Strawflower: Diseases and Remedies (Xerochrysum bracteatum)

NOTE: The terms Strawflower and Xerochrysum bracteatum are identical in this text; in reality, Xerochrysum bracteatum is Strawflower’s biological word.

The name straw flower doesn’t do much to impress the flower gardener, but the real straw flower blossom will bring vivid colors to your landscape and craft projects alike. The petals of strawberries are stiff and papery like daisies, but in form with a ray of petals around a central disk. They are not true petals at all, but modified leaves called bracts. Fine hairs cover the narrow green leaves and sturdy stems.

Why does my Strawflower 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

The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Xerochrysum bracteatum being overwatered.

Why are my Strawflower 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:

Here are some indicators of yellowing on the Xerochrysum bracteatum brought on by its numerous flaws:

  • 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.
  • 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.
  • 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 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 Strawflower sunburned?

It is quite easy to find out if your Strawflower (Xerochrysum bracteatum) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.

Sunburned

The leaves of your Strawflower 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 Strawflower leaves turning brown?

Most of the time, leaves of a Strawflower that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.

Should I leave my Xerochrysum bracteatum in direct sunlight?

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

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s Strawflower 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 Xerochrysum bracteatum leaves drooping or wilting ?

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

Drooping

You may quickly determine if your Xerochrysum bracteatum plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.

Our Solution

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 Strawflower 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 Xerochrysum bracteatum

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 Xerochrysum bracteatum.

You can tell if your plant needs water by touching the soil; if it still feels damp, it’s usually preferable to wait a few more days.

Always keep temperatures stable

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

Keep your Strawflower 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 Strawflower.

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.

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!)
