verseeding is a process that involves spreading grass seed over an existing lawn to thicken and strengthen it. Reseeding usually refers to starting fresh in bare or heavily damaged areas and is often used in spot treatments where the grass has been killed dead. Top soil overseeding combines overseeding with a top dressing of soil for better chance of success and long term growth. Both methods are designed to improve density and overall lawn health.

The best time for overseeding grass in Alberta is late summer to early fall. Warm soil and cooler air temperatures are the ideal conditions for germination. Spring can also work, but with less chance of success depending on summer temperatures; fall overseeding tends to give longer-lasting results.

This step is helpful but not always necessary. Adding topsoil can help in thin or bare areas by providing new seeds with a nutrient-rich base. For many lawns, pairing grass reseeding and overseeding with liquid aeration can help to achieve the best results by creating better seed-to-soil contact.

A professional overseeding service takes out much of the guess work in lawn care by ensuring the right seed mix, even distribution, and proper care instructions. Many DIY attempts struggle to take root because of uneven coverage or poor seed-to-soil contact. Hiring a professional means getting the right tools and expertise to maximize germination and ensure your investment pays off with a healthier lawn.
