When to Plant
Plant Gloriosa tubers in spring after the risk of frost has passed. In warm climates, you can start them indoors earlier and move them outside once soil warms. When autumn or frost approaches, tubers may need lifting for winter storage.
Where to Plant
Choose a site in full sun to part shade. The soil should be rich, moist when growing, and well-draining — Gloriosa dislikes waterlogged conditions. In regions with heavy rainfall, planting on slight mounds or in raised beds can help.
Preparing the Soil
Loosen the planting area to about 15–20 cm, remove debris and rocks, and mix in compost or organic matter to improve fertility and texture. Ensure the soil has good drainage to prevent tuber rot.
Planting the Tubers
Position tubers horizontally or slightly slanted, taking care not to damage the growing tips. Plant them about 7 cm deep (around 3 inches) and space them roughly 30 cm apart. Eyes or shoots — if visible — should face upward. Support structures like trellises or stakes should be in place before the vines start climbing.
After Planting
Water immediately after planting to help settle the soil. Keep soil consistently moist during the growing season but avoid saturation. Once growth begins, climbers will seek support — guide, but don’t force, their direction.
Summer Growth & Blooming
Vines will emerge and climb, with leaves twining via tendrils. Flowers generally appear mid-summer through fall. Feed lightly during growth for best flowering. Once the season ends, the stems will die back.
After Flowering
Allow foliage and stems to wither naturally before cutting back. In colder climates, dig up the tubers before the first frost, clean and dry them, and store in a cool, frost-free location. In mild zones, tubers may be left in the ground, provided drainage is excellent. Division is possible during dormancy but usually not necessary.
Extra Growing Tips
Gloriosa pairs beautifully with vertical structures like trellises or shrubs. Because the vine climbs by tendrils, training from early stages helps shape growth naturally. Always wear gloves and protective gear when handling, due to its toxicity. In containers, ensure excellent drainage and protect the tuber during cool months.
