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.

Technically, dandelions aren’t bad for your lawn, and they don’t directly kill grass. In fact, they appear in areas that are nutrient-deprived, and their long taproots can loosen the soil and bring nutrients closer to the surface. 

However, dandelions do spread quickly, and they can take over your lawn, eventually crowding out grass. This is why a healthy lawn is the best defense against dandelions.

Yellow leaves and stems on your sprouts indicate they’re not getting enough light. Keep them near the appropriate light source and give them as much as they need (they require longer exposure to fluorescence than they do to natural light sources).

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.
