Generally, the best time of year to apply weed and feed to St. Augustine grass is during the spring and fall. During the spring, weed and feed should be applied after the grass has greened up from winter dormancy and with the start of active growth.
During the fall, weed and feed should be applied in late September or early October before the grass enters dormancy and during the period of active growth. Depending on the region, additional applications may be necessary to maintain an optimal level of weed suppression and fertilization throughout the growing season.
To ensure proper timing, it is important to consult your local Cooperative Extension for weed and feed recommendations for your particular region and climate. Additionally, it is beneficial to carefully read and follow the instructions on the weed and feed product label.
What month do you fertilize St. Augustine?
If you are looking to fertilize your St. Augustine grass, the best time to do so is typically during the hottest months of summer, from late May to midsummer. During this time frame, St. Augustine grass has its most active growth, meaning that it’s also the time when it will benefit most from fertilizers.
That said, you can fertilize St. Augustine any time of year, though you’ll want to do so sparingly during cooler months. Keep in mind that late fall applications of fertilizer can encourage tender new growth, which is more sensitive to cold temperatures and can get damaged in a freeze.
Once you’ve decided to fertilize, you can use a slow-release granular formulation like Dr. Earth’s Organic & Natural Lawn Fertilizer to give your grass a nutritional boost. This fertilizer helps protect soil health, build strong roots and fight disease.
However, you should always read the product label guidelines and directions carefully before applying fertilizer to your St. Augustine grass.
What happens if you put Scotts weed and feed on St. Augustine?
If you put Scotts weed and feed on St. Augustine, you may get varying results depending on the type of fertilizer you are using. If you use a fertilizer with a high nitrogen content such as a 20-0-0, you may find that it can cause excessive blade growth, leading to a shallow root system and weed invasion.
If you use a fertilizer with a lower nitrogen content, such as a 15-0-15 or 16-4-8, you may find that it will promote healthy grass growth, while providing some weed control if applied at higher rates.
However, it is best to check the fertilizer label to make sure it is suitable for this grass type before applying.
How do you treat weeds in St. Augustine grass?
The best way to treat weeds in St. Augustine grass is to use a pre-emergent herbicide. Pre-emergent herbicides are designed to prevent weed seeds from germinating in the first place, essentially stopping them before they start.
Applying a pre-emergent herbicide before the weeds start to sprout can dramatically reduce the amount of weeding you need to do. It’s important to note that pre-emergent herbicides are only effective if they are applied before weed seeds germinate, so it’s important to time your application correctly.
In addition to pre-emergent herbicides, you can also use post-emergent herbicides to get rid of existing weeds. Post-emergent herbicides kill existing weeds, but they won’t prevent new ones from coming up.
You can use either a selective post-emergent herbicide, which will kill certain types of weeds, or a non-selective post-emergent herbicide, which will kill anything it touches.
Finally, you can help prevent weeds from taking root in St. Augustine grass by regularly mowing your lawn and herbiciding it with a post-emergent herbicide. If you keep your lawn mowed and cleaned up, weeds won’t have a chance to set in and thrive.
Additionally, you can spot-treat particular weeds with an herbicide.
Using these methods, you can effectively treat and prevent weeds in St. Augustine grass. Pre-emergent herbicides stop weed seeds from germinating, while post-emergent herbicides treat existing weeds, and regular mowing and spot treating can help keep weeds away altogether.
Does Scotts Weed and Feed contain atrazine?
No, Scotts Weed and Feed does not contain atrazine. Scotts Weed and Feed is a fertilizer and weed control product designed to help lawns grow strong and healthy. It contains pelletized fertilizer and an herbicide to help control weeds.
The herbicide ingredients are prodiamine and MCPA, which are both selective pre-emergence herbicides. While prodiamine has proven to be effective in controlling crabgrass, dandelion and other broadleaf weeds, it does not contain the ingredient atrazine, which is commonly found in weed control products.
