Cultivation Methods for Blepharis Glauca
Blepharis glauca is a plant that thrives in warm and sunny conditions. It requires a well-drained soil that is rich in organic matter. The plant is drought-tolerant and can withstand high temperatures. Blepharis glauca can be grown outside in zones 8-11 and is commonly grown as a short-lived perennial or biennial.
Watering Needs for Blepharis Glauca
Blepharis glauca requires moderate watering. It is important to water the plant deeply when you do water it to ensure that the water reaches the roots. The plant prefers to be kept slightly dry, and over-watering can lead to root rot. In the winter, the plant can be allowed to dry out completely in between watering.
Fertilization for Blepharis Glauca
Blepharis glauca benefits from periodic fertilization. The plant prefers a slow-release fertilizer that is high in phosphorus. The fertilizer should be applied during the growing season to promote healthy growth and blooming. Too much fertilizer can lead to excessive foliage growth and can decrease the number of blooms.
Pruning for Blepharis Glauca
Blepharis glauca requires minimal pruning. Deadheading spent blooms promotes the growth of new flowers. It is also important to trim back any diseased or damaged foliage to promote healthy growth. In the winter, the plant can be cut back to a few inches above the soil line to promote new growth in the spring.
Propagation of Blepharis glauca (Nees) T.Anderson
Blepharis glauca (Nees) T.Anderson is a perennial herb that can propagate through various methods, including:
Seed Propagation
The easiest and most common way to propagate Blepharis glauca is through seed propagation. The seeds should be collected from mature plants, removed from the pods, and sown in a well-draining soil mix. The soil should be kept moist but not waterlogged, and the seed tray should be placed in a warm, sunny location. Germination usually occurs within 7-10 days, and the seedlings can be transplanted into individual pots once they have two or three true leaves.
Cutting Propagation
Blepharis glauca can be propagated through cuttings. The best time to take cuttings is during the growing season when the plants are actively growing. A 5-6 inch cutting should be taken from the tip of the growing stem, making sure that there are at least two to three leaves on the cutting. The leaves should be removed from the lower half of the cutting to prevent the loss of moisture. The cutting should be dipped in rooting hormone and placed in a well-draining potting mix. The pot should be covered with a plastic bag or a clear plastic lid to maintain humidity and placed in a well-lit, warm location. The cuttings should root within 2-3 weeks.
Division Propagation
Division is another way to propagate Blepharis glauca. Mature plants can be carefully lifted from the soil and divided into smaller clumps, ensuring that each clump has a portion of the roots and several stems. The divided clumps should be immediately replanted in well-draining soil and kept well-watered until new growth appears.
