It’s getting hot out there! As the mercury rises, we finish up the first round of fertilization and weed control. This is typically finished by the end of June, sometimes earlier, depending on the weather.

Early to mid June is when most perennial weeds begin rearing their heads. You can expect to see more dandelions and clover in your lawn, as well as ground ivy (creeping Charlie). The weed control we use is different than most. You won’t see immediate reduction in the number of weeds in your yard; instead you may even see those pesky plants growing. That is because the herbicide we use actually grows the plants to death, using up the carbohydrates stored in their roots. Wait two weeks before determining whether your weed control has been effective.

Remember: many herbicides will leach through the soil, attacking the roots of your trees and shrubs. Always make sure you are familiar with all the effects of any herbicide you apply yourself, as well as the proper storage and disposal procedures! If you have questions about these practices, contact the DNR or MN Department of Agriculture.
