Little Bluestem: Diseases and Remedies (2-minute Read)

NOTE: The terms Little Bluestem and Schizachyrium scoparium are identical in this text; in reality, Schizachyrium scoparium is Little Bluestem’s biological word.

The little bluestem is a warm-season prairie grass that is growing in popularity ornamentally. The silvery-blue color on the green stems and foliage makes this an attractive and adaptable choice as an accent in your borders. With a clumping habit, it works well in rockeries or meadow garden settings, and deep roots mean it can help prevent soil erosion.

The purple seed heads, stems, and foliage turn a copper-yellow shade in the fall, meaning that it’s a great winter-interest ornamental grass. The seeds can be planted in the spring or fall. When mass planting occurs in well-manicured landscapes, little bluestem self-seeds freely, so it can become a nuisance.

Why does my Little Bluestem 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 Schizachyrium scoparium 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 Little Bluestem have leaf spots?

Leaf If your plants exhibit symptoms like rapid color changes in the leaves or leaves that wilt or droop, we give you all the information you need to recognize them and rescue your plants. For owners of Little Bluestem, this kind of illness is among the most distressing.

Why are my Little Bluestem 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:

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

  • 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.
  • 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

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 Little Bluestem sunburned?

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

Sunburned

The leaves of your Little Bluestem can also change color in case it gets too much water or not enough light, as we saw above.

The bottom of the yellow leaves with a shaded area closer to the base can be examined to determine if they have been sunburned. If this part remains greener, the yellow leaf is most likely sunburned and not something else.

Why are my Little Bluestem 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 Schizachyrium scoparium in direct sunlight?

No! Don’t leave your Schizachyrium scoparium (or Little Bluestem) 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 Little Bluestem out of direct sunlight. Your plant should swiftly re-grow with this strategy and appropriate watering.

Why are my Schizachyrium scoparium 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.

Drooping

Whether your Schizachyrium scoparium 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

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 Little Bluestem after a dry period in the belief that it requires 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 Schizachyrium scoparium

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 Schizachyrium scoparium.

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 Schizachyrium scoparium 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 Schizachyrium scoparium close to air conditioners, radiators, or other sources of hot or cold air.

Keep your Little Bluestem 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 Little Bluestem.

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.

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.
