Understanding St. Augustine Grass
St. Augustine grass is a warm-season grass known for its dense, lush growth and tolerance to heat and humidity. However, like all grass types, it’s susceptible to weed invasion. Weeds compete for nutrients and water, making it essential to use a weed and feed to control their growth and promote a healthy lawn.
Choosing the Best Weed and Feed for St. Augustine
Nitrogen Content
The most important factor to consider when choosing a weed and feed is the nitrogen content. Nitrogen is a crucial nutrient for all plants, including St. Augustine grass. It helps promote healthy growth, green color, and overall vigor. Look for products with a nitrogen content of at least 20%.
Controlled-Release Formula
A controlled-release formula ensures that the nutrients in the weed and feed are released gradually over time. This prevents the grass from getting too much fertilizer at once, which can lead to burning or nutrient overload. Opt for products with a slow-release or controlled-release formula.
Herbicide Type
The type of herbicide used in the weed and feed will determine which weeds it’s effective against. For St. Augustine grass, look for products that contain herbicides like 2,4-D, mecoprop, or dicamba. These herbicides target broadleaf weeds, which are the most common type of weed found in St. Augustine lawns.
