Solution 1 :
- Lime: Limestone is the most common soil additive for raising pH of your soil to make it less acidic.
- Wood Ash: For an organic way to make your soil less acidic, sprinkle about 1/2″ of wood ash over your soil and mix it into the soil about a foot deep.
Use dolomite limestone to adjust the pH if your soil test shows that your soil is low in magnesium. Pulverized limestone is the most common and inexpensive acid neutralizer.
If the pH level is below 6, the soil is too acidic, and you need to add ground limestone. If the measurement is above 7.5, the soil is too alkaline for most vegetables, and you need to add soil sulfur.
Order your Asparagus then prepare your soil and have it ready when your Asparagus arrive.
Your soil uses limestone and sulfur most efficiently when it’s tilled into the soil to a depth of 4 to 6 inches.
