Growth Conditions for Convolvulus tubus Schltdl.
Light: Convolvulus tubus Schltdl. thrives in full sunlight. It requires a minimum of 6 hours of direct sunlight per day for optimal growth.
Temperature: The plant is considered heat-tolerant but cannot withstand frost conditions. It grows optimally in warm temperatures between 20°C to 30°C. Lower temperatures around 15°C can cause stunted growth, while temperatures above 35°C can cause flower buds to abort.
Soil: Convolvulus tubus Schltdl. prefers well-draining soils that are slightly acidic to neutral (pH 6.0 to 7.5). It can grow in a wide range of soil types, including loam, sandy loam, and clay loam. However, it cannot tolerate waterlogged soils that can cause root rot.
Fertilizers: The plant does not require excessive fertilizers. A balanced fertilizer with an equal proportion of nitrogen, phosphorus, and potassium can be applied every 4-6 weeks during the growing season.
Water: Convolvulus tubus Schltdl. requires moderate watering. The soil around the plant should be kept moist but not waterlogged. The frequency of watering should be reduced during the winter months.
Humidity: The plant prefers a dry and arid climate. High humidity levels can cause leaf spotting and fungal diseases.
Propagation: Convolvulus tubus Schltdl. can be propagated through seeds or stem cuttings. The seeds should be sown in early spring, while stem cuttings should be collected from non-flowering stems during the growing season.
Cultivation and Care of Convolvulus tubus Schltdl.
Convolvulus tubus Schltdl., commonly known as Bush Morning Glory, is a lovely addition to any garden. It is a low-growing shrub that produces small, funnel-shaped flowers in shades of pink and white. The following tips will help you successfully cultivate and care for this plant.
Cultivation
Convolvulus tubus Schltdl. requires well-draining soil, rich in organic matter. It prefers full sun exposure and requires a warm, dry climate to thrive. This plant is suitable for USDA hardiness zones 9 through 11.
When planting, make sure to keep the root ball level with the soil surface. Avoid planting too deeply, as this can cause root rot and other issues. Water the plant thoroughly after planting and then keep the soil lightly moist until the plant establishes roots.
Watering Needs
Convolvulus tubus Schltdl. is not a high-maintenance plant when it comes to watering. It prefers well-draining soil and does not tolerate waterlogged conditions. Water the plant deeply once a week during the growing season and only when the top inch of soil feels dry to the touch. In the winter, reduce watering to once a month.
Fertilization
Convolvulus tubus Schltdl. benefits from periodic fertilization during its growing season. Apply a low-nitrogen, slow-release fertilizer in early spring and then again in mid-summer. Follow the manufacturer’s instructions for application rates and amounts per plant.
Pruning
Pruning is not necessary for Convolvulus tubus Schltdl. However, you can pinch back the tips of the stems to encourage bushier growth. Removing spent flowers can also extend the plant's blooming period. If necessary, you can prune the plant in early spring to remove any dead or damaged growth.
Propagation of Convolvulus tubus Schltdl.
Convolvulus tubus Schltdl. can be propagated through several methods. The most common propagation methods are seed propagation and vegetative propagation.
Seed Propagation
Seed propagation is the easiest method to propagate Convolvulus tubus Schltdl. Seeds can be collected from the plant's fruit capsules after they have dried out. The seeds should be sown in pots filled with a well-draining potting mix. The pots should be placed in a warm and sunny location. The seeds will germinate in about two weeks, and the seedlings can be transplanted into larger pots or directly into the garden after they have developed a few leaves.
Vegetative Propagation
Vegetative propagation is a more complex method to propagate Convolvulus tubus Schltdl., but it can be more effective than seed propagation. This method involves taking stem cuttings from the plant and rooting them. The cuttings should be about six inches long and taken from the plant's non-flowering stems. The cuttings should be stripped of their lower leaves and planted in a well-draining potting mix. The pots should be kept in a warm and humid location until the cuttings develop roots, which typically takes three to four weeks. The rooted cuttings can be transplanted into larger pots or directly into the garden.
Disease and Pest Management for Convolvulus tubus Schltdl.

Scales
Scales are another common pest that can affect Convolvulus tubus Schltdl. They are small and difficult to detect, but their presence can be indicated by a sticky residue on the leaves and stems. To control scales, remove any weeds around the bushes and prune any heavily infested branches. Insecticidal soaps and horticultural oils can also be used to control scales.
Spider Mites
Spider mites can cause significant damage to Convolvulus tubus Schltdl. by sucking sap from the leaves and causing them to turn yellowish-brown. To prevent spider mite infestation, maintain high humidity around the bushes by watering them regularly. Inspect the bushes for signs of spider mites and spray them with insecticidal soaps or horticultural oils to control the infestation.
In conclusion, Convolvulus tubus Schltdl. can be affected by various diseases and pests, but with the proper preventive measures and timely management techniques, they can be kept healthy and vibrant.
