Here are some signs of yellowing caused by the many deficiencies on the Stenotaphrum secundatum 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.
  • 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.

It is quite easy to find out if your St. Augustine grass (Stenotaphrum secundatum) 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, if your St. Augustine grass receives too much water or not enough light, the leaves may also change color.

However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.

Why are my Stenotaphrum secundatum 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

An easy way to know if your Stenotaphrum secundatum 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 St. Augustine grass 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 Stenotaphrum secundatum

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 Stenotaphrum secundatum.

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 Stenotaphrum secundatum 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 Stenotaphrum secundatum close to air conditioners, radiators, or other sources of hot or cold air.

Keep your St. Augustine grass 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 St. Augustine grass.

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.

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.
