Known for its rapid growth and large, heart-shaped leaves, this tree can be a standout feature in any garden. Today, I’ll walk you through the steps to successfully plant a Paulownia tree in the UK.
Quick Answer
To plant a Paulownia tree in the UK, choose a sunny spot with well-drained soil, plant in spring, and water regularly during dry periods. Prune to encourage strong growth.
Choosing the Right Location
Paulownia trees thrive in full sun, so choose a spot in your garden that receives at least 6 hours of sunlight a day. In the Midlands, we often have varied weather, so it's important to ensure the site is sheltered from strong winds to protect young saplings.
Preparing the Soil
These trees prefer well-drained soil. If your garden soil is heavy clay, consider raised beds or amend the soil with organic matter to improve drainage. A pH level between 5.5 and 7.0 is ideal, which is typically found in most Midlands gardens.
Planting Your Paulownia Tree
When to Plant
Spring is the best time to plant Paulownia trees. This gives them ample time to establish roots before the winter cold. In Staffordshire, aim for late March to early April when the risk of frost has passed.
How to Plant
- Dig a hole twice the width of the root ball and just as deep.
- Place the tree in the centre of the hole, ensuring the root collar is level with the ground surface.
- Backfill with a mix of soil and organic compost, firming gently as you go to remove air pockets.
- Water thoroughly to settle the soil.
Aftercare and Maintenance
Regular watering is crucial, especially in the first year. During dry spells, aim to water once a week. Mulching around the base can help retain moisture and suppress weeds.
Pruning
Pruning is essential for healthy growth. In the first few years, focus on shaping the tree to maintain a strong, single leader. Remove any competing branches or damaged wood in late winter.

|---|---|---|
| 1 | 1-2 | Regular watering, light pruning |
| 3 | 3-5 | Prune to shape, fertilise in spring |
| 5 | 5-8 | Maintain shape, watch for pests |
