NOTE: The terms Crossandra and Crossandra infundibuliformis are identical in this text; in reality, Crossandra infundibuliformis is Crossandra’s biological word.
Depending on where you live, Crossandra can be grown outdoors as an annual or a perennial. It provides a burst of indoor color with its brilliant blooms and green leaves. Crossandra can be mixed with other sun-loving plants in annual North American gardens, but it prefers tropical and humid conditions.
The plant has narrow, oblong leaves and peach or coral flowers. The best time to plant Crossandra is in the spring when the weather is dry and light. It should bloom all summer long in your pollinator garden, where it will attract butterflies and bees.
Why does my Crossandra infundibuliformis roots have rot?
Root rot on your Crossandra (Crossandra infundibuliformis) 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 Crossandra have gray mold spots?
A particular fungus known as gray mold spots spreads quickly and frequently damages flowers. This fungus is probably to blame if you see any brown (or gray) spots. If you disregard these warning signs, your plant could die.
The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Crossandra infundibuliformis 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 Crossandra 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 Crossandra, this kind of illness is among the most distressing.
Why are my Crossandra 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.
When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:
Each deficiency produces a different yellowing on the Crossandra infundibuliformis 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.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- 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.
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 Crossandra sunburned?
It is simple to determine whether your Crossandra (your Crossandra infundibuliformis) 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 Crossandra 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 Crossandra leaves turning brown?
Most of the time, leaves of a Crossandra 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 Crossandra infundibuliformis in direct sunlight?
No! If your Crossandra infundibuliformis (or Crossandra) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Crossandra is in such a state!
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Crossandra so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.
Why are my Crossandra infundibuliformis leaves drooping or wilting ?
This typically occurs when your Crossandra infundibuliformis gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
An easy way to know if your Crossandra infundibuliformis is lacking water is to under-weigh its pot, if it looks light, it means that the soil and the roots are probably quite dry, and therefore need 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 Crossandra 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 Crossandra infundibuliformis
Your plant needs water to survive, but it’s crucial to balance the amount and timing of watering. As we previously mentioned, overwatering could be catastrophic for your Crossandra infundibuliformis.
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 Crossandra infundibuliformis 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 Crossandra infundibuliformis near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Crossandra 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 Crossandra, 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.
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!).
