Colombian Leaf Litter — Avocado Leaves, 20 Count

A bioactive enclosure without leaf litter is a forest floor without the forest. These avocado leaves are the larger-leaf option in The Bio Dude’s Colombian line — twenty substantial leaves that shelter the cleanup crew, feed the soil and make the whole build look like somewhere an animal actually lives. Like all of The Bio Dude’s Colombian leaf litter, these leaves are pre-boiled, baked and dried, harvested ethically from the Colombian rainforest, and guaranteed free of contaminants.

• Feeds the cleanup crew: decomposing leaf litter is a primary food source for isopods and springtails — the engine of any bioactive enclosure, as our clean-up crew guide explains.
• Tannin-rich: naturally rich in tannins, useful in terrariums and aquariums alike.
• 20 larger leaves per pack: the bigger leaf size covers real ground — good for topping substrate and creating micro-cover for isopods and springtails.
• Doubles as decor: the broad leaf shape reads instantly as naturalistic, softening the transition between hardscape and substrate.
• Safe by preparation: pre-boiled, baked and dried before packaging — ready to place once it arrives.
