原文:
Cultivation and Propagation: Easily growing in cultivation. Pelargonium mirabile is in cultivation locally and in botanic gardens. Seeds from ripe fruits germinate freely and new plants can be raised in greenhouses.
It is summer dormant.
Soil: It does best with a mix that has almost no organic material at all. Perlite can be substituted for pumice, but it tends to rise to the surface of the mixture.
Water requirements. Water from early February to late April, then from early August to late November, at a minimum temperature of +14° C. Keep completely dry in summer and rather dry winter, at a minimum temperature of +8° C. Pelargonium cotyledonis in cultivation is usually so overwatered and overfertilized that it is hardly recognizable as the species that it is. Correctly grown, this is a beautiful, compact and dense plant.
Exposure: Light shade or morning sun in summer.
Frost Tolerance: Tender, it needs frost protection. Recommended minimum temperature is 8 °C or even above. Protect from frost.
Reproduction: There are two main ways to propagate members of the genus Pelargonium. Plant seeds any time of the year, but a spring or autumn sowing of seeds is usually most successful. Rooting cuttings of stems is another method. |
