Watering Orchids

THE WATERING frequency is one of the most difficult and delicate operations to master in the cultivation of orchids. In general, the orchids greenhouse must be moderated and you should always be aware about the moisture levels in the substrate.

The substrate must be slightly humid but not overflown. Orchids love humid substrate and can not stand steady water in the deep of the vase. So never use plates under the vase. Accumulated water on the deep of the vase rottens the roots and this is fatal for your plant. Hanging your vase or treefern plate at 45 degrees helps the drainage as so does the use of small rocks in the end of the vase.

Water (at night) more during the hot summer days, and less during the cold seasons. Each genus or even species has its particular needs but in general, after allowing the container compost to dry out before any watering, one should water in abundance until the water flows freely out the container drain holes.

Much humidity also favors the appearance of fungus and nematoids, that have the capacity to enter in dormancy for months or years in the vases. From there the predilection of the culture of orchids in aired places.

The water must be sprayed at the beginning of the morning, once a week if the plant will be in humid place. The sprayer use is the ideal, therefore watering cans and hoses throws too much water, passing fungus or virus of one plant for another one.

In some cases, it is recommended before the irrigation to raise the vase with care and perceiving its weight, to know if the irrigation is necessary or not. In imprisoned plants in plates of treefern the irrigations are usually more frequent, since the drying time of the plate is faster.
