â€œWhy Do Bonsai Need Fertilizer?
Bonsai containers are a man-made environment. As such, they require you,
in order to maintain the health and development of your bonsai, to provide,
in addition to frequent watering, a regular dose of fertilizer to the soil or
What Type Of Fertilizer Should You Use?
Feed your bonsai with a balanced fertilizer, 20-20-20, at quarter strength,
every other week. The numbers 20-20-20 are the percentage, by weight, of
the N-P-K (nitrogen, phosphorus, and potassium) contained in that fertilizer.
These elements, in addition to minor or trace elements, are necessary for cell
division and enzyme processes that allow photosynthesis and the resulting
growth to take place.
What Does N-P-K Stand For & What Does It Do?
N – Nitrogen is responsible for the size and amount of new growth and, to
some extent, the green color of the leaves. Nitrogen is required for cell
division and, also, protein manufacturing. P – Phosphorus is also necessary
for cell division and is associated with good root growth and flowering. K –
Potassium activates cell enzymes and is related with overall healthy cell
â€œBonsai Fertilizer Notes
â€œThat bonsai trees, as well as, other trees and plants, are capable of
absorbing synthetic nutrients through their foliage – oftentimes more readily
then through their roots. When foliar feeding, be sure to carefully follow all of
the manufacturers’ instructions and never foliar feed in direct sunlight, as
leaves can burn quickly. While applying synthetic nutrient, use a spray to mist
the foliage and be sure to check the undersides of the leaves, as there might
be ‘pests’ hiding. This is also an ideal time to check the wires and make sure
that they are not digging into the bark.â€
