Directions for Use
Test fertilizer first at the lowest concentration on a small sample before using on all plants.
- Apply before watering to allow fertilizer to disperse throughout roots and soil. May also be used as a foliage spray.
- Shake well before each use. Prepare for one application only — do not store diluted fertilizer.
- Use every 3–4 weeks for any one fertilizer.
Mix outdoors or in a well-ventilated area.
General Fertilizing
1–2 tablespoons (15–30 ml) per gallon of water. Feed every 2–3 weeks. Do not over water.
Soil Drench
2–3 tablespoons (30–45 ml) per gallon. Apply to roots on a monthly basis during the growing season. Ideal for heavy feeders — fruits & vegetables.
Foliar Feed Spray
1 tablespoon (15 ml) per gallon. Apply by misting during the cooler parts of the day (evening and early morning).
Orchid Fertilizing
Apply only when plants are in active growth or immediately after re-potting. Saturate roots with plain water before applying. Use ½ teaspoon (2.5 ml) per gallon — apply to roots by misting or allow to flow slowly through growth medium. Frequency depends on orchid type.
Compost Supplement
Half a cup (120 ml) per gallon added to a compost pile acts as a catalyst, aiding to heat the pile.
The aroma of fish & seaweed fertilizer will disappear in a few days, as soon as the liquid fertilizer fully seeps into the soil and microbes begin to break down organic compounds into essential nutrients.
