Whether you grow amaryllis flowers indoors by forcing the bulbs to bloom or you live in a region where outdoor growing is possible, growing amaryllis flowers can be rewarding and exciting. When you see the green shoot begin extending from the bulb, this tells you the time has come to begin to regularly water the amaryllis plants. Watering an amaryllis requires careful observation to prevent over-watering. If you over-water an amaryllis, the bulb may decay and the plant will cease growing.
Watch a potted amaryllis bulb carefully so you will know when the stem begins to grow. Before the stem begins growing, do not give more than a small amount of water to the bulb, enough to lightly moisten the soil.
Provide water to moisten the potting soil evenly at the first appearance of green growth at the tip of the bulb.
Wait until the soil dries before moistening the soil with water again. When the soil is dry 1 inch below the soil surface, moisten the soil. A typical watering schedule for amaryllis bulbs is once per week. Continue the same watering schedule until the amaryllis plant blooms and then the bloom fades.
Allow the soil to dry completely between watering after the bloom fades. You must continue to water the amaryllis bulb while the foliage remains green, though, because the foliage will continue to nourish the bulb. Provide water only to moisten the soil lightly.
Cut the foliage from the bulb when it yellows and fades. At this point, stop watering the amaryllis bulb and allow it to enter dormancy. While the bulb is dormant, give it no water. Resume watering again when you see the green shoot reappear at the top of the bulb.
- Ensure the water drains thoroughly through holes at the bottom of the container. Do not allow the container to sit in a saucer of water. If you have a saucer beneath the container, empty it after watering the amaryllis. Water beneath the container may contribute to bulb decay.
