Schubertii Allium Bulb

Schubertii Allium Plants, also known as the Tumbleweed Onion, are a marvel to have in the landscape. Huge 12-inch blooms resemble a red sparkler and add interest to any area. They easy to grow, make excellent cut flowers and attract bees, butterflies, and hummingbirds. This explosion of beauty tolerates heat and drought while deer and rabbits tend to avoid them. Recommended spacing for fall planted Schubertii Allium bulbs is 5 inches apart at a depth of 8 inches.

Planting Instructions:

• - Plant Schubertii Allium bulbs in the fall, about 6-8 weeks before the first hard frost.
• - Choose a sunny location that receives at least 6-8 hours of direct sunlight daily.
• - Prepare the soil by loosening it to a depth of at least 12 inches and incorporating organic matter, such as compost, for improved drainage and fertility.
• - Plant the bulbs 6-8 inches deep, with the pointed end facing upwards.
• - Space the bulbs about 12-18 inches apart to allow for their large flower heads and foliage.

Soil Preparation:

• - Alliums prefer well-drained soil; if your soil retains too much moisture, mix in sand or gravel to improve drainage.
• - Aim for a soil pH between 6.0 and 7.0 for optimal growth.

Watering Specifics:

• - Water thoroughly after planting to help settle the soil around the bulbs.
• - Keep the soil slightly moist during the growing season, but avoid overwatering.
• - Reduce watering once the foliage begins to yellow and die back after blooming.

Fertilizer Type:

• - Use a balanced, slow-release fertilizer at planting to support initial growth.
• - A second application in early spring can help promote strong growth and flowering.
• - Avoid high-nitrogen fertilizers, as these can encourage excessive foliage at the expense of flowers.

Pruning and Care:

• - Deadhead spent flowers to prevent seed formation and encourage bulbs to store energy for next year.
• - Allow the foliage to remain until it has yellowed completely to help the bulbs replenish their energy for the following season.
• - After the foliage has died back, it can be removed to tidy up the garden.

Pest Management:

• - Generally pest-resistant, but watch for aphids and other small insects.
• - If pests appear, use insecticidal soap or neem oil as a treatment.
• - Ensure good air circulation around plants to help prevent fungal diseases.

Blooming Indicators:

• - Schubertii Allium typically blooms in late spring to early summer, producing unique star-shaped flower heads.
• - The flowers are purple-pink and can be quite large, measuring 6-10 inches across.
• - Plants usually reach a height of 18-24 inches, making them a striking addition to borders or mixed beds.

Light Requirements:

• - Requires full sun for best results; partial shade is acceptable but may reduce blooming.
• - Ensure ample sunlight to encourage robust growth and vibrant flowers.

Temperature Tolerance:

• - Hardy in USDA zones 4-8.
• - Alliums need a cold dormancy period in winter to thrive and bloom in spring.
