Welcome to the site! I hope you enjoy it here and learn a lot...I know I sure have! As far as Ensetes go.....they are seed grown only and do not pup under normal conditions. I've only heard of one type of ensete pupping (Ensete Ventricosum 'Maurelii'-the Red Abyssinian Banana) and this was NOT under natural growing conditions....it was tricked to multiply by completely chopping off a large plant and mutilating the growth point (
there are pictures in the wiki pages). Musas do pup, some more than others depending on the species, but you will never see Ensetes pup, unless it's a really rare or unnatural occasion. So no worries....you're not doing anything wrong! Best of luck with your plants. If you have questions, just ask!
