    I had my soil test done it came back ph 4.6 in the back yard and 5.0 in the front yard is it ok to put lime down now it is getting into the 90s here. Or should I wait till fall also will you please tell me how much lime per 1000 sf also if you suggest something like 50lbs per 1000sf is it ok to do all at one time or break it up into two applications.

    Do not use magnesium "dolomite" lime, get a product that is calcium lime, solu-cal. Lime any time you want. 50lbs per 1K seems high, don't really know. What does your soil test say to apply?

    Soil test says 20lbs per 1000sf I have sent another soil test off from lesco the one I have now is from scotts here is a breakdown of it. I dont like the test but for 15 bucks at least I konw I need to raise the ph some. I hope the lesco test will give more information. I will also use lesco fertilizers and such.

    Soil pH Value: 4.60 (Low)
    Optimum Levels: 6.00 - 7.50
    Interpretation: The soil is acidic
    Recommendation: Apply granular limestone 20 lb per every 1,000 square feet

    Soluble Salt Value: 0.20 (Optimum)
    Optimum Levels: < 0.60
    Interpretation: The soil is well drained
    Recommendation: The soluble salt level is ok.

    Phosphorus Value: 76.00ppm (High)
    Optimum Levels: 20.00ppm - 40.00ppm
    Interpretation: The soil is high in Phosphorus
    Recommendation: Apply Scotts® Turf Builder® Products according to the product label

    Potassium Value: 165.00ppm (Optimum)
    Optimum Levels: 150.00ppm - 250.00ppm

    That is all you need, apply the lime at the rate perscribed. Lesco soil test will say the same thing only a bit more confusing.

    I deal with CLC labs in Ohio for my soil tests and the majority of the lawns that we test come back with PH levels of 5.1 to 5.3 and recommendations of 65 to 85 lbs of lime per 1,000 sq. ft. It's not a good idea to apply more than 50 lb/1,000 sq. ft. in one application. If your lawn were mine, I'd apply lime at this time at 50 lb/1,000 sq. ft. and do it again in late September at the same rate.

    I agree with HC's advice... 50 lbs per k now... another 50 pbs per k in Sept. pH is something that is sort of a moving target. Soil pH does not want to change, depending on how much buffering it may have. No soil test will tell you how reluctant to change your soil night be due to buffering. I would add the 50 lbs and and the second app of fifty, and retest for pH next january or so. Lime generally takes about 6 months to finish making whatever adjustments to pH that it will, but your's is so low, go with the two apps of 50 and retest.

    pH 4.6 is very acidic.
    Solu-Cal will get you a faster response.
    50 lb. per K is maximum.
