The regular cutting and watering of a lawn gradually impoverishes the soil. The plant in process of growth selects useful substances from the soil. Gradually, the soil is exhausted. When watering, nutrients get deep into soils and become inaccessible to roots of plants. Therefore, lawns are periodically necessary for fertilization.
There is a question: how andwhen to fertilize a lawn? Bringing in mineral and organic fertilizers for a lawndepends on the structure of soils, climatic conditions, and the type of grass. There arewarm-season grassesandcool-season grasses.
Accordingly, each type of grass has a resting period and growth period. It influences the schedule of additional lawn grass. For different grasses, either autumn, spring, or summer fertilizations are done.
What does it give to a lawn?
If adding organicfertilizersbefore a cold season, the plant will be ready for the winter and can successfully live through it. Introducing enriched organicfertilizersin the autumn, will improve the structure of the plant.
Before intensive growth, lawns need to be fertilized so that the grass will have mineral substances for growth. There is a popular opinion amongst gardeners that organic fertilizeris better used when the grass goes into a dormant period.
Cool-season grasses - when to fertilize a lawn.
It is recommend that you fertilize a lawn using complex mineralfertilizerswhen the grass starts to grow after a resting condition. It is better to bring nitricfertilizersinto the soilduring the period before the intensive growth of grass than during it.
Mineral nitricfertilizers for lawnstimulate grass growth. They are especially necessary after the winter, when the grass is exhausted. The addition of mineralfertilizersallows grass to restore their elevated part and develop roots. However, mineral fertilizers do not improve soil structure, and they only feed the plants. Therefore, it is important to introduce mineralfertilizers for lawnin controlled quantities so that you do not break the soil’s micro flora.
Nitric fertilizers forcool-season grassesbring and early spring after a winter’s rest and an early autumn when heat is not available.. During the spring and autumn time,cool-season grassesgrow best. During this time, additional fertilizer is added to the grass.
Warm-season grasses when to fertilize lawn
Warm-season grassesbegin their growth in the spring and continue into the frosts.Warm-season grassescan successfully survive the winter and a cycle repeats in the spring. In this case, nitric fertilizers are added it in the spring. In the summer, additional fertilizing is required if the leaves of the plants become dim and the grass grows poorly.
What kind of fertilizers for lawn can be used?
There are many types of fertilizers for lawns, which can influence a plant. There are those that have organic substances that suppress the growth of some weeds, moss or plant pests.
Mineralfertilizers for a lawncan be fast or slow. What does that mean?Fertilizersof slow action take at least 2-6 months to affect a lawn gradually providing useful substances to grass. These are usually granulated mineral fertilizers. They are very convenient, as they do not demand to be frequently entered into the soil. Under the influence of water and natural moisture, they gradually seep into the soil.
Fast mineralfertilizersareliquid fertilizers. They are concentrated.Liquid fertilizersare necessary to use with watering. For this, the watering hose is fastened to the container with the fertilizer. Thus, watering is done withfertilizers.Liquid fertilizersare the most available to plants since they are immediately transported to the roots of the grass.Liquid fertilizersare an expensive option, especially for big lawns.
Syntheticfertilizers,or chemicalfertilizersgive a fast effect, they quickly get into the soil. It can be potash, phosphoric fertilizers, and other combinations. Phosphorus is slowly absorbed by grass roots, and therefore the introduction of phosphoricfertilizersis done once every few years. Potassium quickly falls to the bottom layers of the ground. Therefore, potash fertilizers e added annually. In clay soils, potashfertilizeris slower to wash away from the soil than on loamy or sandy soils. Accordingly, it is necessary to fertilize a lawn depending on soil structure. A lack of syntheticfertilizerscan cause an excess offertilizerseasily. This is dangerous as it can burn grass.
Organicfertilizersfunction slowly. They improve the soil condition; many in compost are available for a plant. Except for the trace elements in compost, there is a large number of various bacteria and fungi, which entering the soil and actively influence the restoration of natural micro flora of the soil.
There are various combinations offertilizersfor your lawn which can be selected depending on the type of grass and the climate.
General rules for a lawn before introducing fertilizers:
Before fertilizers are introduced, cut the lawn. This allows for the best penetration of the fertilizers.
Clear the mowed grass from the lawn so thatfertilizerswill get to the soil easier.
When usingfertilizers, use the instructions listed as a guide.
Do not introduce afertilizerin to dry soil during droughts.
