Applying fertilizer is a great way to ensure healthy grass growth that leaves your neighbors green with envy. Before you start calling lawn care professionals, familiarize yourself with these fertilizer questions that your pro is likely to ask so you’re ready to hit the ground running.

1. When do you want to start services?

Most local lawn fertilization and treatment specialists recommend starting lawn fertilization routines in late winter or early spring, usually with a pre-emergent to prevent weeds from sprouting. Grass also needs different nutrients at different times of the year, so your pro will tailor your fertilizers to your climate and type of grass. High-nitrogen fertilizers are great for establishing healthy top growth that helps prevent weeds in the spring, while nutrients to promote root development are best in the fall before winter dormancy.

2. How often do you want to fertilize your lawn?

Your pro will need to know how often you want to schedule services, as this will affect not only their schedule and pricing but also the amendments they add during each visit. For example, liquid fertilizers provide an instant boost to soil nutrients but wash away quickly, so they’re best for weekly or monthly treatments. Treatments once or twice a year will require slow-release fertilizers.

3. How large is your lawn?

Landscaping professionals price​​ services based on the size of your yard. Lawn fertilization costs between $0.02 and $0.05 per square foot. Your pro will use your lawn size to provide an accurate estimate and determine which equipment is best for spreading the fertilizer.

4. Do you have children or pets that use your lawn regularly?

Some fertilizers contain herbicides and pesticides, which can fertilize grass and help prevent lawn problems. Your pro will ask if you have children or pets who will use your lawn frequently, and they should choose the products they use based on how safe they are for kids and animals.

5. Do you need any other lawn care services?

Lawn fertilization is rarely a standalone service, so your pro will ask if you need other amendments or maintenance options. Depending on the landscaper you hire, you can also opt for routine mowing and edging, pest control, weed control, flower bed mulching, tree and plant care, and even one-off hardscaping and xeriscaping installation.

6. What type of grass do you have?

Your pro will need to know what type of grass you have to develop the most appropriate fertilization schedule and specific amendments. If you’re not sure, your professional may need to inspect your property to see before you get started with services.
