When to Plant Tree Lilies in the UK

Tree lilies, also known as tall lilies, are a beautiful addition to any garden, with their large and impressive blooms towering over other plants. But when is the best time to plant them in the UK? Here, we’ll go through everything you need to know about planting tree lilies in the UK.

Planting Time

The best time to plant tree lilies in the UK is in the autumn, around September to October. This gives the bulbs enough time to settle and establish their roots before the winter season sets in. If you live in milder areas of the UK, you can also plant them in the spring, around March to April.

It’s important to avoid planting tree lilies during the summer months, especially during heatwaves, as this can cause stress to the bulbs and ultimately affect their growth.

Choosing the Location

Tree lilies thrive in areas that receive plenty of sunshine, but they also require some shade during the hottest part of the day. They prefer well-draining soil and don’t do well in waterlogged soil. If your garden has heavy clay soil, it’s best to amend it with some sand or grit to improve drainage.

Tree lilies also grow very tall, so it’s important to choose a location that is sheltered from strong winds and allows enough space for the plants to grow without getting crowded.

Preparing the Soil

Before planting tree lilies, it’s important to prepare the soil to ensure proper growth and development. Start by removing any weeds and clearing the area of debris. Dig the soil to a depth of at least 12 inches and mix in some organic matter such as compost or well-rotted manure to improve soil fertility.

Planting the Bulbs

When planting tree lilies, it’s important to plant them deep, at a depth of around 6 to 8 inches. Space the bulbs at least 12 inches apart to allow for proper growth and prevent overcrowding.

After planting, water the bulbs thoroughly to help settle the soil around them. Apply a layer of mulch to keep the soil moist and prevent weeds from growing.

Care and Maintenance

Tree lilies require minimal care and maintenance once planted, but regular watering and fertilising can help promote healthy growth and development. Water the plants deeply once a week, especially during dry periods. You can also supplement with fertiliser every few weeks during the growing season.

As the plants grow taller, they may require staking to prevent them from bending or breaking in strong winds. Use bamboo stakes or other sturdy supports to keep the plants upright.

Conclusion

Tree lilies are a stunning addition to any garden and planting them in the UK is relatively easy. Ensure to plant them in the right location and at the right time to ensure their proper growth and development. With a little bit of care and maintenance, you can enjoy the beautiful blooms of tree lilies in your garden for years to come.
