However, this is not a reason for Harge the water floorBecause citrus fruits cannot endure to have the foot soaked. This prevents the air from circulating through the substrate, causing the asphyxiation of the roots.

The same problem occurs on lemon trees if planted in a heavy or clayey soil. The leaves that are the first to suffer from this phenomenon accumulate.

To make the lemon tree drink enough, without risking drowned, plant it in a pierced container. Therefore, the drainage holes will allow the Too full of water Exit the bottom in case of excessive watering. To avoid this type of problem, it is important to plant the lemon tree well and keep it well.

• iron.
• Magnesium.
• Potassium.

In the absence of these elements, the fruits of citrus fruits cannot produce chlorophyll, the substance that allows the leaves to have the green color. This leads to a disease called chlorosis.

In affected citrus fruits, the leaves change color. At the beginning, they saw light green, then they became yellow before dying. However, the ribs are spared from Yellowed leaves due to chlorosis.

Lemona with brown spots

THE Brown or brown tasks they are a phenomenon noticed in lemon trees with the Corynespoose. It is a disease caused by a mushroom known as Corynespora Cassicola.

At the beginning, it is in the form of light brown spots that both affect leaves, stems and fruits. Over the days, these spread becoming increasingly dark.

Plants with Corynespoose Capture the light with difficulty. Their rendering in terms of fruit decreases significantly. Furthermore, leaves and fruits begin to fall soon and very frequently.

However, it should be noted that when lemon leaves fall, this can also translate other health problems. To do this, be careful to diagnose the problem well to start the appropriate care.

The mushroom responsible for the disease of brown tasks is attracted to humidity and warmth. To stop its diffusion, the first thing is to eliminate all interested parties, including fruit.
