We've been out for the evening folk - just got to reading this now.
In IG Pro, Gardens= Gardeners, Trevor. You'll see the examples in the Master Database.
Its really how you interpret the description.
Be aware that the plants and photos in a database are shared.
You can add the same plant to any garden, of course, as many times as you like.
You can use the Title and description for Photos to identify in which Garden/Gardener they were taken.
You can also create a separate database for each Garden/Gardener
However, in that case, you have to maintain the plant list and information independently.
For that reason, I prefer to keep all Gardeners in one database.
