What are the little yellow balls or "eggs" on my aquarium plant's roots?

1 min read

Most live plants purchased online or from a local fish store come in a plastic pot stuffed with rock wool. Plant farms often place small, yellow fertilizer balls in the rock wool to help feed the plants' roots. Please remove the fertilizer balls before planting your plant so that they won’t cause a nutrient spike in your aquarium.
