How to Plant Tree Ferns in NZ

Tree ferns are a common sight in New Zealand, providing a lush and tropical look to many landscapes. These ferns can grow up to 10 meters tall, making them an impressive addition to any garden or backyard. However, planting tree ferns can be a bit challenging, especially for those who are new to gardening. In this article, we will provide you with a complete guide on how to plant tree ferns in NZ.

1. Choose the Right Location

The location plays a crucial role in the growth and development of tree ferns. These plants prefer shaded and moist areas, making them a perfect fit for areas around water sources like rivers, ponds, and lakes. If you're planting the ferns in your backyard, choose a shaded spot that is sheltered from strong winds. Avoid planting in areas that receive full sun as too much exposure to sunlight can cause scorching on the leaves.

2. Prepare the Soil

Tree ferns prefer well-draining soils that are rich in nutrients. Before planting, ensure that the soil in your chosen spot is of good quality. You can add compost or well-rotted manure to the soil to enrich it with nutrients. The soil should be slightly acidic with a pH level of 5.5 to 6.5. Avoid planting in soils that are waterlogged, as this can cause root rot.

3. Planting the Tree Fern

The ideal time to plant tree ferns is in Spring or Autumn, when the temperatures are mild. Start by digging a hole that is slightly larger than the size of the root ball. Place the tree fern in the hole, ensuring that the top of the root ball is level with the ground. Fill the hole with soil, making sure that the fern is well supported. Gently tamp the soil around the fern to remove air pockets and then water generously.

4. Caring for Your Tree Fern

Once the tree fern is planted, it requires regular care to ensure healthy growth. Water your fern regularly, especially during dry spells, to keep the soil moist. Avoid overwatering as this can lead to root rot. In addition, apply a slow-release fertilizer to the soil during the growing season to promote healthy growth. Prune off any dead or damaged fronds to maintain the plant's health and appearance.

5. Protecting from Frost

Tree ferns can be susceptible to frost damage, especially in areas with harsh climates. If you live in an area prone to frost, wrap your fern in a hessian or fleece material during the winter months to protect it from the cold. Remove the wrapping during the day to allow for ventilation and sunlight.

Conclusion

Planting tree ferns in NZ can be a rewarding experience, but it requires careful planning and attention to detail. By choosing the right location, preparing the soil, planting correctly, and providing regular care, you can enjoy the beauty of these impressive plants for years to come.
