Propagation of Veronica decussata
Veronica decussata auct. non Ait., commonly known as the Grecian speedwell, is a species of perennial flowering plant.
Propagation by Seeds
One of the most common methods of propagation for Veronica decussata is through seeds. The seeds are easy to collect and can be sown directly into a seedbed or indoor pots. It is recommended to sow the seeds in early spring or late summer. The seeds are small and should be sown on the surface of the soil, as they require light to germinate. Keep the soil moist but not wet until the seedlings emerge, which usually takes about two weeks.
Propagation by Division
Propagation of Veronica decussata can also be done by division, which is the separation of the plant into multiple smaller plants. This method is best done in the spring or fall when the plant is not in its blooming phase. The plant should be dug up carefully, and the roots should be teased apart into smaller plants. Each smaller plant should have a healthy root system and some leaves. Replant the smaller plant into a new location or container immediately, and keep the soil moist until it establishes new roots.
Propagation by Cuttings
Another method of propagation is through cuttings. This can be done in early spring or summer, using young softwood cuttings. Cut a stem from the plant, about 4 inches long, making sure to include some leaves. Remove the leaves from the bottom inch of the cutting, and dip it into rooting hormone. Plant the cutting into a pot filled with a mixture of sand and peat moss, and keep it moist and in a partially shaded area until it roots, which usually takes about three weeks. Once the cutting has rooted, it can be transplanted into the ground or a larger pot.
Disease and Pest Management for Veronica Decussata Auct. non Ait.
