It is also essential to ensure that the soil is aerated properly to allow for root growth and development.
Cultivation Methods
Allium perdulce S.V. Fraser is a plant that is native to the western regions of North America, particularly in Oregon and California. It is a bulbous perennial that grows up to 12 inches tall. This plant prefers to be grown in well-drained soil and exposed to full sun or partial shade. It can be grown in containers or in garden beds. When planting, make sure to plant the bulbs at least 2 inches deep and 4 inches apart.
Watering Needs
Allium perdulce S.V. Fraser requires regular watering to maintain its health and growth. It prefers soil that is moist but not waterlogged, so make sure to water it deeply but infrequently. It is best to avoid overhead watering as it can cause damage to the leaves and flowers. Instead, water the soil around the plant base. During the hotter months, make sure to increase the frequency of watering to prevent the soil from drying out.
