Apex Line of Nursery Fertilizers

Nurseries require a variety of unique formulations to meet their specific growing needs. You need long-lasting, controlled-release fertilizers that reduce labor costs and offer the ultimate level of application safety. With APEX® fertilizers, you get what you need in plant nutrients and nutrition throughout the entire growing season in any growing condition. Running a nursery operation can be unpredictable, your fertilizer shouldn’t be.
The APEX® line of fertilizers feature application specific formulations that incorporate GAL-XeONE™ controlled-release technology. The coating process of GAL-XeONE™ enables consistent, predictable nutrient delivery for up to 18 months, and APEX® fertilizers eliminate the need for top dressing on most plants.
APEX® delivers plant nutrients through a solute concentration gradient permeation process that is unaffected by soil moisture, microbial activity, and pH levels which makes it more consistent and reliable.
