@mandajayne nope, I bought some new bulbs lol. I suspect the original ones may not have been correctly labelled as when I repotted them, the bulbs just did not look right. I still have them and maybe one day they will flower and I can ID them
@ausgardentags they are in secondhand mix with perlite and haven't been repotted for like 4 years so I'm sure there's next to no nutrition in there 😉 I think I keep bulb feeding them tho! Doh! I am def going to repot this year, spread them out a bit cause they are all clumped up and maybe try some in the ground to see what happens.
Try dividing them so they get more space to grow. Also, best to feed after flowering but since these haven't flowered just do it vaguely around the time that you think they should flower and a low nitrogen feed is best for crocus bulbs. They have quite long foliage so I suspect they've been growing leaves at the expense of flowers.
