Convolvulus Growing Guide
Evolvulus
Crop Rotation Group
Miscellaneous ●
Soil
Fertile, well-drained soil.
Position
Full sun.
Frost tolerant
Can tolerate light frosts in warmer areas, where convolvulus can be grown as a short-lived perennial.
Feeding
Mix a light application of a balanced organic fertiliser into the soil prior to planting. In midsummer, drench plants with a liquid plant food to stimulate new growth.
Companions
Convolvulus can grow into somewhat floppy plants that benefit from close company with plants that produce lush foliage, such as parsley or ageratum.
Spacing
Single Plants: 30cm (11") each way (minimum)
Rows: 30cm (11") with 30cm (11") row gap (minimum)
Sow and Plant
Soak the hard seeds in water overnight before planting indoors, and keep the seeded pots warm. In areas with long summers, convolvulus can be sown directly into beds after the last frost has passed.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.
Notes
This flower is capable of blooming for six weeks in late summer. The plants look best when planted in groups. Colour options include blue, white, and pink.
Harvesting
Snip off spent blossoms to keep plants looking neat, and to prolong flowering.
Troubleshooting
This species can sometimes reseed, but the annual form (Convolvulus tricolour) is not invasive.
