Paulownia tomentosa is commonly known as the Empress Tree or Princess Tree, while the Foxglove Tree is a different species known as Paulownia tomentosa var. tomentosa.
The cultivation and care for the Foxglove Tree, Paulownia tomentosa var. tomentosa, are quite similar to the guidelines provided for Paulownia tomentosa. Here are some additional details specifically for the Foxglove Tree:
- Climate suitability: The Foxglove Tree, like Paulownia tomentosa, is best suited for mild and temperate climates. It requires a frost-free period of at least 200 days for optimal growth.
- Planting: Choose a sunny location with well-drained soil for the Foxglove Tree. It also prefers fertile soil but can tolerate various soil conditions. Follow the same planting instructions as mentioned earlier for Paulownia tomentosa.
- Watering: The Foxglove Tree has moderate water needs. Water it regularly during the first year, especially in dry periods. Once established, it can tolerate short periods of drought. Avoid overwatering.
- Mulching: Apply a layer of organic mulch, such as wood chips or compost, around the base of the tree, while keeping it a few inches away from the trunk. This will help retain moisture, suppress weed growth, and protect the roots during winter.
- Pruning: Regular pruning is necessary to maintain the shape and size of the Foxglove Tree. Prune it during late winter or early spring before new growth emerges. Remove any dead, damaged, or crossing branches. You can also prune to maintain the desired height or shape.
- Fertilization: The Foxglove Tree benefits from regular fertilization. Apply a balanced slow-release fertilizer in spring when new growth starts. Follow the manufacturer’s instructions for the correct dosage and application method.
- Protection from frost: Young Foxglove Trees may be susceptible to frost. Provide protection, such as covering the tree with a frost cloth or using horticultural fleece, in areas prone to late spring frosts.
- Pests and diseases: Similar to Paulownia tomentosa, the Foxglove Tree is relatively resistant to pests and diseases. However, occasional pests like aphids or scale insects and fungal diseases like powdery mildew can affect it. Monitor the tree regularly and take appropriate measures, such as using insecticidal soap or fungicides, if necessary.
- Propagation: The Foxglove Tree can be propagated from seeds or cuttings. Stratify the seeds in the refrigerator for several weeks before planting. Softwood or semi-hardwood cuttings can be taken in early summer and rooted in a well-draining medium.
Remember to check with local authorities before planting the Foxglove Tree, as it may have specific regulations or considerations in your region.
