Everything You Need to Know About Buttercups

Buttercups are broadleaf perennial weeds that thrive in damp, compacted, or nutrient-poor soil. Unlike annual weeds, they return year after year if not properly controlled.

They spread both by seeds and creeping roots, which makes them particularly persistent in lawns that are struggling. Because of this, proper lawn care and targeted treatments are key to keeping buttercups under control.

Buttercup vs Creeping Buttercup

It’s important to know the difference between regular buttercups and creeping buttercup, as this affects how you control them.

• Buttercup (common buttercup) grows upright with tall stems and bright yellow flowers. It spreads mainly by seed, so small infestations can often be managed with manual removal or a selective broadleaf weedkiller.
• Creeping buttercup, on the other hand, spreads horizontally through creeping runners, forming dense mats that are harder to remove. For lawns affected by creeping buttercup, targeted treatment with a selective weedkiller such as ProGreen Selective Weedkiller combined with manual removal of runners is usually the most effective approach.

Understanding which type you’re dealing with helps you choose the right method—upright buttercups are easier to control, while creeping buttercup requires more persistence and lawn maintenance.

Knowing how to identify buttercups early makes it easier to control them.

Buttercups typically

• Produce glossy yellow flowers from spring to summer
• Have dark green, lobed leaves
• Grow low to the ground and spread outwards
• Form dense patches over time

They are commonly found in

• Damp, poorly drained lawns
• Compact or thin turf
• Bare or nutrient-poor areas

A common concern is: are buttercups dangerous?

Are buttercups dangerous for dogs?

They can be —like most Ranunculus species, buttercups contain compounds that can irritate the skin, mouth, and digestive system of pets if ingested. They aren’t typically fatal, but it’s best to keep dogs away from infested areas.

Why are buttercups bad for your lawn?

• They compete with grass for nutrients, light, and space
• They thrive in poor soil, indicating underlying lawn issues
• They reduce lawn density and quality
• Creeping buttercup spreads quickly if left unchecked

If you’re asking how to get rid of buttercups in a lawn or how to get rid of buttercups in grass, there are a few effective approaches depending on the size of the infestation.

Manual Removal

• Best for small patches
• Remove the entire root and runners to prevent regrowth
• Works best when soil is moist

Improve Lawn Health

• A healthy, dense lawn naturally outcompetes buttercups. Focus on:
• Regular mowing at the correct height
• Feeding with seasonal fertilisers such as A1 Lawn Spring & Summer Fertiliser or A1 Lawn Autumn & Winter Fertiliser
• Aerating to reduce compaction and improve drainage

Use Selective Weed Control

Buttercups are broadleaf weeds, so they can be treated with selective lawn weedkillers. For creeping buttercup, products like Dicophar are effective for targeting individual plants without harming surrounding grass.

• Apply during active growth in spring or early summer
• Ensure full coverage of leaves for best results
• Repeat treatment may be required for persistent infestations

Lime can indirectly help reduce soil acidity, which makes conditions less favourable for buttercups. Applying lime alongside regular feeding can improve lawn health and indirectly reduce the prevalence of these weeds. However, lime alone will not remove established buttercups.

Buttercups may brighten your lawn with their yellow flowers, but they can quickly become a nuisance if left untreated.

Understanding how to get rid of buttercups in grass, how to control creeping buttercup, and maintaining a healthy lawn is the best approach to keep these weeds under control. By combining manual removal, targeted selective herbicides, and good lawn care practices, you can enjoy a lush, thick, and buttercup-free lawn year after year.

Key points to remember

• Buttercups can be controlled with selective weedkillers or manual removal
• Manual removal requires digging out roots and runners to prevent regrowth
• Apply treatments in spring or early summer when plants are actively growing
• Maintain a healthy, dense lawn to naturally suppress buttercups
• Lime can help improve soil conditions but is not a standalone solution
• Keep pets away from buttercup-infested areas as they can be harmful if ingested
