Collect a soil sample and submit it to a soil testing laboratory for a more accurate and complete diagnosis. Use a trowel or soil auger to collect a sample 4 to 6 inches deep. Augers are easy to use and are simply inserted into the ground. If using a trowel, dig a hole the correct depth and remove a 1-inch-wide sample from the smooth side of the hole. Collect samples in early spring or late fall to allow time for any soil amendments to take effect. Also submit samples whenever you notice any problems in plant growth. - 3). Use a plastic bucket to collect the soil samples. Keep your samples from each unique garden area (e.g., flower garden, vegetable garden, lawn) separate and submit them separately. Randomly collect about 10 or more soil samples from within each unique garden area and mix them together in the bucket.
- 4). Take about a 1/2-lb. sample from each bucket and place them in zip-top plastic bags. Label them with a waterproof pen. Check with the soil testing laboratory you are using to find out what type of information they want you to record.
- 5). Mail the soil samples to the soil testing laboratory in the appropriate box. Many university extension services have their own boxes for mailing. Contact them in advance of collecting the soil sample to make sure you have the right type of mailer and information form. Enclose any fee the lab charges for testing. Fees are usually less than $10.
