Weeds also can be controlled naturally 2 ways. Organicly and Culturally
Organic weed control
Soil pH is one of the the most important weed control factors. Most weeds thrive in soils with a pH of 7.0 or higher. Adjusting the soil pH to the ideal pH for the turf will greatly reduce lawn weed presence.
Soil Conditioning for Turfgrass
|Grass pH Ranges|
|6.7 – 6.8|
*****IAL & CREEPING
|BERMUDA HYBRIDS & COMMON|
|6.5 – 6.6|
|5.0 – 5.1|
|FESCUE RED & CREEPING|
|7.0 – 7.1|
|6.2 – 6.3|
Only St. Augustine turf has an ideal pH of 7.0.
Lowe's and Wal-Mart both carry easy to use inexpensive (less than $10.00) pH meters.
Soil pH can be lowered using sulfur and iron. Besides lowering pH, these benefit your lawn in other ways.
Iron makes for healthy, dark green growth. As with magnesium, iron is essential for photosynthesis. Iron is necessary for chlorophyll formation, and without it, plants wouldn’t be able to carry out essential cellular functions.
One of the secondary macronutrients, sulfur helps plants maintain their dark green color. Mainly, plants use sulfur to create essential proteins. In grasses, sulfur is essential for nitrogen-fixing nodules, and necessary in the formation of chlorophyll. Plants use sulfur in the processes of producing proteins, amino acids, enzymes and vitamins. Sulfur also helps the plant’s resistance to disease, aids in growth, and in seed formation.
Lawn sulfur and iron both come in concentrated liquid forms for easy application.
Cultural weed control
Most weeds do poorly when shaded. Most also have a low growing nature. Mowing our turf at a height above the weed height wil allow your grass to shade and thus, control lawn weeds.
Nature's Lawn has developed an organic weed control product that should be available in all sates next spring.
