Native to the Cape Province of South Africa where they grow in Sheltered Places.
The species was first introduced into Holland in 1700 and into England in 1774.
There are many different commercial cultivars. They vary in foliage color , size , variegation , bloom color and growth habits.
These are easy plants to propagate from stem cuttings , They should be 3 to 4 inches long . Strip off the lower leaves to facilitate sticking the cutting in the rooting medium.
Perlite , Sharp Sand , and Peat Moss mixed in equal proportions is an ideal medium.
Stick the cuttings an inch deep in the medium and water thoroughly.
Place the container in an area that gets good indirect light. [a North or east facing window]
Rooting occurs best with soil temperatures at 72 to 75 degrees F.
This generally takes three to four weeks. During the rooting period water sparingly.
The trick to successful rooting is to run the cuttings on the dry side.
When the cuttings are rooted place them in 3 or 4 inch containers .
After they have become established , which takes about a week or two , start fertilizing with a liquid fertilizer such as 15-30-15 at half the recommended rate of application. Feed every two weeks during the growing season.
Ivy Geraniums are unique in the cultural requirements and should not be treated the same as common zonal Geraniums.
Light and temperature are two factors that should be considered.
Ivy Geraniums prefer moderate Temperatures . If the temperatures are between 65 and 80 degrees F, place them in full sun.
When the temperatures are above 85 degrees F, hang them in a location that receives morning sun and afternoon Shade.
When in doubt plant them in an area that receives afternoon shade.
Ivy Geraniums require moderate soil moisture levels not too much nor too little.
One of the major problems seen on Ivy Geraniums is edema , a physiological disorder caused by inconsistent moisture levels.
It is characterized by many corky spots of varying size on the underside of the leaves. The stress caused by too little or too much water leads to ruptured plant cells and the formation of scar tissue or corky spots on the underside of the leaf.
Ivy Geraniums are relatively pest free .
The primary pests are,,, mealalybugs , red spider mites , and thrips , all can be dealt with rather easily with the Bayer Advanced Garden Product Tree and Shrub Insect Control. It is a systemic and very safe to use.
