Cactus characteristics

The cactus or cactus plants are among its main features its roots and thorny stems and leaves that either do not exist or are very small or shaped spine. They are plants with roots that cover large areas, usually at a shallow depth, in order to absorb as much moisture as possible due to the low rainfall in their most common environments.

Knowing when to water a cactus is another of the most important problems in the care of cacti in pots or in the garden . The roots of these plants spread a lot, but at the same time they are fine and very sensitive to rot: an excess of humidity has a good chance of making your cactus sick, being in some cases it necessary to prune affected areas to save it. If you ever see him sick, here are tips on how to revive a cactus .

The water needs of these plants are much lower, so water only when the substrate has completely dried even below the surface. Generally, this will occur once or twice a week in warm months, and up to every 15 days in cold months. Some cacti can even stop being watered altogether during winter.

If you ask yourself ” how do I know if my cactus needs water ?”, The answer is easy to see by looking at its stem or the base of it. If it is wrinkled or looks deflated instead of smooth, the plant is consuming its water reserves and needs more watering.

How to transplant a cactus

In any of these cases, it is necessary to take into account when a cactus can be transplanted , which must be done during the summer or some especially dry season, since in this way the plant runs less risk of being attacked by fungi or suffering more stress than necessary during the process.

It is also important to use gardening gloves, or gloves thick enough so as not to hurt us with their thorns, and remove the soil from the roots of the cactus, being very careful not to damage them. You can help yourself with low pressure water for this. This method is also very valid for transplanting those suckers that many cacti produce and that are an excellent way to reproduce them easily and quickly.
