Spike, commonly known as Dragon Tree or Red-edged Dracaena, is a popular indoor foliage plant characterized by thin, arching green leaves with reddish or burgundy margins.

Growth Stages

1

Establishment

4-6 weeks

Young Spike plant with compact growth, typically 1-3 feet tall with thin stems and sparse foliage

Keep soil lightly moist but not waterlogged; provide bright indirect light; avoid moving plant frequently to reduce shock

2

Vegetative Growth

6-12 months

Plant develops multiple leaf clusters along woody stems; height increases gradually to 3-6 feet or more

Maintain consistent watering schedule; fertilize monthly during growing season (spring/summer); rotate plant quarterly for even growth

3

Mature Specimen

2+ years

Full-sized plant reaching 4-10 feet tall with dense arching leaves and prominent woody trunk; may develop multiple stems from base

Reduce fertilizing frequency; prune leggy stems to encourage bushier growth; wipe leaves monthly with soft damp cloth to maintain shine

4

Flowering (occasional)

1-2 weeks if it occurs

Rarely flowers indoors; when it does, produces small cream or pale yellow tubular flowers in clusters

Flowering is rare in household conditions and doesn't require special care; remove flowers if they develop to direct energy to foliage

Harvest Tips

Not harvested for food or material; instead, prune stems 1-2 inches above leaf nodes to maintain shape and encourage branching. Pruning can be done year-round, with best results during growing season. Use sharp, clean pruners to prevent disease.
