Moss and Bonsai Tree Health | Moss does THAT to your bonsai?

[@TheBonsaiZone]

Moss for thought! I personally love it, as long as you keep it trimmed in height and you keep it away from the trunk, all is good. I find you can read the moss, just like the surface of soil to tell if your tree needs water. It certainly helps keep the soil a more consistent level of dampness from the top to the bottom, especially on hot dry days. Have a great holiday season Dave!!!

[@BlueSkyBonsai]

Thanks Nigel! I would love moss a lot more if there were no birds in the area here.. And yes keeping it away from the trunk is an almost daily task... there's always one that creeps up on you! But yes it's worth the hastle, on balance. Have a great Christmas holiday too!

[@janbowles2449]

[@baldyeti]

I dig it when you bring out the white board. I pause it, prepare myself to focus, give a little “here-we-go”, and press play again. Great info on moss, Dave. I like to let it grow on the outside edges of the pot and let it creep towards the tree, then rip it back. The mounding type, I am playing with shaping into “bushes” (mimicking Nigel’s forests).

[@BlueSkyBonsai]

Thanks Billy, really appreciate your comments! The whiteboard is always fun to do.. but of course takes five times longer than the rest of the film... Yes you can do some fun scenes with moss, I just wish the blackbirds were allergic to it. Merry Christmas!

[@BlueSkyBonsai]

Thanks Dave I really appreciate your visit and kind comment. It's a funny old thing moss, some people have a hard time controlling it and removing it from their trees, while others have a challenge keeping it alive. Maybe I should try selling the big tufts that I take off, still attached to some of the bonsai soil beneath... like turf rolls of grass for gardens! on the other hand it would be almost impossible to import in US and Canada due to the tight regulations on importing plant material.

[@BlueSkyBonsai]

Thanks! I really appreciate your great feedback. The pergola project, I started it half-hearted last year in May, by erecting a post with a cross-bar at one end of the benches. That holds the shade sheet in summer which was the main purpose of the pergola design (aside from wanting ot to look nice!)

[@AlwynFisher]

I like moss on a bonsai, I think it doubles up aesthetically as grass from where it grows. However, I find it grows differently in each pot. I have a small horse chestnut and last years moss was the lushest ever, however in a larger, shallower pot I couldn't get it to grow at all. Either way, after watching this video I'll be taking it off all my trees and letting it start to grow again in March.

[@BlueSkyBonsai]

Yes also here, it's definitely not the same in each pot. Some seem to favour moss more than others. My largest shallow pot has a ginkgo forest in it and that is seriously overrun with moss this winter. But several other shallow pots seem not to have adopted moss this year. Same with deeper - some have it and others don't. Ultimately I remove the moss on spring so I can see the soil surface in summer, and because it I know it'll come back by autumn anyway.

[@joelhiggins6156]

I wish I had the problem of too much moss! Here in the Central Valley of CA its just too hot and dry in the summer. I suppose full shade and lots of misting may help

[@BlueSkyBonsai]

Hi Joel, yes in summer I use a 50% shade over my benches, and automatic watering during the day so the moss never dries out in the hot daytime temperatures. Otherwise, like you I doubt the moss would survive. Here in Madrid in summer it usually goes above 40°C in the hot afternoons. Also, the benches are on the East side of the house so in later afternoon they are shaded.

[@dbchannel9882]

Wonderful video David, thanks for sharing your knowledge! I’m just struggling to understand how I’m supposed to know when to water the soil underneath the moss. I believe only misting the moss won’t be enough for the bonsai?

[@BlueSkyBonsai]

Thanks! Great question. I sometimes mist the moss so that it will freely absorb water from the watering can. But just misting the moss won't give your tree's roots enough fresh oxygenated water. When we water a bonsai we need to ensure some water drains freely out of the holes under the pot. As gravity pulls down the water table in the pot, it'll also suck in some air at the surface, which is essential for the healthiest roots. Do you have granular soil under the moss? If so, you can water frequently and make sure the water runs freely out the bottom. But if you have garden/peat type soil, the roots might slowly get starved if oxygen, and like you've said with moss on top it's impossible to see of that's happening.

