It is drought-tolerant and easy to grow, making it a popular choice for rock gardens, borders, and ground covers. Additionally, the plant has been traditionally used in some cultures as a medicinal herb for treating various ailments, including skin conditions and digestive problems.
Light Requirements
Convolvulus sagittatus Thunb. var. phyllosepalus (Hallier f.) A.Meeuse is a sun-loving plant that thrives in full sunlight. This plant requires a minimum of six to eight hours of direct sunlight daily. Lack of sufficient sunlight results in poor growth and development of the plant.
Soil Requirements
The plant prefers well-drained soil with a pH range of 6.0 to 7.5. It grows well in sandy or loamy soils that are rich in organic matter. Clay soils should be avoided as they hinder proper drainage, which can lead to root rot. For optimal growth and development, the plant requires consistent soil moisture, but care should be taken to avoid waterlogged soils that can damage the roots.
Temperature Requirements
Convolvulus sagittatus Thunb. var. phyllosepalus (Hallier f.) A.Meeuse is a warm-weather plant that thrives in temperatures between 18°C to 30°C. The plant can withstand some frost but is frost-sensitive and cannot tolerate temperatures below -2°C. If grown in areas with cold winters, it is best to grow the plant as an annual or in a heated greenhouse.
Cultivation
Convolvulus sagittatus Thunb. var. phyllosepalus (Hallier f.) A.Meeuse, commonly known as arrowleaf bindweed, is a hardy plant that thrives in hot and dry conditions. It is recommended to cultivate this plant in a location that receives full sun exposure.
The plant grows well in well-drained soil with a pH range between 6.0 and 7.5. It is recommended to till the soil to a depth of 6 to 8 inches before planting.
Propagation is through seeds which should be sown directly in the ground after the last frost date. The seeds should be sown at a depth of approximately 1/8 inch and 6 inches apart.
Watering Needs
Arrowleaf bindweed requires moderate watering. It is recommended to water deeply but infrequently, preferably once every week or two, depending on the weather conditions.
It is essential to avoid overwatering as it can lead to the development of root rot or fungal diseases.
Fertilization
Fertilization is essential for the optimum growth and health of the plant.
It is recommended to fertilize Arrowleaf bindweed during its active growth periods with a balanced fertilizer that contains equal parts of nitrogen, phosphorus, and potassium. Fertilization should be done once every month.
Pruning
Arrowleaf bindweed does not require intensive pruning. However, deadheading the flowers is recommended to encourage the growth of new flowers and to prevent the plant from self-sowing.
Regular inspection is necessary to remove any diseased, damaged, or broken stems. Pinching back the plant when it grows beyond its desired size may also be necessary.
Propagation of Convolvulus sagittatus Thunb. var. phyllosepalus (Hallier f.) A.Meeuse
Convolvulus sagittatus Thunb. var. phyllosepalus (Hallier f.) A.Meeuse is typically propagated by seeds. Here are the steps to successfully propagate this plant through seeds:
- Collect ripe seeds during the fall season.
- Clean the seeds by removing any unwanted material.
- Prepare a potting mix comprising of peat moss and perlite in equal proportions.
- Sow the cleaned seeds on top of the potting mix.
- Cover the seeds with approximately 1 cm of potting mix.
- Water the soil thoroughly.
- Place the pot in a warm location with consistent moisture levels.
- Germination should begin within two to three weeks.
- Once the seedlings grow at least an inch or two, transplant them to their permanent location or a slightly larger container.
Convolvulus sagittatus Thunb. var. phyllosepalus (Hallier f.) A.Meeuse can also be propagated by cuttings. Here are the steps to successfully propagate the plant through cuttings:
- Choose a healthy parent plant and identify the section of the stem that is mature and firm.
- Make a clean cut approximately 6 inches from the tip of the stem.
- Remove all the leaves except for the two or three on the top of the cutting.
- Prepare a potting mix of equal parts peat moss and perlite.
- Make a hole in the potting mix, and insert the cutting into it.
- Water the soil until it is thoroughly moist and place it in a bright location with indirect sunlight.
- A rooting hormone can be applied to increase the chances of root formation.
- Within two to three weeks, the cutting should begin to develop roots and grow new leaves.
- Once the cutting is large enough, it can be transplanted to its permanent location or a larger container.
Disease and Pest Management for Convolvulus sagittatus Thunb. var. phyllosepalus (Hallier f.) A.Meeuse
