Lawn care In A Dry Climate – Rejuvenating A Worn Out Grass
Growing a yard is mainly a question of carrying out the regular maintenance right. Sometimes though, additional measures are needed.
Springtime is the season for bringing back to life a yard in a house garden which has seen better days. We all know what a worn out yard looks like; bare spots, heaps of weeds and week yellowish growth. These of course are the symptoms of a lawn. An comprehension of the causes on the flip side, enhances the possibilities of successfully revamping the yard, and ensuring that the same pattern doesn’t repeat itself in the future.
The explanations for why a grass degenerates could be boiled down to two primary components. The first requires upkeep as well as general care. In a dry climate garden as an example, with long, hot summers, correct irrigation practices are critical, as is routine mowing and in the right height. Other jobs for example feeding and dethatching, lead to the success or otherwise of the yard.
If a yard is poor from day 1, then it’s practical to presume the soil wasn’t adequately prepared prior to turfing. Assuming however a grass did grow satisfactorily at one time, but has since decreased, and assuming as well the routine maintenance jobs are in order, then the reason behind its decline can likely be traced to compaction in the topsoil level, resulting from the impact of excessive foot traffic on a comparatively small place. Compaction means the air spaces within the soil have been destroyed, leading to an exchange of gasses, and inadequate water infiltration. (i.e. not enough oxygen available for the roots to breathe)
Oftentimes, topsoil compaction could be alleviated by the actions of a dethatching or scarifying machine, that not only removes the thatch (the build-up of organic matter that decomposes very slowly) but also digs into the soil to a depth of one or two cm, therefore breaking-up the tempered, impervious top layer of the soil. The perfect time for this may be actually the midst of springtime, while the grass recovers faster in the warmer weather. It’s possible to scarify within the summertime, however there’s the danger of destruction to the grass stems from the higher amounts of radiation at that season.
Scarifying is most effective on perennial grass varieties for example Bermuda, Zoysia or Paspalum that grow by means of rhizomes. (Stems that grow horizontally under the earth) These often develop extensive and deep root systems, enabling them to recover from the results of the scarifying. Conversely, great care has to be taken with grasses which have shallower root systems and propagate by stolons. (Stems that grow horizontally, over the earth)
Shortly after the de-thatching/scarifying, the yard ought to be fed with a balanced fertilizer, comprising the three macroelements; nitrogen, phosphorous and potassium. For environmental reasons, easily soluble fertilizers for example Ammonium Sulfate aren’t recommended now, but outstanding results can be gotten from slow or restricted release fertilizers.
