NOTE: The terms Melon cactus and Melocactus are identical in this text; in reality, Melocactus is Melon cactus’s biological word.
There are more than 30 species of cacti in the melon cactus. The cephalium, a bristly red or white structure that protrudes from the top of the plant from which pink to red flowers grow, is an attractive feature for growers. The common name for this plant is the Turk’s cap cactus, because it looks like a Fez hat. Fruits that are shaped like peppers attract birds and other wildlife.
The young melon cacti don’t have the cephalium, they develop in mature plants. The melon cacti look like a basic cactus with a green round or cylindrical shape, but it’s best to plant them in the spring. The plants have a moderate growth rate, with some species growing faster than others.
Why does my Melocactus roots have rot?
Root rot on your Melon cactus (Melocactus) can be dangerous if left untreated. In order to keep your plant alive, we strongly suggest that you follow our advice if the signs start to show: blackened and mushy roots.
Why does my Melon cactus have gray mold spots?
Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Melocactus. We advise you to remove the infected parts of the plant, cut off the infected roots and leaves, then repot your plant using sterile potting soil and a clean pot.
Why does my Melon cactus have leaf spots?
We provide you with all the information you need to identify and save your plants if they display signs like leaves that suddenly change color or wilt/droop. This sort of sickness is one of the most aggravating for Melon cactus owners.
Why are my Melon 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 signs of yellowing caused by the many deficiencies on the Melocactus in question:
- 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.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
- Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.
Is my Melon cactus sunburned?
It is simple to determine whether your Melon cactus (your Melocactus) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
As we saw above, if your Melon cactus receives too much water or not enough light, the leaves may also change color.
However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.
Why are my Melon cactus leaves turning brown?
Most of the time, leaves of a Melon 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 Melocactus in direct sunlight?
No! If your Melocactus (or Melon cactus) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Melon cactus is in such a state!
As explained in the paragraph above, the solution is simple, just place your Melon 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 Melocactus leaves drooping or wilting ?
In most cases, this happens when your Melocactus lacks water. This is especially the case for large plants, naturally they need more water than others.
You may quickly determine if your Melocactus plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the Melon cactus right away after a dry time because you think it needs a lot of water.
This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.
Caring Tips for Melocactus
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.
You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.
Always keep temperatures stable
Maintaining a consistent temperature for your Melocactus is also a good idea, especially if it is kept indoors. At GreenShack, we typically advise reserving a temperature between 65 and 85 degrees F. Of course, avoid positioning your Melocactus close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Melon cactus Dust-Free
This one is about houseplants. Your indoor plants’ leaves get dusty just like your furniture does. The problem is that this might prevent photosynthesis from beginning, which would result in the plants gradually losing their color.
This would be a true journey into hell for your Melon 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 have a tendency to overwater, you should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.
In the meantime, if you don’t have holes in your pots, you can add volcanic rocks (or any rocks with holes) at the bottom of your pot, this way it will create a channel so that the water doesn’t stay in your skin too much (to avoid that roots start to rot!)
