Why are my Mexican Cigar Plant 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.

Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:

Each deficiency produces a different yellowing on the Cuphea ignea in question, here’s how to spot them:

  • Yellow patches between leaf veins on elder leaves are the first sign of magnesium shortage. Veins continue to be green while the leaf’s core turns yellow. The leaf’s edges yellow last.
  • Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
  • Sulfur deficiency starts with the newest leaves, turning them yellow throughout.
  • Leaf edges turning bright yellow but inside leaf remaining green are signs of potassium insufficiency. The symptoms first appear on older leaves, and the leaf edges quickly become dark.
  • A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.

Is my Mexican Cigar Plant sunburned?

It is simple to determine whether your Mexican Cigar Plant (your Cuphea ignea) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.

Sunburned

The leaves of your Mexican Cigar Plant can also change color in case it gets too much water or not enough light, as we saw above.

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 Mexican Cigar Plant leaves turning brown?

A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.

Should I leave my Cuphea ignea in direct sunlight?

No! If your Cuphea ignea (or Mexican Cigar Plant) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Mexican Cigar Plant is in such a state!

Why are my Cuphea ignea leaves drooping or wilting ?

In most cases, this happens when your Cuphea ignea lacks water. This is especially the case for large plants, naturally they need more water than others.

Drooping

You may quickly determine if your Cuphea ignea 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 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 Mexican Cigar Plant right away after a dry time because you think 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 Cuphea ignea

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.

The best way to know if your plant needs water or not is to touch the soil, if you feel it is still wet, it is probably a good idea to wait a few more days.

Always keep temperatures stable

Maintaining a consistent temperature for your Cuphea ignea 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 Cuphea ignea close to air conditioners, radiators, or other sources of hot or cold air.

Keep your Mexican Cigar Plant Dust-Free

This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.

For your Mexican Cigar Plant, this would be a true descent into hell, and it would also appease 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!)
