• Use a high-phosphorus fertilizer in the early growing season to encourage flowering.
• Avoid over-fertilizing the plant, especially with nitrogen fertilizers, as it can lead to weak growth and poor plant performance.
• Make sure to water your Lewisia maguirei thoroughly after fertilizing to help the plant absorb nutrients adequately.
• Stop fertilizing in late summer to promote healthy plant dormancy.

Pruning of Lewisia maguirei A. Holmgren

Pruning is an essential aspect of growing and maintaining a Maguire’s lewisia plant. Proper pruning will encourage the plant to grow healthier and produce more flowers. Here are some pruning tips that can help you ensure that your plant remains healthy:

• Deadhead regularly to maintain a neat appearance and promote new blooms. Deadheading involves removing spent flowers from the plant.
• Cut off yellow, limp, or damaged leaves as they appear. This will ensure that the plant remains healthy and disease-free.
• Prune off the spent flowering stems entirely at the end of summer, taking care not to damage healthy foliage. It will encourage a fresh growth of the plant in the following year.
• Cut back leggy or lanky growth in late spring to encourage better branching and fuller growth.
• Remember not to prune Maguire’s lewisia aggressively, as it may lead to shock and cause the plant to struggle in subsequent growing seasons.

Propagation of Lewisia maguirei A. Holmgren

Lewisia maguirei A. Holmgren, commonly known as Maguire's lewisia, is a beautiful plant that belongs to the family Montiaceae. The plant is native to the Western United States and can be found growing in rocky cracks, cliffs, and outcrops. To propagate this plant, there are two methods one can utilize;

Seed Propagation

Propagation of Lewisia maguirei from seeds is an easy and straightforward process. First, one has to collect mature seeds from the plant during the late summer and fall. To ensure purity, one can opt to collect seeds from only one plant. After obtaining the seeds, mix them with a growing medium, which should be well-draining and light soil. One can use perlite, peat moss, or sand to create the growing medium. Nonetheless, it is essential to ensure that the medium is moist before sowing the seeds.

Sow the seeds on the surface of the growing medium and cover them lightly with a little additional medium. Place the planted seeds in an area that receives indirect sunlight and maintain a constant temperature of 21°C. It is vital to ensure that the planting medium does not dry out by misting it daily or covering it with a plastic wrap. The seeds typically germinate within two to four weeks, and once the seedlings are large enough to handle, they can be transplanted into individual pots.

Leaf Cutting Propagation

Leaf cutting is another method one can utilize to propagate Lewisia maguirei. First, one has to remove a healthy leaf cutting from the parent plant. The cutting should be about three inches in length, and it must have a green, plump, and healthy appearance. Afterward, dip the cut end of the leaf into a rooting hormone and plant it in a well-draining and light potting medium. A suitable medium would be a mixture of peat moss, sand, and perlite.

Once potted, place the plant in a warm and humid environment with a temperature of 21-24°C. One can cover the pot with a clear plastic bag to maintain high humidity levels and monitor the plant regularly, misting to keep the soil moist. In about two to three weeks, roots should start to develop, and new growth should emerge. At this point, the plantlets can be transplanted into individual pots and grown under normal conditions.

In conclusion, Lewisia maguirei A. Holmgren is a beautiful plant, and it is essential to propagate it for conservation purposes. While the plant can be challenging to propagate using traditional methods such as division and cutting methods, seed and leaf cutting propagation methods have proven to be reliable for propagating this species.
