If your lawn is looking thin and bare, or just overgrown with weeds — you probably need to give it some extra care. Justin Cave of HGVT's ground breakers is here to show us how to tackle some tough turf problems:

1. WeedsEvery lawn has weeds, some more than others and it's obvious. The most common form of weed problems is crabgrass, dandelions, tall fescue and bluegrass, which appears clumped together or in unsightly patches. It's a result of lawns that are underfertilized or mowed too low. Some weeds are likeliest to invade areas that are dryer, wetter, shadier or different from the rest of the lawn. Controlling it isn't hard, but the timing is crucial. Many homeowners apply herbicides in late spring or summer when it's too late for them to do any good.

2. Bald SpotsIf you see bald spots and bare patches, it could be due to you cutting the grass too short and too early in the year. Grass should be at least 2 inches long before it gets its first cut.

3. Insects and grubsInsects love to live and feed off of grass. Most of them will devour the grass in circular patches. One of the most common insect problems is grubs (pests in grass) - they damage grass by chewing off the roots near the soil surface. Symptoms include thinning of grass -- Early symptoms include gradual thinning, yellowing, wilting and the appearance of scattered, irregular dead patches.

4. Too much sun and shade Too much sun can dry your lawn or leave it with dry patches, especially if you don't water it regularly. But too much shade can also be a problem. Most grasses don't like shade, even "shade-tolerant" varieties. You should prune your trees to get rid of shading, or replace the lawn beneath the tree with bishop's hat, sweet woodruff or other shade tolerate ground cover.

5. Lawn maintenance Lawn maintenance or lack of there care can cause grass problems. Remember your lawn is like a car. It requires regular care, fertilizing and mowing. It has nothing to do with how much time you've invested in your lawn, it's more about how and when you maintain it.

1. LawnLawns require a great degree of maintenance, and one of the most common problems is cutting it too short and too soon especially in hot weather. This can cause problems, like opening it up bald spots, insects and other disease. If the lawn is too short, it cannot retain moisture and you'll have to water it more regularly or it will start to turn brown.

2. Lawn mowerUsing the right lawn mower is an important part of maintaining a nice smooth lawn, and it's well worth the investment. Some mowers don't come with a grass collection bag -- this is fine if you're cutting the lawn regularly. In dry weather leave the grass cuttings on the lawn, so it can help prevent it from drying out. This will save you from watering the lawn. It's best to buy a mulching lawn mower with an attachable bag - you can use the leftover grass clippings as additional lawn protector - simply sprinkle it on your lawn.

3. Lawn blades
Do not use a lawn mower with dull and bad blades, that will give you an uneven cut on the lawn. If you are using either a rotary, cylinder or a hover mower with a metal blade, consider having the blades sharpened at regular intervals. This will give you a better quality cut to the grass without tearing it.

4. FertilizerFertilizer helps maintains a healthy lawn -- Many lawns have poor quality soil, so you need to add fertilizer to give it basic nutrients.The rate, application and frequency of adding fertilizer on your lawn will affect it's color, growth rate and density. Lawns that are fertilized infrequently tend to end up looking thin and have weeds. If you have kids or pets, Justin suggests using organic because it is safer and has fewer chemicals and additives.

5. Weed killer & crabgrass problems

Every lawn has weeds and it's merely impossible to remove them 100%. However you can control the amount of weed that grows on your lawn by using weed killer. If you don't have time to spray the chemicals on the weed patches, then you can simply remove them the old fashion way - just bending down and pulling the root out of the ground.

Crabgrass is a lawn weed which reproduces by seed. The best way to kill crabgrass it to apply a herbicide weed killer at the right time.

6. Grass seedsThis is the last step to maintaining a problem lawn . You want to continue to spread grass seeds in your yard and cover any bare areas or patches. Give it a good raking over, put down a layer of dirt and spread the grass seeds. Make sure you keep watering your lawn everyday.
