Pruning
Prune the dead or damaged branches to maintain the plant's compact shape. Pinch the tips of the new growth to encourage bushier growth and a continuous bloom.
Remove the spent flowers to promote new blooms and extend the flowering period.
Cut back the plant's growth after the flowering season to promote healthy and vigorous growth during the next growing season.
Propagation of Torenia nana Benth
Torenia nana Benth., also known as dwarf wishbone flower, is a popular ornamental plant commonly used for ground cover, border plantings, and as an underplanting for tall trees. Propagating Torenia nana Benth. is a relatively easy process that can be done through seeds or cuttings.
Propagation by seeds
Torenia nana Benth. produces small, black seeds that can be sown directly in the garden or in seed trays. Here are the steps for propagating Torenia nana Benth. by seeds:
- Collect mature seed from the plant.
- Prepare a seed tray by filling it with a standard potting mix.
- Sow the seed in the tray by sprinkling them over the surface of the soil and covering them lightly with a thin layer of soil.
- Keep the soil moist and place the tray in a bright location out of direct sunlight.
- Germination usually occurs within 2-3 weeks.
- Once the seedlings have developed their first true leaves, they can be transplanted into individual pots or into the garden.
Propagation by cuttings
Propagation of Torenia nana Benth. by cuttings is another option and will produce plants identical to the parent plant. Here are the steps for propagating Torenia nana Benth. by cuttings:
- Select a healthy stem from the parent plant that has not yet bloomed.
- Cut a 2-3 inch section of the stem just below a node (the point where leaves grow from the stem).
- Remove the lower leaves from the stem, leaving only 2-3 leaves at the top.
- Dip the end of the stem in a rooting hormone, which will encourage root growth.
- Prepare a pot with a standard potting mix and make a hole in the center.
- Place the cutting in the hole and firm the soil around it.
- Water the cutting to moisten the soil.
- Cover with a plastic bag to create a mini greenhouse and place in a bright location out of direct sunlight.
- Roots should develop in 2-4 weeks. Once roots have formed, remove the plastic bag and transplant the new plant into a larger pot or the garden.
