Stephanotis: A Comprehensive Guide to Care and Cultivation
Overview
Stephanotis, also known as Madagascar jasmine or bridal flower, is a captivating flowering vine prized for its delicate white blooms and intoxicating fragrance. Native to Madagascar, stephanotis thrives in tropical climates with high humidity and warm temperatures. While it can be challenging to cultivate, with proper care, this exotic plant can bring beauty and aroma to any indoor or outdoor space.
Care Requirements
Light:
- Outdoors: Full sun or partial shade, with protection from scorching afternoon sun.
- Indoors: A sunny windowsill or under grow lights.
Soil:
- Well-draining potting mix with a high content of loam and peat moss.
- pH level between 5.5 and 6.5.
Water:
- Water sparingly, allowing the soil to dry out slightly between waterings.
- Avoid overwatering, as this can lead to root rot.
Temperature and Humidity:
- Stephanotis thrives in warm temperatures between 65 and 90 degrees Fahrenheit.
- High humidity is essential, especially during the growing season. Consider using a humidifier or placing the plant near a water feature.
Fertilizer:
- Fertilize monthly during the spring and summer with a balanced flower fertilizer.
- Stop fertilizing during the winter resting period.
Pruning:
- Prune lightly in late winter to maintain shape and encourage new growth.
- Remove side shoots to reduce the size of the plant and encourage bushier growth.
Propagation
Stephanotis can be propagated through stem cuttings:
- Take a cutting with 1-2 inches of stem and 2-3 leaves.
- Remove the lower leaves and dip the bottom of the cutting in rooting hormone.
- Insert the cutting into a pot filled with sand, peat, or perlite.
- Keep the cutting moist and provide high humidity.
- Cuttings will root in 4-6 weeks and may flower within a year.
Growing from Seed
Growing stephanotis from seed can be challenging, as it rarely produces fruit. If seeds are available:
- Harvest seeds from ripened pods and plant immediately.
- Fill a tray with potting soil and cover seeds with soil.
- Keep humidity high by covering the tray with plastic wrap.
- Place the tray in a bright, warm location (75 degrees Fahrenheit).
- Transplant seedlings into individual pots once true leaves emerge.
Potting and Repotting
Due to its vigorous growth, stephanotis may need to be repotted every other year to a larger container.
- Choose a container with adequate drainage holes and fill it with half potting soil and half leaf mold or compost.
- Always provide a trellis or support for the vine to climb.
Overwintering
Overwintering is crucial for indoor stephanotis plants:
- Cease humidity efforts and allow the plant’s atmosphere to become dry.
- Water sparingly, only when the soil is completely dry.
- Do not fertilize during the winter.
- Keep the plant in a cool, bright location (50 degrees Fahrenheit).
- Do not prune until late winter or early spring.
Common Pests and Diseases
- Spider mites
- Scale
- Root-knot nematodes
- Aphids
- Mealybugs
- Thrips
- Root rot
- Sooty mold
Bloom Cycle
- Stephanotis typically blooms from late spring to early summer, with occasional blooms in October and November.
- The flowers are small, trumpet-shaped, and pure white, with a sweet, perfume-like fragrance.
- Blooms last longest when left on the vine.
Encouraging More Blooms
- Provide consistent temperatures around 80-85 degrees Fahrenheit.
- Offer afternoon shade to protect flowers from scorching.
- Ensure adequate fertilization and humidity.
- Winter is typically a rest phase, but indoor plants can be encouraged to flower by providing 4-6 hours of light.
Common Problems
- Dropping Flowers and Leaves: Extreme temperature changes or watering issues.
- Patches on Leaves or Stems: Pests such as mealybugs or aphids.
- Yellow Leaves: Nutrient deficiency.
- No Buds or Flowers: Low humidity, insufficient fertilizer, poor winterizing.
