Flowers that don't get root rot no matter how you water them - the more often you water, the more vigorously they grow

I have a friend who loves growing flowers and is a particularly diligent person, but because he can never keep his hands off his plants, he waters his potted plants at home every now and then, and many of his pots died from root rot caused by waterlogged soil. What a shame, so I recommended this flower to him, and he's been growing it quite well.
Calla lily
Calla lily, also known as water arum, is a bulbous herbaceous green plant. Its rhizome is rather thick and plump, and its leaves are not small either. When it blooms, the flowers rise a little above the leaves, and the flower shape resembles a horse's hoof, hence the name. When it blooms it comes in many colors, such as the common white, yellow and pink, as well as the less common red, purple and speckled ones, all very beautiful.
There has long been a saying that "you can't water a calla lily to death." Calla lily loves damp environments, so the potting soil must always be kept moist and must not dry out. During the growing season it needs frequent watering, and in the morning and evening you should spray water on the ground around the pot to increase air humidity and help it grow.
However, note that whether spraying or sprinkling water, you must avoid getting water on the flowers and prevent water from flowing into the leaf centers, otherwise it can easily cause soft rot disease of the leaves.
If you're a plant lover who wants to grow flowers, this is the right one to grow. Sometimes when you can't keep your hands off it and want to water, just go ahead - no more fear of root rot killing your plants.
Besides watering, when caring for calla lily you should also pay attention to these aspects.
A blooming calla lily must be given plenty of light. With enough light the leaves are more emerald green and the flowers bloom more vividly, making it look even more beautiful. When caring for it, try to place it on a windowsill, balcony or other spot with ample light so it can grow, but note that it dislikes direct strong sunlight.
Calla lily is also quite fond of fertilizer. Before the calla lily blooms, you can apply a compound fertilizer containing phosphorus, potassium and nitrogen once every half month, but note that when fertilizing, don't pour the fertilizer water on the leaf surface. If it accidentally drips on them, be sure to rinse immediately with clean water to avoid the branches and leaves rotting.
One more thing to note: the calla lily must be placed in a ventilated environment, and it cannot be placed where there is smoke, such as a room where people often smoke. If smoke covers the leaves for a long time, it can easily cause yellow leaves and affect its ornamental value.
