Light Requirements:
The Convolvulus nyctagineus Greene, also known as the night blooming wild potato vine, prefers full sunlight. This means that it requires at least six hours of direct sunlight every day to grow and develop properly. It's ideal for growing in hot and dry conditions, making it perfect for regions with long and hot summers.
Temperature Requirements:
The Convolvulus nyctagineus Greene plant can handle a wide range of temperatures. It can grow in temperatures as low as 20°F (-6.7°C) as long as it's protected from frost. However, this vine thrives in warm temperatures, between 65°F (18.3°C) and 80°F (26.7°C).
Soil Requirements:
The Convolvulus nyctagineus Greene grows best in well-drained and slightly acidic soils. It can tolerate poor soil conditions, but it will not thrive in them. This plant prefers to grow in soil with a pH range of 6.5 to 7.5. Sandy or rocky soil types are also suitable because they allow for good drainage, which is essential for the plant's health. It's important to keep the soil moist, but not flooded, and to water it regularly, particularly during dry periods. Fertilizing the soil every two weeks with a balanced fertilizer, particularly one high in phosphorus, will help to promote healthy growth and blooming.
Cultivation Methods for Convolvulus Nyctagineus Greene
Convolvulus Nyctagineus Greene, also known as the pinkie, prefers warm weather and needs full sun exposure. The plant requires well-draining soil, which is slightly sandy or gritty. Planting should be done outdoors after the last frost, and the soil temperature should be at 60°F or higher.
Convolvulus Nyctagineus Greene will bloom continuously from spring to early fall. The pinkie grows well when planted in a garden bed or prefers large pots or hanging baskets on patios.
Watering Needs for Convolvulus Nyctagineus Greene
Convolvulus Nyctagineus Greene needs watering regularly, especially during the warm season. However, it doesn’t perform well in waterlogged areas, and over-watering will lead to root rot. It is advisable to water the soil at the base of the plant, not the foliage, to prevent leaves from developing mildew.
It is good practice to ensure the soil is evenly moist, and the top layer is dry before watering again. During winter, it’s necessary to cut back watering as the plant goes dormant, and the soil dries out slower.
Fertilization for Convolvulus Nyctagineus Greene
Convolvulus Nyctagineus Greene is a low maintenance plant and requires minimal fertilization. Applying fertilizer once a month during the growing season will enhance the plant’s growth and flowering. It is recommended to use a slow-release fertilizer with equal amounts of nitrogen, phosphorus, and potassium. Avoid overfertilizing the plant, which may result in excessive green foliage at the expense of flowering.
Pruning of Convolvulus Nyctagineus Greene
Convolvulus Nyctagineus Greene does not require regular pruning. However, it is advisable to remove dead, damaged, or diseased stems and leaves. Removing spent flowers will encourage more blooms to grow. Trimming the plant's growth towards the end of the summer season will help to keep its shape and form for next year's growth. It is necessary to wear gloves when pruning as the plant's sap may irritate the skin.
Propagation of Convolvulus nyctagineus Greene
Convolvulus nyctagineus Greene, commonly known as night blooming wild sweet potato, can be propagated through several methods:
1. Seed Propagation
Seeds of Convolvulus nyctagineus Greene can be sown in pots or directly in the ground. Seeds should be planted in early spring after the last frost. The soil should be well-drained and moist. Seeds should be sown about 1/4 inch deep and 12 inches apart. Seedlings should emerge within 1-2 weeks.
2. Cutting Propagation
Convolvulus nyctagineus Greene can be propagated through stem cuttings. Cuttings should be taken from mature plants in early summer. The stem should be at least 4 inches long and have at least 2-3 nodes. Remove the leaves from the bottom of the stem and dip the cut end in rooting hormone. Place the cutting in a well-draining potting mix and keep it moist. The cutting should root within 4-6 weeks.
3. Division Propagation
Convolvulus nyctagineus Greene can also be propagated through division. This method is best done in early spring or early fall. Dig up an established plant and separate it into smaller sections. Replant the divisions in well-drained soil and keep the soil moist until new growth appears.
Regardless of the propagation method chosen, Convolvulus nyctagineus Greene prefers full sun and well-drained soil. Proper watering and fertilization will also help ensure successful propagation and growth of this plant.
