In brief: Ivy (Hedera helix) is an ecologically valuable climber that provides insects with their last and first source of food in autumn and spring. Its late, nectar-rich flowers feed bees, wasps and butterflies when few other plants are in bloom. Its dense, evergreen growth also offers year-round shelter and nesting sites for birds and small animals.
Ivy in the Garden: A Magnet for Beneficial Insects
Hedera helix, or common ivy, is more than just green wall cover. This robust climber transforms your garden into a vibrant oasis for wildlife. It provides food, shelter and habitat when other plants have long finished flowering.
A nature-friendly garden needs such versatile plants. Ivy structures areas, covers dull corners and performs valuable ecological work at the same time. Its importance for biodiversity is often underestimated.
Why is ivy so valuable for bees?
The flowering period makes all the difference. While the gardening year draws to a close in September, Hedera helix enters its main season. Its small, inconspicuous flower clusters open.
They produce plenty of nectar and pollen. At this time of year, insects can find very few other food sources. Flowering ivy therefore becomes a vital refuelling station.
Honey bees collect its energy-rich nectar for their winter stores. Wild bees, hoverflies and wasps strengthen themselves for the cold season. Late-flying butterflies such as the red admiral also visit the flowers regularly.
Expert tip
Let your ivy flower! Many gardeners cut back the shoots in autumn, depriving insects of their final meal. Wait until after flowering to trim it, ideally in late winter.
Late flowering as a survival aid
Flowering lasts from September into November. On warm autumn days, the plant hums and buzzes with activity. Insect activity is intense.
In early spring, around March, ivy once again serves as a first source of food. Early-flying bumblebee queens and other insects then collect pollen. This dual function makes the plant indispensable.
How does ivy create habitat in the garden?
The flowers are not the only valuable feature. Its dense, evergreen foliage creates a complex microclimate. Many animals find shelter and a place to overwinter among the intertwined shoots.
Birds such as robins, dunnocks and wrens use the thicket as a safe nesting site. In winter, the leaves protect them from frost and predators. Insects such as ladybirds and lacewings like to overwinter in the hollow spaces.
For even better wildlife habitat, combine ivy growth with an insect hotel. This provides additional nesting opportunities for solitary bees and wasps.
An old, flowering ivy on a house wall can support several thousand insects at once on a sunny autumn day. No exotic ornamental plant can match that performance at this time of year.
Ivy as a food plant for butterflies
Hedera helix also feeds caterpillars. The holly blue and the ivy moth lay their eggs exclusively on ivy. The caterpillars feed on its leaves.
By planting ivy, you support the complete life cycle of these species. You create not only a food source for adult insects but also a nursery.
How do I plant and care for ivy correctly?
Ivy is extremely undemanding. It grows in deep shade as well as full sun. The soil should be well drained, as it does not tolerate waterlogging. Plant it in spring or autumn.
Place young plants about 50 centimetres apart. Water them regularly during the first period after planting. Once established, ivy usually manages without additional water.
The right garden tools make the work easier. Sharp shears are essential for pruning.
Important note
Ivy is poisonous in all parts, especially its black berries. Do not plant it within reach of small children or curious pets. It is best to wear gloves when cutting, as the plant sap can cause irritation on sensitive skin.
The right pruning for healthy growth
Pruning controls growth. Shorten excessively long shoots in late winter, before the bird nesting season begins. This prevents the plant from blocking gutters or growing up around windows.
As ground cover, trim the edges regularly to keep the bed tidy.
, the Wonder Shears are a versatile tool for these tasks. They cut cleanly and are gentle on the plant.
Dispose of the cuttings in a garden waste bag. Do not compost them, as the shoots often root again.
What problems can ivy cause?
The biggest problem is its vigorous growth. If left unchecked, ivy can overgrow and smother other plants. On trees, it climbs into the crown and can damage young or weakened trees by blocking out light.
On buildings, the adhesive roots do not penetrate sound masonry. However, where render is already cracked or facade cladding is loose, the shoots can grow into gaps and widen them. Regular checks are key.
