Answer 1

Your cactus has scummed to a fungal disease of damping off. It is often brought on by over watering , but the disease is caused by a fungus. You can reduce the incidence of damping off by adding a fungicide such as No-Damp to the water you use. It is probably too late to help your cactus at this point but keep it in mind in the future. I would recommend that you propagate your cactus by a cutting.
Those types of cacti that are columnar, pad-forming or those with segmented stems such as a Christmas cactus are easily started from cuttings. As with seed, spring is the best time to take cuttings, as most cacti will be emerging from their winter rest at this time and initiating new growth. The size of the actual cutting taken can be quite variable. On a Christmas cactus, a couple of stem segments may be used, with a total length of a few centimetres, while on some columnar cactus plants, a single cutting may be as long as a meter. An important point is that the plant that you are taking the cutting from should be in as healthy a condition as possible. Take your cutting from as far above the rot as you can.
When taking a cutting from a stem section, use a clean sharp knife. If you are taking several sections from one long stem, you must remember which was the top and the bottom of each piece, because a stem piece that is planted upside down will not grow. A simple way of keeping track of the top and bottom is to cut the bottom of each segment on a slight angle, and the top straight across. A single oval pad from a pad-forming cactus makes an ideal sized cutting.
The primary problem encountered with cactus cuttings is the development of fungal soft rot. This condition begins at the cut surface and eventually reduces the entire cutting to a slimy mass. Two techniques are recommended for avoiding this problem. The first is to simply allow all fresh cuttings to sit in a warm dry place for from 1 to 14 days before they are placed in the rooting medium; the larger the cut surface, the longer they should be allowed to dry. During this time, the cut moist surface will form a dry callus which is far less prone to rot. Although it sounds slightly alarming to leave a newly taken cutting sitting exposed for several days, remember that a cactus is able to survive periods of drought. As long as the cutting is not noticeably shrivelled, it is probably alright to leave it dry. Newly cut stem segments may also be dipped in garden sulphur before planting to prevent the onset of soft rot.
Cuttings will root in a standard well-drained cactus mixture if provided with bright light and cool temperatures for several months. After you have prepared your soil mixture it is a good idea to partially sterilize it by placing it in a conventional oven on medium heat for about 45 minutes. Although the cuttings may not have a developed a root system, resist the temptation to keep their soil any wetter than you would a normal cactus plant. The wetter the soil, the more likely the cuttings will rot. Best of luck in saving your cactus.

What has occured is called Damping off, Rotting at the soil line usually means too much watering...back off from watering ,,yes if you allow it touch the soil it will take root, and yes the surviving parts can grow to be other cacti.
Cactus and all Cacti are succulents that have adapted to an environment with little or no water,,Nature has modified these plants in a way that helps them retain moisture,,be carefull of too much watering.

Answer 3

stop giving it water for a few days, don't cut it until the rot falls out, it will in a few days. Put in a pole and secure the cacti to it. It will make more little baby cacti... good luck oh and talk to it.

Answer 4

It sounds like that you need to repot the plant. It sounds like it needs a bigger planter!
