When you know that your lawn needs an application of fertilizer, herbicide, insecticide or fungicide, the question becomes how much to buy and put down. For these products, success stems from applying the right amount, not too much or too little. The label on those products always tells the consumer how many square feet of lawn can be treated, but how do you figure that out?
You could always do it the old-fashioned way with measuring tape and a calculator, estimating the angles and the areas of those curvy, irregular flower beds. This method takes a bit of time and you will still wonder about the accuracy of your final numbers.
Here’s an easier, and more accurate way to do it!
Sod Solutions, Inc. offers an online tool that is easy to use and very accurate. Enter your address and GPS locates the aerial view of your property. Create an overlay by plotting points and the square footage is automatically calculated. The instructions under ‘How to Use the Calculator’ are very clear and makes this tool so easy and convenient to use.

Gardening Solutions: Lawns

Weeds are growing everywhere, especially in manicured lawns and landscapes despite the best efforts of owners who have spared no expense to remove the offending flora. Herbicides to control the weeds seem to be less effective as August progresses.
The reality, at least about the herbicides, is different from perceived appearances. Herbicides can be a wonderful tool for the homeowner, if applied properly.
[important]The first point to remember about herbicides is to always, Always, ALWAYS apply them as instructed by the label directions. The oft quoted mantra of “the label is the law” is accurate.[/important]
Herbicides and their labeling are periodically reviewed and assessed to confirm effectiveness against target weeds without damaging the environment. Not following the label directions can have many negative implications for both the environment and the applicator.
Herbicides are either selective or non-selective when killing plants. Non-selective herbicides kill or damage every plant, but selective herbicides target a narrower range of plants.

Never apply herbicides when there is a breeze or wind. Herbicide drift can injure or destroy plants that are not the intended target.
High temperatures can contribute to the drift problem by volatizing some of the herbicide spray. Even the lightest air movement will cause drift off the target weeds when this condition exists. Herbicide drift can also be deposited in ponds and streams, harming the aquatic creatures that live there. Some herbicides are toxic to fish, insects and other animals that can be killed by tiny amounts of the active chemical. Additionally, the off target herbicides can kill aquatic plants. When the dead plants decay, they deplete the water of oxygen, again threatening or ending the life of the water’s residents.
Rain or dew resulting from high humidity can negate a herbicide’s application. If a leaf is wet, most or all the herbicide will run off on to the soil where it can leach into the water table.
Unless stated on the label, herbicides work only when the plant is actively growing. A hot, dry week or two can put a plant in drought mode, suspending growth and the herbicide’s effectiveness.
Many weeds have already produced seeds for next spring. Herbicides applied now will not affect the germination of that seed months from now.
The most effective strategy is to mow weeds before they set seed or to collect and destroy those which have already produced seed. Even with 100 percent success at eliminating this year’s weed seed crop, there will be weeds next year.
Some weed seed remain in the soil, sometimes for decades, only to germinate when conditions are perfect for their sprouting. Sickle pod and crotalaria are local examples of long term seed vigor.
Other seed can blow in or be dropped by wild or domestic animals passing through the property. A pre-emergent herbicide which stops germination can help control these latent invaders.

The muscadine grape is a popular fruit that grows very well here in North Florida. It has smaller leaves than bunch grapes and fruit are harvested singly, rather than in bunches. Theses grapes can be enjoyed fresh and also be used for home wine-making. One of the nice things about growing muscadine grapes in Florida is that they’re rarely bothered by insects or diseases. They can easily be grown in your backyard garden.

