Recommended Grow Bags

G-12 Grow Bag – 12 × 12 inch 🔗

Suitable for:

Growing one Shasta Daisy plant.

Because Mayfield Giant is a tall perennial:

G-12 is the preferred minimum size for individual container growing.

G-24 Grow Bag – 24 × 12 inch 🔗

Recommended for:

A larger root zone or a broader group planting where suitable spacing is maintained.

For long-term perennial growth:

Additional root space is beneficial.

Recommended Soil / Potting Mix

Use:

60% Bhalu Mitti / Sandy Soil + 30% GREEN GARDENS Vermicompost 🔗 + 10% Cocopeat

The growing medium should be:

Fertile, loose, moisture-retentive and well-draining.

Avoid:

• Heavy compact soil
• Poor drainage
• Standing water
• Continuously saturated soil
• Excessive nitrogen fertilizer

Shasta Daisies perform well in fertile soil where moisture is available but excess water drains freely.

Growing Instructions from Seeds

Shasta Daisy seeds may be started in:

Seedling trays, shallow nursery containers or carefully prepared pots.

Fill the tray with fine, moist and well-draining seed-starting medium.

Scatter the seeds:

Thinly over the surface.

Gently press them into contact with the growing medium.

Cover with:

Only a very fine sprinkling of soil, compost or vermiculite.

Keep the growing medium:

Lightly and consistently moist until germination.

Important Sowing Note

Avoid burying Shasta Daisy seeds deeply.

The seeds benefit from:

Light during germination.

Therefore:

Surface sow and apply only a very light covering of fine growing medium.

General Leucanthemum propagation guidance recommends surface sowing, a very fine covering and retaining light during germination.

Use:

Fine misting or very gentle watering

so the small seeds are not displaced.

Germination

Seeds generally germinate within:

10–14 days

under suitable conditions.

Good germination depends on:

• Suitable temperature
• Adequate light
• Consistent moisture
• Shallow sowing
• Fine growing medium
• Good drainage
• Seed freshness

Avoid:

Allowing the growing medium to dry completely or remain continuously waterlogged.

Ideal Germination Temperature

Recommended germination temperature:

15–20°C

This temperature range encourages:

Healthy and relatively uniform germination.

General Leucanthemum seed guidance also uses approximately 15–20°C during germination.

After germination:

Provide strong light and good air circulation to encourage sturdy young plants.

Transplanting

When seedlings become large enough to handle and develop several true leaves:

Transplant carefully into individual pots, grow bags or prepared flower beds.

Handle the root system gently.

Water after transplanting and allow young plants to establish before exposing them to unnecessary stress.

Plant Spacing

Maintain approximately:

40–60 cm / 16–24 inches between mature plants

where adequate space is available.

Mayfield Giant develops into a substantial perennial clump, so good spacing helps provide:

Strong growth, good airflow and room for large flowering stems. Historical cultivation guidance for large Shasta Daisy types recommends approximately 40–60 cm spacing.

Sunlight

Provide:

Full sun to light partial shade.

For strongest flowering:

Approximately 6+ hours of direct sunlight daily

is recommended.

A sunny position encourages:

Strong stems, healthy growth and abundant large flowers.

Watering

Keep young plants:

Moderately and consistently moist during establishment.

After establishment:

Water when the upper soil layer begins to dry.

Avoid:

Standing water and continuously saturated soil.

Established Shasta Daisies prefer:

Moist but well-drained conditions.

Feeding

At planting time, incorporate a moderate amount of:

GREEN GARDENS Vermicompost 🔗

into the growing medium.

Mayfield Giant benefits from:

Moderately fertile soil rich in organic matter.

During active vegetative growth:

Light balanced feeding may be applied when required.

Avoid excessive nitrogen because it may encourage:

Excessively soft leafy growth at the expense of strong flowering stems.

Flowering & Maintenance

Mayfield Giant produces:

Large white daisy flowers with golden-yellow centres on tall upright stems.

For healthy and prolonged flowering:

• Provide good sunlight
• Maintain moderate moisture
• Ensure good drainage
• Maintain adequate spacing
• Remove faded flowers regularly
• Avoid excessive nitrogen

Deadheading spent blooms

helps maintain a neat appearance and can extend the flowering display.

The long, strong stems also make Mayfield Giant particularly useful for:

Vases and cut-flower arrangements.

Perennial Care

Shasta Daisy Mayfield Giant is:

A perennial rather than an annual winter flower.

Under suitable conditions, established plants may return for multiple seasons.

Older clumps can eventually become crowded.

Where plants remain healthy for several years:

Clump division can be used to rejuvenate established plants and maintain vigour.
