From the perspective of an amaryllis plant, reblooming is a natural process tied to its life cycle. After flowering, the plant enters a growth phase where it stores energy in its bulb for the next season. To rebloom, the bulb must undergo a period of dormancy, followed by renewed growth. Without this cycle, the plant won’t have the resources to produce another stunning display of flowers.
After the flowers fade, the amaryllis shifts its focus to photosynthesis and nutrient storage. To support this, keep the plant in bright, indirect light and continue watering it regularly. Fertilize every 2–4 weeks with a balanced liquid fertilizer (10-10-10) to replenish the bulb’s nutrients. The leaves are critical—they absorb sunlight and convert it into energy stored in the bulb. Avoid cutting them back until they yellow and wither naturally.
As daylight decreases in late summer or early fall, the amaryllis senses the changing seasons and prepares for dormancy. To mimic this, gradually reduce watering and stop fertilizing. Move the plant to a cool (50–60°F or 10–15°C), dark location for 8–10 weeks. This simulates the dry, cool period the bulb would experience in its natural habitat, signaling it to rest and conserve energy for reblooming.
After the dormancy period, the amaryllis is ready to begin a new growth cycle. Bring the bulb back into bright light and resume watering lightly. The plant will send up new flower stalks and leaves. If the bulb has outgrown its pot, repot it in fresh, well-draining soil, leaving the top third of the bulb exposed. This ensures the roots have space to grow and access to oxygen.
To encourage robust blooms, maintain consistent care. Provide at least 6 hours of indirect sunlight daily and water when the top inch of soil feels dry. Avoid overwatering, as soggy soil can rot the bulb. A temperature range of 65–75°F (18–24°C) is ideal during active growth. Rotate the pot occasionally to ensure even light exposure, preventing the plant from leaning toward the light source.
If the amaryllis fails to rebloom, it may lack sufficient energy due to inadequate light, improper dormancy, or nutrient deficiency. Ensure the bulb is large and healthy—smaller bulbs may skip a blooming season. Pests like aphids or spider mites can also weaken the plant. Inspect leaves regularly and treat infestations promptly with insecticidal soap or neem oil.
For ongoing reblooming success, the bulb must remain healthy. After several years, offsets (small bulblets) may form. These can be separated and grown into new plants, but they may take 2–3 years to bloom. Store bulbs properly during dormancy, avoiding freezing temperatures or excessive moisture. With consistent care, an amaryllis bulb can rebloom for decades, becoming a cherished seasonal highlight.
