NOTE: Lemongrass may be referred to as Cymbopogon citratus in this article, in fact, those are the same plants, Cymbopogon citratus is the botanical name for Lemongrass.
For gardeners looking to get the most bang for their buck, certain edible landscaping plants, such as lemongrass, can fulfill two desires. The ornamental grass offers fresh herbs for the kitchen and increases curb appeal. It is appetizing in soups, stir-fries, and teas, and it is handsome in the summer breeze.
The crossandra is a perennial in zones 10 and 11 but is often grown as an annual in other regions. When it turns burgundy and red, the long, slender gray-green foliage adds gorgeous color to autumn gardens.
Why does my Cymbopogon citratus roots have rot?
If left untreated, root rot on your Lemongrass (Cymbopogon citratus) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.
Why does my Lemongrass have gray mold spots?
Gray mold spots are a specific fungus that regularly harms flowers and spreads swiftly. If you notice any brown (or gray) spots, this fungus is probably to cause. You risk your plant dying if you ignore these warning indications.
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Cymbopogon citratus being overwatered. We strongly advise you to remove the damaged plant parts, cut off the diseased roots and leaves, and then repot your plant in a new container with sterile potting soil.
Why does my Lemongrass 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 Lemongrass owners.
Why are my Lemongrass 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 Cymbopogon citratus 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.
- 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 lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.
You only need to respond to the signs mentioned above. A gardening store expert will be able to provide you advice on how to purchase a specific soil to treat a potassium or nitrogen deficiency. Additionally, you can reduce how often you water your plants.
Is my Lemongrass sunburned?
You can easily tell if your Lemongrass (your Cymbopogon citratus) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
As we saw above, if your Lemongrass receives too much water or not enough light, the leaves may also change color.
To find out if the yellow leaves have been sunburned, look at the part of the bottom that is tinted closer to the base. The yellow leaf is probably burnt and not something else if this portion stays greener.
Why are my Lemongrass 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 Cymbopogon citratus in direct sunlight?
No! If your Cymbopogon citratus (or Lemongrass) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Lemongrass is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Lemongrass out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Cymbopogon citratus leaves drooping or wilting ?
This typically occurs when your Cymbopogon citratus gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
Whether your Cymbopogon citratus plant’s pot appears light, the soil and roots are likely fairly dry and need water, so you can readily tell if it needs to be hydrated.
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 Lemongrass 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 Cymbopogon citratus
Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Cymbopogon citratus.
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 Cymbopogon citratus 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 Cymbopogon citratus close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Lemongrass 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 also make the pests happy, a real descent into hell for your Lemongrass.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials 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!)