[@dbchannel9882]

@@BlueSkyBonsai thanks so much for the quick reply and detailed explanation 🙌🏻 I do have the organic soil type, so I think I’ll keep misting the moss frequently while making sure to water the roots too sometimes (until I see the water drain down the pot holes, like you have said). Maybe by using a moisture meter it would be easier to just stick it in the soil and see if the underlying soil needs some water.

[@BlueSkyBonsai]

@@dbchannel9882 yes a water meter will tell you, alternatively sticking a chopstick down into the soil and then inspecting it will be a simple way of checking the moisture. Just remember that 95% of bonsai deaths occur because of drought / forgetting to water; whereas a very small percentage die of rotten roots due to waterlogged stagnating water. So.. if in doubt, err on the side of watering more!

what do you think of moss substitutes like sedum? I was leaning to Cape Blanco or a type of Sedum Dasyphylllum. These grow to 2in height

[@BlueSkyBonsai]

I like sedums but personally I wouldn't put them in a pot with my bonsai because they might end up needing more attention than the tree. For soil coverings it's best not to use plants that root into the soil, so that the roots aren't competing for space with your tree's roots. Maybe in a forest scene or penjing it could be a great addition.

I use moss on my bonsais because it's so great looking and keep humidity. once you are aware of the risk for your trunk it's ok. BUT, since i live in an appartment with a lil blacony, i cant get any rain water. And if i use classic kitchen water, the moss turn brown and die. I could use distilled water but since you need to keep it alwait moist, it would cost more than a bonsai per month :D Any ideas ? ( forgive my english it's not my born language )

[@BlueSkyBonsai]

Your English is perfectly good enough! The water, could contain too much chlorine or flouride (depending on your country's water rules), in which case let it stand in a bucket for a couple of days so those chemicals evaporate off. But if the problem is alkaline water you can get some mild acidifier tablets. Even a tiny amount of aspirin would lower the pH. Or, if the problem is calcium carbonate in the water, which gives you limescale everywhere, you could use one of these to filter the water before you water your bonsai: www.amazon.es/AmazonBasics-Jarra-filtrado-agua-Negro/dp/B01GFJWA52/ Hope that helps.

[@zzredragon]

thanks for the help , i do wait a couple of days when i fill bottle, so that some of chemicals ( chlore ) can evaporate, so that's not the problem i guess. i think it's calcium carbonate indeed. thanks for you answer and your tip, i'll try it and tell you about. in the meantime i collected new moss (small moss, i used sphagnum moss wich is kinda big and ugly ).

[@BlueSkyBonsai]

Keep the moss humid and don't leave it in direct sunlight for a few weeks. That could mean putting some cling film / plastic wrap over the soil every day after watering, because your tree's leaves do need direct sunlight. But ultimately don't worry about it, yellow moss is still healthy and absorbent, even if it doesn't look as nice. In the long term it will green up.

While I've got you if you don't mind 2 questions In Melbourne here it gets very hot at times, it's 33c tomorrow and 37c Tuesday and concerning my Chinese Elm and Trident maple. The Elm is doing fantastic beautiful dark green leaves and now 5-6 cm of new growth on the 2nd flush but the original dark green leaves are starting to drop of, so interesting. Similar thing with the Maple, doing very well and then the tips of the leaves started turning brown, has gradually overtaken the whole leaf on some and they to are falling off. Bit different as the Elm leaves didn't turn brown but both frustrating. Any thoughts? One of my contacts here thought the Maple was lack of nitrogen but I'm not so sure. Do both trees have a temperature tolerance do you think and maybe just too hot and need to be brought inside if temperatures get above say 26c as an example or is it under or over watering. They are both in an open mix so I would think over watering is not the issue but then I give them enough water in my opinion so I don't know, the Maple is putting on its 2nd flush so the tree can't be that unhappy but I'm nearly at my wits end as to what's going on and that's the main reason for taking the sphag moss off so I can actually view the soil and moisture level. Any imput would be greatly appreciated. Cheers Glenn

[@BlueSkyBonsai]

