How to manage the watering and fertilizing of Phalaenopsis orchids
Today, let's delve into the topic of managing the watering and fertilizing of Phalaenopsis orchids in the field of green plants and flowers. Next, the site editor will introduce the content to our netizens.
(1) Phalaenopsis orchids dislike waterlogging and prefer ventilation and dryness. Usually, if the pot is still very wet 5-6 hours after watering, it can cause root rot.
(2) Using moss as the potting medium, water can be given every few days; for fern roots, vermiculite, wood blocks, and bark blocks with poor water retention, water can be given once a day. Wait until the surface of the medium is dry and the pot surface is white before watering.
(3) When the temperature is below 15°C, watering should be strictly controlled. If the roots feel slightly moist to the touch, there is no need to water. In winter, as long as the room temperature is not too low, water promptly when the surface of the medium turns white and dries.
(4) The ambient humidity should be high. The average annual relative humidity should be maintained at 70% to 80%; during dry seasons, water the ground and other areas several times a day or spray a small amount of water on the leaves; when the temperature is below 18°C, reduce the air humidity and avoid spraying water on the leaves at night.
(5) Phalaenopsis orchids require a slightly higher amount of fertilizer than general orchids, but it should be applied in small, frequent doses. Apply a small amount of fertilizer in spring, stop fertilizing during the blooming period; after the blooming period, apply liquid fertilizer once a week (1000-2000 times dilution); after new leaves appear, apply a small amount of solid organic fertilizer to the pot surface; after repotting, wait a month before applying some diluted liquid fertilizer; during summer, apply liquid fertilizer once a week, stop fertilizing during hot and humid weather; stop fertilizing from the end of October; do not fertilize in winter. Apply nitrogen-containing fertilizers during the growing period; apply fertilizers with a high potassium-phosphorus ratio during the bud formation and blooming periods.
