Diascia field cultivation

Diascia Link & Otto

Growing diascia in open ground requires the provision of high-quality drainage to prevent root rot and the selection of sunny, wind-sheltered sites with moderately fertile soil.

In the reference 7 varieties crop Twinspur, where this is mentioned in the description.

When cultivated in open ground, diascia is sensitive to excessive soil moisture, so planting sites must be well-drained with added sand. The plant prefers moderately nutritious substrates, as an excess of fertilizer stimulates vegetative growth at the expense of flowering. Optimal solar illumination is a mandatory condition for maintaining ornamental quality.

The plant's fragile stems require protection from strong winds. Planting density ranges from 12 to 30 cm between specimens, depending on varietal characteristics. In the conditions of central regions, the transplant method is recommended to ensure early flowering, and due to the plant's low winter hardiness, they are dug up for indoor storage.

Agrotechnology includes mandatory pruning of shoots after the first wave of flowering to stimulate repeat flowering, which can last until frost. In open ground, there is an increased risk of infection by Botrytis, Phytium, and Rhizoctonia pathogens, as well as damage by slugs due to the inability to fully control moisture levels.
