Leaf size: approximately 1 inches.

Utricularia olivacea requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Olive Bladderwort thrives in bright indirect light. Avoid placing Olive Bladderwort in direct, harsh sunlight for extended periods, as this can scorch the foliage.
