Asking a bunch of lawn wackos whether you should hire somebody to take care of your lawn is probably not going to get a lot of endorsements for the lawn service. I used a lawn service for the first year I owned my house and my thinking was much along the same lines as yours. I'd get a professional service to get rid of the weeds and get my grass healthy and after that, I'd be able to do it on my own. I think they said that they used a specific set of chemicals that they sprayed that was tailored to my lawn and its needs, but the truck that they brought around had a big tank on it and they used the same tank on every lawn. When they would come by, they'd leave a notice on the door with recommendations for how often to cut, water, etc based on the conditions they noted in my lawn. But it was the same every time, regardless of the temperature, rainfall, etc. To top it off, the weed situation was no better than before and may have even gotten worse. I also wasn't really comfortable with the little flags they'd put out telling me to keep children and pets off the lawn for a minimum of X days because of the treatments. So I took matters into my own hands. I read things from the extension offices and started doing things that are pretty close to what gets recommended around here. Things started improving. Then I found various lawncare forums and things got even better. One humorous (or maddening?) thing happened a few years after I stopped using the lawn care service. A sprinkler head broke and a section of the lawn went dormant because it wasn't getting any water (the only water lawns get here is from sprinklers). One of the lawncare services pulled up and told me that I had a serious grub problem and needed to treat it right away. They went out to the area that was dormant and started pulling up sections of grass and telling me that it was due to grubs. I knew it was because of lack of water and suggested that as the cause, and they started launching into an explanation of why they knew that wasn't it. I then turned on the sprinkler in that section and showed them that it wasn't working, but they still tried to tell me it was grubs. Anyway, the main things you want to do are the following: Water deeply and infrequently. Apply an inch of water a week, but only water once a week if you can (in the desert, I often have to water twice a week, or once every 5 days, anyway). Adjust the amount (or the frequency) you water for any rainfall. This has a couple of benefits. First, it promotes deep roots, so the grass can better deal with periods of drought. I call grass a lazy plant, because it will only put down roots as deeply as it needs to for the water it gets. If the top inch of soil is always wet, the grass will have roots that are only an inch deep. Second, letting the ground dry between waterings will discourage weed seeds from germinating, because they need moisture to germinate. Mulch mow and mow at the highest setting of your mower and never cut more than 1/3 of the blade at one time. Mulch mowing returns water and nutrients to the soil and improves the health of the soil. It doesn't contribute to thatch and can actually contribute to getting rid of it. Mowing at the highest setting helps to make the grass stronger because it gives more surface area for photosynthesis. It also helps shade the surface so the roots are better able to deal with heat and drought. Also, it helps keep weeds from thriving because the weeds need sunlight. Fertilize once in the spring and twice in the fall. If you're using weed killers, don't use the weed and feed products (another reason I don't like the services--the one size fits all means they fertilize and kill weeds at the same time). Instead, spot spray weeds that you see sprout up. As for the lime, did they do a soil test? If not, there's no way to know whether lime is needed. Some areas tend to have low pH soils, but you don't know what the prior owner did. The prior owner may have applied lime regularly and heavily and raised the pH too high. If so, I wouldn't do anything to lower the pH because that will happen anyway, but you need to know if it needs lime before adding it. I guess my comment on the grubs is similar. Do you have grubs? If not, the grub treatment makes a lot more sense for the lawn service than it does for you.

Possibly some form of grub/caterpillar/beetle, which may be the larvae of sod webworm. Sod webworm and June bug grubs are frequently a problem in the sunny part of non-irrigated lawns. The new formulation Grubex needs to be applied as early in the spring as possible, as it's less soluble than other forms of grub control. So you may not be getting the grub control you assume.

