Few flowers deliver as much instant color as a gerbera daisy. The bold, perfectly round blooms come in nearly every shade except true blue, sit on tall leafless stems, and last for weeks in the garden and even longer in a vase. Good gerbera daisy care isn’t complicated, but it does hinge on a few specifics that trip up new growers – mainly drainage, crown depth, and where you set the plant in relation to the sun. Get those right and you’ll be rewarded with months of flowers from late spring through fall.
Gerbera daisies (Gerbera jamesonii) are native to South Africa and belong to the aster family, which makes them cousins of sunflowers and marigolds. The genus was named for the 18th-century German naturalist Traugott Gerber. They form a tidy 12-inch-wide clump of long, slightly fuzzy leaves, and each 3- to 4-inch flower rises about 6 inches above that foliage on its own bare stem. Plants typically reach 6 to 18 inches tall, and the petals range across yellow, white, pink, red, orange, lavender, and salmon, often bicolored, with a central disk that may match or contrast in anything from soft yellow to near black.
Are Gerbera Daisies Annual or Perennial
Gerbera daisies are tender perennials, which is why you’ll see them sold and treated as annuals across most of the country. They are reliably perennial only in USDA hardiness zones 8 to 10. Gardeners in zone 8 can carry plants over from year to year if the bed is well mulched and the crowns are protected from hard freezes, while gardeners in zones 9 and 10 can grow them outdoors nearly year-round.
In colder regions you have two practical choices: treat the plant as a one-season annual and replace it each spring, or grow it in a container and bring it indoors before the first frost to overwinter. With good conditions a single plant can live two or three years, though many gerberas bought in bloom are simply enjoyed for one season and then composted.
Where to Plant Gerbera Daisies for the Most Blooms
Light is the single biggest factor in how many flowers you get, because the buds form right at the crown and need light reaching the center of the plant. Outdoors, gerberas want at least 6 hours of sun a day, but they dislike intense heat. In hot-summer climates the ideal spot gives them morning sun and afternoon shade, which keeps the foliage from scorching while still fueling bloom production.
Grown as a houseplant, a gerbera needs bright, indirect light near a sunny window – but not pressed against hot glass, which can burn the leaves. Through the short days of winter you may need a grow light to keep an indoor plant happy. Less light always means fewer flowers, so if an established plant stops blooming, light is the first thing to check.
Soil and the All-Important Crown Depth
Gerberas demand sharp drainage. Excess moisture around the roots and crown is the leading cause of failure, leading directly to crown rot and root rot. Plant them in compost-rich, well-drained soil that is slightly acidic, ideally a pH of 5.5 to 6.5. If you garden in heavy clay, skip the in-ground bed entirely and use raised beds, mounds, or containers with a high-quality potting mix instead.
The detail most guides gloss over is crown depth, and getting it wrong slowly kills the plant. The crown is the point where the stems and roots meet the soil, and it must sit at or slightly above soil level – never buried. Set plants 12 to 18 inches apart so air can move freely between them, which also helps prevent foliar disease.
Here is the part to watch over time: gerberas tend to settle into the soil as the seasons pass, and after a year or two the crown can become completely covered, which invites rot. To prevent this, dig, lift, and replant your gerberas periodically, resetting the crown back at the surface. When you mulch with a 2- to 3-inch layer of pine straw or pine bark to conserve moisture and suppress weeds, keep that mulch pulled well back from the crown.
How to Water a Gerbera Daisy
Gerberas like steady, moderate moisture once established, but the crown should be allowed to dry out between waterings. The simplest rule is to water when the top inch of soil feels dry to the touch, then let the pot drain completely so it never sits in a saucer of water. Indoors, during active growth, that usually works out to watering about once or twice a week, tapering off through the cooler, shorter days of winter.
How you water matters as much as how often. Avoid overhead irrigation and keep the leaves and flowers as dry as you can, because wet foliage spreads fungal disease. Water at the base of the plant, and do it early in the day so any splashed leaves dry before nightfall.
Feeding for Strong Color
Gerberas are heavy feeders, and consistent fertilizing is what keeps the color coming all season. Apply a controlled-release fertilizer two or three times during the growing season, or feed with a water-soluble fertilizer every two weeks. Container plants run through nutrients faster and usually need feeding more often.
Gerberas are also prone to iron and manganese deficiencies, especially in pots, so choose a fertilizer or foliar spray that includes those micronutrients. If you’ve fed heavily and your plant is all lush leaves with few flowers, the problem may be too much nitrogen pushing foliage at the expense of blooms – switch to a bloom-focused formula lower in nitrogen.
