Desert cacti prefer dryness between watering and if you don’t allow this break, you run the risk of root rot, which results in a brownish discoloration at the base of the stem. To avoid this problem for indoor cacti, let the soil dry at least between 4 to 5 cm before watering again.
Can you revive a brown cactus?
To revive a dying cactus, recreate the conditions of the cactus’s natural environment by watering only when the soil has dried out completely, locating the cactus in full sun and repotting the cactus in well draining, gritty porous soil.
Will a brown cactus turn green again?

How often should cactus be watered?
Water your cactus only when the soil is completely dry. During the warmer seasons, this could be every 10 to 14 days. Cacti will go dormant starting in the fall and until the end of winter. During their dormancy period, they need less watering, when the soil is completely dry.
How can you tell if a cactus is dehydrated?
The best way to check if your cactus needs water is to use an inexpensive moisture gauge, or by touch. The soil should be completely bone dry before adding more. If the meter reads dry (at 1 on the scale), or you don’t feel any moisture when you stick your finger down at least 2”, then it’s time for a drink.
How do you tell if a cactus is over or under watered?
The stem can show a change in color. The bottom of the cactus stem tends to turn brown or black and has a slimy feel when touched if it is receiving too much water. The cactus tends to look stale and appears unhealthy and rotten. These are signs of decay in the cactus caused by overwatering it.
Can a cactus survive overwatering?
Cacti aren’t just drought tolerant – they need some drought to survive. Their roots rot easily and too much water can kill them.
How do I stop my cactus from overwatering?
Use pots with proper drainage. Holes in the bottom of pots allow excess water to quickly drain. Porous materials like clay, concrete, and terracotta also wick away some extra moisture and are often ideal for succulent plants.
Can an overwatered plant fix itself?
Overwatered plants can sometimes recover on their own, but it depends on the plant and the extent of the overwatering. If the roots have rotted, the plant will likely not recover. However, if the overwatering has only caused the leaves to wilt, the plant may be able to bounce back.
What are signs of root rot?
Signs of root rot are slow growth, mushy stems, and wilting, yellow, distorted leaves (especially when the plant has been well watered, as wilting leaves can also be a sign of a dry plant). Usually the soil will smell rotten and the roots will appear to be reddish brown.
Should I repot if I overwatered?
It’s important to get as much remaining old, wet soil out of your plant and plant roots before you repot your plant. Old soil could potentially harbor mold, which can cause mold growth on your plant once it’s been repotted; so make sure as much of it is gone as possible before you start adding the fresh soil.
How do you dry out an overwatered plant fast?
CPR for Drowning Plants

Does sugar water help dying plants?
Since we now know that using sugar in our waterings won’t help plants effectively, we must also consider the potential harm. The number one effect that most studies have found is that sugar can reduce the plants’ ability to absorb or take in any water.
