Dormancy/Planting
1-2 weeks after planting before growth beginsAmaryllis bulb is dormant and dry, ready for potting. Bulb appears firm with dry papery outer layers.
Select a pot only slightly larger than the bulb (1-2 inches clearance on sides). Use fresh, well-draining potting mix. Plant with top third above soil.
Sprouting
1-2 weeksGreen shoots emerge from the top of the bulb. Typically one to three stems begin elongating rapidly.
Place in bright, warm location (65-75°F ideal). Water moderately when soil surface is dry. Provide support stake if available. Ensure good air circulation.
Stem Elongation
2-3 weeksTall green stems (18-24 inches) develop with visible buds forming at the tip. Stems continue to lengthen and strengthen.
Maintain bright light to prevent weak, spindly growth. Rotate pot every few days for balanced growth. Keep soil consistently moist but not waterlogged. Apply dilute balanced fertilizer every 2 weeks.
Flowering
2-4 weeks (individual flowers last 5-7 days)Large trumpet-shaped flowers open sequentially from the top of the stem. Minerva displays striking red petals with white striping and white throat. Typically 2-6 flowers bloom per stem.
Avoid direct sunlight which may fade flower colors. Remove flowers as they fade to extend overall bloom period. Provide cool temperatures (60-65°F) to prolong blooms. Do not move or disturb flowering plant.
Post-Bloom & Recovery
6-8 weeks through summerFlowers fade and drop. Stems remain green and may produce seed pods. Foliage continues growing to replenish bulb energy.
Remove spent flower clusters but leave stems intact. Cut stems only after they yellow naturally. Continue watering and fertilizing through summer to build bulb strength. Move to cool location to encourage dormancy in fall (50-60°F).
Common Pests
-
Increase humidity, mist foliage regularly, isolate affected plant. Use neem oil or insecticidal soap if infestation is severe.
-
Remove with cotton swab dipped in isopropyl alcohol. Apply neem oil or horticultural oil if widespread.
-
Plant in well-draining soil, avoid overwatering. Use row covers during spring. Remove and discard infested bulbs immediately.
-
Inspect regularly, remove manually with brush. Apply horticultural oil in dormant season.
