Pac. NW lawn renovation...
The usual...long time lurker and first time poster.
Unbeknown to the forum, you helped with the purchase of a Stihl FS250R. Awesome trimmer for my 13 acres.
Anyway, to the chase...
I'm a year into my 'new' purchase of home and some land. I have sufficiently repaired all dry-rot to my home and its foundation (short sale) over the past year and have now started focusing on the neglected lawn.
What I'm dealing with...
1" thick, heavy moss
POA-type grass in large, round sections
heavy infestation of dandelions
various other types of weeds & weed grasses
What I've completed...
Iron solution- Moss Out, liquid applied at 3 oz. per gallon
Dethatching- pull type
Aeration- non plug type, spike aerator, that my father built. A pretty good spike aerator that holds about 20 gallons of water, when full, to give the unit some weight in compacted soil.
Sweep- pull type, to pick up the thatch, moss, and pine needles.
Soil sample- sent off last week, expect it back @ end of this coming week.
Size of immediate lawn- approximately 25,000 squ. ft.
After dethatching and moss treatment, not much is left regarding 'good' grass. Looks like rye and fescue. The moss + POA concentrations in places has absolutely devastated quite a bit of the lawn. I just have raised, dead islands of POA after the moss and thatch has been removed. The pull behind thatcher isn't the most practical but "its what I have." I have even went behind, in places, and hand thatched left over moss that wasn't removed.
I'm a bit overwhelmed with what to do. Every avenue to 'correct' things has a down side and with such a large lawn (in total probably 50K squ. ft. plus) I feel like my hands are tied. Yeah, I removed some moss but now that's just open space for dandelions to seed. Sure, I could spread some seed but not all the moss is out and will my thatching and aerating be enough to get the seed to stand. If I put out a fall fertilizer, will it even matter. So, I turning to this site for some feedback. I know I'll probably need some lime application but I'm waiting for the soil sample to come back on the Ph.
I'm worried most about the dandelions. I've got two adjacent fields that are just a dandelion haven. Long-story-short... some of the property is in timber and it was just logged 4 years ago, with no re-plant of trees. So the open ground just became a cesspool. So I'm not even sure a healthy and hearty lawn will be able cope with the 'snows' of 'lion seeds when the wind blows.
So, in addition to any good natured suggestions or blatant statements that, "...you're screwed," I would like some help/ answers on the following.
1.) Where do you find grass seed at a decent price? I've been by my local farm store/ co-op, nursery, ect... but the best price I've found is a rye/fescue blend at Home Depot. 50 lbs. for $99.
2.) Regarding a pre-emergent. Can anyone list one, that I can buy in some bulk? (I'm almost to the point of buying a 250 gallon 3pt. mounted sprayer with boom arms to Round-up the fields and re-sowing them.)
3.) Where should I start, in the grand scheme of things, for this lawn renovation? Seed, 1st? Lime, 1st? Fertilizer, 1st?
P.S.- I sprayed the Moss Out (Iron solution) about 2 weeks ago and according to the manufacturer, I should not seed until 3 weeks have pased. I'm located near Vancouver, WA, across the river from Portland, OR.
Many thanks for your time and feedback,
