Can a cactus be sustained by water? Tips for the care of hydroponic cacti.

Can a cactus survive by watering alone?For most women, the explanation of whether a cactus can survive by watering alone and the tips for caring for a hydroponic cactus in the aspect of green plants and flowers, let's learn about them together below.In the common sense of most people, cacti should not be watered too much, often watering once every one or two months, less is better than more. However, if not watered for too long, the roots of the cactus may shrink and dry up, and it will not grow. It may not change even after a year and a half, looking like a fake one.If a cactus can be hydroponically cultivated, then there is no longer a need to consider watering. Even if the roots are soaked in water, it can grow normally, so what is there to worry about!Hydroponic cultivation of a cactus does not mean placing the cactus directly in water to grow, as it will rot quickly. Some operations need to be performed to allow the cactus to grow aquatic roots, which can absorb nutrients and water from the water to meet the growth needs of the cactus.Now, let's get to the point. How to make a cactus grow aquatic roots? Follow the steps below, and it can be transformed from soil cultivation to hydroponic cultivation in half a month.【1】Trimming the RootsFirst, remove the cactus from the pot and clean the soil thoroughly, which can be washed with water, but try to avoid getting the body of the cactus wet. After cleaning the roots, use clean scissors to cut off the fine rootlets, leaving only a small part of the thick roots, or even cutting them all off is fine.【2】Air-dry for a WeekThe purpose is to allow the trimmed root wounds to dry and heal. It must be placed in a well-ventilated area. In a well-ventilated environment, the cuts dry faster and are less likely to become infected. Don't worry that a week is too long and the roots will dry out. It will be fine even after ten or half a month. The roots of the cactus are not that fragile, and the longer they are dried, the stronger their desire for water will be, and the faster the root growth will be in the later stage.【3】Guiding Root GrowthAfter a week, if the roots are completely dry and not infected, choose a small-mouthed container (with a diameter smaller than that of the cactus) or a planting basket. Place the cactus above the container mouth, fill the container with water, and the water level should be just enough to touch a little bit of the roots. Really just a little bit, that's enough, not too much water. In just three or four days, you can see white aquatic roots growing out and extending into the water. Throughout the process, it's best not to let the body of the cactus touch the water, including when changing the water later.【4】Post-managementAs the aquatic roots become more and more, and longer, lower the water level to expose the upper part of the aquatic roots to the air, so the roots will not rot due to lack of oxygen.Later, change the water every two weeks, and use nutrient solution to make the cactus grow faster. (You can prepare a clip, as I do it with my bare hands... it really hurts...)❗️❗️❗️Note: Hydroponically cultivated cacti are still cacti, so their other growth habits remain unchanged. They still need to be exposed to sunlight and well-ventilated. If they lack sunlight for a long time, they will easily become elongated, and the cactus may become a cactus column.The above is a comprehensive method of explaining whether a cactus can survive by watering alone and the tips for caring for a hydroponic cactus, hoping to solve your problems with green plants.
