    I've seen the reference on here before concerning "overseeding" and am not exactly sure what it means. Is this just what it says, that you seed over existing grass or sod, and is it used to get a thicker sod? Someone get me going on the right track concerning this process.

    Assuming my thoughts are right, how successful is this procedure. I have some yards that the grass needs some help choking out the undesirables, and am wondering if this may help.

    These aren't bald spots, just not all good grass.

    Overseeding is the process of spreading seed over existing turf so yes it is just what it says like you were thinking.
    It is used to thicken up thin lawns or to establish a half-way there lawn, it can also be used for bare spots.

    As for weeds, yes, strong healthy grass can and will win the war over weeds but make no mistake, it needs to be strong and healthy. If there exists grass already and the weeds are winning, it is as possible some lime and FERT gives the grass enough a boost to win the war, otherwise a weed treatment may also be in order.

    There are some weeds over which it appears the above is against the rule, such as crabgrass (aka watergrass). But certainly, establishing a healthy, strong lawn would be my first step and it's personal but I'd rather have weeds than nothing and lets get the grass going first.

    Yes, the lawn wins in the end but it is a war lol.

    Overseeding is done by verticutter (slitseeder) or aerator then seeding. If using a slitseeder most will have a hopper for dropping seed in place. Many just aerate then spread seed afterward with a rotary spreader.

    Try doing a google search of overseeding.... You will find many different ways and instructions.

    Soupy: Overseeding is the process of seeding over or through the existing growth. what ever it is. the reason for overseeding can be one of many, for instance if a lawn is thin, diseased or some will do it just to add new plants or to change the type of grass in the lawn.

    Critical issues to overseeding are.
    Seed / soil contact. If you do not get the seed to the soil it will be on top and therefore become bird food. Somehow you need to get the seed to the soil. Aeration and cutting slits are the best way. There are machines out there for this.
    Second is after care. If you do not take care of the new seedlings they will die. After care is critical.
    IF you have never overseeded I would advise you to read up on it first or consult your local Turf Specialist or Extension help at a local university. Also you can call Turfco at 800-678-8201 and have then send you some free books on Aeration and overseeding. They are 1. Why Aerate my Lawn 2. How to get started in lawn Aeration 3.

    All very good info, and thanks to each one who helped. I had a notion about it, but the ideas confirmed and were very informative.

    I was surprised to see this "moved", but I'm sure the "movers" know best. It just seemed like a lawncare related topic to me, but anyway I was able to find the responses and appreciate it. But, I must say, I think more would have been brought out had it been left in the forum that I started it in.
