Watering method of Phalaenopsis

Phalaenopsis watering
The key to cultivating Phalaenopsis lies in the supply of water. The suitable environment for the root system of Phalaenopsis should be as follows: warm (15-30 ℃), proper humidity and ventilation, weak acidity of pH value, refreshing fertilizer, sunshine (photosynthesis of some deciduous or leafless Phalaenopsis roots). Phalaenopsis in the wild, by the root climbing on the trunk or rock, leaves and flower stems drooping, upside down growth. Abundant Rain Water keeps the roots from feeling too dry. in fact, the roots of Phalaenopsis are not afraid of water and moisture. So we use flowerpots.

Four reasons for the failure of Phalaenopsis family cultivation
1. Watering too frequently: friends who cultivate Phalaenopsis are always worried about the lack of water, regardless of whether the cultivation medium is dry or not, watering every day, resulting in serious root rot. 2. The temperature is too low: usually the flowering plants of Phalaenopsis are on the market in early spring, and they are generally appreciated in the living room after buying them home. Although the daily temperature in these places is enough, the night temperature is a little too low. On the other hand, most of the professionally cultivated orchids are in well-equipped greenhouses. By contrast, the temperature and humidity at home are not enough, so the plants tend to grow.

Prevention and control of several diseases of Phalaenopsis
Anthrax occurs seriously in high temperature and humidity, forming brown-black round spots and gradually expanding outward. The occurrence of the disease can be controlled by uniform spraying with 800 times of Prike solution, once every 5 days, for 3 consecutive times. The symptoms of soft rot are leaf base rot, corm rot and mildew bacterial smell. Methods of prevention and treatment: agricultural streptomycin sulfate was sprayed at the initial stage of the disease, once every 7 days, for a total of 2 times. The symptoms of Sclerotinia sclerotiorum first occur from the base of the leaf, and the spot is light brown, watery, rotten, and can be extended to the whole.

The method of changing Phalaenopsis pot
The substrate for planting Phalaenopsis requires good drainage and slightly water conservation, as well as ventilation and ventilation. Commonly used are tree fern root, water moss, bark, charcoal, coconut capsid and ceramsite and so on. No matter what kind of substrate you use, when the Phalaenopsis plant is too large and the air roots wind around each other, it is necessary to change the basin. The basin change should be carried out in the summer of the growing period. the method is to first pour out the plant, remove the old cultivation substrate, cut off the aging and decaying air roots, and then put a layer of charcoal on the bottom of the new basin, put in the plant, fill in the new substrate, and compact and drench.

Phalaenopsis changing pots
1. Selection of basin: generally choose plain fired pottery basin or plastic basin, porous basin is better, shallow basin is suitable for breathability, basin height is better than basin diameter. 2. Selection of culture medium: Phalaenopsis is a typical epiphytic orchid, its root system is well developed, and the cultivation substrate must have the characteristics of looseness, ventilation, good air permeability and rot resistance. According to the author's cultivation experience, pine needles, peanut shells and bark shreds should be selected as substrates for Phalaenopsis cultivation in the north. The basin must be changed every year. If the pot is not changed in time, the rot of the pot substrate will cause shrinkage and poor air permeability.

The material is made of water moss (suitable for medium and small seedlings), whole snake sawdust and snake sawdust plus water moss or half of snake sawdust and charcoal particles, and the effect is very good. Others such as vermiculite, cement charcoal soil, Alsophila spinulosa root, coconut shell grains can also be used as plant materials. two。 Watering: Phalaenopsis is native to primeval forests with high humidity. And there is no thick pseudo-corm to store nutrients and water. Therefore, Phalaenopsis should be cultivated and maintained in an environment with high ventilation and humidity. The optimum humidity during the day is
