Hedera, commonly known as ivy, is a popular plant choice for both indoor and outdoor spaces. Its lush green foliage and ability to climb walls or cover the ground make it a versatile and attractive addition to any garden or landscape. However, when it comes to planting hedera, one important consideration is the spacing between each plant.

The appropriate spacing between hedera plants will depend on several factors, including the specific variety of ivy, its growth habit, and the desired outcome for your garden or landscape. Here are some guidelines to help you determine how much space to leave between each hedera plant.

Consider the Growth Habit

Before deciding on the spacing between hedera plants, it’s essential to consider their growth habit. Hedera can have either a creeping or climbing habit, and this will influence how much space they need to grow properly.

If you are planting a creeping ivy variety, such as Hedera helix ‘Glacier’ or ‘Goldchild,’ these plants are typically low-growing and spread across the ground. For this type of ivy, leave about 12 to 18 inches (30 to 45 cm) between each plant. This spacing will allow them enough room to spread and cover the ground effectively.

On the other hand, if you are planting a climbing ivy variety, such as Hedera helix ‘Baltica’ or ‘Thorndale,’ these plants will grow vertically and require support structures like trellises or walls to climb. In this case, you should leave a distance of at least 18 to 24 inches (45 to 60 cm) between each plant. This spacing will give them enough room to grow upwards and attach themselves to their support structure without overcrowding.

Account for Mature Size

Another factor to consider when determining the spacing between hedera plants is their mature size. Different ivy varieties can have varying growth rates and sizes, so you need to account for this to avoid overcrowding in the future.

For instance, if you are planting a fast-growing variety like Hedera helix ‘Needlepoint’ or ‘English Ivy,’ these plants can quickly fill out and become dense. To prevent overcrowding, it is best to leave a larger gap of around 24 to 36 inches (60 to 90 cm) between each plant. This spacing will allow them to reach their full potential without competing for resources or becoming tangled.

On the other hand, if you are planting a slower-growing variety like Hedera helix ‘Sagittifolia’ or ‘Parsley Crested,’ these plants may take longer to reach their mature size. In this case, you can space them closer together, leaving approximately 12 to 18 inches (30 to 45 cm) between each plant.

Desired Outcome

The desired outcome for your garden or landscape will also influence the spacing between hedera plants. If you want a dense and fully covered area, you may choose to plant them closer together. However, keep in mind that this may require more maintenance in terms of pruning and trimming to control their growth and prevent overcrowding.

Alternatively, if you prefer a more open and airy look, you can space hedera plants farther apart. This will allow each plant to have more individual space to grow and will create a visually appealing arrangement with gaps between the foliage.

Overcrowding Consequences

Planting hedera too closely together can result in several negative consequences. Overcrowded plants may compete for resources such as sunlight, water, and nutrients, leading to stunted growth and poor overall health. Additionally, lack of airflow between densely packed hedera plants can increase the risk of diseases, pests, and mold infestations.

Overcrowding can also make it difficult to access and maintain your ivy plants properly. Pruning, trimming, and controlling their growth will become more challenging if the plants are too close together. Therefore, it is crucial to consider the long-term consequences of overcrowding when determining the spacing between hedera plants.

Final Thoughts

Proper spacing between hedera plants is essential for their healthy growth and overall appearance in your garden or landscape. Considering the growth habit, mature size, desired outcome, and potential consequences of overcrowding will help you determine the appropriate distance between each plant.

Remember that these guidelines are general recommendations, and it’s always best to consult specific plant care instructions or seek advice from a horticulturist or gardening professional familiar with hedera varieties. By giving your hedera plants enough space to thrive, you can enjoy their beauty and benefits for years to come.
