Godetia quadrivulnera var. davyi prefers full sun to partial shade for optimal growth. It can tolerate partial shade but may produce fewer flowers and become leggy.
Temperature Requirements
The plant prefers moderate temperatures ranging from 60°F to 70°F (15.5°C to 21°C) during the growing season. Extremely high temperatures may cause the plant to wilt and stunt its growth, whereas frost can damage the plant.
Soil Requirements
Godetia quadrivulnera var. davyi prefers a well-draining soil that is nutrient-rich. It can tolerate slightly acidic to slightly alkaline soil with a pH range of 6.0 to 7.5. It thrives in loamy soil types, but can also grow in sandy soils. The soil should retain some moisture, but not become waterlogged.
Cultivation of Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson
Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson is best cultivated in full sun in a well-draining garden soil with a pH of 6.0 to 7.5. The seeds can be sown in the garden bed after the last frost or started indoors four to six weeks before the last frost and then transplanted.
The plant requires enough space, as it grows up to 12 inches tall and 8 inches wide. Planting them 6 to 8 inches apart offers sufficient room for growth and adequate air circulation.
Watering Needs of Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson
The plant requires regular watering to remain hydrated, especially during the warmer months of summer. Watering should be less frequent during the winter months. The soil should be kept moist, but not waterlogged, to prevent root rot.
Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson benefits from deeper watering but should not be left to sit in standing water.
Fertilization of Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson
Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson benefits from feeding with balanced fertilizer once a month during the growing season of spring to summer. The fertilizer should be worked into the topsoil around the plant and watered in well.
The plant should be fertilized in the morning or evening when the temperatures are lower to avoid root burn.
Pruning of Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson
The plants don't need heavy pruning, but deadheading regularly can encourage a longer blooming period and also prevent seed formation. Cutting back the plant's stems should be done in early spring before new growth emerges, usually up to around 2 inches from the soil level.
The plant may also benefit from pinching back the tips of young shoots to encourage branching and more abundant blooming.
Propagation methods for Godetia quadrivulnera (Dougl. ex Lindl.) Spach var. davyi Jepson
Godetia quadrivulnera var. davyi is a highly ornamental annual plant that can be propagated through various methods. Here are the most common methods:
Seed propagation
Seed propagation is the most popular method of propagating Godetia quadrivulnera var. davyi. Seeds can be collected from the parent plant and sown directly into the soil in late spring, when the temperature has warmed up. Alternatively, seeds can be started indoors 6 to 8 weeks prior to transplanting outdoors. The seeds should be planted about 1/8 to 1/4 inch deep in a well-draining soil mix and kept moist until germination occurs.
Division of clumps
In areas where Godetia quadrivulnera var. davyi is grown as a perennial, the plant can be propagated by dividing the clumps. This should be done in spring or early fall, as soon as the new growth begins. Using a sharp, clean knife, the clump should be divided into several sections with healthy roots and shoots. Each section can then be replanted in a sunny, well-draining soil.
Cutting propagation
Propagation of Godetia quadrivulnera var. davyi can also be done through stem cuttings. This is best done in the spring when new growth has started. Choose a healthy stem that is at least 4 to 6 inches long and make a clean cut just below the node. Remove any leaves from the lower half of the stem and dip the cut end into rooting hormone. Plant the cutting in a well-draining soil mix and keep it moist. Roots should start to develop in 2 to 4 weeks.
Disease Management
Godetia quadrivulnera var. davyi is quite resistant to diseases, but in some cases, it can be affected by fungal and bacterial infections. The most common diseases affecting Godetia quadrivulnera var. davyi are:
- Botrytis blight: Also known as gray mold, it causes the flower buds and leaves to become brown and mushy. This disease can be prevented by ensuring the plant has good air circulation and avoiding overhead irrigation.
- Mildew: Powdery mildew appears on the leaves as white powdery patches. This disease is favored by high humidity and can be prevented by ensuring good air circulation and avoiding overcrowding of plants.
- Leaf spot: It causes brown to black spots on the leaves, and it can affect the plant's growth. This disease can be prevented by ensuring good air circulation and avoiding overhead irrigation.
In case of an infection, it's recommended to prune off the affected plant parts and dispose of them far away from the planting area. Applying fungicides can also help prevent and treat fungal infections.
Pest Management
Godetia quadrivulnera var. davyi is also quite resistant to pests. However, it can be affected by a few insects. The common pests that may affect Godetia quadrivulnera var. davyi are:
- Aphids: They are tiny insects that feed on the sap of the plant, causing the leaves to twist and curl. They can be controlled by spraying the plant with a strong water jet or by using insecticidal soap.
- Thrips: They are tiny insects that feed on the flowers and cause discoloration and distortion. They can be controlled by applying insecticides, but make sure that the insecticide is appropriate for use on the plant.
- Spider mites: They are tiny pests that feed on the sap of the plant, causing discoloration and dryness. They can be prevented by ensuring good air circulation and by spraying the plant with water frequently.
It's recommended to inspect the plants regularly for any signs of pests and to take immediate action to prevent and control the infestation. It's important to use pesticides carefully, following the instructions on the label and using appropriate protective equipment.
