What fertilisers do I use on my orchids? When do I fertiliser my orchids and how much do I use? 

Hi Matthew, Thank you for the information on fertilisers. I look forward to trying your style. Many thanks.

I stumbled on your channel a few months ago , I get a big kick out of the channel .I am a beginner but your attitude is great and very informative.don't change.greeting from the states

Thank you so much for advising us on how to use the fertilisers. Much appreciated

That was helpful and very interesting, I thought it was just me that rarely measured things. Thanks Mathew enjoyed the chat.

Such an interresting view on feeding orchids ! Really enjoyed this video (like aal your others I saw) and this made me think about my own way of fertilizing my orchids ! Like you, I believe in alternating fertilizers/tonics and so on ... Just recently added Superthrive to my programme, plus Epsom salts for extra magnesium. Just like you, I don't use caps to measure, but I DO measure TDS, to make sure I don't overfeed/underfeed my plants. Hallo from the Netherlands !

That was helpful thank you. I didn't know that the slow release worked when temperatures rise and also there's no point in adding bloom based unless there's a spike already forming. I was hoping at some time to hear you discuss the use of micorrhizol fungi. I know what it's for but would like to see what it looks like when you unpot one in which it has been growing, during a repot. Thanks again 🤗

Hi Mathew, Finally… I’ve found someone who uses a local fertiliser/tonic etc for our orchids. I did try the whole measuring, water testing and so on but as I have some orchids in leca, some in moss, the rest in bark or coco chips it’s a bit of a guessing game anyway. I have searched the internet for something that will suit my routine, which just seems to go out the window all the time. Bunnings only stock the very basic stuff so that’s what I’m going with for now. Thanks for a very informative video.

Hi Matthew, I have recently subscribed to your vids and find all your information very helpful. Particularly this one on fertilisers. My climate is like yours, I’m down the road in Geelong lol, so finding your vids has been great. For many years , I have grown phals, just this year I’ve bought Cymbidium’s, Cattleya and the other day my first Dendrobium. I sticking to “ hardy “ ones at present 😉 hopefully one day I wish to buy a shade house and expand my collection, I just love all Orchids and seeing your beautiful plants has inspired me.

Thank you for your regular tutorials. I super love the way you talk haha. No idea why! I just smile a lot while I watch. I have a dozen of seedlings that I got for $90. They seem about 2 years old, all of them. I was told I must pot them in the SMALLEST pot I can find to demand them to make new roots. Was told not to fertilize for 6 months? Question is, is Mycorrhizae true? Or Kelp max applicable to seedlings? I am a moss person and I live in upper part of Canada so it can be cold most of the time. Moss doesn't have nutrients so fertilize regularly all year, half strength. I almost rarely use bark. Do seedlings need higher nitrogen so kelp seaweed natural fertilizer is better then?

I have been using Peter's orchid fertilizer ( one for growth and the other for flower) for 25 years now. There is also a new product called SUPPORT that is worm based (made by worms). Out of curiosity, I tried using their products and it does work effectively. Now I make sure I always have this product in my shed. Try it.

beautifully clarified information, thank you so much

What a fabulous tutorial on fertilization, for most any plants! Thank you so very much!!! ⭐💯‼️

This was great. I have fewer orchids and more NOIDs but my fertilising is a similar mix and match system. After seeing an old video of Rick L's where he said something like in nature a " dilute cocktail of nutrients" would wash constantly over the roots, I rotate different types of feed/tonic/flush and my orchids seem to respond very well.

Thanks Matt great info on these fertilisers I'm new to ur channel but c u with Stephen each Friday only had one orchid given to me by a dear friend years ago very unfamiliar territory growing these but I arm joying ur channel & I'll try growing one ! Thanks again Jo-Anne G coast

This was so helpful thanks Mathew I even took notes!

My primary is Peters Cal Mag Special with Black Iron. I also use seaweed,liquid Cal Mag and powdered supplement that adds all the other micro nutrients. In winter I use 100 ppm plus supplements. Spring I use 200 ppm Total. In late spring through mid summer I go to 250 ppm. The exception are the Catasetum when I fertilize I use 250 in late e spring and 400 ppm summer growing time.

Great video mattew

Thank you so much for this really informative video! Really valuable info. I use a lot of seasol on everything in the garden, especially any new plantings. I have quite a few orchid spikes at the moment (also in Melbourne) so I am going outside to check the potassium ratio on all my fertilisers now! Strangely I don’t get much worm juice from my worm farms, but I do use the worm castings and toss them around onto everything in the garden a couple of times a year. By the way I hope that you can get the worm juice stain out of that beautiful riedel glass. 😀

Thank you, my set up is quite similar. So was very helpful.

I found that video very, very helpful, especially “just relax”. Where did you find that lovely terracotta pot with all of the holes?

In Brisbane, only July is where the orchid dont grow much at all. especially the vandas.

Thank You for this video as well as everyone else :)

Hi Matthew, where did you get your watering cans from? They are lovely.

or just half a teaspoon of rose fertilizer 3:1:5 when you remember - and I dilute it in water sometimes

Hi again Matthew, a quick question please, when you repot your kingianum do you add crushed oyster shell because it is mainly a lithophyte? I have watched your video on it but can't remember 😕 I found your gardening channel yesterday and am going to give that a go because although I live in Wales UK, my son lives in Sydney so we visit sometimes😊🤗

In Trinidad, we get osomote but no the sea fertilizer

Do you mix the seaweed or worm tonic with the liquid fertilizer? I really like your way with plants. Thanks!

Hi Matthew, thank you for this very informative video, I watch other Tubers, and some are very, very specific on PPM, checking your water for TDS and so on, no shade to them, but I personally just don't want to do all of that, like you, I am very simplistic in my fertilizing regimen and so far, so good!! Happy Growing!

Thank you Mathew, your videos are very helpful. may i ask do you use rain or tap water?

Hi Mathew. Great information. One of my orchids has just lost her bloom After a few months .i was going to repot her .but iv just nitice shes growing another spike .on her main spike .shall i still repot her . Help im using a seaweed fertiliser which suits me . But thank you .i worry so much about my orchids ?

Hi Mathew, What kind of water do you use ? Rainwater, tap water or RO water ? Kind regards.

Hi Matthew, How much of a splash of the worm juice? Is it similar to the Seasol? I've a worm farm and never thought to use it on the orchids.

pretty sure it's NPK

Hooray. I live in Sydney and my setup is the same as yours. Very pleased I found you. 🇦🇺🇦🇺🫶🫶
