Product Information

Full details

The Greena Pentagonal Raised Bed is designed for home gardeners looking to optimize their growing space with a structured, organized planting area. Its primary benefit is the 15 cm elevated design, which simplifies plant maintenance, improves drainage, and creates a clear boundary between crops and the surrounding garden. While it offers excellent versatility for vegetables, herbs, and flowers, users should note that the 15 cm depth is better suited for shallow-rooted plants, and deeper root systems may require additional soil layering or site preparation.

FAQs

What is the total height of this bed?

The Greena Pentagonal Raised Bed is 15 cm high.

Can I use this for root vegetables?

Yes, but due to the 15 cm depth, you should focus on shallower root crops like radishes or short carrots rather than deep-rooting varieties.

Is the wood treated to prevent rot?

The timber is selected for garden use, but we recommend applying a garden-safe wood preservative annually to prolong the life of the wood.

Does the bed come with a base?

No, this is an open-bottom design, which allows for better root penetration and drainage into the ground beneath.

How much soil do I need to fill the bed?

You will need enough soil to fill the internal volume of the pentagonal shape; calculate the area based on the dimensions provided in the assembly guide.

Troubleshooting

Soil leaking through corners

Ensure all connection points are flush and consider using a small piece of landscape fabric on the inside corners to block gaps.

Water pooling around the base

Ensure the bed is placed on a slightly permeable surface or add a layer of gravel underneath the soil to facilitate better drainage.

Setup, Compatibility & Care

To ensure the longevity of your Greena timber bed, follow these steps:

  1. Site Selection: Choose a level spot that receives appropriate sunlight for the plants you intend to grow.
  2. Ground Preparation: Clear the site of grass or weeds. For better weed control, place landscape fabric at the base of the bed before filling.
  3. Assembly: Connect the timber panels according to the instructions to form the pentagonal shape.
  4. Filling: Fill with a high-quality mix of topsoil, compost, and organic matter.
  5. Maintenance: Check the timber periodically for signs of weathering. Depending on the wood finish, you may choose to apply a non-toxic, wood-safe preservative once a year to keep the timber protected from moisture and rot.
