Thank you very much all of you for your replies!
Very useful and interesting information! Your experiences are great and i thank you very much for sharing them with me!
The banana i am talking about,i dug it out from the ground and moved it to Pyrgos so it wasnt potted. I chose the planting depth as i got it as a pup. I stuck to shallow planting in fear of rot from our winter rains during its original planting. After digging it out and moving it to Pyrgos, i just made a depression on the ground to accommodate the rhizome and set the rest of the shallow root(pan) i had taken with it,just rest on top of the ground,and made a little mound of soil around them. Thats how its currently growing in Pyrgos. Do you think it will find its own correct planting depth as it pups or should i dig it out again and plant deeper? It surely has rooted well again as its been growing fast since last fall,just a month after moving it!!! I would certainly prefer not to disturb it if it can find its correct planting depth by itself.
I would think that as a rhizome growing plant,it should have mechanisms to allow it to pup at the depth it considers the most suitable for the pups's better growth. I do have heard about mats going shallow with time and toppling easier but from what i have seen,the soil these mats are growing on has become yucky,muck,boggy,bad for the root health and thus the plant decides to go shallower in search of better root conditions. So,in this case,its the bad soil that causes this and not a wrong response from the plant. Correcting the soil or not letting the soil degrade that much would allow the mat to choose to grow deeper and better. I would think that bananas would select correctly their growing depth as banana mats have proven to survive for many decades in unmanaged plots of mixed vegetation with no need for replanting or management of any short.
What is your opinion?
Thank you very much in advance!
