Picking Out Weed And Feed
Since this blog is geared more toward southern lawns I'm going to go ahead and assume that you are using weed and feed on a southern turf grass (Bermuda, Centipede, Zoysia, or St. Augustine), or Bahiagrass (more rare). I'm sure most of you have used or heard of Bonus S by Scotts, which is the most popular weed and feed product out. You can buy the name brand stuff online but if you are going into your local box store, it is perfectly fine to go with the store brand version of weed and feed. The Scott's brand may be marginally better, but it will not be noticeable and for the price of the store brand, it's really not worth spending the 25-30% more on the Scott's, but if that makes you feel comfortable go for it.
3 Main Store Brands Compareable to Bonus S.
- Walmart - Expert Brand
- Lowe's - StaGreen Brand
- Home Depot - Vigoro Brand
All 3 of these store brands come in a "purple bag" southern weed and feed mix and will be comparable to the more expensive Bonus S.
*Note: Do not use any of these purple bagged products on bahiagrass, you will need to find a weed and feed geared toward bahiagrass. Vigoro makes a bahia weed and feed that can be found at Home Depot.
Always use a granule when you want to do a weed and feed. There are no good liquid weed and feeds out there so don't be tempted to try one of them just for ease. Every liquid Weed and Feed that I have seen for sale only contains nitrogen and an herbicide, no potash or phosphorus which kind of negates the purpose of a weed and feed.
How To Apply Weed And Feed.
One of the common misconceptions about applying weed and feed is when to do it. Most people start putting their weed and feed down in march which is way too early in most cases. When it comes to spring time weed and feed applications the date is far less important than the temperature. Most of the time March and early April are too cool to start applying your weed and feed. You want consistent days above 80 degrees before you put it down. Always put your weed and feed down in the morning when the grass is wet either from the morning dew or from a quick rinse down with a hose or irrigation system. When speaking with people who have had trouble with weed and feed or claimed that it "just made my weeds grow", it became apparent that they put their weed and feed down on dry grass, or put it down and then watered it in immediately.
Steps to put down weed and feed
- Use in the morning.
- Make sure that the grass is wet.
- Apply product using a broadcast spreader without overlapping.
- Wait at least 8 hours and then water the product in.
- Do NOT do multiple applications in a short period of time.
The reason that you want to put weed and feed down on wet grass and then wait to water it in is because you want the active ingredient (herbicide) to stick to the broadleaf weeds in the yard. If you put it down on dry grass, or water in immediately you have just wasted the herbicide portion of the weed and feed and essentially just applied a fertilizer which in turn, also makes your weeds grow.
