If you?re looking for a showy annual bloom in the sunny garden or the container, something you can just plant and forget about, try growing Gazanias. This article will help with caring for these plants.
How to Care for Gazania Flowers
Gazania flowers, also known as African daisies or treasure flowers, are heat-loving annuals that are sometimes grown as perennials in warm climates. They grow to about 10 inches in height and form clumps about 12 inches in width. Gazania produces yellow, white, orange and pink flowers beginning in late spring and lasting until the end of summer. Valued for their ease of care, Gazania flowers can add a splash of color to any garden.
Plant gazania flowers during early spring, after the final frost of winter, in a sunny location with little or no shade. Fertilize the soil using a 16-16-16 NPK fertilizer prior to planting to increase fertility. Spread 3 inches of mulch over the planting site, and use a garden tiller to incorporate it into the soil to increase drainage.

Water gazania flowers once per week during spring, summer and fall. Do not allow any standing water to accumulate around the plant or the roots may rot. Reduce the frequency of watering to twice per week during winter if you're growing the plant as a perennial.
Feed gazania flowers with a balanced 10-10-10 NPK water-soluble fertilizer once every two months during spring, summer and fall months. Refer to the directions provided by the manufacturer for proper dosage and application.
Spread a 3-inch layer of mulch over the surface of the soil surrounding gazania flowers. Begin the layer at least 3 inches from the base of the plant to allow room for growth and air circulation. Replenish the layer of mulch as often as necessary throughout the year.

Remove faded or dead gazania blossoms as soon as possible to encourage additional flowers to form throughout the blooming season. Use your fingers to pinch off the flowers as close to the stem as possible to minimize damage to the plant, or snip them off with scissors.
Space gazania flowers at least 8 inches apart to prevent crowding and encourage good air circulation.
Gazania flowers cannot survive temperatures below 25 degrees Fahrenheit, and should be grown as an annual in all regions where temperatures drop this low.
Chopped leaves or grass clippings serve as an ideal mulch for gazania flowers.

When to plant:
Plant outside in mid-late spring after all danger of frost is past.
Where to plant:
Grow in a sunny to lightly shaded site in a container or landscape. Plants will flower best in full sun.
How to plant:
For beds and borders, loosen soil in the planting area 6 to12 inches deep. Work in compost or other organic matter. Remove plant from container and gently tease out roots or slice the root ball in several places if potbound. Dig a hole slightly larger than the root ball. Place the plant in the hole so the top of the root ball is level with the surrounding soil surface. Fill in the hole, tamp down soil around the base and water well. Space 12 inches apart and allow for adequate air circulation.
Plant as above, using a rich, well-draining potting mix. Spacing can be slightly closer when combined with other plants.
Deadhead spent flowers to encourage reblooming, although this is not required for Symphony or Bright Lights series plants. Plants can be cut back by up to half during hot summer weather for a fuller rebloom in late summer and fall. Where they are perennial, plants can be lightly sheared after the last flush of blooms.
For beds and borders, amend soil with compost or other organic matter and make sure there is good drainage. Optimal soil pH is 5-5.5.
Amendments & fertilizer:
Apply an all-purpose water-soluble fertilizer every 2 to 3 weeks according to package instructions. Since containers are watered more often, nutrients will leach out faster, requiring more frequent fertilizing.
Keep soil evenly moist but not soggy. Plants can become somewhat drought-tolerant once established. Overwatering can lead to fungal disease or rot.
Diseases and pests:
When planted in optimal conditions and properly maintained, there are few, if any, problems. Pests include thrips, whitefly, fungus gnats, or aphids. Diseases include verticillium wilt, powdery mildew, botrytis, phytophthora, gray mold, root or stem rot, all of which can be caused by excess watering, high humidity, or poor air circulation.
Deer will leave them alone for the most part, though extreme conditions can result in deer grazing on plants that they wouldn’t otherwise.
