Hello, I have 2 of the "Ice Cream" variety of bananas and 2 of the "Dwarf Cavendish" variety in large pots on my deck, they receive full sunlight throughout the day. The two "Ice Cream" variety look very healthy and are producing larger leaves with every new bunch however the plants are not growing tall at all, I've had them since early April and really have not much to show for it. This variety is supposed to get very large but I can't seem to get them to grow tall. My "Dwarf Cavendish" variety are putting out larger leaves with every new batch as well but again they aren't getting tall. I checked the soil and it is moist but not super wet. I will say that at night temperatures are in the high 40's to high 50's, I know that wont kill them but is that the reason for their slow growth rate? What temperature do bananas just flat out stop growing?
