📏
Spacing: 12-18 inches (as an epiphytic orchid, space baskets or pots to allow air circulation) inches
📅
Days to maturity: 3-4 years from seedling to first bloom
🌱
Planting depth: Plant with pseudobulbs at soil surface; do not bury deeply

Soil

Type: Orchid bark mix or coarse potting medium with excellent drainage
pH: 6.0-7.0
Amendments:
Orchid bark (medium to coarse grade) Perlite or pumice Sphagnum moss (sparingly) Charcoal for drainage and air circulation

Growth Stages

1

Dormancy/Rest

October-December

Plant sheds leaves in fall and appears bare with exposed pseudobulbs. Minimal growth activity. Lasts approximately 2-3 months.

Reduce watering significantly. Keep temperatures cool (50-60°F nights). Provide bright light. Do not fertilize. This rest period is essential for flowering.

2

Bud Emergence

January-February

After dormancy, flower buds emerge from the base of pseudobulbs before new leaves appear. Buds are visible and swelling.

Gradually increase watering and warmth. Maintain humidity around 60%. Resume light fertilizing. Ensure good air circulation to prevent bud drop.

3

Flowering

3-6 weeks (February-March typically)

Large, showy white flowers with pink or red sepals and lips appear in profusion. Blooms are fragrant and long-lasting.

Maintain consistent moisture without waterlogging. Keep temperatures moderate (55-70°F). Provide bright light. Do not move the plant while in bloom. Apply orchid fertilizer at half strength bi-weekly.

4

Vegetative Growth

April-September

New shoots and leaves emerge from the base of pseudobulbs. Plant grows vigorously with formation of new pseudobulbs.

Water regularly but allow slight drying between waterings. Fertilize every 1-2 weeks with balanced orchid fertilizer (equal NPK ratio). Maintain temperatures 65-80°F. Increase humidity to 60-80%.

5

Maturation

July-September

Pseudobulbs fully develop and mature. Plant reaches full size for the season. Growth begins to slow as fall approaches.

Continue regular watering and feeding through summer. Begin reducing water and fertilizer in late summer/early fall. Provide excellent air circulation and brightness.

Companion Planting

Plan your garden →

Plant with:

Other cool-growing orchids (Paphiopedilum, Odontoglossum) Anthurium Philodendron Bromeliads Ferns (in humid indoor gardens)

Avoid planting near:

Plants requiring frequent heavy watering (root rot risk) Heat-loving tropical plants (temperature mismatch) Plants sensitive to orchid-specific fertilizers

Common Pests

  • Increase humidity to 60-80%. Mist foliage regularly. Use neem oil spray or insecticidal soap if severe.

  • Remove with rubbing alcohol on cotton swab. Apply neem oil or insecticidal soap. Inspect pseudobulbs and leaf bases regularly.

  • Remove manually with rubbing alcohol. Apply horticultural oil spray. Treat every 7-10 days until resolved.

  • Ensure excellent drainage in orchid bark mix. Allow to dry slightly between waterings. Repot in fresh medium if suspected. Reduce humidity slightly around roots.

  • Remove affected pseudobulbs immediately. Disinfect cutting tools. Improve air circulation. Do not overwater.

Fun Facts

  • 🌱 Lycaste deppei is named after botanist Johann Friedrich Wilhelm Deppe and produces fragrant flowers that smell distinctly of almonds or cinnamon, with scent strongest in the morning hours.
  • 🌱 This orchid is deciduous, naturally shedding all its leaves in the dry season—an unusual trait among orchids—which allows it to survive seasonal drought in its native cloud forest habitat.
  • 🌱 Lycaste deppei requires a cool winter rest period with significant temperature drop (10-15°F difference from summer temperatures) to set flower buds; without this dormancy, the plant may not bloom.
