Yellow Egg-Like Things in Orchid Soil: Fungus or Eggs?

Tiny yellow egg-like things spreading in orchid bark/soil. Cactus died when present; orchid roots turn black. Asked what they are and how to eliminate.

The expert couldn't ID from description alone—could be spider eggs or fungus (especially if mix stays damp). Advised: unpot, rinse roots thoroughly, repot in fresh orchid mix in clean pot. Bag and discard old mix. Black roots often from broken-down mix; repotting fixes.

Clean Reset

• Unpot, rinse roots.
• Fresh orchid mix, clean pot.
• Discard old mix sealed.
• Damp mix favors fungus.
