Fertilizer is a necessary part of maintaining a lush and green lawn. A balanced fertilizer promotes strong root growth while providing essential nutrients–allowing your grass to better tolerate drought, disease, and other stressors. Understanding the different components of fertilizer will help you make an informed decision when selecting a fertilizer for your St. Augustine Grass lawn.
A complete fertilizer contains three main macronutrients: nitrogen (N), phosphorus (P), and potassium (K). Nitrogen is responsible for promoting turfgrass growth through photosynthesis; phosphorus aids in cell development, helps plants resist stressors; potassium aids in water absorption and drought tolerance; together these elements are critical to maintaining healthy grass.
In addition to the macronutrients listed above, micronutrients such as iron, zinc, copper and manganese are also essential for healthier turfgrass. These minor nutrients generally exist in soil in lower concentrations than the major nutrients; however they are vital for optimum metabolic functioning of the grass blade cells.
Finally, some fertilizers contain non-toxic ingredients such as wetting agents or humectants that help them perform better by providing additional moisture or allowing slow release formulas to break down slowly over time instead of drenching your lawn all at once with too much nitrogen.
Definition of fertilizers
Fertilizers are important when it comes to owning a lush, green lawn because they help grass to get the nutrients it needs to thrive. In this guide, we will explain what fertilizers are, how they work, and why you should be using them on your St. Augustine grass.
Fertilizers are substances that help provide the essential nutrients needed for plants to grow healthy and strong. They contain ingredients like nitrogen, phosphorus, potassium (or “NPK”), calcium and magnesium. These ingredients help in the growth process of your lawn’s grass blades as well as nourish the soil so it can act as a nutrient reservoir for future plant growth.
Additionally, most fertilizers also contain minor elements like sulfur, boron and zinc which might be absent from local soils or in insufficient quantities for optimum growth of your lawn’s grasses. Therefore using fertilizer may be necessary to ensure a greener lawn that’s less prone to disease or drought-tolerance problems that could potentially damage your yard’s aesthetic appeal and monetary value.
Nutrient requirements of St. Augustine grass
St. Augustine grass requires additional fertilizer to stay healthy and green. This grass species can benefit from several components including nitrogen, potassium, phosphorus and micronutrients such as iron and zinc.
Nitrogen is an essential element necessary for rapid growth, development of strong stems and higher seed production of St. Augustine grass. Potassium promotes warmer temperatures, stress tolerance, water use efficiency and disease resistance. Phosphorus helps maintain deep root systems while improving the rate of water uptake in the community soil. Micronutrients provide balance to soil fertility and are necessary for accelerated photosynthesis which supports healthy leaves in the St Augustine grass.
Fertilizer should be applied every 12 weeks throughout the growing season with an appropriate application rate as directed on the label; it should be increased or decreased according to soil nutrient test results or changes in weather conditions throughout the year. Excess fertilizer will harm specially adapted sand-based soils by limiting its capacity to absorb water due to plant debris buildup from over-fertilization; it can also leach into surface waters polluting waterways if misapplied during periods of heavy rainfall or snow melting during winter months. Therefore, you should adhere strictly to application rates recommended by your local supplier when using chemical fertilizers on St Augustine grass lawns to minimize chances of redundancy or pollution from leaching into surface waters.
Understanding fertilizer labels
When shopping for fertilizer, it is important to understand the numbers found on the label. It helps because it will tell you how much of each nutrient is in the fertilizer you are purchasing. Fertilizers are labeled with three types of nutrient concentrations. The first number is typically nitrogen, which helps promote dense, green grass. The second number represents phosphorus, which encourages strong root and shoot systems. The third number indicates potassium, which increases disease resistance and strength for summer weather conditions. These numbers are always listed in the same order and describe what percentage by weight of each nutrient is present in an individual batch of fertilizer.
For example, if a bag of fertilizer states that it contains 15-5-10, then 15 percent of it corresponds to nitrogen (N), 5 percent to phosphorus (P), and 10 percent to potassium (K). This means that when using 1lb of this particular fertilizer mix, it will provide: 0.15lbs of nitrogen; 0.05lbs of phosphate; and 0.10lbs of potash per 1lb of product used.
