Exposure

kolkwitziaThe Chinese Kolkwitzia species prefer sunny or even half-shady locations; they are not afraid of the cold and can be grown in the garden even in areas with a very harsh winter climate. However, the amabilis variety should be treated with care; in fact, it is necessary to protect it from strong winter winds, which could weaken it and compromise its health.

This plant does not present too many problems with the harsh climate, while it suffers more from a long exposure to the sun on hot summer days.

Land

kolkwitzia amabilisThe ideal substratum for the cultivation of the amabilis variety is light, very well drained, rich and soft; before planting the shrub let’s work well the soil of the garden, adding sand, universal soil and a small quantity of organic fertilizer or humus. All this to avoid possible water stagnations which could compromise its health.

Watering

The Kolkwitzia amabilis provides for regular irrigations during the flowering period, but only if the spring is not very rainy, whilst during the rest of the vegetative season we water only sporadically, or in case of prolonged drought and prolonged exposure during the hot summer days. Let’s avoid watering during the cold season. It is advisable, however, to keep the soil moist between one watering and the other.

Multiplication

Kolkwitzia amabilis The multiplication of the Kolkwitzia amabilis can be done by division of the heads in autumn, or in July-August by cutting of the semi-woody branches. From the lateral branches, cuttings of about 25-30 cm are taken, with heel, and planted in a mixture of peat and sand. When the cuttings have rooted, they are transplanted in nursery in April-May of the following year and are cultivated for more than one year for planting them in October, so as to have some small plants with a good resistance.

Kolkwitzia of China – Kolkwitzia amabilis: Pests and diseases

The amabilis species is quite robust, but it can be attacked by fungal diseases if it lives in a humid environment and with water stagnations.

In spring, before the development of the flowering buds, it is advisable to adopt a systemic fungicide treatment, so as to counteract the possible effects of the humid climate; while at the end of winter it is useful to use a broad-spectrum insecticide product to prevent attacks by aphids and parasites; all treatments should always be carried out when there are no flowers in progress.
