Fertilization

Sutera placida Hilliard benefits from regular fertilization during the growing season. A balanced, all-purpose fertilizer with equal amounts of nitrogen, phosphorus, and potassium is ideal. The fertilizer application should be done every two weeks or as per the fertilizer instructions.

It is important not to apply too much fertilizer as this can damage the roots and burn the foliage. If the plant shows signs of over-fertilization, such as yellowing leaves or slow growth, leach the soil with water immediately.

Pruning

Pruning is an essential aspect of Sutera placida Hilliard's maintenance. Regular pruning promotes bushier growth and enhances the plant's aesthetic appeal. The best time to prune the plant is during the growing season, ideally in early spring or late summer.

To prune Sutera placida Hilliard, use a sharp pair of scissors or pruning shears. Trim off the unhealthy or dead growth, and pinch back the tips of the long stems to promote branching. It is also essential to remove any yellowing or wilted leaves to prevent the spread of fungal diseases.

Propagation of Sutera Placida Hilliard

Sutera placida Hilliard, commonly known as the Bacopa or Waterhyssop, is a trailing or cascading plant that produces small, bright tubular flowers. It is a great choice for gardeners who want to add color to their garden as the plant is known for its vivid and vibrant blooms. Propagation of this plant can be accomplished through various methods including stem cuttings, division, and seed sowing.

Stem Cuttings

Stem cuttings are a popular method for propagating Sutera placida Hilliard. It is best to take stem cuttings from the plant in the spring or summer when it is actively growing. To propagate the plant using stem cuttings:

1. Select a healthy stem from the parent plant.
2. Cut the stem at an angle, just below a node.
3. Remove any leaves from the lower part of the stem, leaving a few on the top part of the cutting.
4. Dip the cutting in rooting hormone powder and plant it in a pot of well-draining soil.
5. Water the soil well and cover the pot with a plastic bag to keep the humidity high around the cutting.
6. Place the pot in a bright, warm area, but avoid direct sunlight.
7. After a few weeks, the cutting should produce roots, and you can remove the plastic bag.

Division

Division is another excellent method to propagate Sutera placida Hilliard. It is an easy method and helps in rejuvenating an old or overgrown plant. Follow the steps below to propagate the plant by division:

1. Carefully remove the plant from its pot or garden bed.
2. Separate the plant into two or more sections depending on the size of the plant.
3. Ensure that each section has some healthy roots and foliage.
4. Plant each section in well-draining soil in a new pot or garden bed.
5. Water the soil immediately and keep the soil moist.

Seed Sowing

Sowing seeds is the least preferred method for propagating Sutera placida Hilliard as it needs a long time to establish new plants. If you plan to propagate Sutera placida Hilliard using seeds, follow the steps below:

1. Collect seeds from the plant after it has finished blooming.
2. Sow the seeds in a seed tray filled with well-draining soil.
3. Press the seeds lightly into the soil and spray some water on them.
4. Cover the tray with a clear plastic bag to retain moisture.
5. Place the tray in a bright area but avoid direct sunlight.
6. After a few weeks, the seeds will germinate, and you can remove the plastic bag.
7. Once the seedlings grow, transplant them into individual pots or a garden bed.
