Everyone must stop thinking that potting soil is good soil. Its one of the worst soils that exist. Potting soil is thick and dark and only holds onto moisture for way too long. That is a very good way to rot the ginger away and never have any growth. Gingers and heliconias perfer a well draining soil and definately do not want to be kept wet. Moist is good, but never drenched in thick wet soil. Add perlite or coarse sand to a "potting mix" or "potting mixture"
NEVER USE POTTING SOIL. Potting soil is thick, dark, heavy soil that holds on to moisture too long and rots away most things that you plant within it. You never want to start anything out in potting soil. Some things will still grow when planted in potting soil because they may have that much strength established at the time of transplant, but never start anything out that is young or small in that type soil. Potting mix is a better soil, and also mixed with sand or perlite allows for even better drainage.
Both species of Washingtonia, filifera and robusta, are very common palms in the southwest. Washingtonia filifera does not spread as far north as Washingtonia robusta. This palm can be found in southern California and in the inland deserts of southern California.
Kerosine will also do just as well as killing the plant, but you also render the land and soil useless and dead for many many years after the kerosine or diesel has been soaked in.
It is difficult to tell from the pictures that you show, as they are not up close to the leaves, but date palms are famous for having spider mites. It would be no suprise that your date palms are suffering from exactly that. For some plants, it may be easier to control spider mites. But for something such as date palms whos trunks hold so many crevices and gaps, it would be almost impossible to get rid of the spider mites if that is in fact what you have. In nature, these spider mites are subject to the elements. Nature can control these bugs. But when indoors, spider mites are free to thrive and grow exponentially.
