"Talked with the RC office about some fertilizer for some evergreens. Was told the service would take place in the fall. Their service technician calls me the day he?s in my area and says I will be there in 3 minutes. No previous communication about the day of treatment but 3 minutes notice. Logan needs some further instruction on protocol dealing with customers. Not the company I new 20 years ago. "

Lawn Fertilization and Treatment questions, answered by experts

Fertilizing is optional after dethatching. However, the period immediately after dethatching is generally considered the best time to fertilize your lawn because the thick debris is now gone. As a result, applying water and fertilizer as the final steps of dethatching can help to spur incredible growth.

Start your search for a good lawn care company by finding some landscapers in your area; it might be a good idea to research companies that already work on your block, as they’re more likely to be able to fit you into their schedules, given your proximity. Next, conduct a search online to see if they have positive customer reviews, and try to avoid companies that have poor scores or a history of complaints with the Better Business Bureau. Finally, make sure to ask each company about pricing, contracts, scheduling, and any add-on services.

You should put pre-emergent herbicide and fertilizer on your lawn in the spring. Pre-emergent herbicide keeps weeds from taking root. Fertilizer helps your grass to grow lush and dense and blocks future weeds from growing. You can also add amendments, such as sulfur and lime, to enhance your soil quality. 

One of the best ways to soften your grass and prepare it for planting grass seed is aeration. Aerating your lawn will loosen up compacted soil and facilitate a more even balance of nutrients from root to topsoil. We recommend using core aeration methods for the most effective soil-loosening results.

Sugar water helps the microorganisms in the soil break down nutrients, thus helping certain plants grow. In other words, it is okay to water plants with sugar water, but exercise caution and never rely on sugar when fertilizing your grass. Sugar is not plant food and, if applied too liberally, kills the plants you intend to help.
