Why did the thorns of the golden echinops turn black?

The hard thorns of golden echinops turn black - lack of water

The hard thorns of the golden barrel cactus will turn black. One of the reasons is that the plant lacks water.

The golden barrel cactus is a relatively drought-resistant plant. It does not need to be watered too frequently or too much. Generally, it does not need to be watered every day. However, this does not mean that you can go without watering the golden barrel cactus for a long time. At least you need to replenish water in time during the growth period of the golden barrel cactus. Otherwise, the golden barrel cactus will not have sufficient water support during its growth, and the hard thorns on the ball will easily turn black.

Generally, in spring and autumn, watering is done once every two weeks or so. In summer, the plants will be dormant, but they need to be sprayed with water frequently to ensure that the soil surface is moist. However, when watering, be sure not to water the hairs on the top of the golden barrel cactus, as this may cause the plant to rot.

The hard thorns of golden echinops turn black - too much fertilizer

The hard thorns of the golden barrel cactus may turn black, which may be due to too much fertilizer. When too much fertilizer is applied, the hard thorns will easily turn black.

When the golden barrel cactus is growing, it does not require high fertilizer requirements, so there is no need to fertilize too frequently during cultivation. Generally, fertilizing once a month is sufficient. In summer and winter, because the plants are dormant and grow slowly, there is generally no need to fertilize. If too much fertilizer is applied when growing golden barrel cactus, the golden barrel cactus will not grow well and its hard thorns will turn black. Therefore, do not apply too much fertilizer when applying fertilizer.
