The yellowing of grass can be a sign that there is a lack of nitrogen. This problem is called chlorosis and is a result of the grass plant being unable find any usable nitrogen in the soil, so it cannot build new chlorophyll cells (the green part of the plant) so the old cells die and are not replaced 🙈 The leaves then turn yellow, wither and die 🙈 As it cannot produce food anymore, this is a serious problem. It enters shock to move key nutrients back into its core. This is basically hibernation. The plant may die from starvation if it doesn’t improve.
When a lawn has been properly maintained, the amount of nitrogen fertilization required can be reduced by one-third by bringing in grass clippings. Reduce thatch accumulation by cutting only one-third of the grass’s surface per year and maintaining the appropriate height for each type of grass. The recommended heights of cool-season grasses that are hardy in USDA zones 2-7, such as Kentucky bluegrass and some red fescues like Festuca ssp.The recommended height is between 1 1/2 and 2 1/2 inches. Maintain zoysiagrass (Zoysia spp.This grass is suitable for USDA zones 6-9, and can be grown at 1/2-inch to one inch. Bermudagrass (Cynodon species) is another warm-season creeping lawn.The best mower height for bermudagrass (Cynodon spp.), which grows in hot summers in USDA zones 7-10, is 1 to 2 inches.
You can also find additional material here lawnista.com These are mostly plant-based Nitrogen sources, such as animal and plant manure. These Nitrogen Sources take longer to reach the plants than inorganic sources but they are more eco-friendly and affordable. Although they take longer to work, the residual effects can last for years without negatively impacting on the environment. Use an organic fertilizer when it is warm. The reason is that soil organisms, which can be slow or dormant in cold seasons, will break down organic matter to give the soil a mixture of Nitrogen and organic nutrients.

Neil Feliciano thelawnstore.co.uk We can get more information from you. The majority of lawns can grow well without the need to apply a fertilizer in the UK. If you are looking to enhance the appearance and health of your lawn’s grass, fertilisers can help. In order to keep your grass healthy and strong, fertiliser is a good choice. Lawn fertilizer can not only improve the look of your lawn, but also helps your turf recover from the wear and tear of harsh weather and other factors. It is important to keep your turf fertilized with the right nutrients. A well-balanced nutrient programme can help prevent your grass from getting weaker, more patchy or thin. Poorly maintained lawns are more susceptible to diseases.
