Welcome!
That sounds like a wonderful undertaking!
Make sure you setup a very good irrigation system for your plants, use a good substrate for planting, and keep a lot of compost on hand and teach your customers about composting kitchen scraps and other compostable items from around the home such as paper towels and napkins.
I also urge you to tag every plant that leaves the nursery, check them at the door to make sure they are tagged.
And please encourage them to join the IBS!
Please keep us updated with the progress!!
