Your amaryllis bulbs after they bloom still have a full year of work ahead before the next flowers show up. Snip off each spent flower as it wilts. Then cut the stalk down to about 3-4 inches above the bulb once all flowers on that stalk have faded. Leave every green leaf alone because those leaves power next year's blooms.
Your after-bloom amaryllis care should treat the bulb like a regular houseplant for the next several months. Keep it in a bright window and water when the top inch of soil feels dry. Feed it with a half-strength balanced fertilizer once a month. I cut the leaves off along with the stalk my first year and that bulb refused to flower the next season. Those leaves were its only way to store energy for new blooms.
Those green leaves serve a purpose that most people overlook. They photosynthesize for 5-6 months straight and convert sunlight into stored energy inside the bulb. Your bulb draws on this energy reserve to produce flower stalks the following winter. Without enough leaf time in bright light, the bulb shrinks and may skip blooming altogether.
Deadheading amaryllis flowers at the right time helps your bulb keep more energy for itself. Colorblends recommends removing flowers in pairs as they fade. Don't wait for the whole stalk to finish. This stops the plant from wasting energy on seed production. Once you cut the stalk, your bulb channels all its resources into those hard-working leaves.
When summer arrives, move your potted amaryllis outside to a spot with morning sun and afternoon shade. I set mine on the back porch where they get about 6 hours of light each day. The fresh air and stronger sunlight boost leaf growth far beyond what a windowsill can offer. Bring the pot back inside before nighttime temps drop below 55°F (13°C) in early fall.
UMN Extension confirms that a healthy amaryllis bulb can rebloom for up to 75 years. Your effort after flowering pays off for decades. Each year the bulb grows a bit larger and produces more stalks. A bulb that gave you one stalk this year might push out two or three after a few seasons of good care.
Late Winter to Spring
- Cut spent stalks: Trim each flower stalk to 3-4 inches above the bulb after all blooms on that stalk have wilted and dried.
- Keep all leaves: Let every green leaf stay on the plant since they need to gather sunlight for the next 5-6 months straight.
- Start fertilizing: Begin a half-strength balanced fertilizer every 4 weeks to give the bulb nutrients for energy storage.
Summer Months Outdoors
- Move outside: Place the pot in a spot with morning sun and afternoon shade once nighttime temperatures stay above 55°F (13°C).
- Water and feed: Keep watering and fertilizing on the same monthly schedule throughout the entire summer growing period.
- Watch for pests: Check leaves for red blotch fungus or mealybugs every week since outdoor conditions invite new problems.
Late August to October
- Stop fertilizing: Cut off all fertilizer by late August so the bulb gets the signal that the growing season is winding down.
- Reduce water: Slowly cut back watering over 2-3 weeks until the leaves yellow and die back on their own.
- Start dormancy: Move the bulb to a cool dark spot at 45-55°F (7-13°C) for 8-10 weeks to trigger new flower bud formation.
I now keep a calendar reminder for each step so I never miss a window. The whole cycle feels natural once you have done it twice. You get a bigger bulb with more flowers every single year. Your patience during those quiet leaf-growing months turns a one-time holiday gift into a plant that outlasts most furniture in your house.
