it’s a ready- and easy-to-use supplement, studied on purpose for bonsais. The dispensing phial allows a slow but continuous release up to 15 days.
How to use
cut away the tip of the cap with the help of scissors and insert the phial upside-down into the previously moistened soil, at least 2-3 cm deep. Use one phial for 20-30 cm diameter pots, 2 phials for 40-50 cm pots and so on.
