How To Fill A Large Planter


When it comes to filling a large planter, there are several important steps to consider in order to ensure the optimal growth and health of your plants. By following these guidelines, you can create an ideal environment for your plants to thrive and enhance the beauty of your outdoor space. Here’s a step-by-step guide on how to fill a large planter effectively.

Steps to Fill A Large Planter

1. Choose the Right Planter

Before filling a large planter, it’s essential to select the right container for your plants. Consider the material, size, and drainage options of the planter. Opt for a sturdy and weather-resistant material like ceramic, fiberglass, or metal. Ensure that the planter for snake plants or for other plants has adequate drainage holes to prevent waterlogged soil, which can lead to root rot.

2. Add a Drainage Layer

To facilitate proper drainage, start by adding a layer of drainage material at the bottom of the planter. This can be composed of small rocks, pebbles, or broken pottery pieces. The drainage layer allows excess water to escape, preventing water accumulation and potential damage to the plant roots.


3. Use High-Quality Soil

Choose a premium quality potting soil that is well-draining and nutrient-rich. Avoid using regular garden soil, as it tends to be heavy and may not provide sufficient aeration for container plants. Look for a potting mix specifically formulated for containers, which usually consists of a blend of organic matter, perlite, and vermiculite. Fill the planter about three-fourths full with the potting soil.

4. Incorporate Organic Matter

Enrich the potting soil by adding organic matter such as compost or well-rotted manure. Organic matter improves soil structure, enhances moisture retention, and provides essential nutrients to the plants. Mix the organic matter thoroughly into the potting soil to ensure an even distribution.

5. Plant Your Selections

Now that the planter is partially filled with the prepared soil mixture, it’s time to plant your selections. Choose plants that are suitable for the available light conditions and the size of the planter. Consider the growth habits, colors, and textures of the plants for an aesthetically pleasing arrangement. Dig holes in the soil large enough to accommodate the root balls of the plants. Gently place the plants into the holes and backfill with additional soil, firming it gently around the roots. There are various pot sizes available in the market so before buying them it is important to measure a planter pot.

6. Water Thoroughly

After planting, water the planter thoroughly to settle the soil and provide initial hydration to the plants. Ensure that the water reaches all the way to the bottom of the planter, allowing it to drain freely. This will help the roots establish themselves and prevent air pockets in the soil. Monitor the moisture level of the soil and water accordingly to keep it consistently moist but not waterlogged.

7. Mulch the Surface

Mulching the surface of the soil is an important step in filling a large planter. By applying a layer of organic mulch such as wood chips, straw, or shredded leaves, you can provide numerous benefits to your plants. Mulch acts as a protective barrier, preventing weed growth and conserving moisture in the soil. It also helps regulate the temperature of the soil, keeping it cooler in hot weather and warmer during colder periods.


Filling a large planter requires careful consideration and attention to detail, but the results are well worth the effort. By following the steps outlined in this guide, you can create an optimal environment for your plants to thrive. From choosing the right planter and providing proper drainage to using high-quality soil and incorporating organic matter, each step contributes to the overall health and beauty of your plants.
