Over the past month, I observed some leaves losing their green color and turning yellow (shown below). I am not sure why but the reason can be lack of sunlight, too much watering, or low temperature.
I discussed the issue of falling leaves with a friend at the office and learned about his odd experiences from the world of bonsai. He bought 4 bonsai trees and 3 died one after the other.
The first one died due to over-watering, the second died because of lack of watering, third died due to lack of sunlight, and finally, the fourth one is recovering as he placed the pot under fluorescent light by accident.
Sometimes I fear my bonsai may die but I do see a sign of improvement as well. As shown in the image below, sometimes I see roots coming out of my bonsai pot, which I prune every now and then.
Along the way, I also heard many YouTubers talk about fertilizers and its importance. To be honest, I thought the soil given to me by nursery was enough and will last a year or two.
Upon researching further, I came to know about NPK mix, which is nitrogen, phosphorus, and potassium respectively. The nitrogen helps in growth of leaves, phosphorus enables root growth, and potassium induces flower/fruit growth.
As I am new to gardening so I simply ordered two different NPK mix. I ordered Bloom Buddy All Purpose Plant Feed from Rajshree Biosolutions and NPK 20 20 20 water soluble fertilizer from Shivi Products to ensure my bonsai tree gets enough nutrients.
Let’s do some math before we proceed further. Ideal for most home gardens, the above-mentioned product from Rajshree Biosolutions contains 2.5% Nitrogen (N), 3% Phosphate (P), and 3% Potassium (K).
For people who take gardening seriously, Shivi Products’ water soluble fertilizer has 20% nitrogen, 20% Phosphate, and 20% Potassium, which can give a tremendous boost to Bonsai and other fruit/flower-bearing plants.
After few YouTube videos, I came to know that it is essential to use plant feed along with NPK 20 20 20 as Bloom Buddy comes with essential micro-nutrients which are important for the growth of indoor plants.
I added half a scoop of Bloom Buddy plant feed and a quarter teaspoon of NPK 20 20 20 in the Ficus Microcarpa. After a few days, I saw growth activity in the tip of the branch I pruned last month.
In February, I also decided to use one packet of Monkey Pod Tree / Acacia Preta seeds. After soaking the seeds in warm water overnight, I planted them in a pot containing just garden soil.
To keep the surface moistened, I sprayed NPK water every morning. After observing that by morning the surface looked really dry, I started spraying water before sleeping as well.
