Fern — Minecraft block

Overview

Fern counts as a plant block in Minecraft 1.21.4. A hardness of 0 means it is one of the quicker blocks to clear. No specific tool is required to collect it.

Light passes through it, so it will not darken the space behind it. It offers almost no protection from explosions (0 blast resistance). A full stack holds 64.

It is not used in any crafting recipe.

How long it takes to break

Fern has a hardness of 0. By hand that is 0 seconds per block; with the correct tool at netherite tier it is 0 seconds.

Nothing here needs a minimum tier: whatever you swing, the block still drops, and the only difference is how long it takes.

Efficiency adds its level squared plus one to the tool speed. On a block this soft the enchantment reaches instant mining almost immediately.

Properties

Fern resists blasts at 0, which is not enough to survive anything explosive nearby. Light passes through it, and it emits none of its own. A single slot takes 64, the usual full stack. Fire spreads to it readily (encouragement 60, burn 100), so keep it away from lava and away from anything you would rather not lose. An axe is the fastest choice here. A tool of the wrong class is no better than your fist — the speed bonus is tied to the block's own tool tag.
