Growing Instructions from Seeds

Sow the seeds approximately:

0.5–1 cm deep

in seedling trays, pots, grow bags or directly into prepared garden soil.

Seeds may also be sown directly into their final flowering position where growing conditions are suitable.

Keep the growing medium:

Lightly and consistently moist until germination.

Once seedlings become established, thin them if necessary to maintain good airflow and sufficient growing space.

Germination

Seeds generally germinate within:

7–14 days

under suitable conditions.

For successful germination:

• Use fresh seeds

• Maintain mild-to-warm temperatures

• Keep the growing medium lightly moist

• Avoid sowing too deeply

• Maintain good drainage

• Avoid continuous waterlogging

Plant Spacing

Maintain approximately:

20–30 cm / 8–12 inches between plants

to provide enough room for each plant to develop its natural bushy and spreading form.

Sunlight

Provide:

Full sun

For compact plants and abundant flowering:

6+ hours of direct sunlight daily

is recommended where possible.

Watering

Water regularly while seedlings are becoming established.

After establishment:

Water when the upper soil layer begins to dry.

Keep the soil moderately moist but well-drained.

Avoid continuous waterlogging.

Growth Habit

Unlike many Ipomoea Morning Glory varieties, Convolvulus tricolor is not a vigorous tall climbing vine.

It develops a:

Compact, bushy and spreading growth habit

and normally does not require a trellis.

It is especially suitable for:

• Flower beds

• Borders

• Pots

• Patio containers

• Grow bags

• Mass flowering displays

• Low edging displays

Feeding

At planting time, mix:

GREEN GARDENS Vermicompost

into the growing medium.

Convolvulus performs well in moderately fertile, well-draining soil enriched with organic matter.

Avoid excessive nitrogen fertilizer, as excessive foliage growth may reduce flowering.
