Large planters offer a fantastic way to add a touch of nature to your home or garden. But filling them correctly is key to healthy plant growth. This comprehensive guide will walk you through each step, ensuring your plants thrive. Whether you’re a seasoned gardener or just starting out, these tips will help you succeed.

Choosing the Right Materials

Before you even think about plants, selecting the right materials for your planter is crucial. This impacts drainage and your plant's overall health.

1. Drainage is Key

Excellent drainage is paramount. Soggy roots lead to root rot, a common killer of potted plants. If your planter doesn't have drainage holes, you must add them. You can do this with a drill and a masonry bit (for ceramic or stone) or a sharp knife (for plastic).

2. The Base Layer: Drainage Material

A layer of drainage material at the bottom prevents waterlogging. Common choices include:

Broken Pottery: Affordable and readily available, broken pieces of old pots provide excellent drainage.
Gravel: Another inexpensive option, but ensure it's relatively small to avoid blocking drainage holes.
Potting Shard: Specifically designed for drainage, these provide an excellent base layer.

Add a 2-3 inch layer of your chosen material to the bottom of your planter.

3. The Next Layer: Landscape Fabric (Optional)

While optional, landscape fabric offers several benefits: it prevents drainage material from mixing with your potting soil, keeping your soil cleaner and preventing clogs.

Filling the Planter with Soil

Now for the soil! Using the right potting mix is as important as drainage. Don't use garden soil; it's too dense and retains too much water.

1. Choosing the Right Potting Mix

A well-draining potting mix is essential. Look for mixes labeled "potting soil" or "all-purpose potting mix". Avoid garden soil.

2. Adding the Potting Mix

Carefully add the potting mix, filling the planter about halfway. Avoid compacting the soil. Leave space for your plants and to top it off later.

Planting Your Chosen Plants

With the soil ready, it's time to plant! Remember to consider your plant's size and space requirements.

1. Preparing Your Plants

Carefully remove plants from their nursery pots. Gently loosen any circling roots to promote healthy growth.

2. Planting the Plants

Place your plants in the planter, ensuring there's enough space between them. Fill the spaces around the plants with more potting mix, gently firming it around the base of each plant. Don't compact it too much.

3. Watering Your Planter

After planting, water thoroughly to settle the soil and ensure your plants are well-hydrated.

Top Dressing and Finishing Touches

The final touches will make your planter look its best!

1. Top Dressing

A top dressing of mulch or decorative gravel protects the soil, suppresses weeds, and enhances the planter's appearance.

2. Mulch Options

Consider organic mulches like shredded bark or cocoa hulls, or inorganic options like gravel or pebbles.

Maintaining Your Large Planter

Keep your large planter thriving with these essential maintenance tips:

Watering: Water deeply and less frequently. Check moisture levels regularly.
Fertilizing: Feed your plants regularly during the growing season with a balanced fertilizer.
Pruning: Prune as needed to maintain shape and remove dead or diseased growth.
Pest and Disease Control: Monitor for pests and diseases, and take appropriate action if necessary.

By following these steps, you can confidently fill your large planter, creating a beautiful and thriving display of plants. Remember, proper drainage, the right potting mix, and thoughtful plant selection are the keys to success!
