Many plants grown outdoors are watered twice per week. Research has shown, that the application of half ounce of fish emulsion mixed with 1 gallon of water applied twice weekly helped plants grow vigorously.
Try using fish emulsions on flowering plants or as a drench to encourage healthy plant roots.
Check The Percentages
Before feeding plants using fish emulsion, always check the nutrient levels currently present in the soil to avoid overfeeding. Follow the instructions on the packet, if using store brought emulsions.
