A $9 soil sample can tell you the type and amount of nutrients that should be added for your lawn, garden and other plants. You will need two cups of soil, free of debris, made of up ten random samples taken across the area. Sample to the depth of cultivation for a garden or four inches for a lawn. Pick up a soil sample bag and form, or bring the two cups of soil in a plastic baggie or other clean container to the County Extension Office. Testing may take up to 10-14 days. We will mail or email you the results.
The basic water test is $20.00 and will tell you the pH and hardness of your water, and the metal content for 17 key metals. Bring your first draw in a clean, clear lidded container. Expanded tests are available if you are putting in a water treatment system or need more information. Call (912) 554-7577 for details.

Centipede lawn: second and final fertilizer application due now!
We love centipede lawns because they look good and cost less to maintain than other turfs. Centipede lawn decline is caused by improper lawn maintenance: too much nitrogen fertilizer, cutting too high and watering too much. If you applied half the fertilizer for the year in May, now in early July is the time to apply the other half. Half a pound on nitrogen in May and another half-pound of nitrogen per thousand square feet in early July tends to give the best results. Mow at 1-2 inches height with 1.5 inches being ideal. Irrigate with half an inch of water when the lawn starts to wilt. Let it start to wilt before irrigating again, but don’t let it turn brown and crunchy under foot.
Fertilizer recommendations by grass type
IMPORTANT: Recommendation is TOTAL PER YEAR. If you are putting down fertilizer over 2 or 4 months, use 1/2 or 1/4 of the amount.
- 2-5 lbs/1000 sq ft/year
- Best= May, June, July, August
- 1-2 lbs/1000 sq ft/year
- Best= May, July
- Possible= June, August
- 2-5 lbs/1000 Sq ft/year
- Best= May, June, July, August
- 2-3 lbs/1000 sq ft/year
- Best=May, June, July, August
Prune your Azaleas before July 4
Azaleas set their buds in July for the next spring, so the best time to trim them up is within 3 weeks after the flowers drop. In our area, prune before July 4 or you risk cutting off the bud sets and reducing your flowers for next spring. Azaleas aren't meant to be shaped shrubs. If you use hedge clippers, your flowers will be limited to the outside of your plant. Trim with hand trimmers to thin out branches and dead wood and ensure that your plant will have the maximum blooms.
In the vegetable garden
Pull up grass to keep it from going to seed. Clean off harvested rows immediately to prevent insect and disease buildup. Plant the following vegetables no later than July 20 to allow time to mature before frost: tomatoes, okra, corn, pole beans and lima beans. You can also plant cucumbers, squash and snap beans.
Killing your trees with mulch
The Extension office has had several calls about sick trees. A common problem is mulch that covers the bark at the base of the tree. The bark at the base of the tree is aerial bark which needs wind and sun to thrive. If you cover this aerial bark with mulch, fungus will thrive, degrading and decaying the bark. Once the decay reaches the tree's cambium, the tree will die. So take your hands and pull the mulch away from the base of the tree, allowing about 6 inches. Don't use a rake or hoe, or you will risk damaging the aerial roots.
Crape Murder or Crape Myrtle?
What's wrong with this picture?
This kind of pruning causes really strong growth right at the top. But in the long run that growth will be too dense for light and air to reach the inner branches, making the tree susceptible to disease and insects. Also, the branches will be weak. If you don't prune them, Crape Myrtle trees will set blooms all over. Or if needed, just thin out excess branches as you would any other tree.
Southern Living magazine has taken up the cause of the Crape Myrtle murders. If you see a particularly bad example, submit to the annual contest for the worst Crape Murder.
