Common poppy: Diseases and Remedies (Explained for Beginners)

NOTE: The terms Common poppy and Papaver rhoeas are identical in this text; in reality, Papaver rhoeas is Common poppy’s biological word.

The Papaver rhoeas is an annual wildflower characterized by striking red blooms. The seeds of the common poppy can be germinating for up to 80 years after the soil is disturbed. After World War I, it was used as a symbol of remembrance because of the growth of poppies on the battlefields. The poem In Flanders Fields was written by a Canadian volunteer field medic.

Why does my Common poppy have gray mold spots?

Gray mold spots are a specific fungus that regularly harms flowers and spreads swiftly. If you notice any brown (or gray) spots, this fungus is probably to cause. You risk your plant dying if you ignore these warning indications.

Our Solution

The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Papaver rhoeas 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 Common poppy have leaf spots?

Leaf 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 Common poppy owners.

Why are my Common poppy 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.

When it’s overwatering, simply reduce your watering frequency, and if you think it’s a nutrient deficiency, here’s how to check it:

Each deficiency produces a different yellowing on the Papaver rhoeas in question, here’s how to spot them:

  • 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 deficiency starts with the newest leaves, turning them yellow throughout.
  • 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.
  • A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.

Our Solution

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 Common poppy sunburned?

You can easily tell if your Common poppy (your Papaver rhoeas) 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 Common poppy 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 Common poppy leaves turning brown?

A plant’s browning leaves are typically a symptom that it has been sunburned and has been exposed to excessive amounts of direct sunlight. Don’t worry; your plant probably won’t perish as a result, but its growth will be negatively impacted.

Should I leave my Papaver rhoeas in direct sunlight?

No! Don’t leave your Papaver rhoeas (or Common poppy) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.

Our Solution

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

Why are my Papaver rhoeas leaves drooping or wilting ?

This typically occurs when your Papaver rhoeas 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 Papaver rhoeas 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 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 Common poppy right away after a dry time because you think 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 Papaver rhoeas

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 Papaver rhoeas.

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 Papaver rhoeas 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 Papaver rhoeas near a source of hot (or cold) air such as A/C units, radiators or the like.

Keep your Common poppy 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.

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

To remove the dust from the leaves of your plant, take a microfiber cloth and gently rub the leaves. You can wet the cloth to make it easier to remove the dust, but never use corrosive products (such as 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.

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!)
