Nemesia Growing Guide

Nemesia hybrids

Crop Rotation Group

Miscellaneous ●

Soil

Fertile, well-drained soil enriched with plenty of compost, or any good quality potting soil for containers.

Position

Full sun to partial afternoon shade.

Frost tolerant

No. Nemesias grow best as cool-season annuals.

Feeding

None generally required when nemesias are grown in fertile beds. In containers, plants benefit from a drench with a dilute liquid organic fertiliser every three weeks.

Spacing

Single Plants: 15cm (5") each way (minimum)
Rows: 15cm (5") with 15cm (5") row gap (minimum)

Sow and Plant

Nemesia is not difficult to grow from seed, but it is easier to purchase bedding plants when they become available in spring. Set out seedlings or get them situated in containers in spring, while the weather is still cool. Nemesia can also be sown in late summer and autumn for warmer areas that don't get frost.
Our Garden Planner can produce a personalised calendar of when to sow, plant and harvest for your area.

Notes

Older varieties of nemesia were sensitive to heat and bloomed only in yellow and orange, but modern strains are much more resilient. Some are fragrant. The intricate blossoms resemble little orchids and are wonderful viewed up close in containers.

Harvesting

Snip off old blossoms to keep the plants looking neat, and to encourage reblooming.
