Gypsophila Snowflake

Climate & Timing 

Sowing Time:

• In frost prone areas, sow seeds in spring after the last frost (September–November).
• In frost free regions, autumn sowing (March–May) is also suitable for extended blooms. 

 Avoid extreme heat or cold, as these conditions hinder germination. 

Soil Preparation 

 Soil Type:

• Gypsophila thrives in well drained, sandy, or gritty soil with a slightly alkaline pH (6.5–7.5).
• Avoid heavy clay soils. 

 Amendments:

• If soil is acidic, add garden lime to raise ph.
• Gypsophila prefers poor to moderately fertile soil so avoid over enriching with compost or manure. 

Sowing Instructions 

Direct Sowing:

• Scatter seeds 3 mm deep, spacing 25 cm apart, crowding promotes better blooms. 

Germination:

• Seeds sprout in 7–14 days at 10 – 22°C.
• Keep soil moist but not waterlogged. 

 Containers:

• Use pots greater than 10L with quality potting mix.
• Ensure drainage holes to prevent root rot. 

Care Tips 

Watering:

• Water deeply but infrequently—allow soil to dry 10cm below the surface between watering.
• Avoid wetting foliage to prevent fungal issues. 

Feeding:

• Avoid high nitrogen fertilisers.
• Apply a high potassium liquid feed (e.g., tomato fertiliser) during flowering for a boost. 

Support:

• Tall varieties may need stakes or trellises.
• Install supports early to avoid root disturbance. 

Harvesting 

Cut Flowers:

• Harvest stems when half the flowers are open, ideally in the morning.
• Place in water immediately. 

Drying:

• Cut stems when 50% of blooms are open.
• Hang upside down in a dark, ventilated area until papery. 

Troubleshooting 

Pests:

• Aphids, spider mites, and thrips can be managed with insecticidal soap or eco oil. 

Diseases:

• Root rot from overwatering—ensure soil drainage.
• Gray mould (Botrytis) is treated by removing affected parts and improving airflow. 

Companion Planting Guide 

Best Companions 

• Lavender: Repels pests (e.g., aphids) and shares Gypsophila’s love for full sun and dry soil. 
• Marigolds: Deter nematodes and add vibrant colour contrast. 
• Echinacea (Coneflower): Attracts pollinators and thrives in similar drought tolerant conditions. 
• Salvia: Tall, upright growth complements Gypsophila’s airy texture. 
• Coreopsis: Offers long lasting blooms and harmonizes with Gypsophila’s care needs. 

Plants to Avoid 

• Peonies: Compete aggressively for nutrients. 
• Cabbage Family: Attracts pests like cabbage worms. 
• Fennel: Releases growth inhibiting chemicals. 

Seed Saving Guide 

Harvesting Seeds 

Timing:

• Let flowers fully mature and dry on the plant.
• Seeds are ready when pods turn brown and rattle. 

Method:

• Place a paper bag over seed heads before cutting stems to catch fine seeds.
• Shake gently to separate seeds from debris. 

Storage Tips 

Viability:

• Gypsophila seeds remain viable for 2–4 years if stored properly. 

Conditions:

• Store in an airtight container (e.g., glass jar) with a desiccant.
• Keep in a cool, dry place.
