Vanilla in the garden: Tips on growing and caring for vanilla orchids at home

Introduction: Vanilla is a coveted spice derived from the fermented pods of the vanilla orchid. Although growing vanilla orchids can be challenging, it is possible to cultivate this exotic plant at home in your own garden or greenhouse. In this blog post, we share tips and advice on how to grow and care for vanilla orchids successfully.

1. Site selection and climate: The vanilla orchid (Vanilla planifolia) thrives best in tropical climates with high humidity and constant temperatures between 20 and 30 degrees Celsius. If you live in a temperate climate, you should consider cultivating your vanilla orchid in a greenhouse or conservatory to ensure the necessary conditions.

2. Substrate and Planters: Vanilla orchids are epiphytes, which means that they

   grow naturally on other plants and get their nutrients from the air and rain. Therefore, they need a well-drained substrate such as orchid bark or coconut fiber to protect their roots from waterlogging. You can plant your vanilla orchid in a special orchid pot or basket with large drainage.

3. Watering and Humidity: Vanilla orchids require high humidity (around 70-80%) and regular watering to thrive. Be sure to keep the substrate evenly moist but not wet to avoid rot and root damage. A good practice is to water the plant thoroughly every few days and allow the water to drain well. To increase humidity, you can use a humidifier or place the plant on a pebble tray filled with water.

4. Light and Temperature: Vanilla orchids need plenty of indirect light to grow well. Direct sunlight should be avoided as it can burn the leaves. A location near an east or west window screened with a translucent curtain would be ideal. During the day, temperatures should be between 20 and 30 degrees Celsius, while at night they can drop to around 15 to 20 degrees Celsius. A drop in temperature at night promotes flowering.

5. Fertilization: Since vanilla orchids naturally receive limited nutrients, it is important to fertilize them regularly. Use a balanced orchid fertilizer (e.g. 20-20-20) and fertilize the plant every two to four weeks during the growing season. You can reduce the fertilization during the resting phase.

6. Growth Support and Pruning: Vanilla orchids are climbers that twine around trees or other structures. Provide your plant with a suitable support, such as a moss stick or trellis, for it to grow up. Prune the plant regularly to encourage healthy growth and keep it in shape. Remove dead or diseased parts of the plant and cut back long shoots to focus the plant's energy on growth and flowering.

7. Flowering and pollination: Vanilla orchids usually only start flowering after three to five years of growth. The flowers are short-lived and only open for one day. In nature, the vanilla orchid is pollinated by a specific species of bee. In your greenhouse or conservatory, you may need to hand pollinate the flowers to encourage vanilla bean formation. Use a fine brush or cotton swab to transfer pollen from one flower to another.

8. Patience and Dedication: Growing vanilla orchids requires patience and dedication as the plants are sensitive to their environment and require constant care. Be patient and adjust care based on your plant's needs to successfully cultivate it and possibly even harvest your own vanilla beans.
