Should I water my cactus with warm or cold water?
Cacti prefer warm water, and don't absorb water that is too cold for them. So, the perfect water temperature for watering cacti is around 86-104 degrees Fahrenheit (30-40 degrees Celsius). When you pour the 86-104 temperature water, it becomes cold after the contact with soil.
Watering is an essential part to how well your cacti or succulent grows. Overwatering will stunt growth, but under-watering causes shrivelling. Tepid rainwater should be used for watering, rather than tap water. This is because the minerals in tap water build up in the soil and can cause deposits on the leaves.
DON'T OVER WATER
Drowning a cactus is actually one of the most common causes of cacti death. Make sure you feel the soil before watering to check it's completely dry. If it isn't, wait a few days. To avoid the dreaded root rot, get a spritzer.
Cacti have a hard time absorbing water that is too cold for them so warm water is best. The right water temperature is between 30 and 40 degrees Celsius. The water will quickly cool down when in makes contact with the soil.
No, it's never a good idea to spray a cactus with water. They have very low humidity needs, and moisture left sitting on them can cause rot and other diseases.
When most mixes are that dry they do not take up water readily. We have found a good way to water a dry mix is with ice cubes. They release water very slowly as they melt and the 'soil' has time enough to absorb the water.
Some cactus species can go for two years without water. The indoor varieties, however, do require more frequent watering, depending upon the species.
Many home growers have unknowingly caused damage to plants when watering cacti and succulents with tap water. If your tap water is from a municipal source (city water), it likely contains chlorine and fluoride, neither of which have beneficial nutrients for your plants.
The optimal time to water is about 10:00 PM after the hot summer ground has had a chance to cool off and gas exchange is fully active. However, potted agaves and cactus can be watered earlier if they are not superheated by the afternoon sun.

Older Christmas cactus plants in particular are very sensitive to this — the leaves may die. You can counteract this with coffee grounds as fertilizer. If the pH value of your soil is too high, you can also achieve a balancing effect with coffee grounds.
It's not difficult to check if the soil is dry. The easiest way is to simply stick your finger in the pot. Make sure you go down at least two inches (often times the surface can be dry when the dirt underneath isn't). If it feels wet, damp, or even a little colder than the surface – don't water.
In the wild cacti can live for hundreds of years. Indoors they may survive for 10 years or more. The trouble with old ones is that every single knock, scratch or blemish they get stays with them, so they tend to look less appealing as they get older.
Most cacti species don't need exposure to direct sunlight to survive.

You don't get 'water' from cactus; you get a stomachache and vomiting. In movies, you see a cowboy lop off the top of a barrel cactus—a big, beach ball-shaped cactus—dip his ladle in and get a drink of water. That's not water, though. It's a noxious fluid that's very high in alkalis.
Most of the desert plants such as some Cactus, the species of Oenothera like the evening primrose, Cereus etc. bloom at night. A prominent factor is that the flowers of these desert plants get pollinated during night times. The night-flying insects and moths help in the pollination, and thus to increase reproduction.
In general you want to cut above any rot so that the fresh cut will be clean, no brown spots. Spray with hydrogen peroxide to help it heal, and let it callous over for a week. Then you will want to plant it in dry fast-draining cactus soil and not water for another 2 weeks.
Generally aerial roots will form on a succulent that isn't getting enough water and often when it's in a humid environment. Succulents absorb water through their roots from the surrounding air. That is why having a soil with large particles is really important for the health of your succulent.
We recommend using a herbicide that contains picloram which has the potential to destroy 76 percent to 100 percent of prickly pear and certain other types of Cacti. Take an ax and damage the plant. This will help the herbicide to seep into the Cactus better. Prepare a herbicide spray mix of Picloram in a sprayer.
The barbed cactus spines don't actually jump, of course. But they detach easily from the main plant and hook tenaciously — sometimes painfully — into people who get too close.
They get by with little water, but not no water. Here's a rule of thumb when watering cacti indoors: let them completely dry out, and then water again. It's best if the pot has at least one drainage hole, so all the excess water flows right out the bottom of the pot.
Keep them on the window sill
The best place to put a cactus as a part of your home décor is on the window will of any room. Since cacti thrive in bright, sunny conditions, you do not have to worry about the amount of direct or indirect sunlight that reaches the plant.
Cacti need dormancy to bloom. The rest period usually takes between two and four months when the temperature is under 15c. During this time, withhold water or fertilizer and move the pot to a cool place with plenty of sunlight. Place the cactus in a bright position where they can get plenty of sunshine.
If you're a chronic over-waterer and find yourself with a squishy and browning cactus, don't despair: You can rescue your plant if it has any viable green tissue. After removing all of your damaged roots and stems, you can enjoy your healthy comeback plant!

Its stems are thick with a lot of room for storing water, and with a protective covering that keeps the stored water inside. Some cactus species can go for two years without water. The indoor varieties, however, do require more frequent watering, depending upon the species.
Top watering can help flush excess salts and mineral deposits to the bottom of the pot and eventually out of the drainage holes. Constantly bottom watering will keep these salts and minerals in the potting mix, so top watering can help keep the root system of your plants healthier.
Don't mist desert cactus. They are not native to regions where surface moisture and humidity is prevalent. Instead, they reach deep into soil to harvest moisture left over from the rainy season. Jungle cacti are a bit different and thrive with some misting.
