What type of soil is best for growing calla lily?

When it comes to growing calla lilies, choosing the right type of soil is crucial for their health. For growing calla lilies, the best soil is loose, well-draining, and consistently moist.

Enrich the soil with compost or manure for added nutrients. Aim for a slightly acidic pH range of 5.6 to 6.5. This type of soil provides optimal conditions for healthy and vibrant calla lily growth.

How to Make Potting Soil Mix for Calla Lily at Home?

Start with a base of peat moss

Peat moss serves as the primary component in the potting soil mix. It provides excellent moisture retention, allowing the soil to stay consistently moist, which is beneficial for calla lilies. Peat moss also helps improve the soil’s structure and nutrient-holding capacity.

Add perlite for improved drainage

Perlite is a lightweight volcanic mineral that aids in enhancing the soil’s drainage properties. It prevents waterlogging and allows excess water to flow out of the soil, preventing root rot. Perlite also adds air pockets to the soil, promoting root respiration and preventing suffocation of the roots.

Compost for nutrient enrichment

Compost is an excellent addition to the potting soil mix as it provides a rich source of organic matter and nutrients. It improves the soil’s fertility, supports beneficial microbial activity, and releases nutrients slowly over time. This nutrient enrichment helps promote healthy growth and robust blooms in calla lilies.

Coarse sand

Coarse sand aids in maintaining a well-draining soil structure. It prevents the soil from becoming compacted, which can hinder water drainage and root growth. The sand also helps improve aeration and prevents the soil from retaining excessive moisture.

To make the potting soil mix, combine one part peat moss, one part perlite, one part compost, and a small amount of coarse sand. Mix these ingredients thoroughly until well combined. Adjust the proportions if needed, ensuring the final mix has a loose and crumbly texture.

Difference between garden soil and potting soil

Garden Soil

Garden soil refers to the soil found naturally in your garden or outdoor growing area. It is the soil that developed over time and holds a mix of organic matter, minerals, and microorganisms.

Garden soil is suitable for growing plants directly in the ground, and is cheap as it doesn’t have ingredients like perlite, vermiculite and peat moss.

However, garden soil may not always be ideal for potted plants or container gardening. It tends to be heavier and more compacted, which can hinder proper drainage in containers. 

Potting Soil

Potting soil is specially designed and formulated for the specific needs of plants grown in containers. It is a commercially prepared mixture that provides the ideal growing environment for potted plants. Potting soil is typically lighter in texture and more well-draining than garden soil.

Potting soil is carefully blended to ensure proper aeration, moisture retention, and nutrient availability for plants in containers. It is a mix of organic materials like peat moss, compost, or coconut coir, along with additives such as perlite or vermiculite for improved drainage. 

Potting soil also undergoes sterilization processes to eliminate weed seeds, pests, and diseases that could harm potted plants. This creates a clean and controlled environment for your container-grown plants.

Do Calla Lilies Do Better in Pots or in the Ground?

Growing calla lilies in pots

Growing calla lilies in pots offers several advantages and they actually grow better. Firstly, pots provide more control over the growing environment, allowing you to optimize conditions for the plants.

You can choose the ideal potting soil, ensure proper drainage, and easily move the pots to different locations, depending on sunlight requirements or your preferences.

Potted calla lilies also work well for those with limited space or no garden. They can be placed on balconies, patios, or windowsills, bringing the beauty of these elegant flowers closer to your living space.

Potted calla lilies can also be brought indoors during cold weather, extending their growing season and allowing you to enjoy their blooms for longer.

Growing calla lilies on the ground

Planting calla lilies directly in the ground can be a good option if you have a garden or a designated planting area.

In the ground, calla lilies have more room for root expansion and can access natural nutrients in the soil. They can spread and multiply more easily, resulting in larger clusters of beautiful flowers.

When planted in the ground, calla lilies also benefit from the stability of the soil, as it provides a firm foundation for their growth. They can establish deeper root systems and withstand external factors like wind or extreme weather conditions more effectively.

Although, whether calla lilies do better in pots or in the ground depends on your choice and specific circumstances, space availability, and personal preferences.

When to Repot Calla Lily?

Repotting is necessary every year when the plant outgrows its current container or when the soil becomes depleted and loses its fertility.

The ideal time to repot a calla lily is during its dormant period, which usually occurs in late fall or winter. During this time, the plant is not actively growing, and repotting will do less stress to the plant. It’s best to wait until the foliage dies back naturally before proceeding with repotting.

Signs that indicate it’s time to repot your calla lily include the roots becoming tightly packed or coming out from drainage holes. These signs suggest that the plant has used up the available space and nutrients in its current pot.

When it comes to repotting, opt for a container that is slightly larger than the current one in size. Ensure the new pot has drainage holes to allow excess water to escape. Prepare a fresh potting mix suitable for calla lilies, ensuring it is well-draining and nutrient-rich.

Gently remove the calla lily from its current pot, taking care not to damage the roots. If the roots are tightly bound, you can gently loosen them with your fingers. Place the calla lily in the new pot, ensuring the crown of the plant sits at the same level as before. Fill the remaining space with the fresh potting mix, pressing it lightly to secure the plant.

After repotting, water the calla lily to settle the soil around the roots. Place the plant in a location that receives bright, indirect light, and continue with your regular care.

Remember, repotting is not needed every year unless the plant shows clear signs of being root-bound.
