Too Early to Fertilize Warm Season Grasses

The last three years temperatures have been strange and erratic. As of this writing, we have had a very mild winter. Without a crystal ball it is hard to predict if we will get colder and freezing weather.

No matter what it does with weather, it is still too early to apply fertilizers to our warm season grasses. It is also too early to put out weed and feed applications now.

So when it is the proper time to fertilize our warm season grasses.

The proper time to fertilize our warm season grasses is around the first or second week of April when our soil temperatures have warmed up. We also recommend mowing your lawn two to three times prior to fertilizing.

We have an excellent publication on Louisiana Lawns, titled “Louisiana Lawns Best Management Practices” publication number 2940. It can also be found on our website.

Citrus Tree Fertilization

All indications are that we had a very good citrus crop this past year. At this time, the majority of the fruit should be harvested off of the trees. If you leave it on too long with the weather we have had the tree is expending a lot of energy to maintain the fruit on it.

Now is the time to be fertilizing our citrus trees. The following information will help you with the amounts to use.

Citrus trees around the home require annual fertilizer applications to maintain good growth and high yield of quality fruit.

Use these Guides Amount of Fertilizer for 8-8-8 or 13-13-13 per tree:

Tree Age:
Amount of Fertilizer:
8-8-8 or 13-13-13
First Year 1-1 1/2 pounds
Second Year 2-3 pounds
Third Year 3-4 1/2 pounds
Fourth Year 4-6 pounds
Fifth Year 5-7 pounds
Sixth Year 6-9 pounds

Increase the rate of fertilizer 1-1 ½ pounds per year as the tree gets older.

Twelve years and older, maximum rate 12-15 pounds of 8-8-8 or 13-13-13.

We also have an excellent publication titled Louisiana Home Citrus Production, publication #1234 can be seen online.

Time to take soil samples for vegetable production and warm season food plots. Samples are $10.00 per sample and they are boxed up and the postage is paid by the individual. The results are sent back between 7 to 10 days and you can call my office to help you with the interpretation of the results.
