Organic Fertilizers
An organic fertilizer feeds your plants while supporting healthier soil over time. Instead of delivering nutrients all at once, organic products break down gradually through natural microbial activity, providing a steady source of nitrogen, phosphorus, and potassium. Many gardeners and landscape professionals choose organic fertilizers because they improve soil biology while reducing the chance of nutrient runoff.
You'll find products from trusted brands like Down to Earth, Nature Safe, FoxFarm Happy Frog, and Drammatic for lawns, vegetable gardens, flower beds, trees, and shrubs. Organic options work well for long-term soil health and are especially popular for residential landscapes, edible gardens, and sustainable lawn care programs.

Synthetic Fertilizers
Synthetic fertilizers are a type of inorganic fertilizers that make nutrients available quickly, making them a practical choice when lawns or landscapes need fast results. Professional landscapers often choose these products because they deliver consistent nutrient analysis, predictable performance, excellent coverage across large properties, and nutrient availability that can promote rapid growth. Faster-acting conventional products can also wash away more quickly and may need repeated applications.
You'll find professional products from Lebanon ProScape designed for turfgrass, athletic fields, commercial landscapes, and residential lawns. Many blends are formulated for seasonal feeding schedules and can help improve color, density, and overall plant vigor when used according to label directions.

Granular vs. Liquid Fertilizers
Both granular and liquid fertilizers have their place depending on your application. Fertilizers are sold as solid or liquid products, and most fertilizers are used in solid form. Granular fertilizers are the most common choice for lawns because they're easy to spread evenly, typically provide longer-lasting nutrition, and are generally easier and more economical to ship and store. Many professional products also include slow-release technologies that continue feeding over several weeks.
Liquid fertilizer acts more quickly and is often used when plants need nutrients during active growth. They're also useful for foliar feeding and smaller garden applications where precise application matters, and in some situations foliar applications can reduce the total amount applied. Choosing between granular and liquid products depends on your goals, the size of the area, and how quickly you want results.
Slow Release vs. Quick Release
A slow release fertilizer provides nutrients gradually over weeks or months instead of all at once. That longer feeding window can reduce the number of applications needed during the growing season while helping maintain more consistent plant growth. Products featuring Lebanon ProScape MESA technology or methylene urea release nitrogen over an extended period for dependable performance.
Quick-release fertilizers deliver nutrients immediately and are often selected when turf or gardens need a faster response, but too much fertilizer can stress plants and increase runoff risk. Many landscape professionals combine both approaches throughout the season depending on plant health and growing conditions. Nature Safe 10-2-8 and several Lebanon ProScape products are excellent examples of slow-release feeding programs. When products are overapplied, excessive nutrients can be toxic to plants.
Choosing the Right Fertilizer for Your Project
Best Fertilizer for Lawns
The best fertilizer for lawn projects depends on your grass type, soil nutrient levels, growth stage, and the time of year. Soil testing before fertilizing helps match nutrient needs more accurately. Cool-season lawns common throughout Colorado benefit from balanced feeding schedules that support root development while maintaining healthy growth.
Nature Safe 10-2-8 works well as an all-season option for many lawns, while Lebanon ProScape 19-0-6 combines feeding with weed control for appropriate applications. If you prefer organic lawn care, Down to Earth Bio-Turf provides natural nutrients that help build healthier soil while supporting thick turf. Whether you're maintaining an established yard or managing commercial properties, selecting the right lawn fertilizer improves both appearance and long-term performance.
Fertilizer for Flowers and Gardens
Flower beds, vegetable gardens, and ornamental landscapes all have different nutrient requirements, and vegetables often benefit from more targeted feeding through the season. Choosing the right fertilizer for flowers helps support stronger blooms, healthier foliage, and improved root development, and when used correctly can improve the yield and quality of fruits and vegetables throughout the growing season.
Popular options include Down to Earth Flower Garden 2-6-5, Down to Earth Rose & Flower Mix 4-8-4, and FoxFarm Happy Frog Fruit & Flower. These blends provide balanced nutrition for annual flowers, perennials, shrubs, and edible gardens while supporting healthy soil activity.
Starter Fertilizers for New Lawns and Sod
A quality starter fertilizer gives new grass the nutrients needed to establish strong roots. Unlike maintenance fertilizers, starter blends contain higher phosphorus levels that encourage early root development while supporting healthy top growth.
Nature Safe 5-6-6 and Down to Earth Starter Mix 3-3-3 are excellent choices when installing seed or new sod. If you're planning a new lawn, pair your fertilizer with our selection of bluegrass sod for a complete installation solution.
Understanding Soil Amendments
What Soil Amendments Do
While fertilizers provide essential plant nutrients for improved plant growth and health, soil amendments improve the growing environment itself. Materials like perlite, vermiculite, compost, humic acids, and soil conditioners help improve drainage, water retention, aeration, and soil structure. Better soil allows roots to grow more efficiently and helps nutrients remain available to plants.
Products such as Whittemore Perlite, Whittemore Vermiculite, Down to Earth Humic Acids, and Organix Revive are designed to improve soil quality over time rather than simply supplying nutrients. If you're rebuilding planting beds or preparing new landscapes, combining fertilizers with the right amendments often produces better long-term results.
