Hedera helix: Care and growing tips for a versatile ivy
Hedera helix, more commonly known as ivy, is a very widespread climbing or creeping plant, appreciated for its persistent foliage and its ease of cultivation. Its different varieties offer a great diversity of leaf shapes and colors.
Interest in terrarium
Ivy is not ideal for growing in a traditional terrarium due to its need for bright light and good air circulation. It can, however, be used in open or larger terrariums, provided that humidity is monitored and it is provided with support for climbing or spreading.
Exposure and temperature
- Light: Ivy adapts to different exposures, from shade to bright light, but it prefers indirect or filtered light. Direct sunlight can burn the leaves, especially in summer.
- Temperature: Ivy is very hardy and tolerates a wide range of temperatures, from -15°C to 30°C . It adapts well to both indoor and outdoor conditions.
Watering
- Moisture: Ivy likes cool, moist soil, but it does not tolerate excess water which can lead to root rot.
- Frequency: Water regularly during the growing season (spring and summer), allowing the soil surface to dry out slightly between waterings. Reduce watering in autumn and winter.
Substrate
- Mix: Ivy adapts to different types of soil, but it prefers a rich, well-drained and slightly chalky soil. You can use a mixture of indoor plant potting soil , garden soil and sand.
- Drainage: Good drainage is essential to prevent waterlogging and root rot.
Fertilizer
- Period: During the growing season (spring and summer), provide a balanced liquid fertilizer for green plants every two weeks.
- Dosage: Dilute the fertilizer halfway to avoid burning the roots.
- Reduction: Reduce or stop fertilizing in the fall and winter.
Repotting
- Frequency: Ivy does not need to be repotted frequently. Repot it only if necessary, every 2-3 years, in spring, in a slightly larger pot.
- Potting Soil: Use fresh, well-drained potting soil for potting.
Multiplication
Ivy is easily propagated by stem cuttings in spring and summer. You can also use the technique of layering or dividing the clumps.
Mistakes to avoid
- Overwatering: Overwatering can lead to root rot and disease development.
- Lack of light: A lack of light can weaken the plant and make its foliage dull.
- Pruning: Excessive pruning can harm the plant and promote the spread of disease.
With its evergreen foliage and ease of cultivation, ivy is the ideal plant to bring a touch of greenery to your interior or exterior. Let yourself be seduced by its versatility and its ability to adapt to all styles of decoration!
Additional Tips
- Pruning: Pruning is important to control the growth of ivy and give it the desired shape. Prune it regularly to prevent it from becoming too invasive.
- Support: If you are using ivy as a climbing plant, provide it with suitable support (trellis, stake, etc.) so that it can cling and grow.
- Maintenance: Clean the leaves regularly with a damp cloth to remove dust and pests.
