Fertilization Requirements: Fertilization is usually not necessary for this plant species. However, if planted in low-nutrient soils, slow-release fertilizers can be added once or twice a year. It's important not to overfeed the plant as it can lead to excessive growth and reduced resistance to pests and diseases.
Cultivation methods
Dodonaea viscosa Jacq. subsp. burmanniana (DC.) J.G.West, commonly known as sticky hopbush, is a hardy and drought-resistant shrub that can tolerate a wide range of conditions. It can be grown in full sun to partial shade and prefers well-draining soil with a slightly acidic to neutral pH. The plant can be propagated by seeds or cuttings.
Watering needs
The sticky hopbush is relatively drought-resistant and can tolerate periods of dryness once established. It is important to keep the soil moist during the initial establishment period until the roots are well-established. Afterward, the plant should be watered deeply but infrequently, allowing the soil to partially dry out between waterings. Overwatering can lead to root rot, so it is crucial not to water excessively.
Fertilization
The sticky hopbush does not require much fertilization unless it is grown in poor soil. If necessary, a slow-release fertilizer can be added during the spring growing season. Over-fertilization can lead to excessive growth and reduce the plant's hardiness.
Pruning
The sticky hopbush can be pruned heavily, and this helps to maintain its compact shape and promote bushier growth. Pruning can be done during the winter dormant period or in the early spring before new growth appears. It is essential to use clean and sharp pruning tools to avoid damaging the plant and to prevent the spread of diseases.
Propagation Methods for Dodonaea Viscosa Jacq. subsp. Burmanniana (DC.) J.G.West
Dodonaea viscosa Jacq. subsp. burmanniana (DC.) J.G.West, commonly known as Akeake, is a shrub or small tree that belongs to the family Sapindaceae. It is native to New Zealand and the Southwest Pacific region. It is mostly grown as an ornamental plant and is used for hedging, landscaping, and erosion control due to its hardy nature.
The plant can be propagated through various methods that involve the use of seeds, cuttings, or root division.
Seed Propagation
The plant produces small flowers that develop into capsules containing one or two seeds each. The best time for seed collection is the late summer or early autumn when the capsules turn brown. The capsules need to be dried and stored in a cool, dry place until planting time. The seeds should be sown in a well-draining soil mix, and kept moist but not waterlogged. They can take up to four weeks to germinate.
Cutting Propagation
Akeake can also be propagated through hardwood cuttings. Cuttings should be taken during the winter months from mature wood. They should be about 15-20cm long with at least two nodes and all leaves removed except for a few at the tip. The cuttings are then treated with rooting hormone and planted in a well-draining soil mix. They should be kept warm and moist until roots develop. This can take up to a few months.
Root Division
The plant can also be propagated through root division. This method is usually used to propagate mature plants that have outgrown their space. The roots are carefully dug up, and the plant is divided into equal sections. Each section should have an adequate amount of roots and shoots. The sections are re-planted in well-draining soil mix and watered thoroughly. It can take up to a few months for them to establish.
Overall, Dodonaea viscosa Jacq. subsp. burmanniana is a hardy plant that can be propagated easily through different methods. It is important to maintain the right temperature, moisture, and soil conditions to ensure successful propagation.
Disease and Pest Management for Dodonaea viscosa Jacq. subsp. burmanniana (DC.) J.G.West
Dodonaea viscosa Jacq. subsp. burmanniana (DC.) J.G.West is a relatively hardy plant, but it can still be susceptible to certain pests and diseases. Here are some of the common issues that may affect this plant and some ways to manage them:
Diseases
Leaf spot: Leaf spot is a common fungal disease that affects many plants, including Dodonaea viscosa. It usually manifests as circular or irregularly shaped spots on the leaves, often with a dark center and yellow or brown border. To manage leaf spot, remove affected leaves and debris from around the plant, improve air circulation, and avoid overhead watering. Fungicidal sprays may also be used, but be sure to read the label and follow instructions carefully.
Rust: Rust is another fungal disease that can affect the leaves of Dodonaea viscosa, causing orange or brown spots that may eventually lead to leaf drop. To manage rust, remove infected leaves and debris, and improve air circulation around the plant. Fungicidal sprays may also be helpful.
Root rot: Root rot is a fungal disease that affects the roots of plants, causing them to become brown and mushy. This can often be avoided by providing well-draining soil and avoiding over watering. If root rot is suspected, remove affected plants and soil, and replace with fresh soil and plants.
Pests
Spider mites: Spider mites are tiny pests that feed on the sap of plants, causing leaves to turn yellow and dry out. They are often visible as tiny specks on the underside of leaves. To manage spider mites, spray the plant with a strong stream of water to dislodge the pests, or use insecticidal soap or neem oil. Be sure to follow label instructions carefully.
Aphids: Aphids are another common pest that can affect Dodonaea viscosa. These small insects feed on plant sap and excrete a sticky substance that can attract other pests. To manage aphids, spray the plant with a strong stream of water to remove them, or use insecticidal soap or neem oil. Encouraging beneficial insects, such as ladybugs and lacewings, can also help control aphid populations.
Caterpillars: Caterpillars can feed on the leaves and stems of Dodonaea viscosa, causing holes and damage. Handpicking caterpillars can be an effective way to manage them, or use Bacillus thuringiensis (Bt) if the infestation is severe. Bt is a natural bacteria that is safe for people and pets, but harmful to caterpillars. Be sure to follow label instructions carefully.
By being vigilant and taking steps to manage pests and diseases, you can help keep your Dodonaea viscosa Jacq. subsp. burmanniana (DC.) J.G.West healthy and thriving.
