Lemon tree: Diseases and Remedies (Explained for Beginners)

NOTE: The terms Lemon tree and Citrus limon are identical in this text; in reality, Citrus limon is Lemon tree’s biological word.

Are you looking to grow your own fruit and don’t know where to start? Lemon trees can be grown in USDA Zones 8 through 11. The scent, color, and flavor of limon can be awakened. Young leaves are dark green on the surface and light green below. There are sharp thorns on the twigs of the tree.

The flowers are fragrant and come from buds. These blooms are either solitary or in small clusters of two or more. Four or five petals make up one flower, each of which is white on top and subtly purple beneath. Light-yellow to warm yellow fruit is dotted with oil glands.

Why does my Citrus limon roots have rot?

If left untreated, root rot on your Lemon tree (Citrus limon ) can be fatal. For this reason, if the symptoms appear, we highly advise that you adhere to our recommendations to keep your plant alive: Blackened and softened roots.

Why does my Lemon tree 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

When you understand the root of the issue, the solution makes perfect sense. The majority of the time, it is caused by the Citrus limon 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 Lemon tree have leaf spots?

Leaf We provide you with all the information you need to identify and save your plants if they display signs like leaves that suddenly change color or wilt/droop. This sort of sickness is one of the most aggravating for Lemon tree owners.

Why are my Lemon tree 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 Citrus limon 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 shortage first affects the youngest leaves, turning them entirely yellow.
  • Potassium deficiency shows itself when leaf edges turn bright yellow, but the inner leaf stays green. Older leaves show symptoms first, and leaf edges soon turn brown.
  • 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

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 Lemon tree sunburned?

You can easily tell if your Lemon tree (your Citrus limon ) 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 Lemon tree 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 Lemon tree leaves turning brown?

The classic sign that a plant has been overexposed to direct sunlight and sunburned is the development of browning leaves. Rest assured that while this may probably save your plant from dying, it will adversely affect its growth.

Should I leave my Citrus limon in direct sunlight?

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

Our Solution

As stated in the paragraph above, the cure is straightforward: simply position your plant’s Lemon tree 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 Citrus limon leaves drooping or wilting ?

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

Drooping

Whether your Citrus limon 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

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 Lemon tree 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 Citrus limon

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

It is also a good idea to keep your Citrus limon at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Citrus limon near a source of hot (or cold) air such as A/C units, radiators or the like.

Keep your Lemon tree 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 be a true journey into hell for your Lemon tree and would also satisfy the pests.

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 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!).
