Marguerite Daisy Care

Size & Growth

Under favorable growing conditions, the Marguerite daisy reaches up to 1’ foot in height with an equal spread.

The plant has a medium growth rate and matures in 1 to 2 years.

The shrubby foliage of the Marguerite daisy is divided with grey-green leaves. Alternate leaves are fleshy and oval to oval-lanceolate in shape.

Each leaf is about 1”- 3” inches long and approximately 1” wide.

Flowering and Fragrance

Marguerite daisy is a long blooming plant and puts on a spectacular show.

The flower color varies based on plant variety. Typically, they produce white flowers along with yellow or pink daisy-like flower heads which look similar to the Shasta daisy.

Marguerite daisy flowers have yellow centers and approximately 2.5” inches in diameter.

The 4 to 30 flowers are born in loose umbrella grapes and very fragrant.

They bloom freely flowering heavily in late spring/early summer until late summer/early fall.

Light & Temperature

The plant is recommended for full sun in USDA Zones (hardiness zone) 9 through 11.

The optimal growing conditions for healthy Marguerite daisy plants are under cooler temperatures.

However, they don’t tolerate temperatures below freezing.

They may stop flowering when summer temperatures rise above 70° degrees Fahrenheit (21° C).

Marguerite daisies love the sun and thrive under full sun in regions with cooler nights.

They also tolerate partial sun, provided all other growing conditions are met properly.

Watering and Feeding

The Marguerite daisy has average watering needs with regular watering during the growing seasons. You may need to increase the frequency during long dry spells.

Be careful about overwatering, as overwatering may have adverse effects.

Too much water around the roots increases the plant’s susceptibility to root rot, mildew, and mold.

Marguerite plants prefer moderate fertility and don’t require frequent feeding in organically-rich soil.

Applications of a well-balanced all-purpose liquid fertilizer once per month in garden beds and potted plants encourage better performance.

Soil & Transplanting

Luckily, the beautiful marguerite daisies are not too fussy when it comes to growing material.

  • They do well in most average gardening soils with good drainage and average fertility.
  • Drainage is important as it prevents the soil from retaining too much water.
  • Before transplanting marguerites, make sure to water the potting mix thoroughly.
  • Dig a hole slightly larger than the previous pot.
  • Gently remove the plant from the pot, tease the roots a little if the plant is root-bound.
  • Place the plant in the hole, making sure the top of the root ball is level with the surface.
  • Fill the gaps and firm down the soil with your hands.
  • Water the soil to let is set.

Grooming and Maintenance

Encourage a compact growth habit of Marguerite daisy by pinching back tips when they begin appearing in early spring.

Most new varieties flower continuously without deadheading.

However, once the bloom period ends deadhead and prune back dying flowers and foliage.

This will promote future flowering and shrubbier growth.

How to Propagate Marguerite Daisy

While propagation with seeds is possible, specific cultivars do not grow true from seeds.

Cuttings and division are the common ways the plant is propagated.

  • If you do use seeds, start them 6 to 8 weeks before planting them outside.
  • Sow the seeds indoors.
  • Maintain a soil temperature of 70° degrees Fahrenheit (21° C) and let it germinate for the next 2 weeks.

Divide Marguerite daisy in spring to mid-summer.

  • Discard the woody parts of the divisions.
  • Plant the remainder in the garden directly.
  • Softwood cuttings are taken from non-flowering shoots in mid-spring or late summer.
  • They should be 2” – 4” inches long.
  • Overwinter them in a greenhouse or treat them to a cold frame with a minimum temperature of 41° degrees Fahrenheit (5° C).

Summer Daisy Pest or Diseases

Most pests don’t plague marguerite plants. However, be on the lookout for usual suspects including aphids, thrips, mites, and leaf miners.

Go online or visit your local garden center for natural pesticides like neem oil.

As for diseases, root rot and crown gall may be occasional problems.
