Ticks in the Garden: Which Plants Indirectly Encourage Them

With the first warm days, people, children and pets return to the garden. At the same time, tick season begins. These parasites are no longer found only in woodland; they may be waiting just outside the house. Certain parts of the garden can be especially attractive to ticks, and some plants play an indirect but important part.

Ticks do not favour plants – they favour the conditions beneath them

A common misconception is: “This particular plant attracts ticks.” Experts are clear that ticks are not interested in individual flowers or shrubs, but in the microclimate created by the planting.

What matters to ticks is a cool, damp, shaded habitat – not the type of plant growing there.

Research from universities including Cornell and Texas A&M consistently shows that ticks are particularly common in areas with dense vegetation. Plants in these spots retain humidity, reduce airflow and provide shade. These are precisely the conditions that prevent the small arachnids from drying out.

Typical tick hotspots in the garden

A critical walk around the garden will usually reveal several familiar risk areas:

• dense hedges and groups of shrubs with little air circulation
• tall, uncut grass beside fences or walls
• carpets of ground cover, such as ivy or dense periwinkle
• piles of leaves beneath trees or in corners “that nobody sees”
• stacks of wood in damp, shady recesses

Mice, hedgehogs and other small mammals also commonly travel through these features. They are ideal host animals on which ticks can obtain a blood meal. This creates a kind of hidden tick network within the garden.

These plants can encourage ticks – indirectly

To be clear once again: no plant releases a particular scent that draws ticks in. The concern is with plant types and planting styles that grow very densely, dry out poorly and allow little light to reach the ground.

Ground cover that becomes a tick hiding place

Ground-cover plants are popular because they cover bare areas and require little maintenance. However, when they become overly dense, those same qualities can create a problem:

• Ivy: forms thick carpets that remain cool and damp underneath for a long time.
• Periwinkle and cotoneaster: create closed mats that sunlight can barely penetrate.
• Dense cushion-forming perennials: may look attractive, but trap leaves and moisture within their growth.

Within these plant carpets, ticks position themselves on blades of grass or slender stems, waiting for their next host: a dog, cat or person.

Shrubs, hedges and tall ornamental grasses

Many well-liked garden plants can also become an issue if they are left dense and unmaintained:

• Shrub groups and hedges with dense growth underneath block both wind and sunlight.
• Tall ornamental grasses create shaded, damp areas around their base.
• Untamed corners, where shrubs and grass are simply “left to grow”.

The answer is not to clear everything away. The aim is to let more sunlight and air reach the soil, making the garden less hospitable for ticks.

Simple steps to make your garden less tick-friendly

A few targeted adjustments can substantially reduce the risk of ticks in the garden, without having to remove half the planting.

Maintenance: regular trimming rather than clearing everything

A consistent garden-care routine can achieve a great deal:

• Mow the lawn regularly: Short grass dries more quickly and gives ticks fewer places to cling to.
• Clear away leaves: Especially beneath shrubs, along walls and on paths.
• Thin out shrubs: Remove lower branches so sunlight and air can reach the ground.
• Keep ground cover under control: Reduce its extent, trim the edges and create gaps that admit light.

An open, bright garden is considered far less attractive to ticks than an overgrown, shady haven.

Create barriers against ticks

A buffer zone between a “wild area” and a children’s play or seating area can be useful:

• lay strips of gravel or coarse bark mulch around dense hedges
• define clear boundaries between beds, lawns and patios
• create or widen paths instead of walking straight through tall grass

Ticks are reluctant to cross such dry areas because they dehydrate more quickly there.

Protecting your dog, cat and family

Ticks often do not reach people directly, but arrive via pets or wildlife. Households with animals should therefore establish a few regular habits.

Check after every visit to the garden

After playing or running around outdoors, a quick inspection is worthwhile:

• Run your fingers through a dog’s or cat’s coat, especially around the neck, behind the ears and between the toes.
• On light-coloured fur, look closely as well: ticks resemble small dark lumps.
• If you find one, use a tick card or tick remover and pull it out as close to the animal’s skin as possible.

Veterinary surgeons often recommend spot-on treatments, collars or tablets to prevent ticks. Anyone living in an area with a high tick population should seek advice.

Keep an eye on your own skin

Even after a relaxed evening on a sun lounger, it is worth checking your skin, particularly in common locations:

• behind the knees, around the groin and in the armpits
• on the neck, at the hairline and behind the ears
• around the waistband and in skin folds on the abdomen

Many people use repellents containing ingredients such as DEET, icaridin or oil of lemon eucalyptus for prevention. When walking through tall grass, long trousers tucked into socks remain a straightforward and highly effective barrier.

Health risks: why ticks can cause illness as well as annoyance

Ticks can transmit pathogens, including Lyme disease bacteria and the virus responsible for tick-borne encephalitis (TBE). Not every bite automatically causes an infection, but remaining alert offers protection.

If you find a tick, it is best to remove it within the first few hours, as the transmission risk rises the longer it remains attached. Afterwards, mark or photograph the site and monitor it over the following days. Typical warning signs include:

• a ring-shaped redness around the bite site (erythema migrans)
• unusual tiredness, headaches or fever
• joint or muscle pain with no obvious cause

If these symptoms occur, seek medical advice. In designated risk areas, public health authorities often recommend TBE vaccination.

Greater safety in the garden: practical examples

Making a garden safer from ticks does not require a complete redesign. A clear approach for different zones can help:

Garden zone	Risk	Suitable measure
Children’s play area	medium	Keep grass short; do not place shrubs directly beside the sandpit
Seating area / patio	low	Use a strip of gravel or mulch between planting and the area
Boundary with neighbouring property	high	Thin the hedge, remove leaves and create a path alongside it
Compost area / wood store	high	Do not place it directly beside play areas or routes; keep the ground dry

With only a few changes, this creates a layout that ticks find less appealing while retaining a varied, green garden.

Why ticks seem especially common right now

Many people feel that ticks become active earlier each year and remain around for longer. Increasingly mild winters and damp, warm springs support this trend. Ticks survive frost-free periods more easily, and their active season becomes longer.

For garden owners, this means staying vigilant not only on walks in woodland, but also on the lawn at home. Combining plant choice, garden maintenance and personal protection measures greatly reduces the risk, while still allowing the garden to be enjoyed as a green retreat.
