Update_ Freiland Bonsai im Winter indoor halten und vermehren

Hello dear wonder friends and plant lovers It's time for an adventure to my little experiment Because I keep free-roaming plants in my apartment during the winter and feed them through cuttings I have learned a lot in the past five months and can say yes it works It naturally depends on the plant species and the right weather I have a temperature of about 21 degrees a full-spectrum LED lighting system and a relative humidity of about 85 to 90% This is likely equivalent to a moderate socio-topical climate The temperature is determined by the room temperature in here The lighting is active for 16 hours every day and the humidity removes the opening between the two cover plates here From the climatic conditions here the choice of plants that thrive here is evident I do need however a long-term or permanent position I have not yet understood how that is possible The most important factor in my opinion is the relative humidity This is approximately 50% plus or minus 10% in living spaces Why do so many tropical plants thrive here And plants from temperate regions such as firs or birches They will arrive shortly From climate tables on the internet one can obtain the average air humidity for a specific location This is often only between 50 and 60% during the rainy season in the tropics Similarly as in the living areas Ficus Monstera and orchids also feel at home in rooms In many northern parts of Europe America and Asia the average relative humidity is over 80% throughout the year It is too dry for many plant species in living spaces Let's talk about the mistakes I made at the beginning I thought the higher the humidity the better I operated the greenhouses with a relative humidity of 90 to 95 percent during the first weeks Initially it also looked very good The ficus developed aerial roots and the plants and cuttings sprouted fresh green growth After some time came the realization The fresh growth of the ficus trees became glassy and died off Also the juniper cuttings did not look very good It had several reasons One was the constant humidity of over 90% It seems to be too much for the plants along with the repeated spraying of the leaves Another thing I was able to determine was that the growing medium was very important Some of the plants were dry although I assume they still had moisture My tip is to use a mineral substrate with regular watering With the relative humidity now lowered to about 85% I no longer have any problems Each plant has its own characteristics Especially noticeable is the difference between coniferous or evergreen plants and deciduous trees and shrubs With the latter you can already see within a few hours or days that something is wrong and may still be able to react It can take several weeks for waterlogging to become visible in conifers such as the Chinese juniper While the plant is still actively growing the root area and lower stem may already be completely rotten You can quickly check by gently scraping the bark in the lower area with your fingernail When the tree is still alive you can see the bright green campion If the area under the bark is brown there is little hope Then you could check the roots to see if there are any fine white roots present I repotted the dwarf juniper into pure mineral substrate and probably saved it He would not have survived the winter outdoors through frost The second one I only stole into the greenhouse for two weeks The third one stood in the forest all winter for comparison Some other plants with problems unfortunately did not make it Both juniper plants from the greenhouse have been in the unheated conservatory for several weeks and are in excellent health A small fir has grown beautifully in the greenhouse I placed it outside in February to see how the tree would react The new sprout has not survived the frost as expected But the tree will now start anew in the spring to be enjoyed A new Spiraea a type of spire bush has sprouted and seems to be thriving Just like some dwarf cottons Now let's move on to the rooting of cuttings Root formation was partially very successful already from November Under various conditions and growing substrates myrtles different junipers and elms have formed roots There were naturally also some failures Some experiments are still running and if you're interested I can create a video about them in the spring I will gradually acclimate these young plants to outdoor conditions starting in April The growth of moss on the surface in this pot with the cotton aster has particularly interested me I double-checked which soil I used It was a mineral substrate and on the surface I sprinkled a mixture of various organic soils I have some interesting videos prepared for the next few months I hope you visit my channel again Thank you for watching and all the best
