Cultivation
Lesquerella kingii S. Wats. ssp. diversifolia is a herbaceous flowering plant that is native to western North America. It is found in rocky soils, on hillsides, and in dry washes, so it requires well-draining soil with a pH range of 6.5 to 7.5. The plant prefers full sun but can tolerate partial shade, especially during the hotter months. It can be propagated through seeds or cuttings.
Watering Needs
Lesquerella kingii S. Wats. ssp. diversifolia is drought-tolerant and can survive long periods without water. However, it needs regular watering during the establishment phase and during prolonged dry periods. Water the plant thoroughly, preferably in the early morning or late afternoon, to prevent evaporation and reduce heat stress on the plant. Avoid overwatering the plant, as it can lead to root rot.
Fertilization
Lesquerella kingii S. Wats. ssp. diversifolia grows well in nutrient-poor soils. Therefore, it does not require frequent fertilization. However, applying a balanced slow-release fertilizer, such as a 10-10-10 or 14-14-14, during the growing season can boost the plant's growth and promote blooming. Spread the fertilizer around the plant, avoiding the stem and leaves, and water thoroughly.
Pruning
Pruning Lesquerella kingii S. Wats. ssp. diversifolia is not necessary, as it has a naturally compact shape. However, if you want to maintain a neat appearance, you can trim the plant after blooming. Cut back the stems to the desired length, leaving some foliage on the plant. Avoid cutting into the woody stems, as it can damage the plant and affect its growth.
Propagation of Lesquerella kingii S. Wats. ssp. diversifolia (Greene) Rollins & Shaw
Lesquerella kingii S. Wats. ssp. diversifolia (Greene) Rollins & Shaw, commonly known as Bladderpod, is a short-lived perennial herb that belongs to the Brassicaceae family. The plant is mainly found in the desert regions of North America, where it grows well in well-drained soils with good organic matter content.
Seed Propagation
The most common method of propagating Lesquerella kingii S. Wats. ssp. diversifolia is by using seeds. The plant produces a large number of seeds, which are relatively easy to collect and sow. The seeds are small and should be sown on the soil surface with minimal covering. The optimum temperature for seed germination ranges between 20 and 25°C, and the seeds germinate within 10-14 days.
It is recommended that seedlings be transplanted into larger containers when they have developed two or more true leaves before being transplanted into their permanent location in the garden.
Cutting Propagation
Another method of propagating Lesquerella kingii S. Wats. ssp. diversifolia is by vegetative propagation, specifically stem cutting. It is essential to note that this method is not as successful as seed propagation, and it is more complicated and time-consuming. It involves the preparation of stem cuttings from mature plants in the fall, about two months before the first frost. The cuttings should be about 3-5 inches long and should be dipped in a rooting hormone before being planted in pots. The pots should be kept in a warm and humid environment, with temperatures ranging between 20 and 25°C.
Division Propagation
Division propagation is another method of propagating Lesquerella kingii S. Wats. ssp. diversifolia, but it is rarely used due to the nature of the plant root system. The plant has a deep taproot that makes it difficult to divide without causing damage. However, if division propagation must be done, it is recommended to do so in early spring, when the plant has not started to grow. The plant sections with a significant portion of root attached can be replanted in a container or outdoors in well-drained soil.
