We, the Amaryllis bulbs, are tropical and subtropical beings at heart. While many know us as forced indoor winter bloomers, our true nature thrives in the consistent warmth of zones 9-11. Our growth cycle is intrinsically tied to the seasons here. We require a distinct period of winter dormancy, triggered by slightly cooler temperatures and drier conditions, to recharge for our spectacular spring performance. The warm, wet summers provide the ideal energy-gathering period through our photosynthesizing leaves, fueling the next season's flower production. This cycle of growth, rest, and bloom is the fundamental rhythm of our lives in your garden.
To flourish, we demand a planting site that mimics our native habitat. We crave abundant sunlight, but in the intense heat of a zone 9-11 afternoon, we appreciate some light, dappled shade to prevent our foliage from scorching. Most critically, we require exceptionally well-draining soil. Our bulbs are prone to rot if left sitting in waterlogged earth. Please plant us in a raised bed or on a gentle slope, and amend heavy clay soil with generous amounts of compost, perlite, or coarse sand. When planting, set us in the ground with the top third of our bulb neck exposed above the soil line; being buried too deeply is a primary cause of our distress and failure to thrive.
Our watering needs change dramatically with our growth cycle. During our active growth phase in spring and summer, we desire consistent moisture. Water us regularly, allowing the top inch of soil to dry out between waterings. As autumn approaches and our foliage begins to yellow and die back naturally, you must significantly reduce watering. This dry period is our signal to enter dormancy. During our winter rest, we need the soil to be almost completely dry. As for food, we are heavy feeders during our growth period. Feed us monthly with a balanced, water-soluble fertilizer as our leaves emerge and grow. Once our flower stalks appear, switch to a fertilizer higher in phosphorus to support spectacular blooming. Cease all feeding once we enter our dormant period.
Unlike in colder zones, you do not need to dig us up for winter. We can remain in the ground year-round. Our dormancy is not as absolute as it is in freezing climates; it is more a period of rest. You may notice some of our foliage remaining semi-evergreen. However, to ensure vigorous blooming, it is crucial to respect our need for a drier, cooler rest. Withhold water and fertilizer during the late fall and early winter. As the days begin to lengthen again and temperatures subtly rise, a good soaking of water will signal us to break dormancy and send up new flower stalks and leaves. Over the years, we will naturalize, multiplying and forming impressive clumps that will produce more dazzling floral displays each season.
