Grape (Muscadine)
Carlos Pollination Guide
Carlos is self-fertile — a single tree will produce fruit without a pollination partner.
You don't need a second tree to get fruit from Carlos. It can pollinate itself. That said, having a compatible variety nearby can sometimes improve fruit set and yield through cross-pollination.

About Carlos
Carlos is the bronze muscadine that thrives in the humid Southeast where European grapes fail — disease-resistant, heat-loving, and productive. Perfect for wine, juice, and fresh eating with its distinctive musky-sweet flavor.
Growing Challenges
Not cold-hardy below Zone 7; thick skin and seeds aren't for everyone; needs sturdy trellis for vigorous growth.
Frequently Asked Questions
How close does a pollinator need to be to Carlos?
For reliable pollination, plant the partner variety within 50–100 feet of Carlos. Bees are the primary pollinators and typically work within this range. In practice, a tree in your yard or even a neighbor's nearby tree can work. The closer the trees, the more consistent the fruit set.
Can I grow just one Carlos tree?
Yes! Carlos is self-fertile and will produce fruit as a single tree. You don't need a second tree, though having one nearby can sometimes improve yield.
