The golden ball, also known as Echinocactus grusonii, is rare in its native habit, but it is often grown as a houseplant. It is rarely used in the outdoor garden in dry climates where temperatures never fall below 40 degrees. When it’s grown in a garden or yard, the cactus is more likely to flower indoors. The flowers will come in the spring if it does bloom.

Why are my Golden barrel cactus leaves turning yellow?

In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.

Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:

Here are some indicators of yellowing on the Echinocactus grusonii brought on by its numerous flaws:

  • Magnesium deficiency starts as yellow patches between leaf veins on older leaves. Veins stay green as yellow moves from the leaf center out. Leaf edges turn yellow last.
  • Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
  • The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
  • Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown.
  • Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.

Our Solution

According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.

Is my Golden barrel cactus sunburned?

It is quite easy to find out if your Golden barrel cactus (Echinocactus grusonii) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.

Sunburned

As we saw above, if your Golden barrel cactus receives too much water or not enough light, the leaves may also change color.

The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.

Why are my Golden barrel cactus leaves turning brown?

Most of the time, leaves of a Golden barrel cactus that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.

Should I leave my Echinocactus grusonii in direct sunlight?

No! If your Echinocactus grusonii (or Golden barrel cactus) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Golden barrel cactus is in such a state!

Our Solution

As explained in the paragraph above, the solution is simple, just place your Golden barrel cactus in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.

Why are my Echinocactus grusonii leaves drooping or wilting ?

When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.

Drooping

You may quickly determine if your Echinocactus grusonii plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.

Our Solution

If the soil in your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Golden barrel cactus right after a dry period thinking that it needs a lot of water.

This is the case, but giving too much water at once is the best way to finish it off, you should actually water the soil normally, resuming a quiet watering rhythm.

Caring Tips for Echinocactus grusonii

Water Occasionally

Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.

Touching the soil will let you know whether your plant needs water or not; if it still feels damp, it’s generally best to wait a few more days.

Always keep temperatures stable

It is also a good idea to keep your Echinocactus grusonii at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Echinocactus grusonii near a source of hot (or cold) air such as A/C units, radiators or the like.

Keep your Golden barrel cactus Dust-Free

This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.

This would be a true journey into hell for your Golden barrel cactus and would also satisfy the pests.

To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances like rubbing alcohol!

Keep drainage in mind

If you tend to overwater, you need to pay attention to your drainage, and we advise choosing a saucer and a pot with drainage holes if they are not already there.

You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
