The Scotts Turf Builder THICK'R LAWN Sun & Shade is a 3-in-1 product designed to improve thin lawns by providing grass seed, fertilizer, and a soil improver. This combination helps create a thicker and greener lawn, especially beneficial for areas with varying sunlight. It claims to deliver up to 50% thicker grass with proper care, making it a promising option for homeowners looking to enhance their lawn’s appearance and health.

The product covers a sizable area of 4,000 sq. ft., making it suitable for medium to large lawns. It's designed for application in the spring and late summer or early fall, aligning well with common lawn care schedules. The slow-release formulation ensures that nutrients are steadily supplied over time, promoting long-term growth and root development.

While it covers both sun and shade areas, results can vary depending on the initial condition of the lawn and proper application. Some users might find the requirement for twice-yearly application labor-intensive. This product is ideal for those who want a comprehensive lawn care solution that addresses seeding, feeding, and soil improvement in one package.

Scotts Turf Builder Starter Food for New Grass Ready-Spray is a convenient liquid fertilizer designed to help newly seeded lawns grow quickly and healthily. It's easy to use since you can feed and water your lawn simultaneously, which is great for beginners or those who want a hassle-free experience.

The product is suitable for all grass types and covers an area of 600 sq. ft., making it perfect for small to medium-sized lawns. The ready-spray application method ensures even distribution without the need for additional equipment, which simplifies the process significantly.

The product’s weight (2.8 pounds) and relatively small coverage area may require multiple bottles for larger lawns, potentially increasing the cost. As a quick-release fertilizer, it provides immediate nutrients to new grass but may need reapplication more frequently compared to slow-release options. Scotts has a good reputation in lawn care, making this a reliable choice for anyone starting a new lawn or reseeding an existing one.

The Scotts Natural Lawn Fertilizer is a solid choice for those looking to maintain a healthy and green lawn naturally.

This convenience makes it a great option for families. This product is also OMRI listed, meaning it meets organic standards, making it a good choice for environmentally conscious users.

It can be applied in any season and works on any grass type, providing flexibility and ease of use throughout the year. The granules form allows for even distribution across your lawn, promoting consistent growth. The weight of 29.1 lbs might be a bit heavy for some users to handle comfortably. The coverage of 4,000 sq. ft is adequate for medium to large lawns, but may not be sufficient for very large properties without requiring multiple applications.

This fertilizer offers natural and safe lawn care with the convenience of all-season application, though its lack of weed control could be a potential drawback depending on your specific lawn care needs.
