Selecting Amaryllis Bulbs
The first step for growing gorgeous amaryllis blooms is choosing your bulbs wisely. Look for large, healthy bulbs from reputable suppliers that are likely to yield robust, vibrant flowers after planting. Specific varieties offer unique flower shapes, sizes, and even scents.
Healthy Bulbs
Inspect amaryllis bulbs for any signs of mold, damage, or rotting, and avoid purchasing these. Select heavy, firm bulbs without blemishes that are at least 2 inches in diameter. Larger bulbs between 3 to 5 inches across tend to produce more spectacular blooms on stronger flower stalks.
Variety Choice
Popular amaryllis varieties include:
- Double King: Large, frilly double red blooms
- Apple Blossom: Sweetly fragrant pink flowers
- Minerva: Vibrant crimson-red with lime-green throats
- Ever Green: Lime green and white striped petals
Choose single or double blooms, along with colors like red, white, pink, or multi-hued varieties. Certain amaryllis bulbs are also scented, offering a wonderful fragrance along with beauty.
Preparing for Planting
Before planting your amaryllis bulbs, take a few simple steps to prepare them for enhanced growth and ensure excellent flowering. Setting up your amaryllis bulbs properly helps nurture success.
Bulb Inspection
Inspect each amaryllis bulb closely before planting, removing any dried roots or scales from the base. Look for a dried, flat circle on the bottom, known as the basal plate, where roots emerge. Keep this plate intact, but carefully strip off any old roots or loose outer layers so new roots can form.
Timing
Amaryllis bulbs can be planted anytime from October through early spring. Most gardeners aim for late fall planting to enjoy winter flowers inside. Allow 6 to 8 weeks between planting and the initial blooms opening. Earlier planting gives more time for root growth first.
If aiming for specific bloom times like the holidays, count backwards from your goal to determine the right planting date. Refrigerate bulbs for 6 to 8 weeks beforehand if needed to replicate dormancy. Then, plant according to your desired flowering schedule.
Choosing the Right Pot and Soil
To support amaryllis bulbs for optimal growth and prepare for those prized blossoms, use an appropriate pot and planting mix to create an ideal foundation. This promotes healthy root systems, feeding blooms as they develop with spring.
Pot Size
Select a pot that’s about 2 to 4 inches wider than your amaryllis bulb. This allows ample room for root development without leaving excess space that retains too much moisture. Clay, ceramic, plastic, and metal pots are all fine choices. Include drainage holes at the base to prevent soggy soil. For a decorative touch, pick pots that complement your bulbs’ colors.
Soil Mix
Use a light, porous, and fast-draining potting mix amended with organic material like compost, peat moss, or leaf mold. Commercial African violet mixes work well. So does a blend of equal parts potting soil, perlite, or sand for drainage and compost. Just avoid regular garden soil, which stays overly damp.
Planting Amaryllis Bulbs in Pots
Now comes the fun part of actually planting your prepared amaryllis bulbs for months of continuing bloom and growth. With proper positioning in the pot and gentle soil coverage, you’ve given your bulbs an optimized start.
Positioning Bulbs
Place each amaryllis bulb in your selected pot with its basal plate down and pointed tip up. Bury bulbs are about one-third to halfway in the pot, allowing the top section with a “neck” to remain above soil level. Plant multiple bulbs together to cluster blooms.
Soil Covering
Fill pots with your soil mixture, firming it gently around each bulb base while leaving the neck and shoulders exposed. Ensure tops don’t fall below soil level, but don’t press too hard when firming soil. Finally, water in your planted amaryllis bulbs.
Watering Amaryllis Sparingly
While regular water nurtures amaryllis root growth after planting, take care not to overwater bulbs or leave them soggy. Excess moisture encourages fungal issues, bulb rotting, and weak flowering. Target moist, not wet soil, instead with smart watering strategies.
Initial Watering
After planting bulbs in their soil-filled pots, water them well by gently pouring water onto the soil surface. Avoid pouring directly over bulbs to prevent rot. Let excess water drain freely from pots after an initial deep soak.
Ongoing Care
When the soil surface feels dry to the touch an inch down, it’s time to water again. Target about 1 to 2 inches of total water weekly by watering lightly as needed, not on any fixed schedule. Ensure pots have drainage holes and drip trays to remove excess moisture.
