12 with a planting plan Clearly in mind i.e. no rocks, mulch, or jute where the customer wants Grass!!

13 BUT wait a minute why would anyone choose GRASS??? some do, some don t so be sure you know!!

14 Either way, you can expect plants to be the star of the show and trees to be the headliner!

15 TREES The Backbone of every Natural Systems Project, & every Planting Plan Why plant just one When there is plenty of room for Three!!

17 WELL, NO. there s a little more to it.
