Cultivation
Impatiens L.
Growing Impatiens in a restricted volume of soil, where flowering is stimulated by pot tightness. The method requires moisture control, regular pinching of shoots, and annual renewal of plants through cuttings.
In the reference 17 varieties crop Balsam, where this is mentioned in the description.
A key feature for Impatiens is flowering under conditions of limited root space. Using containers that are too spacious leads to excessive vegetative growth at the expense of generative processes. Maintenance includes mandatory pinching and pruning of elongated stems to form a compact bush and prevent the baring of branches.
The plant is sensitive to water balance: excess moisture triggers root rot and manifests as guttation, while drying out the substrate reduces ornamental value. New Guinea hybrids (Impatiens hawkeri) require more aerated substrates and stable temperatures above +13…+15°C, whereas Impatiens walleriana tolerates shade and indoor conditions better.
Due to the natural aging of the bush and a decrease in flowering intensity by the third year of life, Impatiens is most often grown as a seasonal perennial in pot culture. To maintain ornamental properties and varietal characteristics of hybrids, crop renewal through cuttings is practiced annually.
