Propagation of Convolvulus subspathulatus Vatke
Convolvulus subspathulatus Vatke is an annual herb that is typically propagated by seed. It is relatively easy to propagate, requiring only a few basic steps.
Seed Collection
The first step in propagating Convolvulus subspathulatus Vatke is to collect the seeds. The seeds should be collected when they are mature, which is typically in the late summer or early fall. The seeds can be harvested by cutting the seed heads and allowing them to dry completely.
Seed Preparation
Once the seeds have been harvested, they need to be prepared for planting. This typically involves removing the outer coating of the seed, which can help to speed up the germination process. The seeds can be scarified either mechanically or chemically. Mechanical scarification involves scratching the seed coat with sandpaper or a file, while chemical scarification involves soaking the seeds in a solution of water and sulfuric acid.
Planting the Seeds
After the seeds have been prepared, they can be planted directly into the soil. The soil should be well-draining and nutrient-rich. The seeds should be planted about ¼ inch deep and spaced about 6 to 8 inches apart. The seeds should be planted in the spring or early summer, once the soil has warmed up.
Care and Maintenance
Once the seeds have been planted, they will need to be watered regularly until they germinate. After the plants have started to grow, they will need to be watered as needed, typically about once a week. Convolvulus subspathulatus Vatke prefers full sun and well-draining soil, so it is important to plant it in a location that meets these requirements. Once the plants have started to flower, they can be deadheaded to promote additional blooms.
