Hey guys, we have moved into a new house and I would like to plant a few palms. I have done a pH test and all around the property it is around 9.5. We live in Western

Australia which is a dry Mediterranean climate. There is no frost here so cold tolerance would not matter. There are lots of palms growing around town but where we are

none of the neighbors have any growing so im guessing it will be a challenge. Any suggestions on which species to try?

 

thanks!

The Caribbean/Florida stuff. The genera of:  Sabal, Thrinax, Coccothrinax, Copernicia, Gaussia, Leucothrinax, Pseudophoenix.   Also: Phoenix, Chamaerops, Livistona  

 

Most of those naturally occur on rocky, sandy, limestone- high pH soil.  Also importantly, they range in areas that expiereince 500-1,500mm of rain a year, but often in soils that have little water retention. Most of the Caribbean islands have that type of soil so they should do well.   Avoid the South American and Asian tropical species that are used to rainforests with rich, acidic, humus soil.

thanks! we get an average of 440mm of rain here so it is pretty dry. The soil is very hydrophobic but I don't mind watering and setting up retic to help the palm. Most species around here are Syagrus, Washingtonia and Dypsis, however they are in areas that have a more loamy soil. We live on a ridge of a dune and it seems like all the other houses have just stuck to keeping native plants that can survive in this soil.

Is your rainy season in the summer or winter?  If it's summer rainy, most of those should be ok with supplemental irrigation.  If you have winter rainy season, then the California people have to help you out !

It only rains in the winter here. I have been reading about people placing palms, pot and all into the ground but im guessing once it breaks free and meets the other 

soil it may end up dying?
