2 wide trees don't grow when next to dispenser.
When 2 wide trees are grown using dispensers nothing happens.
STEPS TO REPRODUCE:
-plant a 2 by 2 tree using spruce saplings.(don't grow it yet)
-place a dispenser next to the saplings pointing towards them and fill it with bonemeal.
-activate the dispenser via redstone clock.
Note that when the player uses bonemea on the saplings, it grows, however it does not when grown with the dispenser.
Please fix this bug, it makes automatic tree farms next to impossible.

I believe this might be the same issue as MC-8187. This was also previously reported as MCPE-34357, but that report was resolved as CR.
Does reposition the dispenser help?

Still affects 1.6.0.1
Have you tried positioning the dispenser so that it's facing another sapling?

If there are blocks placed in any of the red squares pictured here, then the tree won't grow:
Thanks @Mega_Spud. Turns out that was the issue. I completely forgot that 2 by 2 trees were dependent on directions.
