    Hello,
    I have a question regarding Hydroseeding. My front lawn was completely destoyed by this years hot weather. A friend of mine owns a landscaping and lawn cutting buisness and is planning on hydroseeding this Saturday. He sprayed and killed the whole yard a month ago and it is complete dead. I hate to bother him with questions about this procedure as he is so busy and he thinks I bug him with questions, haha. So, what am I to expect from this procedure? Do you think he will bring in new soil? He told me to mark where all under ground wiring is as I have many lamp posts in yard.

    Hydroseed is generally sprayed on the surface and should be fine w/out a lot of working up of the soil... just like putting down sod w/out working up the soil... but it sounds like he must be going to work up the soil... a month ago was seeding time up here even though the weather was just starting to show signs of relief... it may have been premature to assume it was all dead... what did you have for turf before it was all killed off???

    Best seeding date in the north is when high temps come down to below 85 in August. 8 weeks, maybe 6 weeks before frost. High soil temperature is very helpful. But today's date will probably work out OK. Your average first frost date is Sept 29th.

    Take a few photos and let us know how it works out, OK?

    Hydroseed is usually applied to bare soil--not sure if he is planning to prepare the soil at all (beyond killing the old grass) or what he is planning to do. Its a lot of work to prepare the soil--so we are all interested to see if he can make it work, (and if so learn his secret).

    I am sure some experts would strip the old sod, and haul it away at great expense. Some would then till the soil and add amendments. Some would aerate. Some would just slit seed.

    When Kentucky bluegrass and perennial ryegrass are planted together...perennial ryegrass will dominate due to its faster establishment...unless the mixture is at least 80 percent bluegrass. Keep in mind that hydroseeders use a high percentage of perennial ryegrass...and perennial ryegrass is not suited where temperatures go over 95, (more like 90 if not irrigated). Keep in mind that some perennial ryegrass seed varieties are very poor and some are very good--get the good stuff. Disease resistant, dark green, endophyte enhanced for insect resistance. Get a copy of the seed label so you know what you are getting, the percent weed seed, and the actual varieties included.

    Riggle, you're right: "Hydroseed is usually applied to bare soil--not sure if he is planning to prepare the soil at all (beyond killing the old grass) or what he is planning to do. Its a lot of work to prepare the soil--so we are all interested to see if he can make it work, (and if so learn his secret).

    I would like to hear how it turns out too... :)

    We hydroseed only on fresh soil. I would be concerned if he is going to spray on top of your dead turf. You may get germination but it will probably die off when it has nowhere to root. Let us know how it did.

    It sounds to me since he asked those questions that he is planning to strip the grass of or prepare the soil in some way. Otherwise there would have been no reason for that question.

    I hydroseed a couple of million square feet a year and I have hydroseeded over dead grass like you have a few times but it's not something I recommend. I happened to check this week on a job I did in the spring where they killed the grass on a hillside and I oversprayed crown vetch. The surface looked exactly like yours does in the photo. I probably ended up with one of the best stands of crown vetch that I got all year so it can be done but it is not something I would recommend.

    Someone made the comment about it being late to hydroseed. You are fine with that. I am about 20-25 miles from you and most years can hydroseed for another 5 weeks. Last year my last few jobs didn't come up until spring so this year I may stop around the 15th of October. Actually last year I hydroseeded a new Dollar General store Christmas week but we didn't expect germination until Spring which is what we got.

    It sounds like whoever you have doing it knows what he is doing so I think you will be fine.

    Hydroseeding works for "Dormant Seeding"... no reason why it shouldn't... :)

    Well, he was supposed to start today, but its raining. Got a trailer with a tractor and some kind of attachment on it parked in my drive (see pic). He did mention weeks ago that he was going to bring in some fresh screened soil. I have a roofing company and I hate when customers ask over and over what we are doing, so I kind of hate to ask him about his plans and let him just do his job. However I am interested in knowing a bit what to expect. Thanks for your input.
