What fertilizer should I use on my lawn in summer?
Summer fertilizers should be low in nitrogen to avoid stressing the grass. Recommended Fertilizer: Use 10-0-20 Emerald every 6-7 weeks for sustained growth and stress tolerance. You can apply a high-nitrogen fertilizer to cool-season grass in early fall. A formula of 20-8-8 or 24-0-12 are two good options. Always follow the manufacturer’s recommended rate of application.A good NPK ratio is 3-0-1 or close to it. Warm-season grasses should not be fertilized with nitrogen after mid-September since it can delay dormancy. For mid- to late-fall applications, use a high-potassium fertilizer with fast-release nitrogen for cool-season grasses.Late Fall Fertilizer Timing (October – November) This last application of fall lawn fertilizer before the winter can make all the difference in the health of your lawn next spring. Taking the time to fertilize in the fall will strengthen your lawn’s roots, giving them a strong base to thrive on next spring.Grass can only absorb fertilizer when it is actively growing. Turfgrass plants stop growing – become dormant – when the soil temperature is below 55°F or in the heat of the summer. Cooler soil temperatures also slow the bacterial action that makes some fertilizer nutrients available to the plants.Warm-season grasses should be fertilized in late spring, during summer, and in early fall for growth, summer stress tolerance, and winter preparation,” says Smith. Make spring applications about two weeks after green-up to nourish plants as they break winter dormancy.
What fertilizer numbers to use in summer?
Summer Fertilizer Numbers for Your Lawn For summer, the ideal fertilizer ratios include the following: 10-0-4. Proper summer lawn care hinges on using slow-release fertilizers, which nourish the grass steadily to cope with heat and drought. The ideal nutrient mix for summer fertilizers, such as 20-0-10, emphasizes high nitrogen and moderate potassium levels to support strong growth and water retention.A good NPK ratio is 3-0-1 or close to it. Warm-season grasses should not be fertilized with nitrogen after mid-September since it can delay dormancy. For mid- to late-fall applications, use a high-potassium fertilizer with fast-release nitrogen for cool-season grasses.Leading scientists recommend applying nitrogen fertilizers in the spring and fall for cool season grasses like Kentucky Bluegrass, Fescue and Ryegrass, and throughout the summer for warm season grasses like St. Augustine and Bermuda, since this is when the grass plant is actively growing.Autumn lawn feed gives your grass fertiliser to help it grow, but also includes phosphates and potash to protect your lawn against frozen soil and surface frost. In contrast, Spring and Summer lawn feeds are high in nitrogen. This encourages more delicate top growth, which can be damaged quite easily in winter.November fertilization is one of the most important yearly applications to a bluegrass or tall fescue lawn. An application of a high, quick release nitrogen fertilizer will pay big dividends next spring. Examples of fertilizers to use at this time of year are 27-3-3 or 30-0-3.
What fertilizer to use in September?
The best fall fertilizers are high in potassium, provide steady nitrogen without pushing top growth, and often include soil-health boosters like humic acid or carbon. Top recommendations: Stress 12-0-24 — high potassium + micronutrients for stress resistance. High-Nitrogen Fertilizers: Perfect for warm-season grasses like Bermuda, Zoysia, and St. Augustine that thrive during summer. Use options like our 20-0-10 Almighty for optimal growth and greening.Use slow-release fertilizers to prevent lawn burn and maintain steady nutrients. Choose fertilizers with potassium and phosphorus to strengthen roots and fight off drought stress. Feed warm-season turfgrass like Bermuda now, but hold back on cool-season grasses until early fall.For example, a high nitrogen fertiliser is best for spring growth in existing grass as has a higher nitrogen content. Similarly, you can use phosphorus fertilisers and potassium fertilisers to cater to deficiencies. There are quick-start fertilisers available on the market as well.Use slow-release fertilizers to prevent lawn burn and maintain steady nutrients. Choose fertilizers with potassium and phosphorus to strengthen roots and fight off drought stress. Feed warm-season turfgrass like Bermuda now, but hold back on cool-season grasses until early fall.
Is 20-10-10 fertilizer good for lawns?
Lawns: The high nitrogen content in 20-10-10 fertilizer makes it ideal for promoting lush, green grass. Timing: Apply early spring lawn fertilizer once between February and April, when your grass is starting to green up and beginning to actively grow (around the time your lawn first needs to be mowed).Ideally, you should apply a fertilizer treatment to a dry lawn when there is no rain forecasted for the next couple of days. Fertilizing a wet lawn or applying a treatment before rain can lead to: Uneven distribution: Fertilizer applied to a wet lawn may clump together and not spread evenly.The ideal scenario is to apply fertilizer to a dry lawn, especially when no rain is anticipated in the coming days. This approach guarantees the best results for your turf.Early Fall Fertilizer Timing (September – October) During fall, best practices say that September is the best time to fertilize your lawn. So that means you should be taking steps to get your lawn ready for fall and winter right about now.
What fertilizer should I use at the end of summer?
For late summer applications, slow-release fertilizers are the best option. Unlike regular fast-acting fertilizers, which can burn turf and result in rapid but short-lived growth, slow-release options provide a steady supply of nutrients over time. If you have a warm-season lawn, this means you should fertilize your lawn in mid to late spring, then again in summer, and finally in early fall. Depending on where you live, you might be able to start fertilizing as early as April and lay down your last application of fertilizer as late as October.For warm-season grasses like Bermuda or Zoysia, summer is peak growth time, making early-season fertilization — mid-May to early June — ideal. Fertilizing in July and August can also be beneficial. Slow-release fertilization can be an excellent choice of fertilizer in summer months as well, when conditions are right.The answer to that question is a resounding Yes! Not only does applying lawn fertilizer in fall contribute to both the health and good looks of your lawn, but fall is also the ideal time to give your lawn the nutrients it needs for a better lawn now and next spring.Can you fertilise the lawn in August? Yes, you can fertilise your lawn in August. It’s best to stick with a summer feed at this time of year, moving to an autumn lawn fertiliser from September onwards. This month, continue your lawn feed schedule by applying fertiliser every 6–8 weeks.