Deadheading and Pruning
Deadheading is the easiest way to keep a gerbera flowering. As each bloom fades, cut the stalk all the way back to the base of the plant rather than just snipping the flower head, removing it to the next stem, bud, or leaf. This stops the plant from spending energy on seed and redirects it into new buds.
Because bloom production depends on light reaching the crown, also pull off any withered or damaged leaves and thin out excess foliage that shades the center of the plant. A tidy, open crown produces more flowers than a crowded one.
How to Start New Gerbera Daisies
Most gardeners buy gerberas as small transplants, since the plants are slow and a bit fussy from seed – but propagation is straightforward once you have plants going.
- Division: The most reliable method. Dig up a mature plant with multiple crowns and separate them with a clean, sharp knife. Trim off dead roots, old decaying leaves, and about half of the lower mature leaves, then replant immediately and keep moist until re-established. Dividing every two or three years also rejuvenates short-lived plants.
- Side shoots: Lift an established clump and gently shake new plantlets free from the root mass, then pot them up individually.
- Cuttings: Stem cuttings taken after flowering can root in as little as a week.
- Seed: Sow indoors 8 to 12 weeks before your last frost in a soilless mix kept around 70 degrees F. The seeds need light to germinate, so press them onto the surface rather than burying them, and use a humidity dome. Expect germination in 2 to 3 weeks and first blooms 18 to 24 weeks after sowing.
Overwintering Gerbera Daisies Indoors
In zones below 8, the way to keep a gerbera for another year is to overwinter it as a container plant. You can either let it go dormant or treat it as a winter houseplant.
For dormancy, move the pot to a bright, cool spot around 45 to 50 degrees F, water sparingly to keep it barely moist, and stop fertilizing – the plant will rest and resume growth in spring. To keep it actively going instead, set it in a warm room near 70 degrees F with bright, indirect light. Don’t be alarmed if it blooms only sporadically or not at all through winter; flowering picks back up once the days lengthen.
Common Problems and How to Fix Them
Gerberas have no serious pest or disease problems, but a handful of issues come up often enough to know by sight.
Pests. Whiteflies, aphids, thrips, and spider mites are the usual suspects. Neem oil or insecticidal soap controls all of them. Don’t spray when the temperature is above 90 degrees F or in direct sun, since that can burn the leaves, and apply in the late evening to protect pollinators.
Fungal disease. Gray mold (botrytis), powdery mildew, anthracnose, crown rot, and root rot all trace back to too much moisture and poor air circulation. Prevention is the cure: improve drainage, space plants for airflow, water at the base early in the day, and let the soil dry slightly between waterings.
Yellowing leaves. If older leaves yellow but veins stay green, that’s chlorosis, usually from iron deficiency caused by soil that is too alkaline – gerberas struggle to take up iron once the pH climbs above about 6.2. Correct it with a chelated iron foliar spray and bring the pH back into the slightly acidic range. Yellowing that’s uniform and accompanied by mushy stems instead points to overwatering and crown rot, which calls for drier conditions and a check on drainage.
Drooping or bent flower stems. A classic gerbera frustration is the stem kinking and the flower flopping a few inches below the bloom. This comes from disrupted water uptake – the stem loses water faster than the plant can replace it, sometimes because of microbial buildup blocking the stem. In the garden, make sure plants get enough water during hot, dry spells.
No blooms. If the foliage looks healthy but flowers won’t come, the cause is almost always too little light reaching the crown or too much nitrogen. Move the plant somewhere brighter and switch to a lower-nitrogen, bloom-promoting feed.
Getting the Most From Cut Gerberas
One of the best reasons to grow gerberas is that the blooms make superb, long-lasting cut flowers. Cut stems in the morning when the flower is fully open, since gerberas won’t continue opening once cut. Because those tall hollow stems are prone to the same bending in a vase that they show in the garden, support them by using a tall, narrow vase that holds the stems upright, change the water frequently to limit the microbial buildup that blocks water uptake, and recut the stem ends every couple of days. Treated this way, a single gerbera can stay fresh in the vase for a week or more.
With sharp drainage, a crown kept at the surface, the right balance of sun, and regular deadheading and feeding, a gerbera daisy will hand you a steady run of bold, cheerful flowers from late spring well into autumn. Start one in a container this season, keep the crown dry and the light bright, and you’ll quickly see why gerberas are one of the most rewarding flowers a beginner can grow.
