Scotch moss: Diseases and Remedies (Explained for Beginners)

NOTE: In this article, Scotch moss and Arenaria verna may be used interchangeably; in fact, Arenaria verna is the botanical name for Scotch moss.

Scotch moss is a herbaceous evergreen perennial that blankets the ground with dense mats of 1- to 2-inch tall plants that each spread 8 to 10 inches wide. There are clusters of tiny white flowers when Scotch moss blooms.

It will take several years to blanket an area if you plant Scotch moss too close to each other, as it has a slow growth rate. It lasts a short time and dies out after a few years. There’s generally no problem keeping an area carpeted with the signature yellow-green color because Scotch moss self-seeds.

Why are my Scotch moss 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 Arenaria verna 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.
  • Sulfur shortage first affects the youngest leaves, turning them entirely 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.
  • 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.

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 Scotch moss sunburned?

You can easily tell if your Scotch moss (your Arenaria verna) 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, if your Scotch moss 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 Scotch moss 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 Arenaria verna in direct sunlight?

No! If your Arenaria verna (or Scotch moss) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Scotch moss is in such a state!

Our Solution

As explained in the paragraph above, the solution is simple, just place your Scotch moss 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 Arenaria verna leaves drooping or wilting ?

In most cases, this happens when your Arenaria verna lacks water. This is especially the case for large plants, naturally they need more water than others.

Drooping

Whether your Arenaria verna 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 Scotch moss 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 Arenaria verna

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 Arenaria verna.

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’s also a good idea to keep your Arenaria verna at a constant temperature, especially if it’s kept indoors. In general, at GreenShack, we suggest booking a temperature between 65 and 85 degrees F. Of course, keep your Arenaria verna away from radiators, air conditioners, and other sources of hot or cold air.

Keep your Scotch moss 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 Scotch moss, 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.

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.
