Cactus Turning White Cause and Care Guide

Your cactus turning white maybe because it’s dehydrated. Dehydration occurs when plants lose water faster than they’re able to replace it. This happens when there isn’t enough moisture in the soil or when too much water is applied. If you notice that your cactus has turned entirely white, it needs to be watered immediately.

If your cactus loses nutrients, it might lack one or more essential elements like calcium or magnesium. Calcium helps maintain cell walls and strengthens stems; magnesium aids in photosynthesis, growth, and energy production. You can supplement your plant’s diet with liquid kelp, alfalfa pellets, bone meal, greensand, or rock dust.

Insect infestation is another reason why your may cactus turning white. Mites, aphids, mealybugs, scale insects, and thrips feed off the plant’s sap. These pests can be controlled with insecticidal soap sprays, such as neem oil, pyrethrin spray, horticultural oils, garlic extract, boric acid, and diatomaceous earth.

Fungal infections can also lead to white patches on your cactus. Fungi thrive in warm weather and moist conditions. They grow best in dark areas where temperatures remain above 80 degrees Fahrenheit. To prevent fungus from spreading, keep your cactus out of the direct sun and away from excess heat.

A few other possible reasons your cactus turning white include exposure to harsh chemicals, such as bleach, ammonia, or excessive light.

Cactus Turning White: How To Treat Cactus Frost Damage

Cacti are beautiful plants that thrive in warm climates. But many cacti species are susceptible to frost damage. If you live in an area where temperatures drop into the single digits, it’s essential to know how to treat frost damage.

Frost damage happens when cold temperatures air freezes water droplets on plant leaves. This causes the cells to expand, which leads to tissue death. The frozen moisture expands when the weather warms up again, causing the cell walls to break down. As the plant grows, the damaged areas become brittle and weak.

The best way to prevent frost damage is to keep your plants indoors during the colder months. You can move your potted cacti outside during spring and summer. Or you can purchase a small greenhouse to protect your plants from freezing temperatures.

If you must move your plants outdoors, make sure you cover them with something like burlap sacks or plastic tarps. These materials help trap heat inside the pot. And don’t forget about mulch. Mulching around the base of your plants will insulate roots from the ground and help maintain soil warmth.

Once your plants are safely out of harm’s way, use a sharp knife to cut away damaged parts. Then soak the affected tissues in lukewarm water for several hours. Afterward, apply a light coat of fertilizer to encourage healthy root development.

A soil moisture meter measures the amount of moisture in the soil. This information is helpful because it tells you whether or not there is enough moisture in the soil to support healthy growth. When purchasing a soil moisture meter, look for one that reads dry and wet soils.

Cactus Turning White: Use An Ice Blocker

If you live in areas where temperatures drop below freezing, you’ll want to cover your plants with something that insulates them from the cold temperatures. An ice blocker is a great option. These devices work by creating a barrier between the cold temperatures air outside and the warm air inside your home.

3. Clean it regularly. Dust buildup can cause problems such as fungal infections, so you’ll want to keep your cactus free of dirt. Use a soft brush to gently scrub off any dead skin cells.

4. Don’t overfeed it. Cacti are sensitive plants, and too much food can lead to root rot. Make sure you feed your cactus once every month or so.

5. Prune it. As long as you prune it properly, no harm will be done. Just remember to cut back any branches that grow into the light source.

Cacti like dry soil conditions. They don’t like being kept too wet, either. Soaking your plants in water every day isn’t necessary. Instead, give them just enough water to moisten the soil around them. This way, they’ll have access to moisture without drowning.

Feeding Your Succulent Plants Too Often

Cactus Has Been Watered Too Much or Not Enough

Cacti are plants that grow in arid areas such as deserts, mountains, and rocky places. They thrive in dry conditions because they don’t require much water. But too much water or too little water can cause problems. If you over-watered your cactus, it could die. And if you under-watered it, it could fade up. In either case, it turns white spots.

How To Treat Cactus Overwatering and Underwatering

Cacti are very sensitive plants. They require proper care and attention. To grow healthy cacti, it is important to know how to treat overwatering and underwatering.

Overwatering is caused by too much water. This occurs when the plant receives too much water during the growing season. This usually happens because of high humidity levels. A good way to prevent overwatering is to keep the air around the plant cool. You can open windows and doors to let some air in. Also, ensure there is no standing water where the plant is located.

A lack of water causes Underwatering. This occurs when there is not enough water given to the plant. Keep in mind that cacti prefer slightly moist soil. Make sure that the cactus soil does not become completely dry.

When watering cacti, use a spray bottle rather than a hose. Spray the soil evenly and avoid getting any water on the leaves. Do not allow the cactus soil mix to dry out completely.

How To Prevent Cactus Overwatering and Underwatering

Watering too much or too less can cause root rot, especially if you keep cacti in pots. You want to ensure that the cactus soil is dry before adding more water. If you don’t wait until the soil is completely dry, you could overwater or underwater your plants. This can lead to root rot.

Cacti like regular water about once every week, depending on how hot and humid it is outside. But you shouldn’t let the pot sit empty for long periods. Give the container a good shake when you’re ready to water again. Then fill the bottom half of the pot with water. Let the water soak into the cactus soil mix for about 15 minutes. Afterward, drain off the excess water. Repeat this process twice more.

If you have a large pot, you might want to use a hose attachment to help you water. Otherwise, you’ll have to pour the water directly onto the soil. Be careful not to splash yourself while doing so. Once you’ve finished watering, allow the soil to dry out thoroughly before filling the pot again.

Other pests include aphids, leafhoppers, mealybugs, scale insects, spider mites, thrips, whiteflies, and weevils.

Most moths lay eggs on the underside of leaves. Eggs hatch into larvae, which feed inside the plant tissue. Larvae grow up to several inches long. When mature, they pupate and emerge as adult moths. Adult moths fly around looking for food and mates. Their feeding habits vary depending on the type of moth. For example, some feed on pollen while others feed on nectar.

The most common types of moths found in homes are clothes moths, carpet beetles, codling moths, corn earworms, cotton bollworms, fruit flies, house flies, lace bugs, light brown apple moths, mealworms, nut moths, oriental cockchafer, peach tree borers, pine sawyers, rose midges, silverfish, tussock moths, tobacco budworms, tomato hornworms, and wax moths.

Why Cactus Turning White: Cactus Is Rotting

If a cactus turns brown on the outside and soft inside, it might suffer from some kind of disease. The salt buildup causes a rotten cactus to become white because it provides an ideal environment for bacterial growth.

Cacti sometimes develop root rot, making it hard for them to absorb water from their roots. Because of this, they begin to get drier from the sun or rain, which leads to more rot because there isn’t enough moisture for their skin to keep them healthy.
