Bonsai trees need food too! Below you will find some general guidelines
to feeding your bonsai. If you don't already have a bonsai tree then
you can use the directory to the right to purchase one online or to
buy supplies for the tree you already have.
To keep your bonsai in good shape and maintain healthy growth requires
regular feeding at the right time of year with the correct fertilizer.
Fertilizer must be continually replenished due to a certain amount
being washed out each time the plant is watered. You can get many
different types of fertilizers, in a variety of forms. The most common
is pellet-form (such as 'Osmocote'). This is a slow-release fertilizer
which will take care of your bonsai tree's feeding requirements for
several weeks at a time and is probably the type of fertilizer most
used by bonsai enthusiasts. Soluble powder and liquid feeds are also
used for rapid effect over short-term periods. These are applied to
the soil with a watering can and are used up relatively quickly.

To understand exactly how your bonsai tree should be fertilized,
you must be able to understand the basic make-up of fertilizers. Most
fertilizers contain three basic elements: Nitrogen (N), Phosphorous
(P) and Potassium (K). Nitrogen is an essential ingredient for leaf
and stem growth. Too much nitrogen however will make the bonsai tree
produce long, stringy growth. Phosphorus encourages healthy root growth
and helps the growth of new buds, whilst also protecting against disease
and unfavorable winter conditions. Potassium (potash) encourages the
formation of flowers and fruit, and is vital in the fight against
disease.

As a general rule, feed your bonsai tree from early spring to late
summer. Use a balanced fertilizer with a fairly low nitrogen content
year round, and one with as little (or no) nitrogen as possible in
autumn to aid the tree (so the tree can retain its energy) through
the winter. If you cannot find a fertilizer that's doesn't have nitrogen
in it, do not fertilize your bonsai during the winter. Most commercial
fertilizers contain all three main nutrients plus some trace elements.
One type of fertilizer usually only obtainable from bonsai nurseries
has an NPK (nitrogen, phosphorous, potassium) ratio of 0:10:10. This
is an autumn feed (containing no nitrogen) which will harden off the
current season's growth to make your bonsai tree ready for the long
months of winter.
