NOTE: The terms Dutch iris and Iris hollandica are identical in this text; in reality, Iris hollandica is Dutch iris’s biological word.
Dutch iris (Iris hollandica) is a hybrid iris. The Dutch people hybridized it, so its name doesn’t reflect its place of origin. The parent species of the Dutch iris is found in Spain and Portugal. Multi-colored flowers are the 3- to 4-inch flowers. Blue, bluish-purple, white, bronze, rose, gold, and yellow are some of the most popular colors.

Each deficiency produces a different yellowing on the Iris hollandica 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.
- 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.
- 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.
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 Dutch iris sunburned?
You can easily tell if your Dutch iris (your Iris hollandica) has a sunburn. In this case, your plant will change color, starting to turn yellow or white, much like it does on us.
The leaves of your Dutch iris can also change color in case it gets too much water or not enough light, as we saw above.
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 Dutch iris leaves turning brown?

No! Don’t leave your Iris hollandica (or Dutch iris) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Dutch iris so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.
Why are my Iris hollandica leaves drooping or wilting ?
When you become dehydrated, this usually happens. Large plants are more vulnerable since they need more water on a regular basis than smaller plants.
You may quickly determine if your Iris hollandica plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require 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 Dutch iris after a dry period in the belief that it requires 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 Iris hollandica
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 Iris hollandica.
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 Iris hollandica 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 Iris hollandica close to air conditioners, radiators, or other sources of hot or cold air.
Keep your Dutch iris 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.
This would also make the pests happy, a real descent into hell for your Dutch iris.
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 should be mindful of your drainage, and if they don’t already have them, we suggest selecting a saucer and a pot with drainage holes.
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!)
