Dendrobium orchid: Diseases and Remedies (Explained for Beginners)

NOTE: The terms Dendrobium orchid and Dendrobiumspp. are identical in this text; in reality, Dendrobiumspp. is Dendrobium orchid’s biological word.

One of the largest orchid groups has nearly 2,000 species. These plants grow in a wide range of climates, from hot, wet lowlands to high- altitude, cool mountains. Epiphytes are those plants that grow on other plants. They’re found on tree branches in nature.

All of the species come in a variety of pastels and are known for their profuse blooms. Some species bloom all along the stems while others bloom just from the tops of the stems. Some people drop their leaves in the fall, while others keep their leaves year-round.

Why does my Dendrobium orchid 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.

Our Solution

When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Dendrobiumspp. 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 Dendrobium orchid have leaf spots?

Leaf This type of disease is one of the most frustrating for Dendrobium orchid owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.

Why are my Dendrobium orchid 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:

Each deficiency produces a different yellowing on the Dendrobiumspp. 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.
  • 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.

Our Solution

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 Dendrobium orchid sunburned?

It is simple to determine whether your Dendrobium orchid (your Dendrobiumspp.) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.

Sunburned

As we saw above, the leaves of your Dendrobium orchid can also change color if it receives too much water or insufficient light.

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 Dendrobium orchid 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 Dendrobiumspp. in direct sunlight?

No! If your Dendrobiumspp. (or Dendrobium orchid) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Dendrobium orchid is in such a state!

Our Solution

As explained in the paragraph above, the solution is simple, just place your Dendrobium orchid 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 Dendrobiumspp. leaves drooping or wilting ?

This typically occurs when your Dendrobiumspp. gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.

Drooping

Whether your Dendrobiumspp. 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.

Our Solution

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 Dendrobium orchid 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 Dendrobiumspp.

Water Occasionally

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 Dendrobiumspp..

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

Maintaining a consistent temperature for your Dendrobiumspp. 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 Dendrobiumspp. close to air conditioners, radiators, or other sources of hot or cold air.

Keep your Dendrobium orchid 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.

For your Dendrobium orchid, 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 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.

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!).
