Weed Services questions, answered by experts

You should add 1 to 4 inches of mulch, depending on your garden type and needs. Keep in mind that no amount of mulch can completely prevent weeds, but a heavier coverage (closer to 4 inches) can suppress weeds enough that you are only seeing them sprout every few weeks. Finer mulch prevents weeds more effectively than large mulch, so if you’re using mulched leaves or shredded bark, 1 to 2 inches will likely suffice, while 3 to 4 inches is best for larger mulch, like bark chips or straw.

There are a few things you should ask a weed service company before hiring to ensure you’re choosing the best professional for the job:

  • How often will you apply herbicides?

  • Do you include any spot treatments or manual weed removal in your pricing?

  • Do you offer pet-safe and kid-safe herbicides?

  • What other lawn services can you provide?

  • Do you offer any kind of guarantee for the work performed?

  • Are you properly licensed and fully insured?

  • Do you have any customer references I could speak with?

The best time to hire a weed service company is in the early spring. This allows them to apply a pre-emergent weed killer that stops weeds from taking root, making maintenance for the rest of the season much easier. Following the initial spring application, a monthly service through the summer and early fall is a good idea for ongoing weed control. These regular treatments, combined with manual removal or spot treatment, should be sufficient to maintain a weed-free yard. Alternatively, you can hire a professional in the fall for the following year, as some companies may offer better rates on contracts signed before the busy spring season.

Yes, you can typically combine liquid aeration with other lawn treatments. However, follow the specific product's instructions and consider the compatibility of treatments. In most cases, liquid aeration can complement fertilization, overseeding, or weed control programs. Combining treatments strategically can address multiple aspects of your lawn's health and appearance simultaneously. Always read and adhere to the guidelines provided by the product manufacturers to ensure safe and effective application.

The hydroseed mix—known as a slurry—helps grass seed take root in many ways. Water combines with the mulch, allowing the grass seed to stay moist while grounded in the soil. The extra fertilizer then provides the boost the seed needs to flourish. In just a few weeks, you'll be ready to break out the lawnmower again.
