When to plant
Plant Galtonia bulbs in early spring once frost risk has receded and before growth takes off. In mild climates, the bulbs may also go in slightly earlier if soil conditions are favorable.
Where to plant
Choose a position with full sun to part shade. Ensure that the location is sheltered from strong winds, as the stems can sway when heavy with blooms. The soil must be well-drained, as Galtonia hates sitting in water.
Preparing the soil
Draw the soil up to around 20–25 cm, removing debris, rocks, or hard clods. Work in compost or well-rotted organic matter to boost fertility. If your soil tends to retain moisture, mix in grit or coarse sand to ensure better drainage.
Planting the bulbs
Set bulbs pointed tip up, placing them about 10–15 cm deep. Space them generously — around 25–40 cm apart — to allow for air circulation and future growth of stems and foliage.
After planting
Water gently but thoroughly to help the soil settle around the bulbs. Keep the bed evenly moist as shoots develop, but don’t overwater — let soil dry slightly between waterings once plants are established.
During growth & blooming
As stems elongate and flowers form, keep the soil consistently moist — not soggy. Feed lightly when buds appear to support robust flowering. When blossoms appear, they hang in charming clusters of white bells. Remove spent flower stalks to maintain a tidy appearance.
After blooming / end of season
Allow foliage to die back gradually — this helps replenish the bulb for future seasons. In colder climates, once leaves wither fully, lift bulbs, dry them, and store them in a cool, dry environment until the next planting season. In frost-free regions, mulch over winter and leave bulbs in the ground.
Extra tips
Galtonia pairs beautifully with late summer perennials and grasses — the white bells contrast well with deeper hues. Because the bloom season is later, it helps bridge summer into fall with fresh vertical accents. Use bulks or drifts rather than single specimens for full effect. Ensure air circulation around plants to prevent damping-off in humid conditions.
