How To Fill Tall Outdoor Planters

Tall outdoor planters are beautiful and striking, creating instant impact in any outdoor space. However, filling them with soil can be a daunting task, especially if you have limited time or experience. Here's a comprehensive guide to help you fill tall outdoor planters like a pro.

1. Choose the Right Soil

The type of soil you use is crucial for the success of your plants. Tall planters need well-draining soil that will allow excess water to escape quickly. Avoid using standard garden soil, which can become compacted and lead to root rot. Instead, opt for a potting mix specifically designed for containers, such as a peat-based mix or a soilless mix.

2. Create a Drainage Layer

Adequate drainage is essential to prevent waterlogging and root problems. Start by placing a layer of gravel, small stones, or broken pieces of pottery at the bottom of the planter. This layer will help create air pockets and allow water to drain away from the roots.

3. Install a Drain Hole or Filter

If your planter doesn't have a built-in drain hole, consider creating one. Drill a hole in the bottom of the planter and insert a piece of plastic mesh or filter fabric to prevent soil from escaping. This will allow excess water to drain out.

4. Fill the Lower Half with Lightweight Material

To minimize the weight and reduce the amount of soil needed, filling the lower half of the planter with lightweight material is advised. Use materials such as expanded clay pebbles, packing peanuts, or plastic bottles with their bottoms cut off. This will provide support for the soil and aid in drainage.

5. Add a Layer of Organic Matter

Before filling with potting mix, add a layer of organic matter such as compost, peat moss, or composted manure. This will provide nutrients and improve soil structure, promoting healthy plant growth.

6. Top Up with Potting Mix

Fill the remaining space with the well-draining potting mix. Avoid compacting the soil excessively, as this can hinder root development and drainage. However, ensure the soil is firm enough to support the plants.

7. Leave Some Headspace

Don't fill the planter to the brim. Leave a gap of about 1 to 2 inches between the soil surface and the top edge of the planter. This will allow for watering without spillage and give the plants room to grow.

8. Water Thoroughly

After filling the planter, water it thoroughly. Soak the soil until water drains out of the drain hole. This will help settle the soil and remove any air pockets.

9. Add a Top Dressing

Consider adding a layer of organic top dressing, such as mulch or gravel, to the soil surface. This will help retain moisture, suppress weeds, and add a decorative touch to your planter.

Conclusion

Filling tall outdoor planters may seem overwhelming, but it's a straightforward task with the right approach. By following these steps, you can create beautiful and thriving displays that will enhance your outdoor space for seasons to come. Remember to choose appropriate soil, create drainage, add lightweight material, and top up with potting mix, leaving sufficient headspace for watering and growth.
