Nutsedge, Violets, Nimblewill, Bermuda grass. These nasty lawn weeds that commonly appear in urban lawns are of the most difficult to control. Even synthetic herbicides often require multiple treatments that never get to the root of the problem. Treating a weed with an herbicide is like only treating a symptom of an illness with medication. When a person gets very sick and treats the sickness with medicine that stops coughs and fever without going to the doctor for diagnosis, they often end up sick for much longer. Urban soils are like people with very poor immune systems; they frequently have health problems.
Organic lawn and land care builds the health of the soil over time to resist weed and pest pressure. Most weeds thrive in conditions unfavorable to turf. An organic lawn care program seeks to out compete weeds instead of eradicate them year after year by building the soil and biology. Through a detailed soil test, the use of slow release organic fertilizers, soil conditioners, amendments, and soil building techniques, an organic lawn program gradually changes the chemistry of the soil. Although not an immediate fix as expected with synthetics, organics offer long term results.
Weeds are all symptoms of a larger problem. As many of you may have probably noticed, nut sedge appears in wet, poorly drained soils that are often compacted (ex. around drives, walkways, low lying areas). It is apparent that these conditions affect weed growth and I have seen the evidence.
Example: Two neighboring lawns have completely different weed infestations. In the first lawn hop clover, plantain, and many weeds present in compacted dry sandier soils run rampant. Next door as if a line has been drawn down the property nut sedge has taken over.
Perplexed by how the soils could be so different only inches apart, I discover that the second lawn has been irrigated all summer rain or shine. Mystery explained. Both soils with slightly different conditions have the same problem. The second lawn is watered every other day but the soil profiles are still essentially the same. The result…an endless battle against lawn weeds! As the conditions change or one weed is eliminated another simply appears to take its place.
The soil is the solution!
Organics are a commitment, but they are also an investment in the long term health of your landscape.
