Growth Stages

1

Dormancy & Sprouting

4-8 weeks

Rhizomes lie dormant underground, gradually sending up shoots as soil warms in spring

Plant rhizomes in fall or early spring; ensure good drainage to prevent rot during dormancy

2

Vegetative Growth

6-10 weeks

Thin, wiry stems emerge with narrow lance-shaped leaves; plant develops bushy form with multiple stems

Water regularly; apply balanced fertilizer monthly; provide stakes or support if stems become tall and spindly

3

Bud Formation

2-3 weeks

Flower buds begin to form at stem tips, showing distinctive clustered arrangement typical of alstroemeria

Maintain consistent moisture; fertilize with higher phosphorus to encourage blooming; remove any damaged foliage

4

Flowering

8-12 weeks

Clusters of orange flowers with delicate, mottled petals open sequentially; each bloom lasts 1-2 weeks

Deadhead spent flowers to encourage continuous blooming; keep well-watered; cut stems for arrangements promote more flowers

5

Senescence & Dormancy

Variable depending on climate

Blooming slows as temperatures cool; foliage yellows and stems die back in fall/winter

Reduce watering; allow foliage to yellow naturally to build rhizome reserves; cut back stems to ground level before new growth

Companion Planting
