"We use Doug regularly to fertilize our trees and shrubs, and to keep pests like lace bug and root weevils under control. He is knowledgeable, punctual, professional, and responds quickly to address any problems that crop up. He even saved our maple tree from verticillium wilt and gave it a good pruning. We highly recommend him."

Lawn Fertilization and Treatment questions, answered by experts

If your lawn has a higher pH than recommended for your type of grass or it looks yellow, sulfur can help. If your lawn is slow to grow and not very lush, it could also benefit from a  higher sulfur content. Sandy soil is especially vulnerable to sulfur deficiencies.

The best fertilizer for early spring is an organic slow-release fertilizer that sets up your lawn for continued good health and vigorous growth throughout the whole growing season. If your lawn is particularly neglected or has specific issues, you may need an application of quick-release fertilizer alongside a slow-release one for an immediate boost. 

You can fertilize right after mowing as long as you've collected the clippings. If you leave grass clipping, they can form a mat that prevents the fertilizer from reaching the soil. Plus, grass clippings are rich in nitrogen, so if you leave them and then apply fertilizer, you can end up with too much nitrogen in the soil.

DIY solutions often lack precise formulation and distribution, potentially leading to lawn damage. Professional treatments optimize results with targeted applications.

At its core, soil pH is a measure of how many hydrogen ions are present in your soil. In highly acidic soil (low pH), plant growth is difficult due to reduced microbial availability in the dirt.

In highly alkaline soil, plants may struggle to grow due to iron deficiencies. In either case, a lack of balance deprives grass or plants of some key nutrients they need to grow.

A pH reading of 6 to 7.5 is ideal for most plants. Slight acidity is, generally speaking, less of an issue than slight alkalinity. Many plants can still thrive in slightly acidic soil.
