed and treated before grass begins to die a challenge for most homeowners because it’s hard to spot or identify. Instead, look for typical causes such as too much water, improper mowing and fertilizing at the wrong time of year. Then replant the dead area with a suitable grass type.
5. Moss - It is an attractive ground cover spread by spores that many homeowners cultivate. You can kill moss with a spray. A healthy colony of moss in your lawn means too much shade,acidic, compacted, or wet soil; or too little fertilizer.
The remedy: For very shady areas, reseed with shade-tolerant grasses such as creeping red fescue or St. Augustine and mow them high to maximize their light-trapping leaf surface. Also keep trees and shrubs properly pruned. For moss in low-lying or moist areas, water only when you see signs of too little moisture.
6. Too much shade - Most lawn grasses don’t like shade, even “shade-tolerant” varieties. While pruning most shade trees every three to five years is usually a good idea, pruning too often or too much can damage the tree.
The remedy: Replace lawn beneath trees with bishop’s hat, sweet woodruff or other shade-tolerant ground cover as the tree grows and creates more shade. Then use shade-tolerant grasses at the edges of the area. Trim back high hedges. Azalea, Canada hemlock, common boxwood, flowering quince, Japanese boxwood, Japanese holly, lilac, myrtle, privet, rhododendron, roses and winterberry can be cut back as far as needed. Shorten common hedges such as arborvitae, English laurel, firethorn and Japanese yew only a few inches each pruning, and don’t cut into bare, leafless stems. The best time to prune either is in early spring, before the first flush of growth.
7. Compacted soil - The soil in most lawns that usually become hard and compacted, even if you prepared it perfectly before planting. The more you walk on the lawn, the faster the soil compacts. Once soil is compacted, water and fertilizer can’t reach the lawn’s roots, weakening them and allowing weeds to grow. But staying off wet lawns could help delay the inevitable.
The remedy: Soil, or core, aeration is the solution. But it’s a job best left to the specialists. Those professionals use piston-driven aerators with tines that move straight up and down, rather than the lightweight, less-effective aerators you’ll find at many rental yards.
8. Grubs - Those small beetle larvae live in the soil and feed on lawn roots. A few grubs aren’t a big deal. But too many cause irregularly shaped sections to wilt and die. Try to check for grubs by cutting into the lawn near the edge of a brown area and lifting the sod. If it comes up easily, like rolling up carpet, you’ve got grubs. Odds are, you’ll see those milky-white, worm-like creatures with brown heads and three pairs of legs curled into a C shape.
The remedy: Combine Heterorhabditis nematodes (sold in paste-like form) with water and apply to the soil in the spring or fall. Wait a couple of days and reseed or replant any damaged areas. However, chemical insecticides with imidacloprid or halofenozide aren’t effective on mature grubs. So if you choose to use one of those chemicals, apply it in July and August when grubs are immature.
9. Dog urine - Small brown spots surrounded by dark green grass is a telltale sign of dog urine. Nitrogen in the urine kills the grass in the center, where its concentration is highest, while darkening the grass at the edges. Those spots are most likely to show up during hot and dry weather, when lawns are under greater stress. Don’t bother with animal repellents; they’re of little or no use, according to the experts we interviewed. A motion-activated sprinkler system might help discourage droppings, but it won’t distinguish between dogs, deliverymen and welcome guests.
The remedy: Spots of dead grass will often repair themselves eventually. For a quicker fix, cut out the dead spot and fill it in with plugs cut from a strip of sod. Bring a clump from your lawn to the nursery to match grass types. Or wait until grass-planting time — usually in the fall — and sow fresh seed after clearing away the dead grass and loosening the soil.
10. Moles - Those bothersome rodent-like critters tunnel through soil searching for earthworms, grubs and ants. Moles tend to tunnel closer to the surface in spring when soil is moist, leaving a zigzag trail of raised soil. A barrier of chicken wire that extends one foot deep around your yard might help keep them out. But because moles can dig deeper than that and occasionally travel short distances above ground, even barriers are only marginally effective.
The remedy: Trapping a mole is the only way to be sure you’re rid of it. While harpoon-type mole traps work best, handling them is risky and requires skill. Once you’ve spotted an active tunnel, you’ll need to depress the ridge of soil and set the trap over it; the mole will trigger the trap as it moves through the tunnel.Bromethalin, the active ingredient in a new mole bait, is a chemical alternative to mole traps. What’s more, baiting is far more effective than home remedies, according to experts. On the downside, while the mole will die underground, eliminating the need for you to handle and dispose of it, you won’t know whether you’ve killed it.
