Like many things in life timing matters. If you want a healthy, vibrant lawn year-round, it’s just as important to understand what it needs as well as to understand when it needs it. A foundational link to your lawn’s health is providing protection from the weeds that can threaten its very existence. Weed killers, weed and feed and the timing of it all, however, can be mystifying to homeowners seeking answers.
Common Weed And Feed Questions Deboned
What is weed and feed? Weed and feed is an interchangeable, universal name given to a wide variety of lawn chemicals that have the purpose of strengthening the lawn by killing weeds. It generally improves your lawn’s ability to absorb water and food and adds necessary nutrients which promote healthy growth.
A healthy lawn, in turn, discourages weed propagation, enabling the use of a reduced amount of the product over time. There are many types of weed and feed that we will drill down on for further learnings.
What is the “weed” in my weed and feed? The weed component is comprised of herbicides (typically Dicamba, 2, 4-D and/or MCPP). These chemicals are designed to squelch dandelions, dollarweed and the most common green leafy weeds.
What makes up the “feed” in my weed and feed? The “feed” is a fertilizer. Typically, it is a combo of nitrogen, phosphorous and/or potassium. The blends vary, but all are designed to help your lawn flourish.
How does weed and feed work? Granules are applied to and absorbed by the leaves of the weed but doesn’t kill regular grass (unless too much is applied). In addition to the granular form, liquid forms are available that can be applied with a sprayer.
What is pre-emergent weed and feed? Pre-emergent weed and feed, as the name implies, targets weeds before they appear. Pre-emergent weed and feed does not control existing weeds. Annual applications over the target area for best results. Water in your pre-emergent weed and feed to activate the herbicide and create a barrier against weeds before they grow.
What is post-emergent weed and feed? Post-emergent weed and feed is the most common form for ridding weeds from lawns. When you already have weeds, the post-emergent weed and feed varietal is in order. Using a mixture of chemicals, they kill the weed and keep it from growing back.
How do seasons impact my weed and feed strategy? To be effective with your weed and feed strategy, you need to get the timing right. As a rule of thumb, time the application of weed and feed with the fertilization of the lawn during the last week of March or early April.
Keeping weeds out of your lawn can often be a chronic struggle that requires a strategy that is comprehensive and continuous. Understanding when to use pre-emergent weed and feed versus post-emergent as well as getting the timing right can be the winning combination to help you reach the finish line.
