Hosta: Diseases and Remedies (3-minute Read)

NOTE: In this article, Hosta and Hosta spp. may be used interchangeably; in fact, Hosta spp. is the botanical name for Hosta.

Hostas are shade tolerant plants with a wide variety of foliage colors. Perennials with rhizomatous roots reach maturity in about five years and are usually planted in the spring or fall. Hostas can make great houseplants if they are grown in containers. Hostas need an annual dormant period in cold conditions to thrive. Hosta can be grown indoors, where it is less susceptible to pests and diseases, if you can provide for its needs.

Here are some indicators of yellowing on the Hosta spp. brought on by its numerous flaws:

  • 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.
  • 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 lack of nitrogen is indicated by a widespread yellowing. Older, inner leaves are the first to yellow. As the yellowing progresses, it eventually touches young leaves as well.

Our Solution

Is my Hosta sunburned?

It is quite easy to find out if your Hosta (Hosta spp.) 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 Hosta 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 Hosta leaves turning brown?

Most of the time, leaves of a Hosta 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 Hosta spp. in direct sunlight?

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

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s Hosta 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 Hosta spp. leaves drooping or wilting ?

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

Drooping

You may quickly determine if your Hosta spp. 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

If the soil in the container is completely dry, you must first moisten it to guarantee that your plant’s roots absorb the benefits of the water. One common mistake is to drown the Hosta right away after a dry time because you think it needs 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 Hosta spp.

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.

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

It’s also a good idea to keep your Hosta spp. at a constant temperature, especially if it’s kept indoors. In general, at GreenShack, we suggest booking a temperature between 65 and 85 degrees F. Of course, keep your Hosta spp. away from radiators, air conditioners, and other sources of hot or cold air.

Keep your Hosta Dust-Free

This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.

This would be a true journey into hell for your Hosta and would also satisfy the pests.

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.

You can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the interim if your pots don’t already have holes in them. This will help to form a channel so that the water doesn’t pool there for too long (preventing the rot of the roots!).
