Dandelions (Taraxacum spp) can spread quickly via seed to colonise freshly cultivated soil, and are able to survive in compacted soil in lawns. The deep tap root allows them to survive and re-grow when the top of the plant is cut off. Seed can blow in from surrounding gardens, fields and waste-ground.
Clump of leaves growing from a single or multiple point. Leaves and flower stalks ooze a milky substance when snapped. Bright yellow-orange flowers are followed by a fluffy seedhead or dandelion ‘clock’.

Remove the whole tap root by digging down into the soil with a knife or spike-like daisy grubber. Stop plants from setting seed by removing flowers before they produce fluffy seeds.
Dandelions growing in paving or flowerbeds can be treated by applying a systemic weedkiller at the leaves. A selective lawn weedkiller or a lawn feed and weed product can be used on dandelions growing in lawns.
