PLANTING and AFTERCARE GUIDE

Best Planting Time

The best time to plant Allium ‘Lavender Bubbles’ is in autumn. This allows the bulbs to establish well before the growing season, ensuring they bloom beautifully the following summer. Planting during this period gives Allium ‘Lavender Bubbles’ the best chance to develop strong roots and flower abundantly.

Ideal Location

• Sunlight: Allium ‘Lavender Bubbles’ thrives in full sun. Choose a location where the plant will receive at least 6 hours of direct sunlight each day. This promotes healthy growth and encourages vibrant blooms.
• Soil: Well-drained soil is essential for Allium ‘Lavender Bubbles’. This plant does not tolerate waterlogged conditions, so improve drainage by adding grit or organic compost to the soil if necessary.

How to Plant Allium ‘Lavender Bubbles’

1. Prepare the Hole: Dig a hole that is about three times the depth of the bulb. Space each bulb about 10-15 cm apart to allow room for growth and airflow between plants.
2. Soil Preparation: Mix organic matter such as compost into the soil to enhance fertility and drainage. Allium ‘Lavender Bubbles’ will benefit from nutrient-rich, well-drained soil.
3. Planting: Place the bulb into the hole with the pointed side up. Gently cover the bulb with soil and lightly press it down to eliminate air pockets.
4. Watering: After planting, water the area lightly to help settle the soil around the bulbs. Avoid overwatering, as this can lead to rotting.

Watering Requirements

• Growing Season: Allium ‘Lavender Bubbles’ is relatively drought-tolerant once established. Water sparingly during dry spells, allowing the soil to dry out between watering sessions.
• Dormant Season: During dormancy in autumn and winter, reduce watering. Overwatering during this time can cause bulb rot, so only water if the soil becomes excessively dry.

Feeding

For best results, feed Allium ‘Lavender Bubbles’ with a balanced fertiliser when planting. A second light feeding in spring can help support vigorous growth and encourage abundant flowering throughout the summer months.

Pruning and Deadheading

• Deadheading: Once the blooms of Allium ‘Lavender Bubbles’ start to fade, cut them back to encourage the plant to focus its energy on building up the bulbs for next year’s growth.
• Foliage Maintenance: Allow the leaves to die back naturally after flowering. This is important as the foliage helps the bulbs store energy for the next blooming season.

Mulching for Healthier Growth

• Spring Mulching: Apply organic mulch, such as compost or bark chips, around the base of the plant in the spring. This helps to conserve moisture, suppress weeds, and regulate soil temperature.
• Winter Mulching: Adding a protective layer of mulch in late autumn can help insulate the bulbs from extreme cold, ensuring they remain healthy throughout the winter.
