I only grow the Dwarf Eucomis 'Tiny Piny Opal'
They grow in that little fabric container. During late Spring to early Summer they are out in full sun, and I start watering actively when I see new leaves sprouting. Then got to water them often to daily, especially when our temps are hitting 90F and higher to triple digits. It always makes it blooms during our hottest period in August. By late Fall, it will die down and will just hide in my garage till next Spring. I have not repotted this either since I got it, knowing that it prefers to grow tight. Oh, and I did add a little compost during Spring.
Maybe you need to adjust watering?
