Fertilizing Methods:
There are mainly two methods of fertilizing bonsai trees: "Top Dressing" and "Liquid Fertilizer".
1. Top Dressing: This method involves placing solid fertilizer directly on top of the pot. The fertilizer dissolves and is absorbed into the soil when watering.
2. Liquid Fertilizer: After properly diluting liquid fertilizer, it is either poured over the top of the pot with a watering can, or the pot is soaked in the liquid fertilizer.
Fertilizing Timing:
Fertilizing of bonsai trees is mainly done during the following four periods:
1. Base Fertilizer: This is the fertilizer mixed into the soil at the time of repotting.
2. Additional Fertilizer: This is applied from early spring to early summer (around March to June) and from late summer to autumn (around late August to November) to aid the growth of the tree.
3. Thank You Fertilizer: For bonsai trees of flowering or fruiting varieties, this fertilizer is applied to help recover trees that have borne flowers or fruits and have become exhausted.
4. Winter Fertilizer: This is applied in preparation for activities from spring.
Calculation of Fertilizer Amount:
The bag of fertilizer has the distribution of the three elements of fertilizer, nitrogen, phosphoric acid, and potassium, written in numbers. To calculate the necessary amount of fertilizer, it is common to use nitrogen as a standard and fertilize so that "the amount" of fertilizer used x the percentage of nitrogen contained" equals the necessary amount of nitrogen for the crop.
This is the basic method and calculation method of fertilizing bonsai trees. Fertilizing is a very important task for the growth of plants, and with proper fertilization, plants grow healthily and yield good harvests.
