v0.31 Talk:Soil

I was under the impression that it was NOT a bug that you couldn't plant on dry underground soil.

ARGH

It's a bug, but Toady would rather focus on more important things than it. It may now be a feature, considering that it's been 11 updates and he hasn't touched it. [PREFSTRING: haunting moos] 11:59, 6 September 2010 (UTC)

Underground plants on dry soil

From what I've observed, underground trees and shrubs will only grow on dry subterranean soil if one of the two following conditions is satisfied: 1. there is an unmined soil wall within a 2 tile radius on the Z-level beneath the tile in question (just like how willow trees will only grow within a 2 tile radius of a river/brook/murky pool tile on the Z-level below); 2. there is a muddy tile within a 2-tile radius on the same Z-level (e.g. right next to your muddy farm plots). I first observed this behavior back in 40d and it still seems to be working this way in 0.31. --Quietust 17:45, 11 September 2010 (UTC)

I've wondered at that. I'll have to check with my current fort. --Kwieland 20:23, 11 September 2010 (UTC)

I have a single Z level that is one level below outside (Z-1). Half of it has plants/trees growing all over it, the other half doesn't! The Z-2 level is uniformly un-mined. There is an aquifer, but it doesn't correlate with the no plants area. It could be that under this area is non-soil, but I don't think so. Also, I've noticed that if I level down some hills outside, sometimes the trees grow back, sometimes they don't. Doesn't matter wether there is soil below or not.--Kwieland 20:19, 10 October 2010 (UTC)

Don't just assume that there is or isn't soil underneath - run reveal (ideally in a savegame copy) and check it directly. --Quietust 04:23, 11 October 2010 (UTC)
