Gazania uniflora


GeneralitŠ°


To the genus gazania uniflora belong some perennial herbaceous species native to southern Africa; in our gardens they are generally grown as annuals. The gazanias form large basal rosettes of glossy leaves, dark green, rounded, glaucous on the lower side; some species have leaves covered with a light down; from late spring to the first colds from the center of the rosette of leaves stand numerous fleshy stems, 15-30 cm high, which bear large single flowers, with a diameter close to ten centimeters, similar to large daisies, white, cream, yellow , red or deep pink, with a golden yellow center and characteristic dark zoning around the center or along the petals. The removal of withered flowers prolongs the flowering of gazania uniflora. On cloudy days and at night the flowers close and sometimes the leaves rise upwards.

Exposure



The plants of gazania uniflora need a lot of light to be able to bloom, therefore they must be placed in full sun or in partial shade, positions excessively shaded can cause plants almost devoid of flowers; they fear the cold and temperatures below freezing bring the plant to certain death, if desired it is possible to make them winter in a cold greenhouse. This plant, to produce abundant blooms, needs to receive many hours of direct light a day and cannot withstand cold temperatures.

Watering



As for the correct supply of water it is good to water regularly the gazania uniflora, checking that the soil maintains a slight humidity between one intervention and the other even if, these plants, can easily withstand periods of drought lasting a few days. In the autumn and during the winter it is good to decisively reduce the water supply.
From March to October it is good to supply fertilizer for flowering plants every 15-20 days, dissolved in the water used for watering.

Ground



To get the best results it is good to put in the home Gazans in sandy soil, very well drained, even poor or with pebbles. The gazania uniflora plants are very suitable for rock gardens; they develop without problems in any terrain, as long as they are not excessively heavy. Locate these plants when the night temperatures are at least 10 ° C, as these plants don't tolerate harsh temperatures.

Multiplication



The multiplication of this plant variety takes place by seed, in late winter, in a warm bed and it is advisable to keep the seedbed in the dark since the light slows down germination; at the end of summer it is possible to practice leaf cuttings, which are then kept in a tempered greenhouse, to be planted the following spring.

Gazania uniflora: Pests and diseases


aphids and mites lurk on flowers and leaves, blatantly ruining them; conditions of poor ventilation and excessive humidity can favor the onset of powdery mildew or gray mold. To effectively combat the presence of parasites it is possible to use commercially available insecticidal products, or to prepare a natural mixture of water and soap from Marseille, in the quantity of a teaspoon of soap for one liter of water, to be sprayed on the specimens affected.
