Growing orchids is not difficult. These are plants that adapt very well to living at home, as the temperature they need to thrive is mild, even if some species tolerate the cold very well. The important thing is that, of whatever type our orchid is, it has the possibility of benefiting from the thermal excursion: there must be a certain difference between the temperature of the day and that of the night (even four or five degrees less are enough) . The alternation of temperature allows orchids to develop more numerous and healthier flowers. Unlike many other plants, with orchids one must be particularly careful during the summer, when temperatures rise. The heat could indeed be very harmful to the orchid. It is advisable to place them in a shady place, and to water them early in the morning, when the temperature is still not too high. During the course of the day, it is advisable to spray fresh water on the orchid several times. If the plant is inside the house, it is advisable to keep it in what is the coolest and most shady room. Orchids need natural light to survive well, but they must not be exposed to direct sunlight: the leaves could get burned, and thus become prey to fungi and parasites. Orchids need air exchange: it is sufficient to open a window to create the slightly ventilated climate that these plants need. Do it if the temperature allows it a few times a day: your orchid will benefit from it.
To cultivate an orchid well, water is very important: not only in terms of quantity, but also its quality. First of all, it must be borne in mind that orchids need moisture: the humid climate is what made them thrive in nature. Every morning it is recommended to wet the soil (without touching the leaves or the stem of the plant), but depending on the climate, the irrigations can be suspended for a certain period of time. Particularly in the coldest months, before watering the orchid wait for the soil to be dry, and have no moisture residue. But when we water the orchid, special attention is also required to the type of water we use. Water with too much limestone is not good for this type of plants, as too much calcium would be very harmful for orchids: avoid using tap water, if it is very hard. If possible, use rain water for your orchids, taking care to store it in a covered plastic container protected against atmospheric agents. This tip of water has all the elements necessary for the life of the orchid, without having too much calcium. Otherwise, use purified and very sweet water, add a few drops of liquid orchid fertilizer. Even water that is too sweet can cause damage to the orchids, making the leaves dark.Fertilization
The use of a special fertilizer for orchids is recommended, as this type of product usually contains all the elements these plants need. Phosphorus, potassium and nitrogen are indispensable for orchids, which provide the elements necessary for the growth of the different parts of the plant. Fertilization is important as orchids are home plants, which are kept in pots: the soil from which to absorb nutrients is therefore limited. The liquid fertilizer can be easily dissolved in the water that we will give to the orchid during regular watering: avoid exaggerating with the quantities, and respect the dosage on the package. The orchid can be fertilized once every twenty days during the winter and spring months, while these operations will have to be made less frequent with the arrival of the winter season.
Grow orchids: Repotting
Another fundamental operation to be carried out when deciding to cultivate an orchid is repotting, which must be done in late spring, whenever it is noticed that the roots have grown enough to fill the current vase or every three years. Proceed by removing the plant from the pot and washing the roots under running water. The roots will have to be controlled, and those that are diseased or dried will be cut away. It is advisable to soak them for a few minutes in a special disinfectant solution, to make them less susceptible to fungus. The new vase must be made of transparent plastic (so that the roots also benefit from sunlight): on the bottom you can put pieces of cork, to create water drainage. The pot is then filled with the appropriate soil by half: at this point, the orchid is placed, and another soil is added and compacted next to the plant.
