Amaryllis prefers soil that drains well which means it doesn’t hold onto excess water. So, it’s important to avoid heavy or compacted soil that can make the roots too wet and lead to problems like root rot. 

Instead, go for a soil mix that is loose and well-draining. An ideal mix consists of two parts loam, one part perlite and one part rotted manure.

In detail, loam gives essential nutrients, perlite helps with drainage and rotted manure adds fertility to the soil. This combination ensures that the soil retains enough moisture for the amaryllis to thrive while preventing excess water from causing problems like root rot.

Know Your Plant – Amaryllis

Amaryllis bulbs are well-known for their ability to bloom with ease which makes them a popular choice among flowering bulbs. They can be grown indoors or outdoors and can be enjoyed throughout an extended period.

Amaryllis originated from the tropical regions of South America and has large, captivating flowers. With a wide array of stunning varieties available, amaryllis blooms showcase an array of colours of red, white, pink and orange. 

As for their requirement, amaryllis thrives in bright locations with at least 6-8 hours of direct sunlight. Ensure the soil is well-draining to prevent overwatering and root rot. Water amaryllis regularly while allowing the top 2 inches of the soil to slightly dry out.

Use a balanced fertilizer during the active growing season to support healthy growth and vibrant blooms. Take the time to understand and meet the specific requirements of the amaryllis plant.

Best Soil for Amaryllis Bulbs

Choosing the right soil is important for the successful growth and blooming of amaryllis bulbs. The soil you use should include specific characteristics that promote healthy root development and provide adequate drainage. 

Well-Draining – Amaryllis prefer well-draining soil that allows excess water to flow through easily and also avoids heavy or compacted soil too.

Organic Matter – Amaryllis benefits from soil that is rich in organic matter. Organic materials, such as compost or rotted manure, improve soil fertility and provide essential nutrients for the bulbs. 

Balanced pH – Amaryllis bulbs thrive in soil with a slightly acidic to neutral pH range of around 6.0 to 6.8. 

Sterile and Disease-Free – It is beneficial to use sterile soil to minimize the risk of pests, diseases, and weed growth. This helps maintain the health of the amaryllis plant.

Let’s see now the best potting mixes for Amaryllis Bulbs –

1. This mix offers a good balance of organic matter and drainage.

  • Two parts loam (or garden soil) – Loam provides structure to the soil and helps retain moisture.
  • One part perlite – Perlite or sand improves drainage and prevents waterlogging.
  • One part rotted manure (or compost) – Rotted manure or compost enriches the soil with organic matter and nutrients.

2. This mix provides good drainage while offering necessary organic matter.

  • One part loam
  • One part coarse sand
  • One part compost

3. This mix is suitable when using commercial potting soil.

  • One-part potting soil (commercial mix) – Commercial potting soil provides a well-balanced base.
  • One part perlite
  • One part vermiculite – Vermiculite helps retain moisture while promoting root growth.

Remember, the key is to choose a soil mix that ensures good drainage, organic matter content, and a balanced pH. 

Homemade Potting Soil Mix for Amaryllis Bulbs

Creating your own potting soil for Amaryllis bulbs is easy. It’s a simple and rewarding process that ensures your plants receive the best-growing medium. Here’s a homemade potting soil mix recipe –

Combine Rich Organic Material with Inorganic Components

Mix one-third clean builder’s sand, one-third garden soil, and one-third well-rotted compost. This combination provides a balance of organic matter and inorganic components that promote good drainage.

Sterile Potting Soil with High Organic Matter

The University of Minnesota suggested to fill a pot halfway with a sterile potting soil mix that is rich in organic matter, such as peat moss. This helps retain moisture and provides essential nutrients for the amaryllis bulbs.

Ideal Potting Mix Recipe

For an ideal potting mix, combine two parts of loam soil, one part perlite, and one part of well-rotted manure. This mixture ensures good drainage, aeration, and nutrient availability for the bulbs.

By following this homemade potting soil mix recipe, you can give a nurturing environment for your amaryllis bulbs. The blend of organic and inorganic components ensures proper drainage, nutrient supply, and moisture retention.

Can I Use Cactus Soil for Amaryllis?

Yes, you can use cactus soil for growing amaryllis. Cactus soil can be used as it has excellent drainage properties, which can help prevent overwatering.

The main advantage of using cactus potting mix is its ability to minimize moisture retention. Amaryllis bulbs don’t like to sit in overly wet soil, so a soil mix that allows water to flow through easily is beneficial.

Furthermore, you can use a sterilized potting mix or regular garden soil for your amaryllis. To enhance drainage, you can add coarse perlite, which helps create air pockets in the soil and prevents water from accumulating around the bulbs.

To enrich the soil with organic matter and nutrients, consider incorporating worm castings. Worm castings are a natural byproduct of vermicomposting and provide both organic matter and beneficial nutrients for plants.

Repotting Amaryllis Plants

Repotting is normally done when the bulbs outgrow their current container or when the soil becomes depleted of nutrients. The ideal time for repotting amaryllis is once they have completed their dormant period.

Choosing the Right Pot

Select a pot that is slightly larger than the current one, allowing enough room for the roots to spread. Make sure the pot has the right and proper drainage holes to prevent waterlogging.

Soil Mix

Prepare a well-draining soil mix suitable for bulbs. You can also create a homemade mix by combining loam soil, perlite, and well-rotted compost for optimal drainage and nutrient availability.

Repotting Process

Gently remove the amaryllis plant from its current pot, being careful not to damage the roots. Remove any dead or decaying roots. Place the bulb in the new pot, ensuring it is centred and positioned at a proper depth. Fill the pot with the soil mix, gently firming it around the bulb.


After repotting, water the amaryllis thoroughly but avoid overwatering. Place the plant in a bright location with sunlight. Resume regular watering and fertilizing routines once new growth appears.

Amaryllis bulbs generally require repotting every two to three years, depending on their growth. Watch the plant’s growth and health to determine if repotting is necessary or not.

How to Plant & Grow Amaryllis?

Planting and growing amaryllis is an exciting experience. Follow these steps to ensure successful growth and beautiful blooms –


Select a healthy, firm Amaryllis bulb. Look for a bulb with no signs of damage or rot. Select a pot that features drainage holes at the bottom. Ensure the pot is large enough to adjust the bulb and leave some space for root growth.

Planting depth

Fill the pot with well-draining soil, leaving about one-third of the bulb exposed above the soil surface. Gently press the soil around the bulb, providing stability without compacting it too tightly.


After planting, give the amaryllis bulb a good watering. Keep the soil slightly moist but don’t overdo it. Water the plant thoroughly whenever the top 2 inches of soil feels like slightly dry.

Light and Temperature

Place the potted amaryllis in a bright location that receives direct sunlight. Amaryllis thrives in temperatures between 65-75°F.

Support and Growth

As the amaryllis grows, it may require support to keep the stem upright. Insert a stake or use plant support near the bulb, gently securing the stem without causing damage.


Feed the amaryllis with a balanced fertilizer specifically prepared for flowering plants. Follow the instructions on the fertilizer packaging for proper dilution and frequency. Fertilize the plant during the active growth phase.
