To be short: I have a bonsai in distress which I believe is Fukien (leaves with white spots/dents and little hairs, little fruit grouped 2 or 3 together).
I received this bonsai a little while ago (about 1 month and half). In the past I had another bonsai (exact same species I believe, the leaves would have bumps on their surface when drying) which unfortunately died due to bad care... I don`t want to be a bonsai killer.... Help...
For the beginning I was watering the plant each 2 days. 2 weeks after receiving it I saw that the substrate did not want to accept any more water (like hydrophobic) and had some mold-like (white-ish) crust at the top. I digged (like 3-5mm deep) that crust and everything is fine ever since (no more crust, accepts water just nicely).
I admit that I neglected the bonsai for about 3-5 days last week, but it sterted loosing leaves about a week after I got it.... It also has some new fresh leaves, healthy-green (I thought it was a natural process of loosing old leaves and growing new ones), but I saw lots and lots of yellowish leaves this morning (some brownish on sides) and they fall as soon as you touch the bonsai pot.....
I am using some special bonsai fertilizer mixed together with little cactus fertilizer and little orchid fertilizer. I only water the bonsai by spraying on the substrate (when I use solution with fertilizer) and by also spraying on the leaves (when I use plain water). I have no schedule like when to use fertilizer and when not to. This morning it is the 2nd time I use fertilizer in a row. I use tap water which sat for about a day or so in an opened bottle (tap water is very drinkable (like very good) in my area).
I live in the Northen hemisphere (47 degree north, Cluj-Napoca, Romania). I keep the bonsai indoors, large S-WWW window, direct sun for like 2-3 hours this time of the year. Lately (last 2 weeks) it was very cloudy, but it is sunny for 2 days now.
What other details should I mention? I have the impression that I am forgetting something....
Anyway, I suspect I have over-watered the bonsai (based on what I have read so far on other forums)... The substrate smells like a wet basement but there is no mold. This is the first time I lifted the bonsai by the trunk (out of its pot).
Can someone please help me?
Thank you very much!
