Growing Instructions from Seeds

For improved germination:

Soak seeds in water for approximately 8–12 hours before sowing.

Sow approximately:

0.5–1 cm deep

and cover lightly with fine growing medium.

Keep the growing medium:

Lightly and consistently moist until germination.

Once seedlings begin active growth, provide a trellis, net, fence or other suitable climbing support.

Germination

Seeds generally germinate within:

7–21 days

under suitable warm conditions.

For successful germination:

• Use fresh seeds

• Maintain warm temperatures

• Keep the growing medium lightly moist

• Avoid deep sowing

• Maintain good drainage

Plant Spacing

Maintain approximately:

30–45 cm / 12–18 inches between plants

when growing several vines together.

Adequate spacing allows stronger branching, better airflow and a fuller flowering display.

Sunlight

Provide:

Full sun to partial sun

For vigorous growth and abundant flowering:

5–6+ hours of bright sunlight daily

is recommended.

In Lahore's intense midsummer conditions, some protection from harsh late-afternoon sun can be beneficial.

Watering

Water regularly while young vines are becoming established.

After establishment:

Water when the upper soil layer begins to dry.

Keep the growing medium moderately moist but well-drained.

Avoid continuous waterlogging.

Support

Black Eyed Susan Vine is a natural twining climber.

Provide:

Trellis, netting, fence, railing or other vertical support

early in the growing stage.

Guide young stems gently onto the support to encourage an attractive vertical flowering display.

Feeding

At planting time, mix:

GREEN GARDENS Vermicompost

into the growing medium.

Light balanced feeding during active growth can support healthy vine development and flowering.

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