Temperature Requirements
Convolvulus spithamaeus L. var. pubescens (Gray) Fern. thrives in warm to hot temperatures between 65 and 85 degrees Fahrenheit (18-29°Celsius). It is a heat-tolerant plant and can also cope with occasional droughts and heat spells. However, frost or cold winds can cause damage to the plant, so it is best to avoid planting in areas with cold winters or cold winds.
Soil Requirements
Convolvulus spithamaeus L. var. pubescens (Gray) Fern. requires well-draining, sandy soil with a slightly acidic to neutral pH between 6.0 to 7.5. The ideal soil should contain a good amount of organic matter and be free of heavy clay. It is essential to ensure that the soil is moist but not waterlogged. Overwatering can cause root rot, which can ultimately kill the plant.
Cultivation Methods
Convolvulus spithamaeus L. var. pubescens (Gray) Fern. is typically grown from seeds or cuttings. The plant prefers well-drained soil and full sun to partial shade. It can be planted in garden beds, as a border plant, or in containers. The seeds should be sown in the spring, while the cuttings can be taken in the late summer or early fall.
Watering Needs
The plant requires regular watering, especially during the hot and dry summer months. However, it is important not to overwater the plant, as this can lead to root rot and other issues. It is recommended to moisten the soil thoroughly and allow it to dry out slightly before watering again.
Fertilization
Convolvulus spithamaeus L. var. pubescens (Gray) Fern. benefits from a balanced fertilizer application during the growing season. A slow-release fertilizer can be applied during planting and every six weeks thereafter. Alternatively, liquid fertilizers can be applied every two to three weeks.
Pruning
Deadheading spent flowers can encourage the plant to produce more blooms. Pruning is not necessary for this plant, but it can be useful to keep the plant contained and tidy. If required, pruning can be done after the blooming period in the fall or early spring before new growth appears.
Propagation of Convolvulus spithamaeus L. var. pubescens (Gray) Fern.
Convolvulus spithamaeus L. var. pubescens (Gray) Fern. can be propagated through several methods, including:
Seed Propagation
Seeds of Convolvulus spithamaeus L. var. pubescens (Gray) Fern. can be sown directly into the ground or in a container. The seeds should be sown at a depth of 1 cm and spaced 5-10 cm apart. It is important to keep the soil moist until the seeds germinate, which usually takes 14-21 days. Seed propagation is best done in early spring. The seedlings can be transplanted to their permanent location once they have developed their first true leaves and have reached a height of 5-10 cm.
Cuttings Propagation
Convolvulus spithamaeus L. var. pubescens (Gray) Fern. can be propagated through stem cuttings. The stem cuttings should be taken in early summer from the current year's growth. Cuttings should be 7.5-10 cm in length and should have 3-4 nodes. Remove the leaves from the bottom 2 nodes and dip the base of the cutting in rooting hormone. Place the cutting in a container filled with well-draining soil and water regularly. Within 2-3 weeks, the cutting should develop roots and can be transplanted to their permanent location.
Division Propagation
Convolvulus spithamaeus L. var. pubescens (Gray) Fern. can also be propagated through division. This method is best done in the spring or fall. Divide the plant by digging it up and separating the roots into 2-3 sections. Ensure that each section has a sufficient number of roots and replant the sections immediately. Water thoroughly after planting.
