Do you know why cactus pads turn yellow and how to save them? Let’s tell you everything about the tricks with some secret tips!
Cacti are a popular choice as houseplants for both indoor and outdoor gardens among gardeners and plant enthusiasts. Although being one of the most resilient plants sometimes trouble surfaces them too. Here this guide will cover why cactus pads turn yellow and how to restore them. Read along!
Common Reasons for Yellowing Cactus Pads With Solutions
1. Improper Watering
Watering issues like overwatering and underwatering are the two main reasons for this nasty color change in cactus pads. Basically, cacti love to be on the drier side when it comes to watering because overly moist conditions do no good to their roots rather than rotting!
On the other hand, prolonged periods without any amount of water ultimately lead to dehydration, especially in dry regions with lots of sun exposure. This also causes the pads to shrivel and turn yellow.
Ensure the soil is completely dry before watering again. During the growing season, water your cactus thoroughly but infrequently, allowing excess water to drain away. In winter, reduce watering significantly.
2. Inadequate Lighting
It is obvious that these desert dwellers are sun lovers! So, you can guess that inadequate light can lead to various causes and one among them is etiolation, where the plant becomes pale and elongated and its pads may turn yellow.
The only solution to this issue is to place it in a sunny spot. Place your cactus in a location that receives bright, indirect sunlight. If moving a cactus outdoors, acclimate it gradually to prevent sunburn.
3. Poor Soil Drainage
The drainage hole and soil quality are the two things to consider while preparing the medium and container to grow a cactus. Because, a standard potting soil retains too much moisture, which isn’t an ideal growing medium for a cactus.
Additionally, the drainage hole matters, too as it helps drain out the excess water and maintain a healthy environment.
Use a well-draining cactus mix or create your own by combining potting soil with sand, perlite, or tiny pebbles. Along with this, ensure the pots have enough drainage holes to prevent water accumulation.
4. Nutrient Deficiencies
Honestly, cacti are not so dependent on nutrients in their native habitat but this thing doesn’t apply when you grow them as houseplants. In a container, nutrients are limited and need to be replenished from time to time to maintain balance.
Lack of nutrients particularly nitrogen, can cause yellowing of cactus pads. During the growing season, apply a balanced, water-soluble fertilizer formulated for cacti once a month.
5. Pest Infestations
Pests such as spider mites, mealybugs, and scale insects feed on cactus sap, leading to yellow spots and overall weakening of the plant. So keep a regular check on your cactus for any signs of pests or diseases. This helps prevention or early detection for taking measures accordingly.
If detected, remove them manually or use insecticidal soap or neem oil, ensuring thorough coverage of the affected areas.
6. Temperature Stress
Temperature stress, like consistent fluctuations and dry air pressure indoors, are the two main reasons to stress out a plant. Fluctuations mainly occur when you place them near a drafty window or a doorway. This is a big concern to be raised because many gardeners might not know it yet!
On the other hand, the placement of any plant near a heater, AC, or radiator can also cause multiple harms such as wrinkled pads, yellow or brown pads, and an overall weak plant.
Maintain a stable temperature environment for your cactus, avoiding sudden shifts. For this, choose a spot that is bright and stable. Additionally, protect cacti from frost by bringing them indoors during cold snaps.
7. Transplant Shock
Repotting or relocating a cactus can cause stress, resulting in yellowing pads. This is a natural defense mechanism that heals after some time with regular care and maintenance.
You can also minimize root disturbance during transplanting. After repotting, place the cactus in a shaded area and refrain from watering for about a week to allow it to acclimate. Simple!
By understanding and addressing these factors, you can effortlessly maintain the health of your cactus pads and ensure they retain their beautiful features. So, write to us if it works for you and for more additional information.
