To keep the plant in desired size.
1. Adequate Sunlight and Proper Location
Being a cactus, bunny ear loves full and bright sunlight. Therefore, it is best to keep it in the spot that receives full Sun throughout the day.
Generally, Bunny Ear Cactus requires 14 hours of full sunlight to thrive.
If you live in apartments in cities, it may not be possible to find a spot receiving Sun throughout the day in your home.
In such a case, try to provide your polka dot cactus with at least 6 hours of full sunlight and bright indirect light at other times of the day.
Problems Due to Lack of Sunlight
- Pale or unhealthy-looking appearance.
- Browning or rotting symptoms in stem and roots.
- Stunted growth or unusually long growth of pads toward the light source.
Tips to Provide Adequate Light and Location
- Place your cacti in a South or West-facing window to provide enough sunlight throughout the day.
- Avoid placing your cacti in high humid rooms like the kitchen or bathroom.
- Place your cactus 6 to 12 inches below cool white Fluorescent lights (grow lights) for 14 to 16 hours to compensate for the plant’s light requirements.
- In winter, the bunny ear doesn’t need full direct sunlight as in summer; hence can be placed in a spot receiving bright indirect light.
- If your plant shows problematic symptoms, place it in full direct sunlight for some days till it revives.
2. Watering Requirement
Being a cactus species and succulent body type, Bunny Ear cactus can survive in less water and store water on its stem.
Therefore, only some sprinkles of water can be enough for your plant to quench its thirst.
You can water your cacti once every two weeks during the summer, while ceasing watering during the winter is best for their health.
Besides, make sure to wait until the soil is completely dried before watering again.
Make sure not to overwater your cacti. Dry soil gives cacti the desert-like soil conditions that suit best for it.
Problems Due to Improper Watering
- Even though the bunny ear can survive without water for a long time, it becomes pale and brown when it cannot bear the neglect.
- Lack of growth and shriveling of pad tips are the common symptoms of low water conditions.
- The cactus may become dry or callused when the lack of water condition is prolonged.
- Root rot is the biggest suffering your cacti may go through in case of overwatering.
- When it gets overwatered, Bunny Ear starts to get shrivel, drop downwards, and start to fall over.
- Brown spots are commonly seen in an overwatered cactus.
Tips to Provide Adequate Watering
- Water your bunny ear once in two weeks, ideally. However, you can water it ahead if the soil is completely dry.
- Before watering them, wait until the top 1 inch (2.5 cm) feels dry.
- Use unglazed terracotta pots with drainage holes. These pots drain out the excess water and help evaporate water, keeping the soil dry.
- Always use a well-draining potting mix so that the soil doesn’t hold much water.
- Avoid placing your cacti in high humid rooms like the kitchen or bathroom, as it is easy to overwater your plant in higher humid conditions.
3. High Temperature
The Bunny ear cactus loves warm temperature, and the ideal temperature is 70-100°F (21-37°C) for the summer and 50-65°F (10-18°C) for the winter season.
Even though it tolerates a lesser temperature during winter, low temperature during the summer season can be a deal-breaker.
Moreover, the bunny ear is intolerant to frost. Hence, it is necessary to maintain the temperature range to keep the cacti happy.
Problems Due to Improper Temperature
- A combination of high temperature more than 38°C and full exposure to Sun can cause sunburn in cactus, damaging the spines, stem, and root system.
- Extreme cold or freezing temperatures may cause the cactus tissues to soften. The tissue initially turns white, which later will turn black and decay.
- Failure to maintain the temperature may ultimately cause the death of the plant.
Tips to Maintain Ideal Temperature
- Air conditioners and heaters can be used to provide the ideal temperature conditions.
- However, don’t place the pot near them to prevent damage from the constant hot breeze.
- Don’t forget to bring the outdoor placed Cacti indoors during the very cold seasons.
- Keep your cacti away from single pan windows during the winter season.
- You can use frost cloths and burlap material to cover your plant during the winter season.
4. Low Humidity
Cactus like dry air, just like in the desert. Therefore, very high humidity is not tolerated and may cause the rotting of stems and roots.
The adequate relative humidity for bunny ear cactus is 40- 50%.
Most easily seen signs of high humidity are green or black stem molds and stem rots.
Tips to Maintaining Ideal Humidity
- Don’t place your bunny ear cactus in the kitchen or bathroom, where the humidity is naturally high.
- You can use a dehumidifier to sustain the ideal condition.
- A hygrometer can check the humidity of different locations before deciding a place for your plant.
- Misting your cacti occasionally is advisable but don’t overdo it.
