Overwatering a golden barrel cactus can lead to a yellow coloration. Overwatering causes the cactus roots to sit in soggy soil which prevents them from effectively absorbing nutrients and oxygen. This overstressed condition can cause the cactus to change color to yellow, indicating potential root rot or fungal disease.
The solutions to this problem include first, stop watering the cactus immediately. Allow the soil to dry out completely between watering sessions. If the cactus is in a pot, ensure the pot has adequate drainage holes to release excess water. A well-drained soil mix designed specifically for cacti can also help prevent overwatering issues.
In severe cases where root rot has occurred, the affected roots should be removed and the cactus replanted in fresh, well-drained soil. It’s crucial to regulate water administration to prevent future overwatering, especially in colder months when the cactus is dormant and needs less water.
2. Underwatering

Impact of Underwatering on Golden Barrel Cactus:
Underwatering your golden barrel cactus could be the cause behind its yellow coloration. Cacti are adapted to endure harsh, dry conditions; they need less water than many other plants. However, insufficient watering can still cause harm. Underwatering can lead to water stress, causing your cactus to begin yellowing as a sign of deteriorating health.
Solutions for Underwatering:
Finding an optimal watering schedule is crucial. The key is not to water the cactus too often, but to water thoroughly when you do so. In cooler months when the cactus is dormant, water less frequently – perhaps once a month. During active growth in warmer months, watering every two weeks should suffice. Always ensure the soil is completely dry before re-watering to avoid root rot.
Further Caring Tips:
Position your cactus in a sunny, well-ventilated area to promote efficient water usage and healthy growth. Consider using a well-draining cactus mix to prevent water-logging. Regularly check your cactus for signs of distress and adjust your care accordingly. This will be beneficial for the overall health of your golden barrel cactus.
Assessing whether underwatering is indeed the issue can be done by checking the cactus’ firmness. If it feels soft or starts to shrivel, it might need more water. However, always verify that the yellowing isn’t due to a more serious issue, such as disease or pest infestation. Proper care and observation can keep your golden barrel cactus healthy and vibrant.
Remember, each plant is unique and may require personalized care. Therefore, always keep an eye on any changes to better meet its needs.
3. Lack of sunlight

|---|---|
| Solution | Increase exposure to sunlight. |
A golden barrel cactus turning yellow may be due to a lack of sufficient sunlight. Sunlight is crucial for the process of photosynthesis which in turn, is needed for the plant to grow well and maintain its vibrant green color.
When a plant is deprived of light, it can start to yellow – a process known as chlorosis. This is because the chlorophyll (the pigment that gives plants their green color and allows them to photosynthesize) starts to break down. Inadequate sunlight prevents the cactus from producing enough chlorophyll, leading to the yellow color.
As for the solution, you need to move your golden barrel cactus to a sunnier location. Consider a spot with at least 6 hours of direct sunlight each day. Also, maintain a consistent sunlight exposure as sudden variations can stress the plant. Remember, although these cacti are sun-loving plants, they also require some protection from the intense afternoon sun, especially in very hot climates. Hence, a location with early morning and late afternoon sun would be ideal. Monitor the cactus closely after making the shift to ensure it is adapting well to the new light conditions.
4. Nutrient deficiencies

| Solution | Increase exposure to sunlight. |
A nutrient deficiency can result in your Golden Barrel Cactus turning yellow. This is because these cacti, like all plants, require specific nutrients to maintain their normal physiological functions and overall health. When there’s a deficiency in these nutrients, the plant’s health starts to deteriorate, often exhibiting symptoms such as yellowing.
To resolve this issue, consider introducing a balanced cactus fertilizer into your plant care routine. A balanced cactus fertilizer typically contains equal amounts of nitrogen, phosphorus, and potassium (known as N-P-K), which are all essential nutrients for cacti. Administer the fertilizer according to the package instructions, typically during the plant’s active growing seasons (spring and summer) for best results.
Remember to also ensure your cactus is receiving the right amount of light, as insufficient light can exacerbate nutrient deficiency symptoms. Golden Barrel Cacti thrive in full sunlight, so depending on your region, indoor lighting conditions, and the time of year, you might need to supplement with a grow light.
Additionally, keeping an eye on watering frequency is important in preventing roots from rotting, which can also cause nutrient absorption issues. Golden Barrel Cacti like to dry out between waterings. This ensures that water doesn’t sit in the soil for extended periods, causing root rot and the subsequent nutrient absorption problems that lead to yellowing.
5. Pest infestation

|---|---|
| Solution | Apply organic insecticide and regularly inspect for pests to prevent further infestation and yellowing. |
Golden Barrel Cactus turning yellow can be due to a pest infestation. Pests such as mealybugs, scale and spider mites tend to hide in the cactus spines and crevices, feeding on the sap and causing the cactus to turn yellow. The plant’s health deteriorates as these pests deprive it of the nutrients it needs to survive and maintain its natural color.
To address this issue, you need to get rid of the pests invading your cactus. You can do this by using a soft brush or a cotton ball dipped in alcohol to carefully wipe off the pests. For severe infestations, you may need to use a proper insecticidal soap or spray that is safe for cacti. Apply according to the manufacturer’s instructions, ensuring to cover all parts of the plant, including the base and under the spines.
Once you have managed to control the pest problem, it is important to help your plant recover. Supplement its care with a balanced cactus fertilizer to replace lost nutrients and ensure it gets enough sunlight. Prevent future infestations by routinely checking your plant for pests and maintaining an appropriate watering schedule as overly wet conditions can attract pests.
6. Disease or fungal infection

The yellowing of Golden Barrel Cactus could be a sign of a disease or fungal infection. Infections usually occur due to overwatering, as damp conditions encourage bacteria and fungi to multiply. The excess moisture can also cause root rot which disrupts the plant’s ability to absorb nutrients, leading to discoloration and even death.
To address this problem, you need to first confirm if it’s truly an infection. This may require the help of a professional plant diagnostician. If an infection is confirmed, you could use fungicides or bactericides – but remember, these should be applicable to cacti.
Prevention is always better than cure. To prevent such problems, ensure good hygiene when repotting or cutting your cactus to minimize the transfer of harmful organisms. Also, consider maintaining a watering schedule that doesn’t make the soil soggy since cacti prefer dry conditions. Creating an environment that promotes good health will keep your Golden Barrel Cactus green and happy.
7. Aging or natural discoloration

The Golden Barrel Cactus can turn yellow due to overwatering which makes the roots waterlogged and leads to root rot. This issue hampers the nutrient and water transportation to the whole plant, causing it to turn yellow.
To rectify this problem, ensure proper watering methods. The right way to water a Golden Barrel Cactus is to soak the soil entirely and then let it dry completely before watering again. Overwatering leads to a lack of oxygen which in turn leads to the death of the roots and hence the yellowing of your cactus. It is preferable to underwater rather than overwater.
Furthermore, it is crucial to provide a proper drainage system while planting your cactus. Loose well-draining soil, such as a cactus mix, would work wonderfully. This helps to prevent excessive water retention. Also, if the plant has root rot already, it’s necessary to remove and replant the healthy parts in new soil after letting the cuts to heal for some days in open air.
