Choosing the Right Soil for Your Calibrachoa Plant:
What You Need to Know

Calibrachoa, also known as Million Bells, is a popular annual plant that produces beautiful, trumpet-shaped flowers in a variety of colors. These plants are great for hanging baskets, window boxes, and containers. One of the most important factors in growing healthy and beautiful calibrachoa plants is choosing the right soil. In this article, we will discuss what you need to know about selecting the ideal soil for your calibrachoa.

Understanding Calibrachoa Soil Requirements

Before we dive into the specifics of choosing the right soil, it’s important to understand the soil requirements of calibrachoa plants. These plants thrive in well-draining soil that is rich in organic matter. They prefer a slightly acidic soil with a pH level between 5.5 and 6.2. The soil should also be able to retain moisture without becoming waterlogged.

Types of Soil for Calibrachoa

There are several types of soil that are suitable for growing calibrachoa plants. Here are some of the most common options:

Potting Mixes

Potting mixes are a popular choice for growing calibrachoa in containers. These mixes are designed to provide good drainage and aeration while retaining moisture. Look for potting mixes that contain peat moss, perlite, vermiculite, and/or coconut coir.

Garden Soil

If you are planting calibrachoa in a garden bed, you can use garden soil as long as it is well-draining and has been amended with organic matter such as compost or aged manure.

Sandy Soil

Sandy soil drains well and is ideal for calibrachoa plants. However, it does not retain moisture well, so you may need to water your plants more frequently if you choose this type of soil.

Loamy Soil

Loamy soil is a combination of sand, silt, and clay and is considered ideal for growing a wide variety of plants, including calibrachoa. It provides good drainage and retains moisture well.

How to Prepare Soil for Calibrachoa

No matter what type of soil you choose, it’s important to prepare it properly before planting your calibrachoa. Here are some tips:

• If using potting mix, moisten it before planting.
• Make sure the soil is loose and crumbly.
• Add organic matter such as compost or aged manure to improve nutrient content.
• Test the pH level and adjust if necessary using lime or sulfur.
• Mix in slow-release fertilizer or apply liquid fertilizer every two weeks during the growing season.
