When, how and how much to water Anthurium
Anthurium is a plant native to tropical regions where the climate is perpetually humid and very hot. For your well-being at home, you must try to recreate this type of habitat, especially during the winter when the heating system is active and the air can become very dry even for people. In this case, the environmental humidity can be increased by frequently vaporizing the Anthurium foliage with demineralized water, an operation to be avoided during flowering. In the summer it should be watered abundantly, but without exaggeration, the important thing is that the earth in the pot never remains dry. A good trick is to place in the saucer of expanded clay or gravel, in this way the roots will never be in direct contact with water but this will always be available to the plant, even simply as water vapor. To protect the roots you can also use moss to be kept constantly slightly humid. For watering it is ideal to use rainwater, while dusting the leaves with a damp cloth will allow them to breathe better.
How to cure Anthurium
Keeping Anthurium between 16 and 18 ° C and ensuring the right amount of humidity is one of the few treatments that this plant requires. It is sensitive to cold and, in particular, to drafts: in summer, therefore, outdoor life is welcome, but in autumn, when the temperature changes start to be abrupt, it is good to repair it. The temperature, from October until late spring, must not disturb the vegetative rest, settling around 13 ° C: in this way, subsequent sparse and hardly blooms are avoided. Every two and a half or three years Anthurium may require a larger pot, at least when the roots come out of the holes below the pot. In this case it is good to proceed with decanting, preferably at the end of winter, and you can use the same soil as the orchids, soft and porous and with ideal pH. The flowers may need a brace, as the weight tends to fold the stem. It is a herbaceous plant, therefore it cannot be pruned, but it is better to eliminate the dry and yellowed leaves. Finally, to obtain new seedlings, simply divide the head at the time of repotting, making sure that at least one group of roots corresponds to each bud.
