Throughout the growing season, it is advisable to conduct occasional maintenance pruning to eliminate any damaged, diseased, or overcrowded growth. This process helps maintain good air circulation around the plant, reducing the risk of fungal diseases and ensuring that each stem receives an adequate amount of sunlight. When performing maintenance pruning, always sanitize your pruning tools between cuts to prevent the spread of pathogens.

Propagation

The propagation of Geranium viscosissimum can be achieved through several methods, including division, cuttings, and seed sowing. Each approach offers unique benefits and considerations, allowing you to choose the most suitable method based on your preferences and resources.

Division

Dividing mature Geranium viscosissimum plants is an effective way to propagate the species while rejuvenating the parent plant. Divisions are typically performed in early spring or fall when the plant is dormant or displaying reduced growth. To divide Sticky Purple Geranium, carefully lift the entire plant from the ground and use a sharp, clean tool to separate the root mass into sections, ensuring that each division contains healthy roots and viable shoots. Replant the divisions in prepared soil, water them thoroughly, and provide appropriate care to support their establishment.

Cuttings

Taking stem cuttings from healthy, non-flowering shoots is another propagation method that can yield new plants with genetic traits identical to the parent. Select a vigorous, disease-free stem and use a sharp, sterilized knife or pruners to snip a 4 to 6-inch section just below a node. Remove the lower leaves to expose the nodes, as these are the sites from which roots will emerge. Plant the cuttings in a well-draining rooting medium, such as a mix of perlite and peat moss, and provide bottom heat and consistent moisture to encourage root development. Once the cuttings have established roots, they can be transplanted into individual containers or directly into the garden.

Seed Sowing

Growing Geranium viscosissimum from seeds allows for the introduction of new genetic variations and the potential for selecting desirable traits. To sow seeds, prepare a seed-starting mix that offers good moisture retention and aeration. Sow the seeds on the surface of the medium and lightly press them into the soil, as they require light to germinate. Maintain consistent moisture levels and provide bottom heat, as geranium seeds typically germinate more readily with warmth. Once the seedlings have developed several true leaves, they can be transplanted into individual pots or directly into the garden.
