Fall feeding confusion
I switched to organic lawn care a couple years ago and the soil improvement and overall look of the lawn is great. Iím trying to learn a little more about fall feeding for cool season grass.(live in CT)
I understand that I am feeding the microbes, not the grass and I also understand the microbes donít feed in the cold weather. This means I have to make sure my little guys are actively feeding when I do my last big N fertilizer.
I think I should feed a slow release now (alfalfa, SBM, Ringer, Milorganite, etc, etc) but if I apply again in Nov the microbes will not be dormant and not feeding.
Any advice on an organic fall feeding schedule?
Thanks

Microbial activity will slow down as it gets cooler in the fall, but there will still be some microbial activity. You also have to remember that the late fall fert/winterizer is more food for next spring. The turf will store nutrients it can and come out of dormancy quicker next year. I don't know how cold it is in Conn. come November, but an application now and 6-8 weeks is probably what I would go with.

We were just discussing in another thread about the benefits of composting during the dormant seeding timeframe... Nov. for us...

Actually once the ground freezes synferts don't work either... Remeber also, that what raw materials you apply in Sept. will likely not be Fertilizer until Oct/Nov anyways...

Why? Nutrient availability will vary from immediate to slow release for your "raw" materials.

Makes sense, thanks. I'll feed this week as normal and again in 6 to 8 weeks. I've also read about the last feeding should be very high in N.

Any thoughts?

The turf can only store so much N before dormancy. The rest will run off. That's one of the debates between the organic vs. synthetic guys that put down 46-0-0 urea as their last app. How much ends up in the water supply?

and how much feeds snow mold depending on where you are

if you in an area that can get snow mold DO NOT use N late in the season

Alfalfa and soybean meal feed the lawns directly? don't they have to decompose?

I kinda though this wouldnít be such an easy question. Feeding now makes sense; no problem with that.
If the logic is feeding in fall is the most important Iím still not sure how to do this or maybe this statement is not correct. I know I can use synthetic but I donít want to harm all the work I have been doing to go organic.
Seems to me if I feed organic to late in the season I run the risk of either run-off or mold. If that is the case it would make more sense just to wait until spring to feed and make Sept the last feeding.

"Runoff" is no more a threat in October than in July... It all depends on when the cloudbursts occur... Frozen turf is a different story...

Just be sure that all of your organic matter is in the soil and protected by the roots of the plants, so it doesn't wash over the top of the terrain.... and you'll be fine...

Undigested organic material sitting on top of the soil, is really made evident by the snow, and by the sediments at the bottom of the regional drain... Usually a swamp, lake or stream... common sense makes sense... :)
