Allium ‘Summer Drummer’ is a stunning perennial that adds height and drama to any garden. Caring for this particular allium is relatively straightforward, but there are a few key steps to ensure its success.
1. Planting: Allium ‘Summer Drummer’ should be planted in the early fall, ideally between September and November. Choose a location that receives full sun for at least six hours a day, as this will help the plant grow and bloom to its full potential. It’s important to select a spot that is sheltered from strong winds, as this can damage the tall flower stems.
2. Soil: These alliums prefer well-drained soil, so it’s important to prepare the planting area accordingly. If your soil is heavy or clay-like, you can improve drainage by adding organic matter, such as compost or well-rotted manure. This will help create a loose and fertile soil that allows water to drain away freely, preventing the bulbs from rotting.
3. Planting Depth: When planting ‘Summer Drummer’ allium bulbs, make sure to plant them at a depth of three times their own height. For example, if the bulb is 2 inches tall, it should be planted 6 inches deep. This will provide the bulbs with enough insulation during the winter months and prevent them from heaving out of the ground.
4. Watering: Alliums generally prefer dry conditions once they are established, so it’s important not to overwater them. During the growing season, water the bulbs sparingly, allowing the soil to dry out slightly between waterings. However, it’s essential to keep the soil evenly moist during the first few weeks after planting to help the bulbs establish their root systems.
5. Mulching: Applying a layer of mulch around the base of the alliums can help conserve moisture and suppress weed growth. Organic mulches, such as bark chips or straw, are ideal for this purpose. Be careful not to bury the bulbs too deeply with the mulch, as this can prevent them from emerging in the spring.
6. Fertilizing: Alliums generally don’t require much fertilizer, as they are relatively low-maintenance plants. However, if your soil is poor or lacks nutrients, you can apply a balanced, slow-release fertilizer in the spring before the bulbs start actively growing. Follow the package instructions for application rates, as over-fertilizing can lead to excessive foliage growth at the expense of flower production.
7. Deadheading: Once the flowers have faded, it’s a good idea to deadhead the spent blooms. This not only helps to keep the garden looking tidy but also prevents the plants from expending energy on seed production. To deadhead, simply snip off the flower stalks at their base using clean and sharp pruners.
8. Dividing: Over time, ‘Summer Drummer’ alliums may become overcrowded and produce fewer flowers. Dividing the bulbs every three to four years can help rejuvenate the plants and ensure optimal blooming. Wait until the foliage has completely withered before lifting the bulbs. Gently separate the individual bulbs and replant them at the same depth as before, spacing them about 6-8 inches apart.
Allium ‘Summer Drummer’ is a beautiful and relatively low-maintenance perennial that can add a touch of elegance to any garden. By following these care tips, you can enjoy its striking flowers for years to come.
