If a shovel or a spade is used, dig a V-shaped hole to sample depth of 4-6’’ excluding any thatch, then cut a ½ inch slice off to the side. Do this in different places in the section of the lawn (i.e. front) to be tested.
Mix soil cores for each sample in a clean, plastic bucket. If the bucket has been used to hold fertilizer or other chemicals, wash it thoroughly before using it for soil samples. Let the sample dry well before testing. Place it in a zip lock bag.
Sandwich size is usually adequate.
Soil testing labs are less busy in the fall then they are in the spring, so turnaround time is faster.
Wait until spring to apply any recommended products (except for Mag-I-Cal to adjust pH).
