How To Choose The Best Fertilizers For Grass In Fall?
Fall lawn fertilization treated adequately will keep your grass healthy during winter and have a quick start in the spring.
Instead of pushing grass growth on your lawn, fall fertilization plays a different role that is to increase sugar storage in the grass crowns. Hearty sugar-filled tops are disease-resistant during the winter as well as able to green-up fast in the spring.
Regarding the stimulation of crown building, lawn owners need to take into consideration two things: the proper fertilizer and the right timing.
Types Of Fertilizer To Apply
- As a basic knowledge of fertilizer, NPK ratio, which indicates three main ingredients, stands for Nitrogen - Phosphorus - Potassium.
- Nitrogen is an ingredient that enables grass blades to increase sunlight-harvesting chlorophyll. More chlorophyll blades have more sugar stores in the crowns. So, the ideal fertilizer should contain a high level of nitrogen to build up a healthy lawn.
- Phosphorus is an essential factor in having a beautiful and lush lawn. However, most experts recommend that we should avoid using high-phosphorus fertilizer to prevent it from running off into the water supply. It can cause water-pollution and harm the environment.
- Potassium is functioned as a stomata located within the grass cell solution. It keeps the grass from wilting and allows water to deliver through cells. So that potassium is mobile within the plant, deficiency symptoms appear on dry or yellow grass as necrotic edges.
- In brief, a high level of nitrogen and potassium with low amounts of phosphate fertilizer is an ideal option for fall application.
Time To Apply
- Following the different soil conditions and types of grass, a fall fertilizer is supposed to apply from September to November.
- For early fall or early September, you should apply fertilizer to revitalize the green blade color after the heat stress of summer. At this time, overseeding a lawn is better because of the high nitrogen source. It also needs a regular watering schedule.
- At mid-fall, about late October, it’s time to apply lawn food for well-balanced nutrition to build a robust root system and improve soil quality.
- For late fall or late November, it’s high time as suggestions from experts for fall fertilization because the roots have many nutrients delivered at the right time. It can help your lawn to fight against the freezing weather of winter.
