Growing Black-eyed Susan vine is a great way to add fast-growing color to trellises, fences, or containers—especially in warm climates like Tennessee.
Basic Overview
- Type: Tender perennial (grown as an annual in most of the U.S.)
- Growth habit: Climbing vine (6–8 feet or more)
- Flowers: Yellow, orange, white, or peach with a dark center
- Bloom time: Late spring → frost
Sun & Location
- Full sun to part shade (at least 6 hours of sun for best blooms)
- In hot Tennessee summers, a little afternoon shade helps prevent stress
Soil
- Prefers well-draining soil
- Average fertility is fine—too rich = more leaves, fewer flowers
- Mix in compost before planting for steady growth
When to Plant (Tennessee Timing)
- Plant after last frost (usually mid–late April in your area)
- Soil should be warm (at least ~65°F)
Watering
- Keep soil consistently moist but not soggy
- Once established, it tolerates short dry periods
- Container plants will need more frequent watering
Support (Very Important)
This vine needs something to climb:
- Trellis
- Fence
- Obelisk
- Garden netting
Tip: It twines naturally—just guide young vines early.
Pruning & Maintenance
- Pinch tips early to encourage bushier growth
- Trim if it gets too long or leggy
- Deadheading isn’t required but can encourage more blooms
Fertilizing
- Light feeder—use:
- Balanced fertilizer every 3–4 weeks OR
- Compost tea occasionally
- Avoid high nitrogen (causes leafy growth, fewer flowers)
Container Growing (Great Option)
- Use a 12–16 inch pot or larger
- Add a trellis or stake directly in the pot
- Use high-quality potting mix
- Water more often—containers dry out fast in summer
Common Issues
- Aphids / spider mites → spray with water or insecticidal soap
- Yellow leaves → often overwatering or poor drainage
- Few flowers → too much fertilizer or not enough sun
Bonus Tips for Tennessee Gardeners
- Thrives in your warm, humid summers
- May reseed lightly if winters are mild
- Works beautifully with:
- Zinnias
- Cosmos
- Ornamental grasses
