I want to build a tree farm. But now I do not want to sit down every seedling by hand.

How exactly can I do that, or can I even do that, the seedling over Redstoneitems down there? The whole thing is supposed to run in the 1.8

Dispenser u. Droppers from different positions do not work.

This is not possible in Vanilla Minecraft.

It does not work without mods.
Maybe over a CommandBlock with set command, otherwise I see no possibility.

Okay thank you. I already thought so.

Okay thank you.

Is there then a possibility that somehow one asks whether a seedling stands on a block? Because the things do not lead a signal and observers are not yet.

Ma

I would not know that.
