Myth:
Organic fertilizers are better than synthetic.
Fact:
Organic fertilizers improve soil structure, but synthetic fertilizers offer more precise nutrient ratios and quicker results.
Myth:
Fertilizer is “plant food.”
Fact:
While it’s not wrong to say fertilizer is food, it’s more of a nutrient supplement, kind of like vitamins. Plants technically feed themselves through photosynthesis.
Myth:
Fertilizer fixes weak plants.
Fact:
Fertilizer is a component for strengthening plants, but it’s not the end-all-be-all remedy. The common culprits for dying plants are improper watering, bad light, temperature, and poor soil.
Myth:
Lawn fertilizer is the best cure for brown grass patches.
Fact:
While fertilizer feeds grass, it doesn’t sprout fresh blades. Bare or brown patches demand grass seed and regular watering.
Myth:
All-Purpose fertilizer is best for lawns.
Fact:
While balanced-formula fertilizer is better than none, it’s not the best option. Lawns generally require higher nitrogen levels for green growth. All-purpose fertilizer contains high phosphorus levels, which is essentially unnecessary for established lawns.
Liquid fertilizer is applied as a solution that can be sprayed directly onto plants or distributed through irrigation systems using injection or fertigation equipment. Because nutrients are already dissolved, they are absorbed quickly by both plant leaves and roots.

Granular fertilizer comes in dry pellets or particles that are spread across soil or turf. After application, irrigation or rainfall dissolves the granules, gradually releasing nutrients into the soil.
Founded in 1918 (yes, that’s over a hundred years ago), Grow More fertilizers have been trusted by professionals for their consistency and high-quality, research-driven formulas. Grow More has always put innovation at the forefront and are a leading fertilizer manufacturer in over 30 countries. From organic fertilizers to liquid formulas, and rose fertilizer to all-purpose fertilizer, Grow More continues to meet the needs of thousands of different plants, flowers, and grass types, keeping pace with new developments and discoveries.
Yes, Grow More fertilizers and pets can be a dangerous combination, especially if ingested in granular form. Diluted fertilizer on grass usually only results in minor stomach pains, but raw granular fertilizer can lead to severe health issues, including muscle tremors and pancreatis.
For general growth, the best Grow More fertilizer for hydroponics is a balanced, all-purpose Grow More 20-20-20 fertilizer , while formulas with high phosphorus and potassium levels are best for early growth and root development.
For orchids, it’s best to use fertilizers with elevated nitrogen levels, such as Grow More orchid fertilizer designed for rapid vegetative growth and foliage development. Simply mix 1tsp per gallon of water to boost foliage.
When it comes to bamboo care, few compares to Grow More Lucky Bamboo fertilizer. A specialized 2-2-2 balanced NPK fertilizer, it leads to green leaves and sturdy growth and is only used once a month. Simply mix with water and apply it monthly to keep bamboo plants healthy without overfeeding.
