[MC-8187] Two-by-two arrangements of jungle or spruce saplings cannot grow when there are adjacent blocks located north or west of the sapling formation

The Bug:

Two-by-two arrangements of jungle or spruce saplings cannot grow when surrounded by any block other than a sapling that's located to the north and/or west side of the sapling formation.

This can be anything from a torch to a snow layer, to a grass block. The south and east sides do not have this blocking effect.

Steps to Reproduce:

Build the setup as shown in the attachment below.

[media]

Apply large amounts of bone meal to the said saplings.
Take note as to whether or not two-by-two arrangements of jungle or spruce saplings cannot grow when there are adjacent blocks located north or west of the sapling formation.

Observed Behavior:

The saplings will never grow into trees naturally or when bone mealed.

Expected Behavior:

The saplings would grow into trees and not be prevented by adjacent blocks located north or west of the sapling formation.

Unable to reproduce. Are you sure you give them enough space to grow?

Mustek 2013-01-24T16:54:29Z

Unable to reproduce either. If it still occurs, take screenshots and create a new ticket with them.

Maarten Thijs 2013-01-24T18:45:48Z

glad you guys gave me 4 hours to respond...
anyway I found the issue, please reopen

Tails 2013-01-24T19:03:33Z

There may not be any blocks adjacent to the north-western sapling, as this is considered as the center of the tree. More information can be found here..

Maarten Thijs 2013-01-24T19:11:51Z

okay so why does this work with just a single sappling?

Because a single sapling center block isn't on the north-western side.

Why exactly is this marked WAI? I don't see any devs explicitly confirming that this is intended.
Also, if we assume WAI, why doesn't dark oak have this restriction?

Rodrigo Cardoso 2017-03-30T21:48:39Z

My report about they not being able to grow next to carpets has been marked as a duplication of this, and there's no relation considering this started to happen only in recent versions.
I don't see how this can be marked as intended either, considering dark oak trees and 1x1 trees of all kinds grow with no problem.

Michael 2020-07-31T23:01:26Z

It can not even handle if you have a grid of saplings (like say 8x8) or 2x2 tree to close (less an 6 block apart).

This in 1.16.1 singelplayer, newgen world

Hi! I'd like to request ownership of this report.

clove 2020-09-07T18:59:38Z

Can confirm for 1.16.3rc1

Can confirm in 20w48a.

Can confirm in 21w05b.

Faye N 2021-07-13T04:43:47Z

Still an issue in 1.17.1. I'd like to add that single-sapling trees of any kind will grow just fine in snow-covered places, it's just 2x2 spruce and jungle trees that can't. 2x2 dark oak does work, however.

ampolive 2021-09-23T19:49:22Z

Can confirm in 21w38a.

Avoma 2021-10-03T10:06:08Z

Can confirm this in 21w39a. Here are some extra details regarding this problem.

The Bug:

2x2 arrangements of jungle or spruce saplings cannot grow into trees if surrounded by snow.

Steps to Reproduce:

Build the setup as shown in the attachment below.

[media]

Apply large amounts of bone meal to either the spruce or jungle saplings.

Observed Behavior:

2x2 arrangements of jungle or spruce saplings cannot grow into trees if surrounded by snow.

Expected Behavior:

2x2 arrangements of jungle or spruce saplings would be able to grow into trees even when surrounded by snow.

It's probably worth noting that this extends to basically any block occupying the same space, including ones which are completely transparent like grass or ferns. I suspect this is probably to keep the giant spruce trees with leaves on the bottom level from intersecting any blocks, but spruce saplings are ignored in that check anyway so I don't see why that couldn't be extended to include other blocks.

Jack McKalling 2022-06-28T17:22:01Z

I also noticed that adjacent blocks are only blocking tree growth from the north and west side of the sapling formation, but not the east or south. So it doesn't have to be fully surrounded. It also doesn't matter which sapling gets applied the bone meal, all saplings in the 2x2 formation behave as if they were one single sapling with 12 adjacent sides instead of 8.

Avoma 2022-06-28T17:28:52Z

@unknown, I believe that issue is MC-118980.
