Year-round
Carolina moonseed is a fast, twining vine up to about 15 feet. The Wildflower Center lists its range as north Florida to Texas, and it fits Fort Worth conditions. It likes part shade and low water once established. Give it a trellis and plan on pruning.
- Part shade in circumneutral soil
- Wet to dry soil tolerated, low water once settled
- Needs a fence or trellis to climb
- Male and female vines are separate, so red berries need a female vine
A vine can sprawl onto neighbors or walkways. Prune to the trellis to keep the front yard tidy.
Fall
Red berries show up September to November on female vines.
- Enjoy the berry clusters
- Prune lightly after fruit
- Fall is a good time to plant
- Cut back only what strays
Winter
The vine dies back considerably each season. Do not worry if it looks bare.
- Cut back dead growth in late winter
- Leave the roots alone
- Skip fertilizer
- Expect regrowth in spring
Spring
Prune and train new growth on a support in spring. Plant new vines now.
- Prune to control size before new growth
- Tie shoots onto the trellis
- Water new plants weekly
- Choose the spot carefully since suckering roots are hard to remove
Summer
Flowers are small and greenish from June to August. Fort Worth heat is fine once roots are in.
- Water deeply during long dry spells
- Trim wandering stems
- Keep the base mulched
- Expect little care after the first year