Hi Glenn, I have a similar situation every summer here in Madrid. It sounds like your soil drainage is good enough so you're definitely not overwatering. In fact in summer you could water more times a day - e.g. you might consider installing an automatic watering system. Many years ago I remember seeing advice that we should only water when we see the soil is dry, and one year I lost a few trees by following that advice. It was simply bad advice for hot climates and good draining soil. So now every summer I set the watering for 3 times a day, - it never rains here in summer, and I increase to 4 times a day on really hot days above 36°. Even so, some bonsai like trident and japanese maples still get burnt leaves in the hot sun, - they are really not evolved for such strong direct sunlight in temperatures above 36 or so. Therefore in summer I keep a 50% shade cloth over my bonsai benches, right from 1st June to 30th Sept. For you would be from beginning of December through to end-March. As long as all your trees get some sunlight every day, they will fare much better if they don't have like 8+ hours of full-on direct sun all day. And never let the soil dry throughout the growing season. Hope that helps! Dave

[@glennmcfadgen4137]

Thankyou David I will work on more water and protection on the really hot days. Love your informative and detailed videos by the way they are extremely helpful, thanks again Glenn

[@SysterYster]

Dave, I was given a small juniper right before Christmas. What should I do with it? They always die for me. Do they need a lot of water, or little? Do they need to be out in the cold or not? I'm unsure if it's good idea to put it out on the balcony when it's so cold. But maybe it should be in the cellar? Or should it just stay indoors since it's a Christmas juniper (I don't know what kind it is, but maybe it's some "indoor" type)? Halp?

[@BlueSkyBonsai]

Junipers are definitely outdoor trees, all year. What kind of pot and soil is it in? If it's indoors in the warmth at the moment, you might need to get it gradually accustomed to the cold, first day a couple of hours outside at the least cold time of day, then each day extending the time out in the cold. If you're worried about the roots freezing you could wrap up the pot in a few layers of bubble wrap while it's outside. They need enough water to keep the soil moist but should not sit in waterlogged soil. Don't water before putting it outside because the additional water in the pot could freeze and crack the pot (depending on the shape and size and material of pot). And only water it when it needs it, with fridge-cold water until spring, so the roots get the message that it's winter now! But I'm also curious, when junipers died for you in the past, were they indoors in winter? Or where were they when they died?

[@SysterYster]

@@BlueSkyBonsai Alright, thank you. I thought so. ^^; Eeehh... I haven't dug it up to check. So just a normal flower pot and soil (I assume) with moss on the top. I can put it in the cellar with the other trees then, I suppose. For training. It's around 6-10'C down there. Right now it's -10'C outside. :P Too cold to practice in. Yeah, they were indoors. But I rather like them, so I thought I should attempt to keep this one alive. XD

[@BlueSkyBonsai]

@@SysterYster the thing is, junipers need some light on winter days too, unlike deciduous trees . Will it get light in the cellar?

[@SysterYster]

@@BlueSkyBonsai There are two tiny windows high up. So, a little, but not a ton. Is that enough? Or is it better I put it on the balcony for just short times and get it used to it slowly? It's a little warmer today.

[@BlueSkyBonsai]

@@SysterYster what's the temperature on the balcony? Personally I would get it accustomed to the cold, day by day, so that the foliage continues to receive enough light. On the other hand, if the balcony temperature drops to colder than -10° then yes maybe it's better in the cellar for a short period of time. But it's not like a deciduous tree that can go for three months with very little light in winter - junipers need light during winter too. Because of their small scale foliage they need as much sunlight as possible all year round.

[@BlueSkyBonsai]

If you like the look of the moss, keep it on the soil. What's the climate where you live? Azaleas usually survive better outdoors, unless it's too hot and dry. Azaleas need light, so indoors it needs to be in a bright window but not above a radiator. Also, don't let the soil dry out. it won't survive like other houseplants. Also don't let it stand in a pool of stagnating water. It's fine to keep the moss, but don't forget to water it!

[@BlueSkyBonsai]

It's a good point, if the whole soil surface is covered with moss saturated in water there's a good chance the soil isn't receiving enough oxygenated water maybe the key is to over-water in that case, to be sure the water is sucking down some oxygen and expelling the older depleted water. But ultimately, as you rightly said, it's just easier to avoid moss completely so you don't get these problems... Cheers and happy new year!

Thoughts on moss. Long have I attempted to cultivate massive sheets of the precious material. Legends say ancient humans or perhaps santa claus insulated his boots with moss. But for a surface dressing, its hard to beat sifted crushed granite. It has a good look of sharp sand.

