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:

Here are some signs of yellowing caused by the many deficiencies on the Aerangis spp. in question:

  • The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf yellow last.
  • Another indicator of iron deficiency is yellowing between leaf veins, but young leaves on plant tops and branch tips are first affected.
  • Sulfur shortage first affects the youngest leaves, turning them entirely 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.
  • 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.

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 Aerangis orchids sunburned?

You can easily tell if your Aerangis orchids (your Aerangis spp.) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.

Sunburned

As we saw above, the leaves of your Aerangis orchids 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 Aerangis orchids 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 Aerangis spp. in direct sunlight?

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

Our Solution

The remedy, as said in the paragraph above, is simple: just move your plant’s Aerangis orchids out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.

Why are my Aerangis spp. leaves drooping or wilting ?

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

Drooping

An easy way to know if your Aerangis spp. 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!

Our Solution

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 Aerangis orchids right after a dry period thinking that it needs 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 Aerangis spp.

Water Occasionally

Water is essential to the survival of your plant, however, it is important to balance the rate of watering. As we explained above, overwatering could have fatal consequences for your Aerangis spp..

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 Aerangis spp. 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 Aerangis spp. close to air conditioners, radiators, or other sources of hot or cold air.

Keep your Aerangis orchids 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.

This would also make the pests happy, a real descent into hell for your Aerangis orchids.

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.

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!).
