You could certainly argue that the azalea bloom is the symbol of the southeast during spring time. This time of year, yards across the panhandle explode with vibrant colors of this unmistakable flower bloom. Even though Florida’s azalea plants put on a spectacular flowery show, most of us pay very little attention to their management at this time of year. However, the kind of care azaleas receive in late spring and summer can have an effect on the bloom production for next season. There are some management measures that can be done during this time to ensure that you have a bountiful azalea bloom next spring.
Chlorosis, a condition that causes leaves to produce insufficient chlorophyll, is the most common problem with azaleas this time of year. Fortunately, this is easy to recognize and correct. Chlorosis shows up as yellowing in between the veins of leaves, the veins stay dark green. It’s caused by lack of available iron in the soil.
To correct chlorosis, add aluminum sulfate to the soil. The addition of ¼ to a ½ pound per square yard of soil surface should suffice. Broadcast the aluminum sulfate over the soil surface and add a layer of mulch. It’s important to remember that you should not apply aluminum sulfate more than once a year. More applications will cause detrimental effects to the plant. Other chemicals that are useful in correcting iron chlorosis in azaleas are ordinary agricultural sulfur, ferrous sulfate and chelated iron compounds. Each of these chemicals have different application directions, so be sure to read the labels for direction of use.
Proper watering is also imperative. Generally, established plants should receive ¾ – 1 inch of water every 10 days to 2 weeks during dry periods to wet the soil to a depth of 10-12 inches. When the weather is hot and dry, azaleas need soil saturation in the root zone once a week. Azaleas have shallow feeder roots that dry out very quickly if the soil is dry. Remember, soil with a sufficient amount of organic matter holds moisture better than sandy soils, and will require less watering. Also, a mulch layer helps to reduce evaporation and keep the soil cool and moist.
Pruning your plants should be done in late spring. If you prune later in the year, there’s a good chance you may reduce or eliminate flowers for next year. Usually it’s best to prune right after flowering.
As for fertilizer applications, frequent and light applications are necessary in Florida’s sandy soils. Acid-forming fertilizers like 12-4-8, 15-0-15 or ammonium sulfate should be applied in all four seasons. Apply approximately ¼ pound to a mature plant, or ¾ to 1 ½ pounds per 100 square feet.
Following these recommendations will help secure your rich bloom season for next year.

Merry, I never use salt when cooking rice and prefer to add a little bit of butter instead of olive oil because I like the taste butter imparts. However, neither olive oil nor butter are necessary for cooking rice. Another great way to cook rice is by using chicken broth instead of water. The finished rice has a delicious chicken flavor that can boost the overall richness of the final product. As for short- and medium-grain vs. long-grain rice, they are not created equal. You will generally not get the same results from short- or medium-grain rice as you will from long-grain rice, especially if a recipe specifically calls for long-grain rice. Long-grain rice, when cooked, is dry and loose, whereas short- and medium-grain rice is sticky and clumps together. For fried rice, long-grain is best. Short-grain rice is great for rice pudding and sushi, whereas medium-grain rice is best used for dishes such as risotto. Samantha Kennedy, M.S.

This is quite helpful. Being in self isolation quite a distance from home, I inevitably needed a culinary companion. This site has been the guide I so much needed. Cooking rice is the combination of art and science. I sometimes see chefs sprinkling salt and olive oil when preparing rice, what’s your take on this? And would you get the same results if you used short or medium grain variety?

Thanks for writing about organic gardening. More and more gardeners are turning to it, but there are still more to convince. I want to correct the notion that organic gardens require lots of work, particularly weeding. I practice a form of organic gardening that uses heavy mulches to suppress weeds. Mulches also protect the soil from burning up under our hot subtropical sun, promote beneficial microbial activity, and add organic matter to the soil when they eventually break down. This results in an average of about 5 minutes a month spent weeding a 1500 square foot garden. I'm guessing it takes quite a bit longer than that to spray poisonous herbicides over the same area. I've been using this method for over 17 years with wonderful results and would never go back to bare earth gardening.

Hi Donna. For better results, zoysiagrass require frequent fertilization. Periodic soil testing should be conducted every 2 to 3 years as the basis for applications of lime and fertilization. Your local county extension office can help with your soil testing needs. Soil test results will help determine management measures, such as to maintain the proper soil pH between the desired range of 6.0 to 6.5 and keep the nitrogen, phosphorous, and potassium levels at recommended levels. For minimum maintenance, it is recommended to apply between 2 to 3 pounds of actual nitrogen per 1,000 square feet of zoysiagrass lawn per year in north Florida. To accomplish this, apply a complete fertilizer such as 16-4-8, 13-13-13, or10-10-10 at least three times a year in April, June, and August.

So what months should zoysia be fertilized and with what type fertilizer? I put it my small backyard a couple years ago.

Two green thumbs up! Old-timers here in Pensacola say you can pinch back azaleas 'til the Fourth of July and still get a good bloom; this works well for me. (They also say you should plant your potatoes and fertilize your rose bushes on Valentine's Day and that you can pinch back your poinsettias until Labor Day. This also works well for me as far as the rose bushes and poinsettias go. I haven't tried potatoes yet, but maybe I'll try planting some on Valentine's Day, 2017.)

We know all about plants, but not about the law. You may want to consult a lawyer or state agency that deals with these issues. Good luck!

Can the HOA's stop you from having a small garden? There is nothing in the Master Documents that address this issue in particular.

Ants are also amazing. They aerate the soil, help with decomposition and waste removal, plant seeds, and are food for many birds and other animals. I'm all for getting rid of the invasive fire ants but I'd discourage people from killing the other ants in their yards.

Thanks for the timely article. One of the things I dislike about vacations is that I have to leave my plants unattended. I think the points you raised were just perfect. As to houseplants, I would only add that there are self-watering systems one can use as well. They’re better than nothing if you’re going to be away for an extended period of time.

Hello Roy, My wife and I have been raising bees for about a year. As novice beekeepers we are seeking natural methods instead of the chemical practices you mentioned in the article to ensure a healthy hive in the spring. We are open to any suggestions you may have. Thank you in advance for your help. Brett

Great article but you did not mention soil Ph. I have quite a few daylilies but their foliage is slightly yellow. I have used a good fertilizer but wonder if the Ph is not right. Thanks for any information you can provide. Carolyn

William, thanks for your question. This is a common issue, since many folks apply fertilizer to centipede grass late in the year to green it up. Doing this does little or nothing for greening up the lawn and can actually harm the grass by encouraging growth when it is entering its dormant period. This can also encourage late season root rots. As a general rule, I would recommend the last application of fertilizer to Centipede and St. Augustine in mid September. Absolutely no ferteilzer should be applied after September 31st. For more information, take a look at this publication on Centipedegrass from UF IFAS Extension. Hope this helps, Matt

Mr. Carter- i work with the Florida Fish and Wildlife Commission and need to know when the best time to apply fall fertilizer to St. Augustine and Centipede grass; I learned in an earlier artical about the right time to apply lawn fertilizer for the spring is after the soil has warmed up...but didn't see anything mentioned about fall/winter applications. Your response is greatly appreciated. Thank you, William Doc Dockery
