1.  Overwatering CrotonCroton Leaves Turning Yellow

One of the major reasons for turning the plant leaves yellow is overwatering. Of course, we are all aware that plants require water, and insufficient water might damage your plant. But, sure, it could also be dangerous to overwater your Croton. If you overwater the plants, you virtually drown them, and they can cause roots to rot.

How to fix Overwatering

You will need to smell the plant to check whether the water is too much. If you notice any smell of mildew, it could imply that the roots of your plant rot.

In this scenario, change your plant’s container to one containing superior drainage and change the watering schedule. Let the soil dry a little between the watering if you are overwatering your Croton.

2.  Insufficient lightInsufficient light

Crotons are indigenous to exotic places with plenty of light as well as sun. So if you store it in a gloomy corner of your residence, the plant won’t flourish. Also, crotons usually lose a little of their color in wintertime and light, so if the croton leaves look a little yellowish or faded, they might not be getting sufficient light.

How to fix insufficient light

A simple solution to solve insufficient light is to shift your plant to where it receives more light. If you reside in a warm and sunny place, ensure you take your Croton plant and then let it absorb in the bright sunshine.

However, it doesn’t imply that you throw your plant outdoors, and all the problems in your plant will be fixed. Croton could be a bit irritable, and they don’t like movements. So, first of all, harden the plant by keeping it out for a few hours. Then, put the plant first in a sheltered area and allow your Croton to adapt to external conditions like a breeze, brighter sunlight, and varying temperatures before permanently leaving it outdoors.

Planting your Croton outside in a cooler area is not a fantastic idea. Crotons are unable to resist temperatures below 30F. So instead, ensure you place your Croton in the vicinity of your sunniest windowsill and observe its brilliant colors flourish.

Occasionally, because of intense direct sunshine, the Croton’s leaves might change their color. The above solutions will not work in this circumstance. When this happens to your Croton, attempt to provide a shield between the sunlight and the Croton plant using sheer curtains or transfer it to a point where the sunlight doesn’t get as severe.

a)  Simple way to combat spider mites

To fight spider mites, wash the afflicted plant from a pipe or a hose with flowing water. Wash the plant as much as possible and repeat it until it is effective multiple times. You may also add natural predators such as ladybugs. You have good advice on predator species while visiting your local nurseries. Another alternative is the application of chemicals like pesticides to eliminate spider mites effectively.

b)  Combatting mealybugs

To combat mealybugs, you can pluck and destroy the damaged areas of your plant. You can also visit your local gardening shop and acquire some pesticides. If you wish to take the non-chemical method, you have an option to get predators, like ladybird beetles and green lacewing, but contact an expert to find the correct sort of predators to help your mealybugs.

4. Changes in temperatureChanges in temperature

Croton thrives in warm and humid environments, and it is the climate in which they thrive. Plant species are not fans of cold and coarse settings, and under these conditions, they will suffer. In addition, the temperature can impact the appearance of your plant, and crowns exposed to cold and sunny weather tend to lose momentum and turn their leaves yellow.

Fixing temperature changes

Make sure your Croton is kept happy by placing it in a warm and humid environment. Assess your window and door to ensure that no breeze comes from outside blows on your Croton plant. If this is the case, transfer the plant to a different place.

It may be bright and humid outdoors, but it could also be cold indoors for the Croton plant if you leave the croton inside when your air conditioning system is running. Slightly take it out for a few hours, till your croton is exposed to external conditions, then permanently relocate it outside.

Nevertheless, if it isn’t warm outdoors, but you just love a cold place, try moving the croton to the air-conditioned room and leave it by the windows to obtain the sunshine it requires.
