Mildly Fast Leaf Decay
by Sourish25
Mildly Fast Leaf Decay shortens the wait for leaves to disappear after a tree is cut, so a felled forest clears in a visible cascade.
What it does
Once the trunk of a tree is broken, the leaves attached to it decay on a timer. This mod sets that timer to 5 ticks, a quarter of a second per leaf step, so the decay wave moves from the trunk outward quickly while staying visible. Vanilla game logic is left in place; only the pace changes, and the leaves still fall and drop items as usual.
Because the mod runs on the server, the work of checking blocks finishes sooner, which the author says reduces lag on busy worlds. The mod is server-side only: players join without installing anything, and the server owner adds it to the Fabric server. It is not open source and is released under All rights reserved. The current build, 1.0.0, targets 1.21.11 only.
Key features
Faster leaf decay
Leaves decay on a 5-tick timer instead of the default delay, so cleared forests disappear within moments.
Cascading visual wave
The decay still spreads from the trunk outward in a rippling wave, keeping the effect visible rather than instant.
Unchanged game logic
Only the timing of leaf decay changes, and the vanilla rules for leaves and drops remain in effect.
Lower server load
Faster checks mean the server finishes leaf updates sooner, leaving more processing time for other tasks.

Use cases
Clearing forests
Players who fell large areas of trees get a cleaner landscape without leftover leaves cluttering the view.
Tree farms
Saplings and apples drop almost immediately after a tree is cut, which speeds up tree farming.
Who it’s for: Server owners who want faster leaf cleanup, and players on servers running the mod who cut many trees and want the leaves cleared sooner.
