NOTE: In this article, Rainbow eucalyptus and Eucalyptus deglupta may be used interchangeably; in fact, Eucalyptus deglupta is the botanical name for Rainbow eucalyptus.
The rainbow eucalyptus tree is named because of the streaks of green, red, orange, gray, and purple that run along the trunk and branches. Outside of its native tropical setting, the rainbow colors are not as pronounced.
Even though it’s a striking gum tree, it can produce small clusters of white flowers in different seasons after the first year or two. In places like Hawaii, where the humid, warm weather suits this species, it’s often grown as a large focal landscape tree and can be seen providing shade along the edges of the streets.
Why does my Eucalyptus deglupta roots have rot?
Root rot on your Rainbow eucalyptus (Eucalyptus deglupta) 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 Rainbow eucalyptus have gray mold spots?
A particular fungus that frequently affects flowers and spreads quickly is known as gray mold spots. This fungus is most likely to blame if you see any brown (or gray) spots. Don’t ignore these signs because doing so could cause your plant to die.
When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Eucalyptus deglupta being overwatered. We urge you to cut off the infected roots and leaves, remove the affected sections of the plant, and then repot your plant in a fresh container with sterile potting soil.
Why does my Rainbow eucalyptus 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 Rainbow eucalyptus, this kind of illness is among the most distressing.
Why are my Rainbow eucalyptus 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:
Here are some indicators of yellowing on the Eucalyptus deglupta brought on by its numerous flaws:
- 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.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- The newest leaves are first affected by sulfur deficiency, rendering them completely yellow.
- Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown.
- 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.
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 Rainbow eucalyptus sunburned?
It is quite easy to find out if your Rainbow eucalyptus (Eucalyptus deglupta) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.
The leaves of your Rainbow eucalyptus 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 Rainbow eucalyptus 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 Eucalyptus deglupta in direct sunlight?
No! Don’t leave your Eucalyptus deglupta (or Rainbow eucalyptus) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
As explained in the paragraph above, the solution is simple, just place your Rainbow eucalyptus in a place where the light does not reach it directly, in this way and with a correct watering, your plant should resume its life rather quickly.
Why are my Eucalyptus deglupta leaves drooping or wilting ?
In most cases, this happens when your Eucalyptus deglupta lacks water. This is especially the case for large plants, naturally they need more water than others.
An easy way to know if your Eucalyptus deglupta 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!
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the Rainbow eucalyptus after a dry period in the belief that it requires 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 Eucalyptus deglupta
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 Eucalyptus deglupta.
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 Eucalyptus deglupta 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 Eucalyptus deglupta near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Rainbow eucalyptus 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.
For your Rainbow eucalyptus, this would be a true descent into hell, and it would also appease the pests.
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.
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!)
