Do I need a partial shade plant if an area gets 4 hours of sun in June & July and then falls back to 2 hours of sun in August on into late summer September? Thank you!!!
No, unless it’s getting to hot.
I would say yes, you would need partial sun/shade plants for 2-4 hours of sun. Most partial sun plants need at least 6 hours. The C&G units provide light for 16 hours for that reason.
Agreed with @Seaserpent
