One of the many cultivars which have been developed from the Ivy Leaf Geraniumpeltatum), ‘Rote Mini Cascade’ (often sold as P. ‘Red Mini Cascade’) is much more compact than the original species and is ideal for use in hanging baskets. There are also pink- and lilac-flowered cultivars called, respectively, P. ‘Rose Mini Cascade’ and P. ‘Lilac Mini Cascade’. Use ‘Rote Mini Cascade’ in small-scale window-boxes, tubs and baskets, where its scale is far more appropriate than that of its parent. The latter can trail to an impressive lm (3ft) or so, compared with a modest 45cm (18in) in one-year-old ‘Cascades’. As all of the Ivy Leaf Geraniums have brittle stems and leaves, they should always be positioned away from any thoroughfares and handled with particular care when watering, feeding or potting.
Keep ‘Rote Mini Cascade’ ticking over during Winter at a temperature of about 13°C (55°F); it can tolerate temperatures to around freezing, and in very mild regions any plants abandoned outdoors may well survive the Winter. In the Summer, provide draught-free ventilation if temperatures exceed 21°C (70°F).
This Pelargonium needs good sunny conditions: flower production will be poor in conditions of limited light. Any plants with variegated leaves should be grown in good, bright, but less-direct light; this may just mean keeping it out of the midday sun.
Regular, thorough watering is essential; basket and window-box plants will dry out rapidly, and the Ivy Leaf Group need more water than other Pelargonium. In Winter, keep resting plants on the dry side, allowing theto dry out between each watering.
This rather fleshy-leaved Pelargonium has no need of any additional humidity; leaf blemishes will result if any moisture is splashed on leaves which are in sunshine.
During the Summer growing period, use a proprietary houseplant food on established plants every 7-10 days: once the flower buds appear, use a high-potash fertilizer and continue feeding weekly until Autumn.
Any plants in continual growth in Winter can be fed monthly with a proprietary houseplant food. Repot this Pelargonium in Spring into a loam-based ‘compost, removing any decayed or dying foliage, and reduce growth by 8cm (3in).
If the plant is destined for a hanging basket, use a peat-based compost to reduce the total weight. Removal of dead blooms is essential if this Pelargonium is to continue to produce flowers throughout the Summer months.
Incurable viral diseases may appear as yellowish rings and streaks on the leaves: burn the affected plants. Viruses are spread by Aphids and other sucking insects, so these should be eradicated before the problem spreads to any other plants
