Continued success to All at Harp Renewables.
Hi I just wanted to send you some photos of my hanging baskets and containers that I used the Harp Renewables fertiliser on. It's amazing! The hanging baskets are only planted 5 weeks and the large standing flower boxes are between 8 and 9 weeks. Phenomenal growth! ????
Your All-Season Solution
Infusion can be used in a multitude of settings. Its unique formula releases essential nutrients gradually for optimal growth across various domains.

trees & shrubs
Apply monthly, ensuring to spread evenly, keeping concentrated parts away from the plant stem. Mix infusion 2-5 inches deep into the topsoil or compost. Water once applied. Volume application should be 8:1 ratio, 8-part soil/compost and 1-part Infusion.
Infusion is a slow releasing biofertiliser and as such expect a burst of grow by week 3-4 from application.
Store in a dry environment, avoiding exposure to sunlight. Do not store pre-mixed.
