Common Problems Encountered By Aphelandra Plants
Yellowing Leaves
Overwatering
Overwatering is one of the most common reasons for yellowing leaves in Aphelandra plants. When the soil is constantly wet, it can lead to root rot, which in turn affects the plant’s ability to absorb nutrients, leading to yellowing leaves.
Overwatering can also cause the leaves to become soft and wilted.
Solution: Allow the soil to dry out between waterings, and make sure the plant is not sitting in standing water. Ensure that the soil has proper drainage to prevent water from accumulating at the bottom of the pot.
Underwatering
Underwatering is another reason for yellowing leaves in Aphelandra plants. When the plant is not watered enough, the leaves can become yellow and dry.
Solution: Water the plant thoroughly once a week and make sure the soil is evenly moist. Use your finger to check the moisture level in the soil before watering.
Nutrient Deficiencies
Yellowing leaves can also be caused by nutrient deficiencies, particularly nitrogen, and iron. Nitrogen deficiency can cause the older leaves to turn yellow, while iron deficiency can cause the younger leaves to turn yellow.
Solution: Fertilize the plant with a balanced fertilizer every two weeks during the growing season, following the manufacturer’s instructions. Use a fertilizer that contains nitrogen and iron to address any deficiencies.
Brown Or Crispy Leaves
Too Much Sunlight
Aphelandra plants prefer bright but indirect sunlight. When they are exposed to direct sunlight for an extended period, it can cause the leaves to become brown or crispy.
Solution: Move the plant to a location where it receives bright, indirect sunlight. Alternatively, you can filter the sunlight using a sheer curtain.
Too Little Humidity
Aphelandra plants thrive in high-humidity environments, and when they are grown in a low-humidity environment, it can cause the leaves to become brown and crispy.
Solution: Increase the humidity around the plant by misting it regularly, placing a humidifier near the plant, or grouping it with other plants to create a microclimate.
Pest Infestation
Pests such as spider mites, mealybugs, and scale insects can infest Aphelandra plants and cause the leaves to become brown and crispy.
Solution: Inspect the plant regularly for pests, and treat any infestations promptly with an appropriate insecticide.
Failure To Bloom
Improper Light Exposure
- Aphelandra plants require bright but indirect sunlight to bloom. When they are grown in a location with insufficient light, it can affect their ability to produce blooms.
Solution: Move the plant to a location with brighter but indirect sunlight. Alternatively, you can use grow lights to supplement the light.
Nutrient Deficiencies
Aphelandra plants require specific nutrients, particularly phosphorus, to bloom. When there is a deficiency in phosphorus or other essential nutrients, it can lead to a failure to bloom.
Solution: Fertilize the plant with a fertilizer that is high in phosphorus, following the manufacturer’s instructions. Use a fertilizer formulated specifically for flowering plants.
Incorrect Temperature Range
Aphelandra plants require warm temperatures between 65 and 75°F (18-24°C) to bloom. When they are grown in a location with temperatures outside of this range, it can affect their ability to produce blooms.
Solution: Move the plant to a location with temperatures within the ideal range. Avoid placing the plant near cold drafts or heating vents.
Root Rot
Overwatering
Overwatering can lead to root rot, which can be fatal to the plant. When the soil is constantly wet, it can cause the roots to rot and affect the plant’s ability to absorb nutrients.
Solution: Allow the soil to dry out between waterings and make sure the plant is not sitting in standing water. Ensure that the soil has proper drainage to prevent water from accumulating at the bottom of the pot.
Poor Drainage
Poor drainage is another reason for root rot in Aphelandra plants. When the soil does not drain properly, it can cause water to accumulate at the bottom of the pot, leading to root rot.
Solution: Ensure that the pot has adequate drainage holes to allow excess water to drain out of the soil. Use a well-draining soil mix that allows water to flow through freely.
Fungal Infections
Fungal infections such as Pythium and Phytophthora can also cause root rot in Aphelandra plants. These infections thrive in damp conditions and can be difficult to treat.
Solution: Apply a fungicide to the soil to treat any fungal infections. Ensure that the soil is not too wet, and the plant is not overwatered.
Solutions To Aphelandra Plant Problems
