Shasta daisy: Diseases and Remedies (Save your Plant Now!)

NOTE: The terms Shasta daisy and Leucanthemum superbum are identical in this text; in reality, Leucanthemum superbum is Shasta daisy’s biological word.

The Shasta daisy (Leucanthemum x superbum) is a hardy hybrid that was developed in the 1800s by crossing the oxeye daisy with several wild daisy varieties. There are 69 different types of the Shasta Daisy, according to the Royal Horticulture Society.

There are two types of flowers, single and double petals, and they all have bright white blooms with yellow centers. These plants have deep green foliage. In warm climates, the foliage is evergreen year-round.

Why does my Shasta daisy have gray mold spots?

Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.

Our Solution

The answer is obvious once you recognize the cause of the problem. Most frequently, it results from the Leucanthemum superbum 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 are my Shasta daisy leaves turning yellow?

Yellowing leaves are arguably the most prevalent issue in the gardening world. Overwatering or a lack of nutrients are the 2 main causes of this issue.

Whether you think your plants are getting too much water, cut back on how often you water them, and take the following measures to see if they might be nutritionally deficient:

Here are some signs of yellowing caused by the many deficiencies on the Leucanthemum superbum in question:

  • 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.
  • Yellowing between leaf veins is another sign of iron shortage, but young leaves on plant tops and branch tips are initially affected.
  • Sulfur shortage first affects the youngest leaves, turning them entirely yellow.
  • Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
  • 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 Shasta daisy sunburned?

It is quite easy to find out if your Shasta daisy (Leucanthemum superbum) 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

As we saw above, the leaves of your Shasta daisy 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 Shasta daisy 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 Leucanthemum superbum in direct sunlight?

No! If your Leucanthemum superbum (or Shasta daisy) has the symptoms described above, don’t leave it in direct sunlight, that’s the reason why your Shasta daisy is in such a state!

Our Solution

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

Why are my Leucanthemum superbum leaves drooping or wilting ?

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

Drooping

An easy way to know if your Leucanthemum superbum 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

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 Shasta daisy 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 Leucanthemum superbum

Water Occasionally

Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.

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 Leucanthemum superbum 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 Leucanthemum superbum close to air conditioners, radiators, or other sources of hot or cold air.

Keep your Shasta daisy Dust-Free

This one relates to indoor plants. Just like your furniture, dust collects on the leaves of your indoor plants. The issue is that this can block the photosynthesis process from starting, which would cause the plants to gradually lose their color.

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

To remove the dust, gently rub the plant’s leaves with a microfiber cloth. Dust can be removed more easily with a damp cloth, but stay away from corrosive substances 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.

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.
