Ideal Growing Conditions for Bunny Ear Cactus

To keep your Bunny Ear Cactus healthy, it’s important to replicate its natural desert habitat as much as possible.

1. Light Requirements

• Indoors: Needs at least 6-8 hours of direct sunlight. A south-facing window is ideal.
• Outdoors: Thrives in full sun but should be protected from extreme heat in summer.

Tip: If your home doesn’t get enough sunlight, use a grow light to supplement.

2. Best Soil for Bunny Ear Cactus

• Prefers sandy, well-draining soil to prevent root rot.
• Use a cactus/succulent mix, or create your own:
  • 1 part potting soil
  • 1 part coarse sand
  • 1 part perlite or pumice

3. Watering Schedule

• Water sparingly—only when the soil is completely dry.
• In summer, water once every 2-3 weeks.
• In winter, reduce watering to once a month or less.

Avoid Overwatering: The biggest killer of Bunny Ear Cacti is root rot, caused by excessive moisture.

4. Temperature & Humidity

• Thrives in warm, dry conditions (70°F – 100°F or 21°C – 37°C).
• Not frost-tolerant—keep indoors if temperatures drop below 50°F (10°C).
• Avoid high humidity, as it increases the risk of fungal diseases.

5. Fertilizing

• Minimal fertilization required—once a year in spring using a cactus fertilizer.
• Over-fertilizing can lead to weak, leggy growth.

Pruning & Repotting Bunny Ear Cactus

Pruning Tips

• Trim off damaged or thin pads to encourage bushier growth.
• Always use thick gloves or tongs to handle the plant and avoid painful glochids.

When & How to Repot

• Repot every 2-3 years when the cactus outgrows its container.
• Steps for repotting:
  1. Wear gloves or use tongs to remove the plant.
  2. Gently shake off old soil from the roots.
  3. Transfer into a larger pot with fresh cactus soil.
  4. Wait a week before watering to allow roots to settle.

Propagating Bunny Ear Cactus

One of the best ways to expand your cactus collection is by propagation.

Steps to Propagate Bunny Ear Cactus from Cuttings:

Use a sharp, sterile knife to remove a healthy pad from the main plant.
Let it dry for 24-48 hours to form a callous (this prevents rotting).
Plant the pad cut side down in a well-draining soil mix.
Place it in bright, indirect sunlight.
Do not water until roots develop (around 2-3 weeks).

Common Problems & How to Fix Them

1. Root Rot (Caused by Overwatering)

Signs: Soft, brown, mushy base.
Solution: Cut off damaged areas and let the plant dry before repotting.

2. Drooping or Shrinking Pads

Signs: Pads looking thin or floppy.
Solution: Check watering routine—too much or too little water can cause drooping.

3. Pests: Mealybugs & Scale

Signs: White, cotton-like pests or small brown bumps on pads.
Solution: Use rubbing alcohol on a cotton swab to remove pests.
