NOTE: The terms Cordyline and Cordyline terminalis are identical in this text; in reality, Cordyline terminalis is Cordyline’s biological word.
An excellent houseplant with long, spikey leaves, cordyline is a common decorative plant that thrives outdoors in the USDA’s hardiness zones 9 through 12. The leaves of cordyline are usually green, red, yellow, white, purple, and purplish-red.
Why does my Cordyline terminalis roots have rot?
If left untreated, root rot on your Cordyline (Cordyline terminalis) 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 Cordyline 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 Cordyline terminalis 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 Cordyline 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 Cordyline owners.
Why are my Cordyline leaves turning yellow?
This is probably the most common problem in the gardening world, yellowing leaves. There are 2 main reasons for this phenomenon, overwatering, or a lack of nutrients.
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 Cordyline terminalis 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.
- Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
- 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.
- Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.
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 Cordyline sunburned?
It is simple to determine whether your Cordyline (your Cordyline terminalis) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.
The leaves of your Cordyline 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 Cordyline 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 Cordyline terminalis in direct sunlight?
No! If your Cordyline terminalis (or Cordyline) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Cordyline is in such a state!
The remedy, as said in the paragraph above, is simple: just move your plant’s Cordyline out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.
Why are my Cordyline terminalis leaves drooping or wilting ?
When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.
You may quickly determine if your Cordyline terminalis 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 your plant’s pot is completely dry, you will need to start by moistening it so that the roots will also benefit from the water. A common mistake is to drown the Cordyline right after a dry period thinking that 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 Cordyline terminalis
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.
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 Cordyline terminalis 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 Cordyline terminalis near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Cordyline 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 also make the pests happy, a real descent into hell for your Cordyline.
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 need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.
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.
