Your profile is lacking some needed information. You can add an automatic signature and location in your profile set-up.
Good advise from Kathy K. on the subject. Do you have a local Jr. College near by? Some have non-credit programs available. Find work in a good organic nursary to learn all the plants and care for same.
I've seen some computer programs where you can make landscape layouts, used by many landscapers.
Remember, landscapeing is more than plants, it also includes walkway materials and such.
Many large Landscape Co's have maintenance crews the take care of the really nice yards that have been designed for the owner. From there you can make good observations.
Good luck on your new indever. Stay in touch and let us know now things are working for you.
