Shin Nong's Pro Organic products are 100% natural and organic. They work on all plants from tropicals and shrubs to herbs and vegetables.
Spraying is called foliar feeding, whereby plants absorb nutrients through the stomata (the pores) instead of the soil. Studies show this can be 8-20 times more effective.
Spray every two weeks in the Spring and Summer. Apply on tops and undersides of leaves as well as on stems. No need to spray the soil or when flowering.
Use in the morning or evening for best results. This is because heat causes stomata to close, preventing nutrient absorption.
