PLANTING and AFTERCARE GUIDE

Best Time to Plant

For the best results, plant Allium hollandicum ‘Little Sapphire’ bulbs in autumn. This gives the bulbs time to establish their root systems before winter, ensuring robust growth and stunning blooms the following summer. The bulbs prefer loose, well-drained soil when being planted.

Site Selection

Allium hollandicum ‘Little Sapphire’ flourishes in full sun. Choose a location that receives at least 6 hours of sunlight each day to encourage vibrant blooms and strong, upright stems. Good drainage is crucial for this plant; soggy soil can lead to bulb rot. If necessary, improve drainage by incorporating grit or organic matter like compost into the planting area.

Planting Instructions

1. Soil Preparation: Before planting, loosen the soil to a depth of about 10-15 cm. Adding compost will improve the soil’s structure and drainage, which is vital for Allium hollandicum ‘Little Sapphire’.
2. Planting Depth and Spacing: Dig holes 10-15 cm deep, about three times the height of the bulb. Space the bulbs approximately 10 cm apart to give them room to grow, but close enough to create an impressive floral display when they bloom.
3. Positioning the Bulbs: Place each Allium hollandicum ‘Little Sapphire’ bulb in the hole with the pointed end facing up. Cover with soil and lightly press down to eliminate air pockets.
4. Watering After Planting: Water the bulbs well after planting to help them settle into the soil. However, avoid overwatering as these bulbs do not thrive in overly moist conditions.

Watering and Fertilising

Allium hollandicum ‘Little Sapphire’ is drought-tolerant once established. Water moderately after planting and throughout the growing season, allowing the soil to dry slightly between waterings. This plant prefers a balance—neither too dry nor too wet.

For optimal growth, apply a balanced fertiliser in early spring when the first shoots appear. This will provide essential nutrients for the plant’s growing phase. Additional feeding during the growing season isn’t necessary unless your soil is particularly poor.

Pruning and Maintenance

Once the Allium hollandicum ‘Little Sapphire’ flowers fade, you can deadhead them if you prefer a neat garden appearance. The seed heads, however, provide a decorative touch and can be left intact. The foliage will naturally die back after flowering; leave it to wither completely before removing it, as this allows the plant to store energy for the next year’s blooms.

Mulching and Winter Protection

Although Allium hollandicum ‘Little Sapphire’ is hardy, adding a layer of mulch in late autumn will protect the bulbs from harsh winter temperatures. Organic mulches like bark chips or compost work well to insulate the bulbs and retain moisture in the soil.

Pests and Diseases

Allium hollandicum ‘Little Sapphire’ is relatively pest-resistant. Its strong scent deters most garden pests like deer and rabbits. However, keeping the soil well-drained will help avoid issues with bulb rot or fungal diseases, which can occur in overly damp conditions.

Companion Planting

Allium hollandicum ‘Little Sapphire’ pairs beautifully with other summer-flowering perennials such as lavender, salvias, and ornamental grasses. The tall, delicate stems contrast wonderfully with shorter, bushier plants, creating a dynamic and colourful display in your garden.

Final Tips for Growing Allium hollandicum ‘Little Sapphire’

Allium hollandicum ‘Little Sapphire’ is an excellent choice for adding structure, height, and a soft color palette to your garden. Its compact size and sturdy growth make it ideal for smaller spaces, borders, and containers. By following the right planting techniques, ensuring good drainage, and providing plenty of sunlight, your Allium hollandicum ‘Little Sapphire’ will reward you with beautiful blooms year after year.
