For incorporation, blend into growing media to ensure uniform distribution of fertilizer4
Do not over-mix (doing so could damage fertilizer coating)5
Growing media should be used within two to four weeks after incorporating fertilizer6
For top-dress applications, spread fertilizer evenly on container surface (avoid piling fertilizer directly against plant stem)7
Irrigate after application (irrigation frequency and volume should be adjusted during the crop production cycle according to crop type, environmental conditions, and desired soluble salt levels)8
A product trial is recommended before adopting a new fertilizer program or making full-scale changes to standard cultural practices (test several rates on representative plant types)9
Use caution when applying to plants being over-wintered under cover (if you can't monitor soluble salts and/or adjust irrigation practices, avoid Fall and Winter applications10
