What Can I Use to Fill the Bottom of a Large Planter UK
When it comes to gardening, large planters offer a great way to showcase your favorite plants and flowers. However, filling the bottom of a large planter can be a bit challenging. The purpose of filling the bottom of a planter is to provide proper drainage, prevent soil compaction, and reduce the overall weight of the planter. In this article, we will explore some common and effective materials that you can use to fill the bottom of a large planter in the UK.
1. Polystyrene Chips:
Polystyrene chips, also known as packing peanuts, are a lightweight and affordable option to fill the bottom of a large planter. These chips allow for proper drainage while reducing the overall weight of the planter. Make sure to use only new, clean, and non-biodegradable polystyrene chips to avoid any environmental issues.
2. Gravel or Pebbles:
Using gravel or pebbles as a filler is a classic method that ensures good drainage while adding a decorative touch to your planter. These materials are readily available and come in various sizes and colors, allowing you to customize the look of your planter.
3. Broken Terracotta Pots:
If you have any broken terracotta pots lying around, they can be repurposed to fill the bottom of your large planter. The broken pieces create air pockets, which facilitate drainage and prevent waterlogging. This method is not only effective but also a great way to recycle old pots.
4. Plastic Bottles or Containers:
Plastic bottles or containers can be used as filler material in large planters. Simply fill them with water before placing them in the bottom. This technique not only reduces the overall weight of the planter but also provides a reservoir for water, ensuring your plants stay hydrated.
5. Wood Chips or Bark:
Wood chips or bark are organic materials that can be used to fill the bottom of a large planter. They help improve drainage and retain moisture in the soil. Additionally, they break down slowly, providing nutrients to the plants over time.
6. Vermiculite or Perlite:
Vermiculite and perlite are lightweight, sterile materials that improve drainage and aeration in the soil. They also help retain moisture, making them suitable for large planters. These materials can be mixed with potting soil or used alone as a filler.
7. Styrofoam Blocks:
Styrofoam blocks, similar to polystyrene chips, are lightweight and provide excellent drainage. They can be easily cut to fit the bottom of your planter, leaving room for soil and plants. Ensure that the styrofoam you use is non-biodegradable to avoid any environmental harm.
