Spread Lime to Adjust pH Levels in the Beds

Yard

9/20/2020 – Given the light rain from Hurricane Sally and the drizzle the past two days, the soil is saturated. Therefore, today is a good day to take pH readings using the meter. The readings are listed below.

9/28/2020 – Spread the lime cited in the table below just before the first cold front blew in this afternoon. We got 0.39″ of rain to start washing in the lime.

From SFGateAccording to the University of California Vegetable Research and Information Center, the rate of application to raise the pH level two points in 1 square foot of garden space is 4 tablespoons of lime. [¼ cup]

To Raise pH 1 point:

1 SF2 tblsp
4 SF – 2’x2′½ cup
8 SF – 2’x4′1 cup
16 SF – 4’x4′1 pt.

The quantities applied in each location cited above in the “Spread” column were set for daylilies as being the center point of a 2′ x 2′ area; i.e. 1/2 C if the adjustment needed was 1 point. Larger areas with more plants were addressed similiarly.

The amount spread was intentionally not the full amount for the larger areas. Next March the readings will be retaken and more applied if needed.


From Baker LimeHere, approximately, is how much limestone you’ll need to raise 1.0 pH level for every 1,000 square feet for the different soil types:

  • Sand: 25 pounds
  • Loam: 75 pounds
  • Clay: 100 pounds
