The immediate development of a carpet of green over the surfaceof a lawn area is no indication that a permanent lawn has been es-tablished. The construction of a permanent lawn which requires onlya normal expense in future maintenance involves not only the questionof selection of grass seed of permanent types but also questions of ade-quate drainage, especially on heavy types of soil, and thorough prepara-tion of the subsoil and the topsoil as a foundation of the lawn. Un-fortunately many persons ignorant of the real requirements of 2permanent lawn give much credit to those persons who are able, by theuse of quick growing and temporary types of grass seed together withclover seed, and quick-acting fertilizers such as sheep manure (whichsoon releases all of its food value and leaves the lawn in an unfertilecondition), to succeed in producing an immediate effect of greenswardin a remarkably short time. The permanent and desirable types ofgrasses will not develop within such a short period, and lawns of thistemporary character, while exceedingly satisfactory during the firstyear, will usually prove unsatisfactory and expensive in their main-tenance cost during the succeeding years. Not only do certain typesof grasses die out due to the nature of the grass and the lack of properfood supply but the lawn is seriously injured during the hot summer |
