mold (I think) on grass, how to approach this?
I had over-watered (twice daily, must've been too heavy) when I sowed my most recent seeds (annual rye seed, for overseeding my central FL, bermudagrass lawn).

There's what look like cobwebs on some spots, and some spots actually have the grass stuck together :( . I've finished letting all the seeds germinate, and am currently acclimating it to 1X weekly (I've been reducing from daily smoothly).

I figured once I stopped the 2Xdaily watering it'd *hopefully* go away, but I'm at 1 watering every third day now and it's still going!

Should I just cut water really hard, like drop straight to the once/week? Or are there products for this?

I would keep cutting back on the watering for now and see how that works. There are fungicides available, but they're usually a little pricy for a quality one. I'm not sure what's available in your area or what restrictions there might be. The best way to get rid of mold is to change it's environment, so I would continue to work on watering modifications ( unless the turf is starting to become damaged).

Do you water at night? Watering at night can actually promote the growth of molds and fungi. The best time to water is in the early morning, heavy enough to saturate the ground. This allows the water to get to the root system but also allows the gentle morning rays of the sun to dry the blades of the grass and not allow molds and fungi to grow. I would cut back to one watering a day in the morning and treat the worst spots of mold and fungus that you have now with a quality fungicide. You can find tons of info on the web about molds and fungi and what they look like. Find out what you have and treat it appropriately.

Good luck!!:thumbsup:

It's the nighttime watering, I'm very guilty of that!! Honestly, 9/10 of my waterings are wrapped up as it gets dark! Okay what you said makes a lot of sense.

I have cut back a lot on the waterings but think I really made a bad choice by going with the annual rye seed <opposed to perennial>, it was all they had so I just went with it. We had some hot days here, and I have big patches that just look burnt!! Lawn's fertilized, not overfertilized (I usually aim around 70-80% of label recommendations and use a higher % of slow release nitro), watered properly, and some spots just aren't making it very well!

This is lawn attempt #4 I believe, I'm not stopping til I have a golf course lol! Looks like spring will be #5, my dormant bermuda will be coming back but I'm gonna switch I wasn't impressed with bermuda.

You really don't need to water when overseeding before winter.
The temperatures are far too cool, even if you don't water the soil never really dries out, that is, unless you're down under.

Your problem won't go away likely until late spring to early summer, but don't worry about that part because patience and time will take care of that but you need to stop watering completely, now.

joeyboy 12-29-2007 12:34 PM

stop watering completely on a FL lawn? Won't that kill the lawn, or at least make it significantly lower quality?

Also - you're saying my rye seed (overseeded on a FL lawn) didn't need waterings to germinate?

Don't stop watering. Soil conditions dictate soil water concentrations. If you have sandy soil conditions, which from some of our last conversations you do, then your going to need to water regularly. Just back off a little on night waterings. Also there are all types of insects that can cause webbing in the turf which can be mistaken for mold when it gets wet. If there's no actual visible damage on the turf ( dying-out, yellowing or rotting) then you're fine. Pourus soils like sand will percilate water much quicker obviously than soils that have more clay or loam or any humus materials. Our clay soils here in nothern IN. get saturated in the spring and fall but get rock hard dry in july and august. Your over thinking this. Talk to a couple of your older retired neighbors and see what kind of watering regime their on, I guarantee you that many of them have it down to a science! By the way, how's your self-propagated tropical doin'?

joeyboy 01-01-2008 04:45 PM

Oh I'm definitely not stopping the watering! I was questioning the logic behind that suggestion more than anything :)

I would talk to some locals, but the thing is that my lawn is already better than most lol, I guess I'm just aiming for golf course style you know? For instance, an older lady on my street has been here for decades, has scott's come by frequently for chemical stuff, and a landscape crew there regularly - my lawn is far better than hers (although half the time I look at hers and wonder what she's even paying them for...). You are probably right though, I'm overthinking it, but it's just because I'm aiming for such a perfect turf, I just have a thing about lawns I guess haha! There are some people nearby who have excellent lawns, I really need to talk to them to see what they're using because some didn't even seem to have that period between summer/winter grasses, I dunno how they pulled that.

About that palm, it's... okay? I think so anyways! I have it in soil now and those big, chunky roots thinned out a lot and got some smaller hairs coming out of them. I actually just saw it's trunk/roots yesterday (got my hands on IBA/rooting hormone, figured it could help :) ), and there's a bunch of bumps on the bark right above where the first roots were poking out from which I'm almost sure are new root growths.

It's crazy, I never had a clue I like gardening/plants til I started messing with them earlier this year. Never really cared for plants at all, now I'm anal about my lawn, I've got this whole nursery setup (tons and tons of propagation attempts from all sorts of different plants/cuttings), and am waiting on my first attempt at aerial layering to start rooting (I'm trying for a ~4-6' long, ~1.5" thick orange tree branch. Unsure what I'm gonna do with it, either a random bonsai for fun or just replant it for more/larger plants in the yard).

I know what you mean, I took a job working for a tree company when I was 19, the first time he got a landscape job I built this set of timber stairs with the co. owner, man I loved it and went home and started ripping out the huge overgrown shrubs in front of our home! Next thing I know neighbors and friends wanted me to do stuff for them. Went into a 2yr. Hort. program at our local college and now at 42 I still can't get enough of it! My wife is about to kill me because I'm spending so much time talking to you guys, than I am on this home reno I'm supposed to be getting done (I'm on my winter break).

joeyboy 01-01-2008 06:11 PM

haha same here! I get the urge to go check my lil nursery out, or something on those lines, and have to mentally stop myself, "gardening /= working on the renovations!!"

timber 01-04-2008 07:48 PM

I went back pretty far into some of the past threads and you've done a lot of work!. That curbing was excellent! We have a couple of small companies up here that do something called curb-lawn edging, where they take a small machine and fill it full of concrete and extrude multiple types of curb profiles. I've subbed it out from one guy quite a bit. Yours looks every bit as nice! Keep me informed on your nursery production.

joeyboy 01-06-2008 11:15 AM

haha will do!!

About those edgers, I actually am in the middle of doing the last landscape bed, the dreaded one!! It's centered in my driveway (half circle driveway), so it's both an arch, and it's on a steep slope! Real pain! I did the straight part the past 2 days and am about to do that arch, wish me luck lol!

Overall though, I'm pretty close to finishing everything I set out to do. This place needed soo much work, but it was at a great price and I wanted to do all the renovation stuff myself. The place is night/day different from when I got it now, it's great!!

timber 01-06-2008 06:46 PM

Well, send more pics 'cause I need a lot more motivation! This place is tapping every ounce of anything I got left!

joeyboy 01-07-2008 10:34 AM

check your pm's!

I've read this post and the other one, and bermuda lawns should flourish in Florida with virtually no maintenance. I suggest aerating your lawn after your ryegrass begins to check out, since the mulch has created a barrier over the sand. And verticut your bermuda once it starts actively growing to get it to spread laterally. Both machines are easily rented. Feed bermuda at 1 lb/N per 1000sf first two months, then slow down to a slow release at maybe 1/2 lb N/1000 every 3 months. I don't know exactly what fertilizers you have used, but each has a different mode of action based on the nitrogen sources. Root growth wants Phosphorus, and building the strength of the grass use ferts high in Potassium.
