The most common reason is light. Almost all types of jades will get red tips and margins when they receive plenty of light. But the color change can be caused by temperature, improper watering, fertilizer, or the soil.
White spots on your Jade plant can be caused by excess salt in your tap water. If the water does have excess salt, the plant will expel the salt through the leaf pores. This will not harm your plant, but you may want to consider using filtered, rain, or distilled water if you want to avoid this spotting.
Spider Mites
They spread with ease from an infested plant to another and can survive by sucking up sap from the leaves of the jade plant. Aside from the visible white spider-like webbings on the plant's leaves, spider mites are known to cause little dark spots on the plant's foliage.
When a Jade plant receives full sun the tips can turn red. Watering-Allow the plants soil to dry out between waterings. If the leaves become wrinkled looking then the plant needs water.
The reddening of Jade plant leaves is triggered by strong direct sunlight. The sugar crystals that are present in the leaves react to the sun and cause the discoloration. That is completely fine.
If your jade plant is given more water than it can use through its normal processes, small blisters form in the leaves and cells rupture, followed by drying of the leaf surface and the formation of a rough-textured, gray-brown patch on the leaf, called corky scab.
A healthcare provider may think you have mites based on your health history and a physical exam. Intense itching and many small, red bumps, like pimples, are seen. Burrows may also be seen. These look like thin, wavy lines.
Stems and branches collapse. The interior tissues are soft and mushy. Discard affected plants. Scabby or corky areas develop on leaves.
Eggs (3-5 Days) – Spider mite eggs are small and round, and appear on the underside of leaves, usually in small clusters of around 20 eggs. These eggs can also overwinter on outdoor plants and begin to hatch as temperatures warm.
How to Water Jade Plants. Jade plants are succulents (they hold water in their leaves), so they don't do well when sitting in constantly moist soil, so let the top 1 to 2 inches of soil dry out between waterings. Indoors, this will probably mean watering once every 2 to 3 weeks—but be sure to check regularly!
Jade needs lots of light—at least 4 hours per day in a south-facing or west-facing window. Keep soil moist but not wet during the growing season (spring and summer) and let the soil dry out during the dormant season (fall and winter). Don't splash the leaves when you water.
Changes to the leaves are the first sign of an overwatered jade plant. Leaves can turn yellow and droop, and may eventually brown and drop off. Other signs include the leaves and stem becoming squishy and soft. The whole plant may also appear droopy.
What are the disadvantages of Jade plants. The only disadvantage of the Jade plant is that the leaves of the plant can tend to hold onto excessive water. Due to this, they become soft and mushy and fall off the plant.
Jade plants are sun-loving succulents and do best when they get plenty of bright light. However, too much sun can cause the leaves to turn red or brown. If your jade plant has been sunburned, move it to a shaded area and give it time to heal.
To encourage health, harmony and thriving business, place the Jade plant in the east direction. And if you wish to promote creativity and children's luck, it is recommended to set it in the west direction. Keeping it either in the southeast corner of the room or your desk is highly favourable and auspicious.
Spray mineral-free water on the leaves to create a moist environment that will make them disappear. A simple hand-spray is enough for this. Rainwater is a good example, but demineralized water also works. Hosing down & showering also dislodges red spider mite.
Where do red mites come from? Red mites occur in the wild where birds roost, often hidden in the cracks of tree bark, coming out at night-time to feed.
Springtails, also known as snow fleas, thrive in wet or damp areas, where they gather in large clusters. From far away, they can look like little specks of dirt or particles of pepper in the snow.
Mealybugs (Pseudococcidae) are the most common pests of jade plants. These small, white, wax-covered insects sport filaments on their sides, and sometimes even tails. They exude honeydew, which attracts black sooty mold that looks, frankly, quite ugly and dirty.
How to tell if your jade plant has powdery mildew. Powdery mildew is a fungal disease that is harmful to jade plants but doesn't kill them. You can identify it as white or gray spots that commonly appear on the lower leaves. As its name suggests, these patches often look powdery, like flour, or fuzzy, like mildew.
The most common causes of a dying jade plant are problems with watering, light conditions, or pest infestation.
Color is one of the most important factors in determining the value of jade. The most valuable colors are green, white, and lavender. The more intense the color, the more valuable the stone. Jade that has been dyed or treated is usually a uniform color with little variation.