[@BlueSkyBonsai]

Sounds like you have developed a system that works well for you. For my top dressing I like to use materials that significantly change in tone or color when they're wet, so that it's easy to see at a quick glance if they need watering. Course that becomes irrelevant when it's covered in moss...

[@Tarnishedgrimm]

do you know any methods on how to clean out moss and prevent insects from hiding inside. I’ve used moss for one of my trees and millipedes took over! pesky things.

[@BlueSkyBonsai]

I occasionally spray the top surface of the moss with a mild plant-friendly water-soluble insecticide. Not an oil based insecticide, because you want the stuff to wash through the moss next time you water. If you're concerned about the effect of your spray on the moss you could try it on a small corner first? Also, if you use chunks of moss lifted from nature, it's probably already got the insect eggs or lavae in it when you place it on your bonsai soil. To avoid that, you could just trim the top of the moss and sprinkle that on your soil - it grows directly from the trimmings as long as there's enough humidity. It'll take longer to look lush, but it should be insect-free.

i like moss, but here in adelaide australia moss is impossible to keep except for 2-3 months a year

[@BlueSkyBonsai]

Is the Adeleide sun too strong for the moss? Or is it the hot dry air? A few years ago I installed a misting system in the heat of summer and the moss grew vigorously then.. worth considering?

I think I heard Ryan Neil say that moss also filters the water and reduces the lime content.

[@BlueSkyBonsai]

That sounds like a very good benefit in hard-water areas. I must do a test of that, I can easily test the calcium carbonate concentration before and after passing water through a mat of moss. Thanks!!

[@murray821]

@@BlueSkyBonsai I don’t know if it filters it directly or that the moss uses the lime or balances the acidic content. Can’t find the video at the moment where he talked about it.

[@BlueSkyBonsai]

@@murray821 sounds right, because calcium carbonate makes water slightly alkaline and most trees prefer something between neutral and quite acidic. I definitely use rain water on the acid-loving plants like azalea and camelia.. except in the summer here there is no rainwater so I have to use our tap water and those plants don't seem to suffer in summer. Probably the soil acidity is more important. And moss is slightly acidic.

[@radrickdavis]

Moss always returns in my rainy climate, even when using fresh new soil. So I learn to live with it. Just like a lawn it needs to be mowed down and edged when it becomes overgrown, or the tree bark will become overly shaded and perpetually damp. It is really difficult to fully clean and sanitize soil covered in moss. I usually recycle my soil by leaving it to dry in a covered bucket, and then the organic material becomes like shaff that blows off in the wind. Let me know if anyone has a better method for eliminating moss without ruining the soil.

[@BlueSkyBonsai]

Yep, I hear you. The only way I can sanitize the soil is by scraping off all the moss radially away from the trunk, then adding a layer of fresh topsoil, fine granuals. It's once a year, any more frequent would be too much work for so many trees.

[@RJSRanchu]

Does the moss take nutrients from fertilisers instead of going to the tree ?

[@BlueSkyBonsai]

I think the moss takes a share of the fertiliser, yes, but in proportion to the overall soil. I don't believe it deprives the tree of nutrients by filtering them out of the water. I have moss on some trees and not on others, and I observe the same vigorous growth on all the trees with or without moss - I fertilise them all the same way with liquid fert diluted in the water. If the moss were depriving the roots of nutrients we would see less vigorous growth on the trees with moss. Does that answer your question?

[@SysterYster]

I love the way it looks with moss. But I think I will wait to attempt any of that until my trees are older. :P But at least they're alive and well still. I think. I mean, the tropical ones are indoors and growing, and the others are sleeping on the balcony or in the cellar depending on how cold it is. :) Except for one tiny maple, I was gonna toss it out, but I figured if it survives the entire winter on the balcony, it gets to live. XD

[@BlueSkyBonsai]

Hi Syster! The good thing about having quite a number of trees is that you can make this decision for the maple without it being a big deal if it makes it through winter or not. I hope it might survive, since I guess it still had leaves as normal until autumn. Moss is just great as long as you don't have foraging birds nearby. Also less of a problem if you only use chemical fertiliser... organic ferts are like a red flag to a bull!!

