Guide to Lawn Weeds
Lawn weeds are wildflowers that grow in the wrong place, they compete with grass for Sunlight, Water, Air and Nutrients. With most of these plants being larger than the grass plant they impact the health and appearance of your lawn. They can overcrowd the grass too, leading to patches of weak, thin, or discoloured grass. Weeds can spread rapidly, overtaking large areas of your lawn and create an unkempt appearance. Some weeds also have deep roots that disrupt the soil structure, which can make your lawn susceptible to erosion and water runoff.
Identifying Common Lawn Weeds
Dandelion (Taraxacum officinale):
Recognisable by their bright yellow flowers and fluffy seed heads, dandelions have deep taproots that make them resilient and hard to remove. If you take to digging them out ensure you remove the entire root system to prevent regrowth.
Buttercup (Ranunculus repens):
Obviously, the distinctive part of the buttercup is the flower; due to its colour most people recognise it. They can be generally found in most lawns however they do like lime rich soils that drain well and they’re often seen in fields where they are allowed to grow wild.
White Clover (Trifolium repens): This low-growing weed has small white flowers. While some appreciate its nitrogen-fixing properties, others find it invasive. Maintaining a healthy, well-fertilised lawn can minimise white clover growth.
