"We were initially happy with this company- they were efficient and priced on the low end, and very nice! The team came, mowed, and pulled away everything dead, so at first, things looked nice and clean. Then slowly over the months, our plants started dying, and then were ripped out once they were dead. So now, we have very few plants. It just seems like very little care or pride is put into the work; the time spent only 37 minutes (we timed it) last time on our large yard. If a potted plant is knocked over from the wind, they didn't even bother to put it upright. No watering, fertilizing, pesticides- just mowing and pulling away dead plant material."

Lawn Fertilization and Treatment questions, answered by experts

Yes, after the lawn is overseeded post-aeration, most of the seed germinates in the aeration holes. This leaves the soil undisturbed while lush and healthy grass will grow in the holes' place. The point of this is to create extra turf density in areas that really need it, such as a large patch of dead grass where a shed used to be.

Sugar is good for plants, despite limiting nitrogen absorption. However, the sugar that is healthy for plants is typically the same sugar created by plants as part of photosynthesis. In other words, table sugar is not good or bad for plants on its own, just keep track of nitrogen levels in the soil. But don’t worry, sugar won’t kill your grass.

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. 

The best time to apply fertilizer to your lawn is in early fall, though some climates necessitate a different schedule. In most cases, avoid fertilizing late into fall, as this opens up your yard to winter injuries and poor health (though this is a great time to kill weeds.) You should avoid early spring fertilization, as this helps the grass leaves grow, but at the expense of developing root systems. Remember to water your lawn after fertilizing to increase its effectiveness and reduce the likelihood of runoff during a rainstorm. 

The best time to fight crabgrass with pre-emergent herbicide is when forsythias tend to bloom. In the mid-Atlantic region, this is usually between April and May. Even if you're late to apply the herbicide, it’s effective as long as the crabgrass plant has fewer than five leaves.
