How To Fill Large Outdoor Planters

Large outdoor planters are a fantastic way to add a touch of greenery and style to your outdoor space. Whether you're creating a lush focal point on your patio, adding vibrancy to your driveway, or simply wanting to enjoy the beauty of plants, filling these planters effectively can be a rewarding experience. This guide provides a step-by-step approach to filling large outdoor planters, ensuring healthy plant growth and aesthetic appeal.

1. Choosing the Right Plants

The first step to filling large outdoor planters is selecting the right plants. Consider the following factors:

Light Requirements: Determine the amount of sunlight your planter will receive throughout the day. Choose plants that thrive in similar conditions.
Soil Preference: Different plants have varying soil preferences. Research the specific needs of your chosen plants.
Growth Habits: Consider the mature size of the plants and how they will grow in the planter. Choose plants that will complement each other and provide visual interest.
Climate: Select plants that are suitable for your local climate. Some plants are more resilient to heat, cold, or drought.

When selecting plants, consider a mix of textures, colors, and heights for visual interest. A good rule of thumb is to incorporate plants with varying growth habits, such as trailing vines, upright perennials, and low-growing groundcovers. Remember to choose plants that are compatible with each other and will not compete for resources.

2. Preparing the Planter

Before planting, prepare the planter to ensure optimal drainage and plant health.

Drainage Holes: Ensure the planter has sufficient drainage holes at the bottom to prevent waterlogging. If necessary, drill additional holes for better drainage.
Potting Mix: Use a high-quality potting mix specifically designed for outdoor planters. Avoid using garden soil as it can compact and hinder drainage.
Drainage Layer: Add a layer of gravel or broken pottery shards to the bottom of the planter to improve drainage and prevent the potting mix from clogging the holes.

To ensure proper drainage, place a layer of landscape fabric over the drainage layer. This will help to prevent the potting mix from washing out of the planter while allowing water to pass through freely.

3. Planting and Spacing

Once the planter is prepared, you can begin planting your chosen plants.

Spacing: Space the plants according to their mature size, ensuring ample room for growth. Consider the root systems of the plants and allow enough space for them to spread.
Planting Depth: Plant the plants at the same depth they were growing in their original containers. Avoid planting too deeply, as this can restrict root growth.
Firmly Plant: After planting, firmly press the soil around the base of the plants to ensure they are stable.

Place larger plants in the center of the planter and smaller plants around the edges. This will create a balanced and visually appealing composition.

4. Watering and Maintenance

Regular watering and maintenance are crucial for keeping your large outdoor planters healthy and vibrant.

Watering: Water the plants deeply and thoroughly, allowing the water to drain freely. The frequency of watering will depend on the weather conditions and the plants' water requirements.
Fertilizing: Use a balanced fertilizer specifically designed for outdoor plants. Follow the manufacturer's instructions for application rates and frequency.
Deadheading: Regularly remove faded flowers and dead leaves to encourage continued blooming and growth.

As the plants grow, you may need to adjust the spacing or remove any plants that become overcrowded. Monitor the plants for signs of pests or diseases and take appropriate action if necessary.

5. Adding Finishing Touches

To enhance the visual appeal of your large outdoor planters, consider adding finishing touches:

Mulch: Apply a layer of mulch around the base of the plants to retain moisture, suppress weeds, and improve aesthetics. Choose a mulch that complements the overall design of the planter.
Ornamental Elements: Incorporate decorative elements such as rocks, stones, or figurines to create visual interest and texture.
Outdoor Lighting: Consider using outdoor lighting to accentuate the planter and create an inviting ambiance in the evenings.

Experiment with different combinations of plants and decorations to create a unique and personalized look for your large outdoor planters.