Does St. Augustine grass like nitrogen?
Yes, St. Augustine grass does like nitrogen. Nitrogen is an essential nutrient for all grasses, and St. Augustine grass is no exception. Nitrogen helps to promote strong and healthy growth, vibrant color, and overall better performance.
Without sufficient nitrogen, the grass may be thin and prone to diseases and pest issues. One way to ensure your St. Augustine grass gets enough nitrogen is to fertilize it. If applied at the right time and in the right amount, fertilizer will provide the nitrogen your grass needs.
Applying fertilizer in the fall and spring are great times to add nitrogen to your St. Augustine grass. As with any fertilizer, always follow the application instructions on the package. It is also important to monitor your grass’s growth and condition and to adjust the amount of fertilizer accordingly.
Applying too much nitrogen can cause the grass to thin, or even burn.

How do I make my St. Augustine grass thicker and greener?
Making your St. Augustine grass thicker and greener is a process. You will need to start by evaluating the current soil health and making any needed improvements by testing and adding the correct fertilizer.
You should also check the pH of the soil and, if necessary, adjust the levels to keep it in the desired range. Additionally, you may need to reseed any bare areas to achieve a fuller turf.
When watering your St. Augustine grass, it is important to water deeply. This will help to encourage deep rooting and growth. Furthermore, avoiding frequent and shallow sprinklings will deter fungus and disease.
When mowing, make sure you’re using the proper height and sharp blades to avoid scalping the grass. By avoiding scalping, you can help the grass retain water and stay vigorous.
Finally, using an appropriate insect control product in the spring and fall can also help to keep your St. Augustine grass looking thick and green. The insect control product will combat any pests that might be feeding on the turf, thereby keeping its health and appearance of the grass in optimal condition.
With all of these steps, your St. Augustine grass will soon become lush, thick and green.
What helps St. Augustine grass grow?
St. Augustine grass needs a range of conditions to grow that includes ample sunlight, moist soil, and nutrient-rich soil. For best growth, the soil should have a pH of 6.0-7.5, with 6.2-6.8 being optimal.
To increase the soil’s fertility, you should incorporate organic material such as compost or manure. Additionally, adding a thin layer of mulch can help to retain moisture and add nutrients to the soil.
Be sure to water the grass regularly and deeply, aiming for 1” of water every week during dry spells. You should also make sure to mow the grass often and at higher heights to promote its growth. Lastly, adding a quality fertilizer at least once or twice a year can help to increase St.
Augustine grass’ health, vigor, and color.
Will St. Augustine grass choke out weeds?
St. Augustine grass (Stenotaphrum secundatum) is quite effective at choking out weeds. It is an aggressive, medium- to coarse-textured turfgrass that spreads through a network of long, underground stems called “stolons.
” These stolons are particularly effective at choking out nearby, competing vegetation such as weeds. The grass has a high wear tolerance, making it suitable to areas that experience heavy foot traffic. St.
Augustine has a deep root system that helps keep the turf from being stressed, as well as keeping other plants from taking root. The grass also works well in shady areas, making it an ideal choice for areas that do not get direct sunlight for long periods of time.
Once it is established, St. Augustine grass is usually very difficult for weeds to penetrate, making for an effective form of weed control.
Is roundup for lawns safe for St. Augustine?
Yes, Roundup for Lawns is generally considered to be safe for St. Augustine grass. Although some formulations of Roundup may affect St. Augustine in the short-term, the more common concentrations used in products for lawns generally don’t cause any long-term damage.
That being said, it is always important to read the label before use and follow the directions for safely and effectively applying the product to your lawn. Also, it is important to take into consideration the surrounding environment before application, as Roundup can easily harm non-target plants and animals if used incorrectly.
Although Roundup is generally safe for St. Augustine, it is important to also use other tools such gardening techniques and cultural practices in order to properly manage weeds and maintain a healthy lawn.
