Jasmine plants thrive in bright, indirect light. Place your greenhouse in a location that receives at least 6-8 hours of sunlight per day. If natural light is insufficient, you can supplement it with artificial grow lights. Maintain a temperature range of 60-75°F (15-24°C) during the day and slightly cooler temperatures at night.
Jasmine plants prefer high humidity levels. To increase humidity in the greenhouse, you can use a humidifier or place trays filled with water near the plants. Misting the leaves with water regularly also helps to maintain adequate humidity.
Proper watering is crucial for jasmine plants. Keep the soil consistently moist but not waterlogged. Water the plants thoroughly whenever the top inch of soil feels dry. Avoid overwatering as it can lead to root rot. Ensure good drainage in the pots to prevent waterlogging.
Feed your jasmine plants with a balanced, water-soluble fertilizer every 2-4 weeks during the growing season (spring and summer). Use a fertilizer specifically formulated for flowering plants and follow the package instructions for application rates. Avoid fertilizing during the dormant period (fall and winter).
Regular pruning helps maintain the shape and size of jasmine plants. Prune after the blooming period to remove any dead or diseased branches. Trim back long, leggy stems to encourage bushier growth. Pinch off the tips of young shoots to promote branching. Pruning also helps improve air circulation within the greenhouse.
Jasmine plants are climbers and require support to grow vertically. Install trellises or stakes in the pots to provide support for the vines. Gently tie the stems to the support structure using soft plant ties or twine. Regularly check the ties and adjust them as the plant grows to prevent damage.
Monitor your jasmine plants regularly for common greenhouse pests such as aphids, spider mites, and whiteflies. If you notice any infestation, take immediate action to control it. Use organic insecticidal soaps or neem oil to treat the affected plants. Quarantine any heavily infested plants to prevent the spread of pests to other plants in the greenhouse.
Preventive measures can help keep jasmine plants healthy and disease-free. Ensure good air circulation within the greenhouse by spacing the plants adequately. Avoid overhead watering, as it can promote fungal diseases. Remove any fallen leaves or debris from the greenhouse floor to prevent the buildup of pathogens.
As jasmine plants grow, they may outgrow their pots. Repotting is necessary to provide them with fresh soil and room for root expansion. Repot the plants in spring or early summer using a well-draining potting mix. Choose a pot that is one size larger than the current one and gently loosen the roots before placing the plant in the new pot.
Jasmine plants go through a dormant period during fall and winter. Reduce watering during this time, allowing the top inch of soil to dry out between waterings. Limit fertilization or stop it altogether during dormancy. Maintain cooler temperatures (50-60°F or 10-15°C) to mimic natural winter conditions.
By following these care guidelines, your jasmine plants will thrive in the greenhouse, providing you with beautiful blooms and a delightful fragrance.
