    i just lost a GREAT FESCUE LAWN due to brown patch fungus. I thought the grass was just HEAT STRESSED being that in Atlanta, GA (30314) its been in the high 90's with high humidity for dang near 3-4 weeks straight - so its back to the drawing board for me this fall with the overseeding - but this time I'll be prepared ( this is my 1st lawn ever)

    in your opinion whats the best type of lawn sprinkler to use? impact vs oscillating?
    I dont want to invest in an inground system. so I'll use one of the common types attached to a hose and buy a timer but which type of sprinkler would you recommended and why...
    backyard = 50'x25 . side yards = 40x10(each side) , front yard 40x20 = 3300sqft

    Get a good one it will last forever.

    And I don't know if fescue is a good idea in the deep south. Matter of fact I know it isn't.

    Look for a good warm season grass.

    Impacts are very durable. Do us all the favor and invest in a underground system.

    I'm in Eastern NC and I seeded fescue last fall and its been hot and humid here also and NO rain. I've bought a few different sprinklers since then to keep my lawn watered. I started out with 2 gilmour metal head spike impact and they were too heavy for my water pressure. So, I bought an oscillating type and it went back to Lowe's. I didn't really like it. Then I bought some plastic head spikes and they worked good, but then they went bad. I bought 2 Plastic head sled base Gilmour impacts this past weekend and they are the best that I've used.

    Here is the link to the ones I use now:$No=15

    My wife bought me a timer for my birthday and I like this one a lot.:

    Long story short I like impact sprinklers the best.

    oscillating sprinklers have the advantage of covering square areas perfectly. You can set them to flip left or right only, or to water a 10 foot wide area. They are a little slower when set for a large area like the back yard. Typical run time 45 min. Think about professional lawn care--you would have received better advice on what kind of grass to get--and maybe your technician would have spotted the brown patch sooner. Fungicide might have saved it. A more disease resistant Tall fescue might have worked out OK.

    In lieu of a Inground system, if you still have those Gilmore Spikes--replace the impacts if they were too heavy duty with Hunter rotors. Those oscillators would be a good choice for that long narrow side yards. However for the best coverage MP rotors with 100% head to head coverage would best choice, but here again inground system is required.

    MP Rotators on spike bases will cover a pretty substantial area. 4 in the corners of a square will cover 1000 sq ft. 4 MP300 360 spaced 30 ft apart will do 4000 sq ft. These heads will run quite well on household water pressure. They only need 40 PSI to work properly. Hunter PGP heads with the proper orifice will do the same thing. I hate impact sprinklers. They are noisy(not very nice for the neighbors if they have to hear that at 4 in the morning), do not distribute water evenly and that is made much worse by wind. I do a good business replacing impacts and convention spray nozzles with MP Rotators.

    I was in the same situation of wanting a temporary, portable sprinkler system for seeding a lawn last year. It involves a bit of DIY, but Greendoc's and Ralmaroad's suggestions of using geared rotors and/or MP rotors mounted on spikes are much better than any of the standard hose-end sprinkler options, IMO. The MP rotors come in a wide variety of spray patterns, including rectangular in case you have any long narrow strips. The really nice thing about MP rotors is that they have very uniform coverage and maintain a constant precipitation rate regardless of the pattern. With 100% overlap, any MP pattern will apply approximately 0.4in/hr. Using a basic metal spike with flow-through hose connections, a 1/2" pipe nipple, and a standard 4" pop-up spray head in which to install the MP rotor head, it costs about $9 per sprinkler. For larger areas, the geared rotors cover more area with less sprinklers and provide a wider range of adjustability in each head, but require nozzle changes to match precip rates of heads covering different amounts of area. The Hunter PGP heads come with 12 nozzles to provide a wide range of coverage and precip rates and can be mounted on the same basic metal spike, with the addition of a 1/2X3/4 threaded bushing. The spike mounted PGP sprinklers end up costing about $11 ea. A geared rotor does everything an impact sprinkler can do, but works a lot smoother, makes almost no noise, and comes with a full selection of nozzles to meet your needs.