Growing Amaryllis in Stones and Water
While most gardeners grow potted amaryllis in soil mixes for moisture retention and nutrients, an intriguing alternative involves forgoing soil entirely. Known as water culture growing, planting bulb bases in pebbles with water alone can yield amazing results.
Setup Process
Start by covering the base of a glass vase or jar with several inches of pebbles like river rocks or marbles. Nestle clean, prepped amaryllis bulbs firmly into the rocks with their basal plates down and necks above the pebbles. Then, fill vases with enough water to submerge pebble bases fully while not touching the bulbs.
Maintenance Tips
Replenish evaporated water as needed to maintain levels for submerged pebble bases. Refresh the vase water weekly and scrub any slime accumulation on glass or pebbles using diluted bleach. Remove fading blooms and exhausted foliage over time once flowering finishes. Enjoy unique amaryllis displays!

Maximizing Flower Blooms
To achieve the most prolific bloom displays from your planted amaryllis bulbs, optimize two key environmental inputs – sunlight and nutrition. Taking steps to properly support your bulbs results in radiant amaryllis flowers.
Sunlight Exposure
Place pots or vases in a sunny, south-facing window once bulb sprouts or leaves emerge. At least six hours of direct sun daily results in the greatest flowering potential. Turn pots regularly and prune excess foliage, blocking light penetration.
Insufficient light leads to tall, spindly flower stalks that struggle to support huge amaryllis blooms properly. Supplement with grow lights if adequate natural light isn’t available.
Fertilizing
Using soluble houseplant fertilizer encourages amaryllis flowering and replenishes nutrients that bulbs expend to bloom. Apply fertilizer every 2 to 4 weeks from initial sprouting until 6 weeks after flowering finishes. Dilute liquid formulas to half-strength. Granular fertilizers can be used at full strength.
Caring After Blooming
Once your amaryllis finishes that spectacular flowering display, proper care is vital for getting reblooms in the following years. Nurture bulb growth instead of discarding plants post-bloom for ongoing beauty.
Deadheading
Snap off faded blooms just behind the flower heads rather than cutting the entire flowering stalks down after petals wither. This preserves foliage, which continues to produce nutrients the bulb needs through photosynthesis. Let stalks and leaves fully die back naturally.
Foliage Care
Keep watering and fertilizing amaryllis, whose foliage remains green post-blooming. Place pots outdoors in a sunny spot once overnight temperatures stay reliably above 50°F. Bring bulbs back inside in the fall before the first frost for 8 to 10 weeks of rest.
Tips for Reblooming Amaryllis
The most common gardening myth about amaryllis is that they only bloom once and then must be discarded. But in fact, with proper care, amaryllis frequently rebloom year after year as spectacular as that first show. Follow key dormancy and replanting steps for ongoing blooms.
Dormancy Period
Amaryllis bulbs require an annual dormant period to store up the energy needed for repeat flowering cycles. After growing foliage outdoors dies back in late summer, cut faded stalks to 2 inches above bulbs’ necks. Bring pots inside and stop watering, allowing bulbs to go dormant.
Leave bulbs dry at about 50°F for 8 to 10 weeks. The foliage and roots will dry up, and bulbs may even slightly shrivel, but this period of rest is vital to spark reblooms. Don’t discard dormant bulbs that appear lifeless!
Replanting Bulbs
After sufficient dormancy, replant bulbs starting in mid-fall following the same instructions. Mix in new potting soil, replenish any depleted nutrients with organic matter additions and water sparingly after planting dormant bulbs.
Within 6 to 8 weeks, flower stalks will again emerge for a repeat show. For the greatest flowering potential, divide bulbs every 3 to 5 years as clumps enlarge.
Dealing with Pests and Diseases
Fortunately, amaryllis bulbs are relatively hassle-free without serious pest or disease issues in container plants. Monitor bulb health and respond promptly at the first sign of any potential problems to keep your amaryllis blooming wonderfully year after year.
Common Issues
Occasionally, amaryllis suffers from fungal diseases like red blotch, bulb rots, or leaf spots if overwatered. Slugs or snails may chew foliage or transmit bacterial soft rots. Care for overall plant vigor and promptly remove any damaged, infected bulbs to stop spreading issues.
Prevention Strategies
The best offense is a good defense by promoting optimal amaryllis health with excellent care. Allow soil to dry between waterings, provide bright sunlight, fertilize plants, and inspect regularly. Ensure adequate air circulation between leaves. Disinfect pots and pruning shears to avoid spreading disease.
