fertilizer

Hi everyone, I'm based in Victoria, BC, and have been rediscovering bonsai (after first dabbling with a ficus almost 2 decades ago). I've been trying to learn as much as I can, and wow, there's so much out there now, it's a bit overwhelming! I recently picked up a couple Japanese black pine...

Substrate question with a LOT of background: I started in bonsai 16 months ago (after decades in other horticultural hobbies) and have over a dozen species of Shohin-sized tropicals. I live in Wisconsin, USA (zone 5). Some trees live indoors under good SpiderFarmer lights year-round, others go...

I am going to use the Dyna-Gro Bonsai Pro fertilizer. It says on the back how much liquid to mix into a gallon of water. How often do I water with this mix? Once a week, right? Should I take the environment (grow tent) into account for how much to mix? What do you recommend? Also, it says it’s...

Hey all. I have a ficus religiosa and ficus benghalensis both planted back in November. Just looking for a balanced fertilizer and was wondering if you all can recommend specific brands. Cost isn't really an issue. Thank you in advance!

At the moment almost all of my trees are Prebonsai in large containers so I can grow their trunks and branches as quickly as possible. How would fertilizing differ in this stage from refinement? Would I want a balanced fertilizer in both cases or would a different fertilizer ratio be better for...

I was wondering if there was anyone in the Nordic countries that could point to a high nitrogen fertilizer for trees in development. Don't really speak the language yet and don't know any local brands. I prefer granules but will use whatever need be. Currently been using an organic that is only...

This is the fish emulsion that I have been using for three or four years. It is mostly a mix of fresh water fish, and small crustaceans, all from the Amazon basin. It seems to be working very well, specially when alternating it with some kelp emulsion. What I like in it is the low NPK - which is...

I’m curious if any BNutters have tried experimenting or going from a once a week fertilizing routine, to an injector system, fertilizing with each watering. I recently picked up a fert injector system and a couple of my fellow club members were talking about how they fertilize with it on the...

Hello everyone, I have a Chinese sweet plum for almost a year now. It was always healthy and growing out. Recently, the leaves are tuning brown at the end , leaves seemed to be dry and wilting and in general, complete tree is dropping. I added fertilizer 5-7-4.NPK superbly bonsai last week. It...

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.

I have decided to move over to an organic pellet form of fertiliser. I have narrowed the options down to these two: Npk 24:27:30 https://atlanticfertilisers.co.za/retail-bio-rock-root-builder/ Npk: 27:17:31 https://atlanticfertilisers.co.za/retail-bio-ocean/ Would there be a significant...

Hi 👋 I’m new to the bonsai growing and recently I was gifted with couple of bonsai trees. Searching online I have found one of them is deciduous, one of them is coniferous and other two are tropical indoor. One of my friends suggested to use fertilizer to keep them healthy state. With little...

Whats eating my fert? Im not complaining, quite the opposite Its organic, plant based fertilizer in pellet form. 'Saidung plus'. Applied less than a week ago This pot houses an azalea but azalea roots are around 1/10th of a millimeter in diameter and these are like a 1/100th, I would guess...

Hey guys. I have a satsuki shrub that I’ve been wanting to chop into a bonsai for awhile and I have a general idea as to what shape I’m trying to achieve and everything, but I’m having an issue with timing. I live in zone 9a and people I’ve asked have advised me to not chop until january or...

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...

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...

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...

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...

Hello, I recently repotted my ficus retusa in akadama/lava rock and after it being a bit ropey due to repotting too early, it is now recovering really well. The weather is warming up quite a bit here so I'm letting the ficus have some sun outside in the day for now. With the new soil substrate...

Anyone have any experience with Gaia Green organic 4-4-4 all purpose fertilizer? It's from BC Canada but you can get it pretty much at any LGC across Ontario. It's derived from: Feather meal, alfalfa meal, bone meal, blood meal, glacial rock dust, natural rock phosphate, fishbone meal...

I’m surprised it has already rooted!! A transplant is imminent! I have had this beauty since early January. I took it out of dormancy last week. I just started giving it indirect sunlight outside for about 5 hours a day. I’m going to give it a week and then give it direct morning sunlight for...

Too much fertilizer....

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...

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...

i recently purchased a mature dwarf jade on a whim for my birthday, and have been researching as much as i can ever since. i think i’m getting the hang of it in general one thing i am struggling to find consistent answers on is fertilisation. from the garden centre i also purchased a small vial...
