Do I need more than one vine for fruit?

Many varieties are self fertile, but female varieties such as Scuppernong need a self fertile vine planted nearby to set fruit, so check your variety before planting a single vine.

Prune heavily in late winter while the vine is dormant to encourage new growth.

Growing it

Propagation: cuttings, layering, seed
When to plant: spring, fall
Overwintering: Prune back excess growth in late winter before new buds appear. Ensure the base is mulched to protect roots from extreme temperature fluctuations.
In containers: Not ideal for containers due to its massive size and deep root system.

Hardwood cuttings

Take cuttings in late winter from dormant wood.
Ensure each cutting has at least three nodes.
Plant in moist, well draining soil until rooted.

Planting aromatic herbs near the base of the vine can help mask the scent from potential pests.

Grows well with

Basil · It helps deter certain pests and thrives in similar sun conditions.
