Hi everyone, Im putting together a list of which plants grow well with a greywater system. Greywater usually has a level of salt in the water from soaps used in laundry, shower, or bath sinks, so Im wondering which plants can take a level of salt and which cannot. More specifically, Id like to grow edible perennial plants/trees in Southern California, but any info will be great! What have you had success growing?? Thanks!
Can you grow bananas? Everything which does not mind alkaline soil. The other option you do it with a flexible hose and direct the grey water to different spots in the garden, like that soap residue cannot build up.
Bananas grow well in SoCal yeah and I have grown them with greywater. Other successes I've had are citrus, fig, pomegranate, cherimoya, Zapote, stone fruit.
Avocados are a big problem with greywater, they are very sensitive to salt apparently.
This suggestion isn't edible or tropical, but I guess other people will look at this thread looking for answers since you made such a nice title.
We've had willows growing on our soapy greywater for 20 years and they are doing great. Our greywater is very low-tech. We just run the waste water through a pipe and then into narrow little irrigation channels that run past the trees. There are several parallel channels, so we change it every day or three. Interestingly, there doesn't appear to be any buildup of soap on the surface. Art Ludwig's fabulous book and website on greywater point out that topsoil is aerated and thus is the very best for breaking all that gunk down, much better than buried systems.
Create an Oasis with Greywater, by Art Ludwig is a great source of information.
