Why you cannot keep bonsai trees indoors

Grow one indoors and one outside. See and watch the differences in their growth patterns.

those i keep on balcony - much smaller, curved, "trunk" twice as thick than indoor about 20 cm height
P1100550.JPG
indoor - straight sticks 45cm - twice more height compared to balcony, no curving
same source of seeds - same fruit , same soil, same organic fertilizer
Gonna try trunk fusion on those tall next year

The ones inside are trying to grow to better light. Those outside are probably putting the energy towards more roots and thicker trunks. Just guessing, but the twisted trunks outside may be the plants are following the light to get the best sun angle daily which gives the trunks movement. Great experiment!

This reminds me of my maybe 6th grade science experiment where we grew bean plants outside, inside under artificial light and in a closet. Similar to your results, the plants that grew in lesser light grew long and spindly trying to reach for better light. The one in a closet grew long and spindly until it spent all the seed’s energy and died.
 
The ones inside are trying to grow to better light.
Punicas poked shelf above them.. there is no above light source and they growing straight up, no fototropism similiar to observed in another plants on same windowsill (facing east)
Those outdoor are on west sided balcony so afternoon - evening sun is available for them

until it spent all the seed’s energy and died.
I hope they survive ;) Need to step up from organic soil and fertilizer tho , my plants started consuming too much, and soil looks depleted. Prob gonna start farming spiderplants in leftover soil cuz they are almost unkillable
But those all are next year projects for this year need to finish coldframe and check if i can overwinter my cherry - 1st time ever
If succesful gonna look for some mallsai or tree on discount and check if can keep alive on balcony before i burn money on tree i cant keep allive

Any tips on how to get the seeds to sprout? I know they like it very warm. Perhaps I leave the pomegranates on too long? I"ve just been propagating them through cuttings. Will you be bringing the stems closer together before bundling them up?
 
I just clean and wash fresh seeds and throw them into trays or pots filled with market level soil then put things into a growboxbox with some other plants
temps are like 25C.
Also have bad habit of putting seeds to occupied pots..
After they sprout and grow a bit to seedlings i pick strongest repot and get rid of weak
I dont mess with wet paper towel and bag anymore, only thing i get this way is some mold :/
Plan for those long pounicas is to dig them up,scratch bark, tie together with foil and scotch, repot to smaller and shallower pot or box (current are damn heavy) and let them grow - should survive ands merge and form some trunk thicker than my lemon in way less time
gonna try also bundle some citrus - next year they will all be in like 1 year age
Found also some seeds i didnt use previous time - wonder if i can geminate them after few months
I dont have mature enough punica to play with cuttings, have some success with lemons tho
 
So I'm new to Bonsai but I am a very experienced Salt water reef tank keeper for many years. We grow very delicate corals in tanks so it can't be impossible to grow trees indoors?? Just need to think outside the box and experiment. 30 years ago no one could really grow acropora coral in tanks and now its very a common practice. I had so much growth I was selling it back to the fish store I started with. Lots of upkeep / probably expensive but very possible I am leaning towards.

I have kept freshwater planted tanks for years and I did dabble with corals for a while.
The biggest difference between corals and most bonsai species is that corals dont need a dormancy period. In fact captive corals do better in a more stable environment. Too many fluctuations and you start to get problems. Trees NEED seasonal changes to live. Too many years with out dormancy and the tree will weaken and die. In addition, inside a building tends to be very dry and can also cause problems with trees. I have kept tropical trees inside over the winter and as long as 18 months but they never do as well as when I can put them outside in the summer.

The amount of supporting equipment that goes along with those capabilities is pretty large. Specialized intense lighting, and complex filtration systems, etc. and some species still refuse to grow very much if at all. To replicate direct sunlight is not easy to do (look to the marijuana growers for leads).

Trees are not coral, air is not water. It is very possible to grow trees inside (using specific species all tropical in origin), but those of temperate origins are not easy to accommodate even with artificial lighting. For instance even with high intensity lighting you will be unable to replicate direct sunlight for alpine species. Coral grows underwater and the light is greatly diminished and filtered out the deeper you go. For instance at three feet, over 50% of sunlight is blocked by seawater. In other words coral doesn't require the light that trees do...Air circulation and humidity levels are also big issues for indoor plants

Agree. When I decided to grow Japanese maples here in central Florida (Zone 9b) I knew it would be a struggle because we may only have a few days a year where the temperatures get down in the 30s. Not near enough time to give them their ideal 2000-2500 hours of winter chill hours (32-45 degrees F) they desire. As you said, they would struggle for a couple of years and then die. I refused to give up on them and decided to do the chill requirement for them. Around the first week of December I defoliated them, give them a good watering and put them all in a garage refrigerator. I check them every two weeks to insure they are not drying out. As the weeks go by you can see the new buds get extremely fat as they sleep for the winter. They come out of the frig the first week of March. After about a week back outside they just explode in new growth and look absolutely beautiful. It’s really hard to keep up with all the pinching because they are growing so fast. It’s a lot of extra work but IMHO it’s well worth it if you’re a Japanese maple nut like I am. Probably the most important thing I learned about growing trees is if you give them what they need they will reward you with awesome growth and vigor. I also had to set up my outside area so that the sun could never directly touch their leaves. Just one little ray of light from our summer sun would fry their leaves. It’s a lot of work, but that’s what I’ve decided to grow so that’s what I have to do.

Wow interesting!! Really like these kind of tests as they will either challenge current theory / practice or fall in line with it!! Would like to hear from more people on this. Anazing thing about mother nature is it will always surprise you with a curved ball.
 
Its just testing things that will work fo me or not.. at the cost of some time, little effort, water and few bags of dirt
Before I waste money on something that i cant keep alive
Trees I actually like are way over my budget, things available or in my budget range throws me away (or just cant fit - like 20$ Dig It Yourself 2 meter tall 10 years old cherry - i cant imagine bringing it on my back to balcony and keep alive so i get 10$ kanzan and gonna learn how to keep it alive ;)
I also need to keep my mind busy
And really want to overcome "stick in a pot" issue as fast as i can
Next year could be interesting for me, earlier this year started quite a lot of seedlings to play with
I suspecti if i have only one tree i would murder it by ovecare or too much abuse
