NOTE: Lisianthus may be referred to as Eustoma russellianum in this article, in fact, those are the same plants, Eustoma russellianum is the botanical name for Lisianthus.
A tender perennial flower, lisianthus is often grown as an annual. lisanthus has large purple and white bell-shaped flowers with flaring lobes that bloom on one or more upright stems, but the effort is clearly worthwhile for anyone interested in cut flower work.
It is often celebrated as a flower that looks like a rose but lasts longer in the vase and is in great demand for bridal bouquets and other special-occasion flower arrangements. You can usually find lisianthus plants in white, pink, purple, and cream, but you can occasionally find yellow or red flowering plants for sale.
The foliage of the flower is dark green and lance-shaped.
Why does my Eustoma russellianum roots have rot?
Root rot on your Lisianthus (Eustoma russellianum) can be fatal if not treated with care. For this reason, we strongly recommend that you follow our guide to keep your plant alive if the symptoms occur: Root soft and blackened.
Why does my Lisianthus 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 Eustoma russellianum 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 Lisianthus have leaf spots?
If your plants exhibit symptoms like rapid color changes in the leaves or leaves that wilt or droop, we give you all the information you need to recognize them and rescue your plants. For owners of Lisianthus, this kind of illness is among the most distressing.
Why are my Lisianthus leaves turning yellow?
Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.
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:
Each deficiency produces a different yellowing on the Eustoma russellianum in question, here’s how to spot them:
- 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 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 Lisianthus sunburned?
You can easily tell if your Lisianthus (your Eustoma russellianum) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
The leaves of your Lisianthus 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 Lisianthus leaves turning brown?
The classic sign that a plant has been overexposed to direct sunlight and sunburned is the development of browning leaves. Rest assured that while this may probably save your plant from dying, it will adversely affect its growth.
Should I leave my Eustoma russellianum in direct sunlight?
No! Don’t leave your Eustoma russellianum (or Lisianthus) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
The remedy, as said in the paragraph above, is simple: just move your plant’s Lisianthus out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Eustoma russellianum leaves drooping or wilting ?
In most cases, this happens when your Eustoma russellianum lacks water. This is especially the case for large plants, naturally they need more water than others.
Whether your Eustoma russellianum 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 Lisianthus 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 Eustoma russellianum
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
It is also a good idea to keep your Eustoma russellianum 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 Eustoma russellianum near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Lisianthus 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 Lisianthus 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.
If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
