Re: Soil Test…Low PH

If you have 5000 sq ft and put down down 100 lb, of lime you have done only 20 lb/1000 sq ft. Your plan was to do 30 lb/1000 sq ft this fall and the same in the spring. That would entailed putting down 150 lb over 5000 sq ft. this fall and 150 lb in the spring.

Re: Soil Test…Low PH

What sort of debris? If you’re talking about leaves, just mow them and leave them on the lawn all chopped up. Might take a few passes. They will decompose and provide valuable organic matter for the soil.

You likely don’t need to do anything about the calcium.

Re: First Soil Test

Yes, Virginia soil is usually acidic. But there are limestone deposits in western Virginia. I would expect alkaline soil where there is a lot of limestone. Wouldn’t expect alkaline soil in Alexandria but I guess it’s possible.

Re: How do you calculate ppm to 1k square foot?

The test should also include electrical conductivity (EC).

Here is a brief email explanation of saline, sodic, and saline-sodic:

Re: How do you calculate ppm to 1k square foot?

It looks like UC Davis does only research testing, doesn’t provide routine soil testing for individuals. Call the extension number and ask them what labs they recommend and what specific test to request. You want pH, CEC, the cations (like potassium, sodium, calcium, etc.) and phosphorus (an anion),...

Re: How do you calculate ppm to 1k square foot?

I suggest you get a soil test from an established lab like Brookside or Waypoint. They will give you fertilizer recommendations for a whole growing season rather than for just one application. You cannot trust the pH reading from these online companies. https://thelawnforum.com/viewtopic.php?t=16135...

Re: Soil Test…Low PH

November is a perfect time to spread lime. The ground isn’t frozen yet. It will have all winter to make its way into the soil and start reacting. Your plan sounds good.

Re: Soil Test…Low PH

If you used a reputable lab, they should have given you recommendations, including how much lime you need. You can apply up to 50 lb of regular lime per 1000 sq ft in one application. Subsequent applications can be made spring and fall until you reach the total. If you used an online lab like Mysoil...

Re: Wanting to aerate lawn but leaves are dropping

I agree with tgreen . If you kill weeds now and the grass doesn’t establish, you will have bare ground and erosion. Better to keep the weeds you have. In the spring use preemergent but at a rate so protection wears off by August. In the summer you can use weed killer to kill off weeds. Then seed in ...

Re: First Soil Test

Maybe the Indians used to have oyster roasts on your lawn? There are some limestone deposits in western Virginia but generally soil in Virginia tends to be acidic. Your results were so strange I did a search on Alexandria soil and found this 1915 soil survey: https://www.nrcs.usda.gov/Internet/FSE_M...

Re: New to forum / 2021 soil test.

Wait until at least the spring before doing another soil test. If you get lime particles in your sample, it will skew the results.

Re: First Soil Test

I don’t know what to say about this test other than it seems very odd. Normal soil around here does not have so much calcium. I wonder if the sample was contaminated in some way. I suggest calling the Alexandria VA Tech extension office and talk to them about your results: https://alexandria.ext.vt....

Re: Is it too late for Pre-Em?

If you use preemergent now, you must use a rate so that the preemergent will be used up by the time you overseed. Otherwise preemergent now could interfere with the seeding. Personally I would skip it this fall.

Re: Help - What’s happening to my sod?

Do not apply preemergent to new sod. Most advice I have seen is to avoid preemergent for a whole growing season to allow the roots to firmly establish. Preemergents have a root pruning effect.

Have you consulted your landscaper about your sod problems?

Re: Fungus in my reno?

Looks like slime mold to me. Do some searching on slime mold in turfgrass and see how the descriptions and pictures compare to yours. If it’s slime mold, it goes away on its own in drier weather, doesn’t permanently harm the grass.

Re: Starter Fert W/Meso Post Seeding

Here is the label: https://www.lebanonturf.com/labels/2153867.pdf It says a second application can be made 6 weeks after the first one done at seeding. A regular preemergent can be done after a sufficient delay. Here is a list of herbicide delays after seeding: https://turf.purdue.edu/herbicide-dela...
