Pelargonium is a flowering plant, available in many colours and is not at all difficult to grow. Most of pelargoniums are hybrids. They are grouped as follows: Regal Pelargonium, Ivy-leaved Pelargonium, Zonal Pelargonium and Scented leaved Pelargonium.
Germination Temperature (°F)
Water freely when dry in Summer, keep very dry in Winter.
Feed every two weeks with high potash fertilizer in Spring and Summer.
Re-pot in Spring in house-plant compost.
Clip pointed ends before sowing and sow in moist compost. Just cover seeds. Not all seeds will show at once, don't discard the seed container until well over the time of germination suggested.
Sow seeds in early Autumn or early Spring. Take cuttings in mid Summer or early Autumn outdoors, early Autumn and early Spring indoors using bottom heat.
Pelargonium needs full sunlight. They become spindly and their leaves turn yellow in slightest shade.
Old plants can be cut down in Autumn and overwintered by keeping them cool and very dry at the roots.
Stand pots outdoors in Summer and pinch out the growing tips to encourage bushiness. Remove dead flowers to prolong the flowering season.
Specimen plants which need a warmer climate zone than you have do well in sheltered, south-facing walls. The wall acts as a solar collector, absorbing heat during the day and releasing it at night, creating a small zone that is warmer than the rest of the garden.