Fear of ivy on house walls is often unfounded. Studies show that the growth can even provide protection by shielding the facade from extreme temperature fluctuations and rain. The underlying surface must be sound.
Removing and containing ivy
If you want to remove ivy from a wall, first cut all the shoots close to the ground. Leave the tendrils attached to the wall to dry out. After a few months, they can usually be removed more easily.
Root remnants in the soil must be dug out thoroughly, otherwise the plant will grow back. This work can be laborious where the growth is extensive. Allow enough time.
How can I combine ivy with other plants that attract pollinators?
Ivy works well with other plants. Pair it with early-blooming perennials and shrubs to provide a steady food supply for insects from spring through late fall.
Plant early-blooming bulbs such as crocuses and snowdrops in front of an ivy-covered wall. In summer, lavender, catmint and sage extend the food supply. Find suitable plants and seeds in our Garden + Plant Accessories category.

Complement your ivy with
, Mentzelia Lindleyi (Gold Star) seeds. This annual summer flower has a strong fragrance and provides an excellent food source for bees. It blooms in summer, bridging the gap before ivy flowers in fall.
Creating an ivy hedge
Ivy is ideal for an evergreen, dense privacy hedge. Plant specially selected, fast-growing varieties such as 'Hibernica' in a row, and use a sturdy trellis to support the hedge.
Trim the hedge two to three times a year to keep it dense from top to bottom. An ivy hedge is easier to maintain than many traditional hedge plants and benefits wildlife year-round.

Which ivy varieties are best for insects?
The wild species, Hedera helix, is the most valuable for wildlife. Its flowers produce plenty of nectar. Growers have also developed varieties with especially dense growth or attractive foliage.
'Woerner' is very hardy and produces abundant flowers. 'Goldheart', with its yellow-green variegated leaves, adds bright color and also flowers reliably. Avoid purely ornamental varieties that produce few or no flowers.
Before buying, check the variety's flowering characteristics. Not every ivy sold commercially provides a good food source for bees.
Growing ivy in containers on balconies and patios
No garden? Ivy also thrives in containers. Choose a large pot with good drainage and provide a trellis for support.
Water regularly, since container plants dry out more quickly. In winter, protect the root ball from hard freezes, for example with garden fleece. This helps ivy withstand the cold on a balcony, too.
Container-grown ivy softens the look of building façades and brings wildlife to even small spaces. Pair it with other container plants to create a diverse mini-habitat.
Ivy is a garden classic with enormous ecological value. It offers practical benefits as a privacy screen or ground cover while also supporting biodiversity. With little maintenance, you can create a lively, wildlife-friendly garden that provides year-round habitat for insects and birds. Start with one plant and watch wildlife move in.
Frequently Asked Questions
- When does ivy bloom, and which insects does it attract?
- Hedera helix blooms from September to November. Its subtle yellow-green flower clusters are one of the last nectar sources of the year. They attract honey bees, wild bees, wasps, hoverflies and late-flying butterflies such as the red admiral.
- Is ivy poisonous to children and pets?
- Yes. All parts of ivy are poisonous, especially the black berries, which contain saponins. If children or pets eat the leaves or berries, they may experience nausea and vomiting. Plant ivy out of reach or choose a nontoxic alternative.
- Does ivy damage house walls or masonry?
- Ivy does not damage sound masonry or healthy tree bark. Its aerial rootlets simply cling firmly to the surface. Problems can arise with cracked stucco or rotting wood, where shoots can grow into cavities and trap moisture. Check its growth regularly.
- How can I use ivy for privacy or as ground cover?
- For an evergreen privacy screen, train ivy on a sturdy trellis against the wall. For ground cover, plant 5-7 plants per square metre. Trim the shoots regularly to create a dense, compact mat and keep ivy from climbing where you don't want it.
- How do I care for ivy in the garden?
- Ivy is easy to care for. It grows in shade or sun in ordinary garden soil. Water young plants only during dry spells. Prune in late winter or spring to keep the plant in shape. Fertilizer is rarely needed; a layer of compost in spring is enough.