Be sure to check the package label for further information on exact applications rates based on soil type and grass type when fertilizing your lawn with St Augustine Grass!
How to Apply Fertilizer
Fear not! Applying fertilizer is one of the simplest aspects of lawn maintenance. To ensure that you apply fertilizer correctly, start by determining the kind of grass you’re working with; St. Augustine requires specific levels of nitrogen to stay healthy and vigorous. Once you know your grass type, select a fertilizer tailored to it, then take a few moments to craft your application plan.
When applying fertilizer, be sure to opt for smaller applications rather than fewer but larger applications; this not only ensures that your soil won’t be saturated with nutrients, but also makes distribution easier and more even. As for frequency, typically speaking you should apply fertilizer once or twice during the growing period — spring and fall tend to work best — although if your soil tests low on essential minerals or nutrients during any other point in the season it may be beneficial to apply a light dose again then as well.
For optimal results follow instructions included on the back of your chosen brand’s packaging carefully and try not to exceed recommended dosages as fertilizers are designed only for homes with periods of no rainfall lasting up to ten weeks at most. If possible, lock-in moisture before applying fertilizer by lightly soaking your lawn the day before application; this helps promote deeper absorption to get those lovely, lush green results St Augustine is known for!
Tools needed for fertilization
It is important to have the right tools when preparing and applying fertilizer to your St. Augustine grass. You will need a fertilizer spreader or spreader/sprayer combination, a rake, and a broom or leaf blower.
A fertilizer spreader is designed to spread granulated fertilizers evenly over an area of turf. The spreader should be calibrated according to the manufacturer’s instructions and the specific type of fertilizer you are applying.
A rake is used for mixing soil amendments such as gypsum, lime, and sulfur into the soil profile prior to fertilizer application. Finally a broom or leaf blower can be used for removing any excess fertilizer that may have been deposited on hard surfaces like driveways, sidewalks, etc. as well as foliage that didn’t receive any product from the spreader application.
Ensure that all tools are in good working condition prior to use so you can achieve optimum results with your St. Augustine turf fertilization program.
Proper application techniques for St. Augustine grass
Once you’ve chosen the right fertilizer for your St. Augustine grass, the proper application techniques are essential to having a lush, green lawn.
In general, fertilizers should be applied during the grasses’ active growth period. St. Augustine grass is an active grower in spring and summer, so these are the ideal times to fertilize your lawn. It’s also important to make sure that you evenly distribute the fertilizer across your entire lawn using a rotary or broadcast spreader. Before applying, check the soil moisture level – dry soils need more water than wet soils in order for nutrients to be absorbed into the roots of your grass plants. Lastly, be sure not to apply too much fertilizer as this can result in nutrient runoff and pollute local water bodies such as lakes or rivers – follow the manufacturer’s guidelines closely!
While it may seem time-consuming, providing your St. Augustine grass with proper nutrition through regular fertilization will help keep its health and vigor intact throughout different seasons of growth. Be sure to invest in a excellent quality fertilizer that suits both your purpose and pocketbook; with proper application techniques and consistent watering schedules, you can nourish your lawn into a strong and healthy specimen that can withstand both drought conditions and warm weather stressors!
Tips for even application and avoiding lawn burn
When applying fertilizer, it is important to get an even application; you don’t want to give any one area too much or too little fertilizer. It is best to do this either by hand or with a broadcast spreader. Be sure to keep the lawn mowed before applying fertilizer as this will make sure that the fertilizer does not end up sitting on top of tall grass which could cause lawn burn.
Start by making a border approximately 4-6 feet from sidewalks and drives and brush out the edge of your lawn before entering the lawn so that you do not end up applying fertilizer directly onto those areas. Continue working lines in your lawn going both directions until finished.
If using a broadcast spreader, be sure to calibrate it properly first by following the manufacturer’s instructions as this will help ensure even application as well as avoiding any loss of product through wind drift.