Can I add something? For the needs of the grass, who cares water 1/3" 3 times a week or all at once one time a week. If you have the ability to water the lawn, why worry about attempting deep root growth for drought resistance...there will be no drought if you can water regularly, right? BUT If you keep that top 2" of soil always moist, the grass will be happy, but so will the weeds that do not have deep roots. Since my KBG has matured, I barely water. I wait for the grass to stress for a day or two, then hit it all night with about an inch of water over ten hours. The weeds have disappeared, and I can go 7-10 days or so without rain or water. Most weeds are shallow rooted and can't withstand dry soil conditions for several days. We all have different soil types, grass types, and enviromental conditions to contend with so no two people can expect to have the same schedule work for them. There will be adjustments in watering frequency and amounts needed. I still think it helps to keep the top layer dry to control weeds and prevent fungus and disease as well. Oh well, whatever works best for you right?

Know your enemy : Identifying grub damage Symptoms of white grub infestation include wilting of grass in patches, eventually turning brown or dying, sod that pulls up easily, in one piece, with the white grubs then visible underneath, feeding on the roots. Increased feeding activity of birds, moles, raccoons,etc. are another sign, you may notice holes in the sod where critters have been digging. The damage is most noticeable in Fall or in dry spells, though serious infestations may be visible in Spring. Dead brown areas can have other causes, such as pet urine, improper use of fertilizer or insecticide, turf diseases or improper mowing, so be sure to identify the problem before trying to treat it! In the case of grubs, if the insects are not easily visible just under the turf, there is no point in treating for them. The usual suspects.... The white grubs you will find feasting on grass roots are the larvae of several members of the beetle family, having an idea WHO you're hosting helps in controlling them. All are fat white C-shaped grubs, with brown heads and six legs, but the larvae of the May or June beetle can easily be 2" in length. This species can remain underground up to four years before becoming a winged adult, so timing of chemical controls is not as crucial, though they must be applied when the ground is warm enough for the grubs to be actively feeding. Japanese beetle larvae are smaller, about 1/2 inch, and have a noticeable V-shaped pattern on the 'raster', the dark bristly area at the end of the abdomen. Japanese beetles complete their life cycle in one year, laying eggs in mid-July which hatch in early August, chemical controls should be applied at that time while larvae are most susceptible. Masked chafer grubs are similar to Japanese beetle larvae in size, but lack the V-pattern on the raster.Unlike Japanese beetles, the adults of this species are short-lived, and do not eat while in the winged state. Their life cycle is similar, with August being the time to apply chemical controls. Dates given above for applications are most applicable for Zone 5, your local County Cooperative Extension Service will be happy to help you with timing treatments in your specific area. Any pesticide you choose MUST be labeled for use on white grubs, and label directions MUST be followed exactly. Preventing grub infestations: biological controls There are a few natural controls available to treat your lawn BEFORE grubs become a problem. Milky spore disease, which is most effective against Japanese beetles, and to a lesser extent against May/June beetles. The bacteria that cause the disease affect only white grubs, and after proper 'inoculation' into a lawn area, remain active in the soil for years. The bacteria need to be present in the soil BEFORE the grubs begin feeding to be most effective, as the disease can take months to kill established grubs. Beneficial Nematodes are microscopic, nonsegmented worms that occur naturally in soil all around the world. Steinernema carpocapsae and Steinernema feltiae prey on ants, termites and the larval and grub stages of various beetles, weevils, armyworms, cutworms, chafers, webworms, borers, maggots, fleas, fungus gnats (sciarid flies). Once they are released, the nematodes seek out host insects and enter their prey through body openings and emit an endo-toxin that results in death for the host insect within 48 hours. The nematodes reproduce and their offspring feed on the insect cadaver and emerge to seek out new hosts. Nematodes are easy to use. They are shipped in a formulation that you mix with water. The solution can be applied using a watering can; hose end, backpack, or pump sprayers; or through irrigation or misting systems. Always release early in the morning or late afternoon when temperatures are cooler. Generally, 1 vial of Beneficial Nematodes will effectively treat approximately 900 sq. ft. of conventional garden rows. Make releases every 3-6 weeks or until infestation subsides.Nematodes can be stored in the refrigerator (do not freeze!) for up to 2 months.
