Hi all, this is a spinoff of the
Perched Aquifer thread over in Soils.
Nutshell version: There's
water trapped under tight-packed suburban houses (slab-on-grade) that is causing issues. It's not at the surface, but a little ways down. So I'm looking for a list of thirsty plants (ideally with high rates of evapotranspiration) as a solution to passively drain this.
Based on the discussion in the other
thread, here are some things to consider:
Location is central Texas (zone 8b), humid subtropical. Soil is clay on limestone, so alkaline (~8.5).Typical annual temps range from lows in the 20's F in winter to low 100's F in summer.Droughts seem to come around in 5-7 year cycles."Natives" are more likely to be accepted, but I'm for whatever works.These will be planted near-ish structures, so roots need to be friendly in that regard.Since the water isn't right at the surface, plants with taproots will likely work better.All forms of plants are welcome (ground covers to trees), so long as they grow fast and pump water fast.
A few suggestions have been given in the other thread, and I'm hoping to learn more here. Many thanks in advance for all your help!
