The Gunnera, with its colossal leaves and dramatic presence, is a plant that demands attention. But what if you have a limited space and yearn for this majestic giant? Fear not, for growing Gunnera in a tub is entirely possible, bringing a touch of the tropics to your patio or balcony.
Choosing the Right Tub
The first step in your Gunnera-growing journey is selecting the right container. Gunnera, being a large plant, requires a substantial tub to thrive. Aim for a container with a minimum diameter of 60cm (24 inches) and a depth of at least 45cm (18 inches). Keep in mind that the larger the tub, the better, as it will provide ample space for the plant’s extensive root system and prevent frequent repotting.
The Perfect Soil Mix
Gunnera prefers a rich, moist soil that drains well. A good mix can be created using:
- Compost: Provides essential nutrients and improves soil structure.
- Coco Coir: Offers excellent water retention and aeration.
- Perlite: Ensures proper drainage and prevents compaction.
Mix these components in equal parts to create a soil mix that is both fertile and well-draining.
Planting Your Gunnera
Once you have your chosen tub and soil mix, you can begin planting your Gunnera. Here’s a step-by-step guide:
1. Prepare the Tub: Fill the tub with the prepared soil mix, leaving a few inches of space at the top.
2. Place the Gunnera: Carefully remove the Gunnera from its nursery pot, gently loosening the roots if they are tightly packed.
3. Position the Plant: Place the Gunnera in the center of the tub, ensuring that the crown (where the leaves emerge) is level with the soil surface.
4. Backfill and Water: Fill the remaining space with soil, gently pressing it down around the roots. Water thoroughly to settle the soil and ensure good contact with the roots.
Providing the Right Sunlight
Gunnera thrives in partial shade, particularly in hot climates. Choose a spot that receives dappled sunlight for a few hours each day, avoiding direct, intense sunlight that can scorch the leaves.
Regular Watering and Feeding
Gunnera is a thirsty plant and requires regular watering, especially during hot and dry periods. Keep the soil consistently moist but not waterlogged.
To ensure your Gunnera thrives, fertilize it regularly with a balanced liquid fertilizer during the growing season (spring and summer). Apply the fertilizer every two weeks, following the instructions on the product label.
Winter Care for Your Tubbed Gunnera
Gunnera is a hardy plant that can tolerate light frosts, but in colder climates, it’s essential to protect it during the winter. Here’s how:
1. Protect the Crown: The crown of the Gunnera is the most vulnerable part during winter. Cover it with a thick layer of mulch, such as straw or bark chips, to insulate it from frost.
2. Move the Tub: If you live in a particularly cold area, consider moving the tub to a sheltered location, such as a garage or shed, for the winter.
3. Reduce Watering: During the winter months, reduce watering to a minimum, as the plant will be dormant.
Pruning and Division
Gunnera can grow quite large, so it’s essential to prune it regularly to maintain its shape and size. You can trim off any damaged or overgrown leaves.
If your Gunnera becomes too large for its tub, you can divide it in the spring. This is a great way to propagate new plants and give your existing one a fresh start.
Enjoying the Majesty of Your Tubbed Gunnera
With proper care and attention, your Gunnera will reward you with its magnificent foliage, adding a touch of tropical grandeur to your outdoor space. Its dramatic presence will be a conversation starter, captivating visitors with its unique beauty.
