How Do You Grow Senecio Rowleyanus From Seed?
Senecio Rowleyanus can be grown from seed and leaf, however, it is difficult and not advised. The majority of the leaves die, and only a few seeds germinate. The good news is that String of Pearls may be grown simply from cuttings.
The seeds should not be allowed to dry out after being planted directly into the succulent potting mix. If you don’t have time to water every day, place a plastic bag over the pot/tray and tie a knot to keep the potting mix moist. When propagating by leaf, use a succulent cactus mix that has low water retention.
Once the leaves begin to die, cut them from the plant and let them dry for at least two weeks. It is important not to cut them from the stem, or the leaves will wilt.
You may want to use an antifungal solution during this time to prevent fungus from developing on the cutting. When propagating your Senecio Rowleyanus by cutting flowers or stems, you must allow at least two weeks for water loss for new plants to form.
String of Pearls may also be propagated by layering with a long-handled paintbrush or tape measure. You should allow a few weeks for the cutting to develop roots and “calluses” on the bottom before you start watering. Once this occurs, place it into a deeper succulent potting mix and continue watering regularly. The following are the procedures on how to grow Senecio Rowleyanus from seeds:
- Use a sieve or clean paintbrush to remove all foreign matter and dust from the seeds. Try to remove as much chaff as possible.
- Fill a large container with a temperature of 70-80°F (21-27°C). You can add more water than usual since the seeds require some humidity to germinate well. Add two tablespoons of cottonseed meal and half a tablespoon of superphosphate for every bushel of potting mix.
- Add the String of Pearls seeds to the potting mix.
- Cover the seeds with a loose layer of potting soil. Be careful not to add more soil to the pot than what is needed. You must create an adequate amount of moisture for germination. Water regularly so that their soil remains moist but not soggy or damp for about 6 weeks until new leaves appear. Keep them in a warm place (60-70°F/16-21°C) and away from direct sunlight, as frost may damage them before they have established themselves sufficiently.
- After 6 weeks, check the seeds to ensure that they have germinated. You should see roots starting to form on the bottom of the pot where most of the leaf and stem material had been removed. If so, you can remove the plastic bag and allow them to begin growing in their new pots.
- When all seedlings have germinated, water them generously with nutrient-rich water like Epson or Miracle-Gro’s plant food. This will infuse new leaves, stems, and blooms for a beautiful display all season long. String of Pearls can be propagated by leaf in a cactus soil mix as long as it has low moisture retention/drying capabilities.
- The first leaves that form should be the newest growth. Allow them to continue to grow until their new succulent leaves are about 1-2 inches long. This is a sign that you are ready to transplant. You can either move the seedlings into two or more containers or be transplanted individually into larger containers.
How Fast Does Senecio Rowleyanus Grow?
With proper care, Senecio Rowleyanus can grow up to one inch (2.5cm) every month during the warmer months. Because they are succulents, they will grow swiftly, especially in the spring and summer growing seasons, and if provided the proper maintenance circumstances.
