I have a bromeliad which has had some problems. The central flower got infected (fungus, I think) and fell off but the green leaves are doing ok. The central stalk (flowerless) still appears to have some fungus. I purchased some fungicide today. I also decided to replant it since I have not done this since purchase. In the current soil, there are small yellow balls which have white goo inside. Are these supposed to be there? Belong to the plant or related to the fungus? Any help?

Thanks
