At this time of year lawn weeds seem to be everywhere. The best defense against weeds is a well maintained, thick Jonathan Green lawn. After we do our spring clean up of the yard debris it is important that we apply Jonathan Green fertilizer to get the lawn growing. Follow proper mowing and watering techniques. Let’s take a close look at how we can get the weeds under control.
By now you most likely have applied Jonathan Green Crabgrass Preventer plus Green-Up to your lawn. Crabgrass and other grassy weed seeds germinate when the soil temperatures consistently reaches 50-55 degrees. This is soil temperature, not air temperature. If you are not sure when this time occurs, apply Jonathan Green Crabgrass Preventer plus Green-Up when the yellow forsythia blooms appear. Or, you can invest in a soil thermometer and monitor the soil temperatures throughout the spring. Do not place this thermometer too close to the house, place it at least 10 feet away in a landscape bed, it could pick up heat from the foundation.
You could apply Jonathan Green Organic Weed Control plus Fertilizer which contains corn gluten to control both germinating crabgrass and over 20 other grassy and broadleaf weeds. You may need to do this for a few seasons in order to achieve a desirable level of control.
However, if you have not applied any Jonathan Green Crabgrass Preventer plus Green-Up yet it’s not too late! Jonathan Green Crabgrass Preventer plus Green-Up, which contains Dimension (dithiopyr), can be applied up to 4 weeks later than other crabgrass controls and still be effective. Crabgrass plants that have germinated and grown to the three leaf stage can still be controlled if applied in May.
If you applied your Jonathan Green Crabgrass Preventer plus Green-Up in early spring and the season was cool and dry, or you had a large quantity of crabgrass the prior year, consider a second application of Jonathan Green Crabgrass Preventer plus Green-Up to extend the control of this pesky weed. In addition, Jonathan Green Organic Weed Control plus Fertilizer can control and suppress certain broadleaf weeds.
If you mow your lawn at a higher height, say 3-1/2 inches, you can crowd out a lot of weeds. This higher mowing height also promotes a deeper root system making the lawn healthier and better able to withstand heat and drought conditions.
The most visible broadleaf weed in lawns at this time of year seems to be dandelion. The bright yellow flowers stick out ruining the look of a beautiful, lush, green lawn. Last year’s fluffy dandelion seeds establish in the fall; they overwinter and then “take off” in the spring when warmer weather appears. Many times dandelions show up in April and May even before we have our Jonathan Green Crabgrass Preventer plus Green-Up applied! Broadleaf weeds are best controlled with Jonathan Green Weed and Feed or Lawn Weed Control when the target weeds are actively growing. These products need to have good contact with the weed leaf tissue in order to be absorbed for best control.
There are a few tips that are crucial for superior broadleaf weed control. Do not mow the lawn two days before applying broadleaf weed controls; you want the leaf tissue exposed for absorption of the weed control. Do mow the lawn for two days after applying broadleaf weed controls; you do not want to mow off the weed control from the leaf tissue. Apply Jonathan Green Weed & Feed to a damp or sprinkled lawn. This can be done when the early morning dew is still on the ground or you can water the lawn areas to be treated for a few minutes before applications. Do not water the lawn or expect rainfall for two days after applying broadleaf weed control; you will wash off the weed killer and can expect poor results. Do not apply any weed controls if the air temperature is over 85 degrees or you may damage turfgrass.
They say timing is everything; it certainly is when attempting to control weeds.Back