Grapes will grow well in a variety of soils here in North Florida. Upland soils with clay underlying at about three feet are ideal. You should avoid poorly drained soils. If the grapes are grown on soil with very good drainage, they should be set in the ground deeper than they were grown in the nursery on land with a high water table. Grapes should be planted on raised beds at the same depth they were at in the nursery.
During the first year, grapes should be fertilized with a quarter pound of 8-8-8 or 10-10-10 fertilizer, applied in bands about a foot away from the plant, soon after growth begins. Repeat applications in April, July and September. Fertilizer rates increase each year, but they should never exceed six pounds per vine per year.
Weeds can sometimes be a problem with muscadine grapes. To get rid of weeds, you can use a good herbicide, or you can cultivate around the plants. The muscadine grape has a very shallow root system, however, so be careful when you’re weeding around the plants. Mulches can be helpful in controlling weeds, but be sure to leave a circle of at least six inches around each vine uncovered.
Grapes need a generous supply of water to survive here in North Florida. In fact, more first-year grapes die from a lack of water than from any other cause. Make sure the plant receives about an inch of water weekly. Muscadine grapes are rarely bothered by insects or diseases. However, a spray program is advised to protect plants from possible damage by black rot or bitter rot. Spraying should begin when the vines are in bloom, and continue a regular two week intervals until about a week before the harvest. For specific information on the proper spray to use, you should contact your local County Agent.
Muscadine grapes mature in August and early September. If you don’t plan to use them immediately, they should be picked from the vine when ripe and stored at 40 degrees Fahrenheit.

As our world and our lives become more centered on technology it seems that all the information we need is just a touch screen away. After all, you are most likely reading this article from a laptop, smart phone, or tablet. While convenient and portable, there are some places you might not wish to take your electronics and one of those places is in the garden. You may say, “Well Taylor, that’s what they make waterproof, shatterproof, dirt proof, etc. cases for!” and I would say that you’re right. However, technology has many limiting factors such as battery life and screen glare. Now believe me, I am by no means disparaging technology! I come from a generation that considers Wi-Fi as necessary as water and an outlet comparable to oxygen. But there is something to be said for having a book in hand when out in the garden. For one thing your neighbors won’t worry about you as they see you march around the garden with your phone in the air doing the “No Signal Dance”. Also, a book is great to have in order for you to jot down any notes or reflections. I would like to list for you a few books that I often reference when I receive calls from homeowners. These books will cover various topics and all of them can be found on the UF/IFAS Bookstore website, the links for each can be found below. If you have any questions contact your local Extension Office and, as always, feel free to contact me and I can give you a rundown on my collection of favorite reference books!

Most likely, we all have them-garden pots. These typically are made of plastic, clay or wood. Garden pots should be sanitized if they were previously used or if they exhibit signs of mold or fungal growth. Whether they are used as garden boxes, planters, or hanging baskets, the surfaces of garden pots can harbor disease organisms, along with unsightly stains and mineral salts deposits. Salts from hard water and fertilizers can leach though clay pots leaving a white film on the pot’s outer surface. Salts accumulation can become flaky and encrusted around the rim and drainage holes of plastic and clay containers.

To clean clay or plastic containers, use a brush or fine steel wool to remove dirt and debris and wash with a liquid soap detergent. If stains persist, consider using a 50:50 solution of water and vinegar. To sterilize clay or plastic pots, soak them in a mild solution of bleach, 1:10 bleach to water, for about 30 minutes. Then, immerse them in clean water and allow them to dry completely. Containers made of wood are different. If the timber that they are made of is not treated properly, they tend to rot and can harbor disease spores or bacteria. It is best to replace these as they show signs of wear or deterioration. Sanitizing your garden pots will help you avoid unwanted disease problems and unsightly garden container pots.

Native plants can more readily be found in local nurseries to enhance landscape plantings. Not all natives are suited to every habit so it is still important to match the plant’s requirements with a suitable area in the landscape.
One low maintenance native that is more suited to a specific area is the landscape is the Gamma or Fakahatchee grass (Tripsacum dactyloides and T. floridana). This clumping perennial grass grows best in moist or even boggy soils. It has attractive green foliage and upright flower stems that appear in mid summer. Although the flowers are not very significant, they do have a red color when viewed up close.
The Eastern gamma grass can grow five feet in height so many gardeners prefer the dwarf version that reaches about 2-3 feet in height. Plant in areas of full sun or partial shade as a specimen plant or use in a mass of three or five.
In areas that receive colder temperatures, gamma grass can add fall interest to the garden. Leaves will change to a shade of red with first frost and plants can die back to the ground during freezing winters. New growth returns in the spring. Basic maintenance includes pruning back in the spring.
