Lychee: Diseases and Remedies (Litchi chinensis)

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

The tropical broadleaf evergreen tree is native to China where it thrives in a warm, wet climate. Although grown commercially for its fruit, it is often used as a shade tree or specimen fruit tree.

Why does my Lychee 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

When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Litchi chinensis being overwatered. We urge you to cut off the infected roots and leaves, remove the affected sections of the plant, and then repot your plant in a fresh container with sterile potting soil.

Why does my Lychee have leaf spots?

Leaf This type of disease is one of the most frustrating for Lychee owners, we give you all the leads to spot and save your plants that present symptoms such as leaves that suddenly change color, or wilt/droop.

Why are my Lychee leaves turning yellow?

In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.

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 Litchi chinensis in question, here’s how to spot them:

  • 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.
  • 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.
  • Nitrogen deficiency shows up as a general yellowing. Older, inner leaves turn yellow first. As it progresses, yellowing moves outward, eventually reaching young leaves, too.

Our Solution

You only need to act in accordance with the symptoms listed above. You can address a potassium or nitrogen deficiency by buying a particular soil, and a gardening store consultant will be able to advise you on how to do that. Furthermore, you can also limit how frequently you water your plants.

Is my Lychee sunburned?

It is simple to determine whether your Lychee (your Litchi chinensis) has sunburn. Your plant will change color in this instance, beginning to turn yellow or white, much like it does on us.

Sunburned

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

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 Lychee leaves turning brown?

Most of the time, leaves of a Lychee 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 Litchi chinensis in direct sunlight?

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

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s Lychee 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 Litchi chinensis 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

You may quickly determine if your Litchi chinensis 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 Lychee 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 Litchi chinensis

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 Litchi chinensis.

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 Litchi chinensis 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 Litchi chinensis close to air conditioners, radiators, or other sources of hot or cold air.

Keep your Lychee 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 Lychee and would also satisfy the pests.

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 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.

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!).
