- Collect the seeds from the mature plant when they are ripe.
- Clean the seeds by removing any debris or non-seed materials.
- Sow the seeds in a seed tray or a pot filled with a mixture of sand and peat moss.
- Keep the soil moist and place the container in a well-lit area.
- Once the seedlings start to grow, you can transplant them to a larger pot or directly into the garden.
Division
Division is another propagation method that can be used for Draba glabella Pursh. This method is typically done in the spring or fall when the plant is dormant. Here's how to do it:
- Carefully dig up the entire plant.
- Gently shake off the excess soil and separate the plant into smaller sections.

- Plant each section in a new location, ensuring that the soil is moist and well-drained.
- Water the newly planted sections thoroughly.
Cutting Propagation
Cutting propagation, while less common, is also a viable way to propagate Draba glabella Pursh. This method is typically done in the summer or early fall. Here's how to do it:
- Select healthy stems from the plant, preferably those that do not have flowers or buds.
- Using a sharp and clean pair of scissors, snip off a 3-4 inch section of the stem.
- Remove the lower leaves of the stem, leaving only a few pairs of leaves at the top.
- Dip the cut end of the stem in a rooting hormone.
- Plant the stem in a pot filled with a mixture of sand and peat moss.
- Keep the soil moist and place the pot in a well-lit area, but avoid direct sunlight.
- Once the stem begins to form roots and new growth, you can transplant it to a larger pot or directly into the garden.
Disease and Pest Management for Draba glabella Pursh
Like all other plants, Draba glabella Pursh is prone to disease and pest infestation. Implementing proper disease and pest management practices is necessary for its healthy growth and sustained productivity.
Common Diseases
One of the most common diseases that affect Draba glabella Pursh is powdery mildew. It appears as a white powdery substance on the plant leaves and stems. To manage powdery mildew, prune out the infected parts of the plant, improve air circulation, and avoid overhead watering as it promotes humidity. Application of neem oil, baking soda, or sulfur-based fungicides can also help control powdery mildew.
Another common disease that affects Draba glabella Pursh is black spot. It appears as black circular spots on the leaves, which eventually causes the leaves to turn yellow and fall off. Effective management of black spot includes removing the infected leaves, improving air circulation, and avoiding overhead watering. Copper-based fungicides may also help control black spot.
Common Pests
Various pests may infest Draba glabella Pursh, including aphids, mealybugs, and spider mites. Aphids easily colonize on plant stems and leaves, sucking plant sap and causing leaf distortion, curling, and yellowing. Mealybugs, on the other hand, typically appear as white powdery spots on plant leaves, stems, and fruit. Spider mites create webbing on the plant leaves and suck plant sap, causing leaf damage and discoloration.
To manage these pests, use a strong stream of water to dislodge them from the plant, physically remove the infested parts, and use insecticidal soap or horticultural oil to suffocate and kill them. However, be sure to follow the instructions on the product label for safe and effective usage.
Regular monitoring, timely intervention, and proper cultural practices can significantly minimize and control disease and pest infestations in Draba glabella Pursh. By implementing these management practices, you can help ensure the plant's healthy growth and sustained productivity.