Additional Tips for Maintaining a Healthy Lawn
Taking care of your St. Augustine grass requires more than just fertilizer, you need to ensure your lawn gets the right amount of water and receive consistent mowing/trimming. Here are some additional tips for maintaining a healthy and lush lawn:
- Watering consistently: St. Augustine grass needs about 1-inch of water per week. The best practice for watering is to spread it out over two to three waterings per week to promote healthy root systems and discourage weed growth.
- Mowing/Trimming: Mowing is key for any lawn but especially for St. Augustine grass because it discourages the grass’s invasive growth habit as well as providing sun exposure to the blades which encourages photosynthesis and growth of new leaves. Mower blade should always remain sharp in order to avoid potentially damaging your plants with a rough cut.
- Weed Control: Weeds will likely appear in your St Augustine lawn despite all attempts at prevention, usually through planting seeds on wind, wildlife, or human vectors; through shallow root propagation when cut too short; or other biological means that facilitate quick reproduction and growth habits that take advantage of otherwise low quality soil or neglected areas of the yard that don’t receive enough light or attention from maintenance staff. For weeds that have grown too large, consider using a natural herbicide like vinegar or boiling water to remove them from your yard without using potentially hazardous chemicals around plants and beneficial insects living in your yard!
Proper watering techniques
When caring for your St. Augustine grass it is important to understand the proper watering techniques. Watering too often or too much can create a damp, soggy lawn that can lead to disease and pest problems, while not enough water will cause your lawn to wilt and have a yellow-brown color.
To properly water your lawn, you should water deeply one day a week. That means thoroughly watering the lawn until the top 4-6 inches of soil are moist. On weeks with no rainfall you should also increase watering to twice a week, but allowing more time in between sessions so that moisture can deeply penetrate into the soil.
In areas where temperatures reach over 100°F (38°C), it’s recommended to increase watering frequency again and reduce session duration so that there isn’t any wilting or stressed grass blades due to evaporation during extremely hot weather conditions.
Lawn mowing practices
Maintaining your St. Augustine grass starts with proper lawn mowing practices. The grass should be mowed at least once a week, but no more than twice a week. Set the blade height to 1.5-2.5 inches and do not scalp, which is mowing against the grain of the grass or removing more than one-third of the leaf blades per mow. Doing so can seriously weaken the turf, causing it to become thin and producing bare spots in your lawn.
Be sure to water your lawn before you start mowing as it can cause damage if you mow wet grasses – it’s much preferred to wait until after a rainfall or irrigation system has had time to thoroughly wet your turf. Also, when you are done mowing make sure that you leave an extra inch or two of height above the blades so they don’t get baked by the sun while they re-grow during nighttime hours.
Weed and pest control
In addition to fertilizer, proper weed and pest control are also essential for maintaining a lush, green St. Augustine grass lawn. While minimal pesticides or herbicides may be beneficial to help keep weeds and insects away, it is best to consult a professional before applying any such products.
When it comes to weeds in St. Augustine grass, the best treatment is prevention by consistent mowing and fertilizing. If weed invasion does occur, hand removal of the plant material is recommended rather than treating with weed killer as this can damage your lawn turf and cause more extensive damage in the long run.
Regular checking of your yard can help you spot pests early on so that targeted treatments can be applied before more serious infestations occur, and chemical treatments should always be used judiciously to avoid accidental damage to other nearby plants or animals.
At the end of the day, keeping your St. Augustine Grass healthy and looking its best is a matter of understanding what your lawn needs and taking the time to apply it. Once you have learned a few basics on fertilizers, you can help your lawn stay green and healthy all year long!
The application of fertilizer should take place at least four to six times per year, but make sure to check your local climate and soil type before doing so as well as local laws that pertain to fertilizer usage. Additionally, when in doubt, seek professional help from a qualified lawn care specialist or contact your local agricultural extension office.
With proper maintenance and regular application of the mentioned nutrients, your St. Augustine Grass will thrive!
