    Fertilizer with calcium + sulfur

    Are fertilisers with sulfur and calcium necessary? Bad? I have one with 120g/kg of Sulfur and 14g/kg of calcium which I’m considering purchasing. It’s pelletised and applied once monthly. Our tap water has around 120 - 180 mg/litre CaCO3. Not sure about sulfur.

    Fertiliser choice

    Is a high-dilution/daily fertilizing schedule advisable?

    I have been watching some bonsai people saying that the use of highly diluted chemical fertilizers every day - mixed with the water in a watering can - can give us better results than the same amount of fertilizer used in the regular dilution (as suggested by the label) every fortnight, for...

    Dawn Redwood foliage problem.

    Hi all! Just a quick question. As you can see from the photos some of the foliage on my dawn redwood is turning reddish brown. :( Could it be too much fertilizer? I hope that it’s not something worse. I fed it with an 18-4-10 slow release fert in teabags for about a month and a half, and then...

    Fertilizer NPK Ratios

    So this question is perhaps pretty basic and I have an idea as to the answer if my assumptions are correct, but when someone advises for something like a 9-9-9 NPK ratio fertilizer, is that all in percent volume? For example, 9% of the bottle is Nitrogen, 9% is Phosphorus, 9% Potassium? I assume...

    First Fertilizing

    I haven't done any fertilization yet. I have some liquid, synthetic fertilizer (15-15-15) and all of my trees are in development, in five-gallon containers with coarse, mostly inorganic substrate. I chose liquid fertilizer because I largely sifted all the fine particles out of my substrate and...

    Tap vs. Distilled vs. R. Osmosis water

    I’ve done some searching on here can’t can’t seem to find the info I’m looking for... As I understand things, Tap water is the worst type of water to use for trees. A bunch of dissolved solids that can accumulate in soil and prevent the plant from absorbing nutrients. Distilled water is...

    Liquid fertilizer killing moss?

    I was wondering if anyone experienced moss dying from continual liquid fertilizer application? The fertilizer I use vacillates between fish fert and a 10-10-10 chemical 2-3 times a week at concentrations higher than stated on the packaging but way lower than I've seen seasoned enthusiasts...

    It is a Delonix Regia that I am keeping indoors until the weather permits otherwise. This is the first tree seed that I’ve planted. Also, what kind of fertilizer should I use and should I put it in another “pot”. This one came with the kit and I’m not sure how sufficient it is. I have...
