keep in mind that most of the media lawns and shrubs are planted in is about one inch of top soil and the rest is sand.
We are trying to grow lush lawns and landscaped spectacles based on what we had "back home". It is not the same.
You are in essence trying to grow grass on a sand dune.
Nutient contents= zero.
Nutrition retention after applying treatment = zero.
The more rocks and non grass the better. And be sure to be aware of the cold hardiness of many of the tropicals...they look nice but do not survive the periodic cold spells we have in this area.
When mine die off I replace with local vegetation only and only that which can stand to go below 30 degrees for prolonged periods.
So far I have replaced every tropical that we first put in. When it stays in the twenties like it has a few of the past January montns they don't stand a chance. Covering protects from frost....no protection for freezing.
Good luck.
