Cantaloupe Leaves Turning Yellow

Watering Problems


Overwatering can cause yellow leaves on the cantaloupe. The cantaloupe cannot handle too much water and it causes stress. Overwatering can happen when too much water is given to the cantaloupe or it can happen when heavy rains come.

A watering can or a garden hose can be used to water your cantaloupe but just give the tree the right amount of water. Check the soil moisture before watering the cantaloupe if the soil is dry you can water it but if the soil is moist you don’t need to.

There are ways to check the soil moisture like pressing your finger a few centimeters in the soil, pressing a screwdriver, or using a soil moisture meter. Any of those ways can be used to know the soil moisture and gives you an idea of when to water the cantaloupe.

A well-draining soil is also helpful to avoid waterlogging. Sometimes heavy rainfall comes to your location and you must make good waterways to prevent your cantaloupe from getting flooded. Too much water can cause root rot which makes leaves yellow but when it’s prevented the leaves are safe.

Lacking Water

Lacking water can also cause yellow leaves on the cantaloupe. Water is essential for the cantaloupe to grow well which helps it to grow healthy and able to produce more fruits. Water the cantaloupe regularly and make a watering schedule so that you know when to water your plant.

The cantaloupe needs more water when the weather becomes hot. With the right amount of water, it can make the plant cool and hydrated. The cantaloupe needs at least 1 inch of water per week.

Transplant Shock

Moving your cantaloupe to a new location can cause transplant shock. Transplant shock causes stress which can lead the leaves to turn yellow. Shock commonly affects mature cantaloupes and not those young cantaloupes.

You need to be careful in transferring mature cantaloupes because transplant shock may happen. Water the cantaloupe immediately just after transplanting. You will need to wait for a few days or weeks and monitor how the cantaloupe goes especially when they suffer transplant shock.

Usually, those young cantaloupes don’t get transplant shock. They just need to be watered after transplanting and they will grow just fine.  

Aging Cantaloupe Leaves

It is normal to see yellow leaves on any plant or tree. Commonly these yellow leaves are aging leaves. It is normal to see these kinds of leaves even on cantaloupes because it is part of their growth.

It is a cycle for the cantaloupe leaves to grow and then get old. The young leaves will grow and after a few weeks or months, they turn yellow, and eventually, cantaloupe leaves turn brown.

If there are only a few yellow leaves on the cantaloupe then probably they are just aging leaves but if there are too many yellow leaves you need to analyze and observe if there are other reasons causing the problem.

Nutrient Deficiencies

Nitrogen is an important nutrient needed by the cantaloupe to keep its leaves growing and staying green. Nitrogen deficiency causes yellow leaves on the cantaloupe and to prevent it from happening you need to make the soil rich in nitrogen. You can use a soil tester to check the soil and then apply the right amount of nitrogen.

The cantaloupe needs nitrogen because this nutrient helps the production of chlorophyll in the leaves. Chlorophyll helps the cantaloupe to convert sunlight into food which makes helps it grow better. Aside from nitrogen, Iron deficiency can also cause leaves to turn yellow on cantaloupe.

There are many kinds of fertilizer and some of them have nitrogen and iron along with other nutrients which is helpful for the cantaloupe to grow well if applied.

You Overfertilized Cantaloupe

You also need to be careful not to overfertilize cantaloupes. Too much fertilizer can burn roots and when roots get damaged it can cause yellow leaves. When roots are damaged the cantaloupe cannot get enough water and nutrients because the roots are not functioning well.

Avoid overfertilizing cantaloupes especially if you are using chemical fertilizers because they can burn cantaloupe roots.

If you are practicing organic gardening then you can use compost and other organic fertilizers. You can also add mulch to keep soil moisture.

Cantaloupe Is Lacking Sunlight

The cantaloupe needs sunlight to grow healthy and be able to produce more food. Grow the cantaloupe in a place where it can get a lot of sunlight so that the yellowing of leaves can be prevented. The cantaloupe needs at least 6 hours of sunlight per day.

Avoid growing the cantaloupe near tall trees because it may not get enough sunlight because those tall tress may block the sunlight. When the cantaloupe is getting consistent sunlight per day it will grow healthy and can give you a lot of fruits.

Weather Changes

Weather changes can also affect the cantaloupe which may lead to its leaves turning yellow. Even if the cantaloupe needs more sunlight, extreme heat is not good. Too much sunlight can affect the leaves which can make them yellow. Keep the plants hydrated when the weather becomes hot.

Pests And Diseases

There are pests and diseases that may also cause yellow leaves on your cantaloupe. You need to monitor your cantaloupe and see if there are pests and diseases that attack your cantaloupe. In that way, you can protect them and you can use pesticides or fungicides to get rid of them.
