Today I wanted to change the soil in my Alocasia plant, but I found these things in the soil, around the roots. They weren't attachments, they where just laying in the soil. I bought in in an IKEA store. Does any of you know what this is?
Alocasias have bulbs and can be grown from bulbs, How to grow an Alocasia from a bulb. So what you have found in the pot are unsprouted Alocasia bulbs.
These plants often could go dormant, loosing all of their leaves and becoming a stump just to regrow from the bulb next spring.