[@SysterYster]

@@BlueSkyBonsai It was a fine little maple, doing well and all that. :) But it wasn't red as I had hoped. And I already have two green ones. No big risk of birds at the glassed-in balcony. :P Though it certainly can happen when it's open in the summer. But I've never seen one in there. I use chemical ones. Usually the kind you mix in the water directly.

In my place its so dry, that my moss dies In short time...

[@BlueSkyBonsai]

It gets very dry here too for about 5 months each year but then gets wet over autumn and winter. If you really wanted to develop moss on your soil you could try keeping cling-film over the soil all the time exceptwhen you're watering. That would keep the humidity, and let the moss grow.on the other hand it spoils the nice look of moss if you always have it covered...

[@zicada7661]

I think all mosses you find growing naturally have antifungal properties. Why buy spaghnum moss ?

[@BlueSkyBonsai]

It's true, a few years ago I used spongy moss that I picked off my lawn, and used it successfully in an air layer. flic.kr/p/24oH3VF It worked well but at the end of the process some of the longer overgrown roots had started to rot. flic.kr/p/2gnCwQM It might have been exactly the same with sphagnum, so I can't rationally blame the spongy moss for the rot. Ultimately, a bag of spagnum is quite cheap, and very convenient when you need it.

Moss don't grow on my bonsia trees yet

[@BlueSkyBonsai]

Do you want moss? If you do, you can cultivate it from moss you find in nature on the sidewalk for example. But as you saw in this video, it's probably easier on your bonsai workload to just not have moss on them. And .. binge-watching my vids is a good thing! Anything you can see I'm doing repeatedly wrong or missing in each video? I know the music was too loud in the earlier videos - got that.

[@chasingthefish9042]

@Blue Sky Bonsai your videos are always great. I do have moss I don't think my trees are full enough or big enough to provide the shade for moss. All my trees are 6 months old other then my portulacaria afra and junipers. most of the ports are cuttings from last summer. My junipers are kinda not great I got them on sale and they looked sickly. I have 4 jpb 2 Brazilian rain trees 4 flame trees 4 crepe myrtle 1 siberian oak 2 junipers

[@BlueSkyBonsai]

@@chasingthefish9042 that's a good collection. My advice (unsolicited, apologies) for the junipers is to just let them grow back to health then leave them for at least 2 years, maybe more, to grow strong and vigorous. If you try to work with weak junis they don't respond well ...

I'm struggling to keep any moss alive, let alone propagating it 🥲

[@BlueSkyBonsai]

Sorry to hear it. Well looking on the bright side, at least you're avoiding all the insect larvae and bird attacks!! If you're really keen on getting the moss thriving, you could try putting some in a sealed clear plastic bag with some moisture for a couple of months, leave it in the light but not direct sunlight. It's usually dry air that defeats the moss so keeping it humid is the key. Good luck!

[@katyb2793]

@@BlueSkyBonsai oh that's a great tip! Thank you! We've had a very cool summer here in Australia, and it's not that humid so i suspected the humidity may be a problem. I've been sprouting flower seeds in containers on the windowsill, but why did I not think of doing something similar with the moss? Lol! Other Aussies near me manage to grow moss easily, so I'm hoping once I get it on my bonsai it should be OK. Will have another go. Thank you so much!

[@katyb2793]

And yes and amen to less insects. It's been a real learning curve with our cool summers the last 3 years! I can't imagine if they had moss to live in.. maybe I should rethink this 🤔

[@BlueSkyBonsai]

@@katyb2793 in general the insects are ok if you only use chemical fertiliser. When you use organic ferts like BioGold, which is basically high quality chicken poop, you get insects laying their eggs in it, then a few weeks later the larvae are in the soil and moss... that's when the birds attack. Actually when it's cooler seems to be less of a problem, maybe worse in the hot weather.

[@katyb2793]

@@BlueSkyBonsai oh that's so interesting. I use a slow release fertiliser which I assume is chemical. The insects I have without moss are mainly aphids, spider mites, scale, caterpillars, loopers I think they were called, mealy bug (I think) and a couple of others going after my veggies. They usually get fried in our 40 degree Celsius days so when the weather is averaging low 20s they multiply like crazy and are a bit difficult to manage. We've had a La Nina the last 3 years, so hopefully next summer will be back to normal! Then I'll be spending all my time watering and melting 😅
