Oxalis rosea Feuillee ex Jacq. is a low-growing, perennial plant that can spread easily. It is commonly known as Rosy Sorrel and is native to South America. The plant is commonly propagated through seeds, division, and stem cuttings. Here are the methods of propagation:
Seed Propagation
The process of planting seeds is easy and rewarding but can take longer than other propagation methods. Follow these steps:
- Collect ripe seeds from the plant in autumn after flowering.
- Store the seeds in a dry place over winter.
- In early spring, scatter the seeds on moist, well-draining soil.
- Lightly cover the seeds with soil and water.
- Keep them moist and in a warm, bright area until they germinate and develop true leaves.
- Once they grow large enough, transplant the young plants to their permanent location.
Division
Division is the quickest way to propagate this plant. It involves separating the rooted plants into smaller sections. Follow these steps:
- Carefully uproot the mature plant from the soil using a garden fork.
- Gently separate the root ball into two or more sections, ensuring each section has some roots and shoots.
- Plant each section into its new location, ensuring the soil is firm around the roots.
- Water the newly planted sections and keep the soil consistently moist for better growth.
- The best time to divide the Oxalis rosea Feuillee ex Jacq. plant is at the start of the growth season or in early spring.
Stem Cutting
Stem cutting is a common and suitable way to propagate this plant. Follow these steps:
- Select a healthy stem with some leaves.
- Cut the stem right below a node and place it into a pot of suitable rooting medium.
- Keep the soil moist and place the pot in a warm and bright location, protected from direct sunlight.
- The new plant will begin to grow from the node, and this process takes about four weeks.
- The plant can then be transplanted to its permanent location.
No matter which propagation method you choose, with proper care and maintenance, Oxalis rosea Feuillee ex Jacq. can start to develop into a beautiful and cherished plant.
