Daisy Bellis perennis
Daisies are perennial weeds and are also known as the common daisy, lawn daisy and bruisewort. The daisy of the most common and recognisable of all lawn weeds. They are easily identified with their their distinct yellow and white flowers.
Daisies spread via short underground runners called rhizomes. They spread forming a low growing, dense mat, that will tolerate regular and close mowing. Once established they will out-compete and smother areas of fine grass.
Daisy leaves are bourne from the centre of the plant in a basal rosette. Typical daisy leaves are rounded or spoon shaped, sometimes with lightly toothed edges and measure between 2 – 4 cm in length. They are usually pale to bright green in colour.
The distinct daisy flowers have yellow centres with white / pinkish petals, typically between 2 – 3 cm in diameter. The flowers open during the day and close again at night. Daisies produce flowers between the months of March and October. However, it is not uncommon for then to flower all year round.
The daisy will thrive in all conditions, especially moist soils that are lacking in nutrients.
A small number of weeds can be removed by hand using a small fork or daisy grubber, taking care to remove all of the roots.
Encourage a healthy coverage of grass with good lawn care practices.
Maintain adequate nutrition with a balanced fertiliser program.
A selective weed killer can be used to control daisies. Aim to treat the weeds when growth is strong for the best results. A single application is usually enough for daisies, in some cases a second application may be needed 6 weeks after the initial treatment.

Tips for successful weed control using selective herbicides
- Treat weeds when growth is strong, this is usually in May and June.
- Don’t mow the lawn 3 days prior and 3 days after the treatment, to allow for maximum uptake of the chemical.
- Spray when the leaf/foliage is dry, as this reduces runoff and allows the chemical to stick to the weed.
