How Do I Care for a Vining Black-Eyed Susan Plant?
The vining black-eyed Susan (Thunbergia alata) is a cheery addition to the garden. Blooming in red, yellow, orange or white flowers, on vines that can reach 6 to 8 feet in length, vining black-eyed Susan looks stunning trailing over a hanging basket. This vine loves to climb, so if it is planted in the ground, provide it with a sturdy structure. Vining black-eyed Susan is a perennial in U.S. Department of Agriculture hardiness zones 9a to 10b. In colder climates it is grown as an annual.
things you’ll need:
- Composted pine bark
- Rotted manure
- 12-6-6 fertilizer
- Grow the vining black-eyed Susan in full sun. Although the plant will tolerate partial shade, it will not flower as profusely as it will in full sun.
- Provide the vine with fluffy soil. If you are just planting your vine, add 4 inches of composted pine bark and rotted manure to the soil and mix it into the top 10 inches.
- Water the vining black-eyed Susan to keep the soil moist, but not soggy.
- Fertilize the vine with 12-6-6 fertilizer every four weeks. Dilute the fertilizer to half the rate recommended on the package and apply it to wet soil.
- Check the black-eyed Susan vine periodically for signs of spider mites. Evidence of this common pest includes bronze-colored webs on the flowers and foliage. Apply a miticide, according to package directions, at the first sign of an infestation.
