Why are the Leaves of my Lemon Sprout Turning Yellow?

Lemons are popular around the world. The citrus fruit first found its way to the Americas in 1493 with Christopher Columbus.

It’s a decorative plant, a citrus fruit, and a medication.

Growing your lemon trees is a rewarding endeavor, but it’s concerning when your lemon sprout leaves turn yellow.

 

Why Are the Leaves of My Lemon Sprout Turning Yellow?

Lemon leaves can turn yellow for several reasons. Generally, yellow leaves are a sign something isn’t right with the plant. Potential causes of yellow leaves include over or under watering, lack of sunlight, nutritional deficiencies, parasites, and seasonal changes.

Watering Issues

Lemon leaves becoming yellow is caused by a variety of factors, including Watering issues.

 

Overwatering

Overwatering is a common cause of yellow leaves on a lemon sprout. If not corrected, overwatering can even kill your lemon tree.

Sprouts require quite a bit of moisture, but too much can be problematic.

Overwatering can lead to root rot. Root rot is a fungal disease that is caused by excess moisture.

The disease causes the roots to become brown and mushy.

These damaged roots can’t bring in nutrients and water from the soil. Without adequate care, this will result in the plant dying.

In addition to yellowing leaves, the leaves may wilt or droop. Growth will slow or stop.

 

Underwatering

Underwatering is more common with lemon sprouts than overwatering. This is because lemon sprouts require more water than mature lemon trees.

The leaves will turn yellow if they are overwatered. The leaves will wilt, becoming dry or papery.

Growth will slow or stop if the plant is underwatered. If not corrected, the sprout will die.

 

How to Water a Lemon Sprout

When planting lemon seeds, cover the pot with plastic wrap. Make a few ventilation holes in it. This helps trap moisture and heat in the pot.

It’s essentially a miniature greenhouse. Keep it consistently moist until the sprout develops four or five leaves.

Then, switch to watering approximately once a week. Allow only the first inch of soil to completely dry out.

Simply insert your finger into the soil to check the moisture content.

Allow the first two inches of soil to dry before watering the sprout after it has reached maturity.

Depending on the conditions, this may also be about once a week.

Lack of Sunlight

Lemons are native to tropical locations. Today, they are still grown in tropical or warm areas, including Florida and Spain.

When growing lemon trees, they need full sunlight. Lots of strong direct sun will produce a healthy lemon tree.

Without enough sun, the leaves will turn yellow. Eventually, the leaves will turn pale and drop.

However, lemon sprouts require a gentler hand than mature lemon trees. Keep them in a bright, indirect light environment until they start to sprout.

They require at least 4 hours of sunshine every day once they have blossomed. However, the temperature should be between 60 and 70 degrees.

If the outside weather isn’t ideal, keep the lemon sprouts indoors near a window.

Nutritional Deficiency

Lemons require a lot of fertilizer to thrive. Nutritional deficiency is more common in lemon sprouts in pots, but it can happen to any lemon tree.

A lack of fertilizer can cause yellowing of the leaves. When it comes to fertilizing lemon seedlings, there are a few possibilities.

This is known as chlorosis. Nutritional deficiency will also cause growth to slow or stop. New leaves may curl downward, with the tips turning brown.

Testing the Soil

Before you fertilize lemon sprouts, you should test the soil. This is a simple process.

Once it’s completed, you’ll know if your soil is deficient in certain nutrients.

It will also reveal potential ph problems. An undesirable ph can make the nutrients in the soil unusable by the lemon.

If you are growing your lemon sprout in a pot, it’s easy to assume the soil is correct.

However, testing the soil is still a good idea, particularly if your lemon leaves are turning yellow.

Fertilizing Lemon Sprouts

There are a few options when it comes to fertilizing lemon sprouts. You can choose an organic fertilizer or a commercial variety.

If you choose a commercial fertilizer, choose a balanced fertilizer. It should have nitrogen, potassium, and phosphorous in equal amounts.

For the first year, fertilize once every 2 to 4 weeks. After the first year, fertilize every 4 to 6 weeks during the growing season.

Do not fertilize your lemon tree outside the growing season.

Kelp meal and fish meal are popular organic fertilizing options. However, to get the best results, you’ll need a more balanced fertilizer.

To make your organic fertilizer, you’ll mix four parts seed meal, one half the part bone meal and kelp meal, and one part dolomite lime.

Small, well-established trees require about one pound of this organic fertilizer. Larger trees will need more fertilizer.

Seedlings and sprouts only require a small amount of fertilizer.

 

Parasites

Parasites can also cause yellow leaves on lemon sprouts. If there are yellow spots on your leaves, this is due to spider mites.

Yellowing leaves can also be caused by aphids and whiteflies. Scale or mealy bugs also damage leaves. These bugs leave behind a white sticky substance.

Seasonal changes can also cause your lemon tree sprouts leaves to turn yellow. Lemon trees will often turn yellow when the weather changes.

They slow down their development throughout the cold months. Yellow leaves will appear.

This is a very normal event, and nothing to be concerned about.

Leaves on mature lemon trees and sprouts can turn yellow during spring and summer as well.

This is due to a major temperature change. If the lemon sprout has recently been brought outdoors, this can also cause its leaves to turn yellow.
