What kind of bark should be used to grow Phalaenopsis orchids, and should they be kept constantly moist?

When caring for Phalaenopsis orchids, choosing the right growing medium is crucial, and bark, as a material with good breathability and moderate water retention, has become the first choice for many orchid growers. So which kind of bark is actually suitable for growing Phalaenopsis orchids? And do they need to be kept constantly moist?

Phalaenopsis is not like the pothos or spider plants we usually grow. It is an epiphytic plant, and its roots like to breathe, so it needs a loose, breathable growing medium. The most commonly used is pine bark, especially well-rotted pine bark. It is not only light and breathable, but also slowly releases nutrients as it decomposes, making it simply the dream growing medium for Phalaenopsis.

Besides pine bark, willow bark is also very good. Willow bark contains salicylic acid, which can promote root growth, strengthen the resistance of Phalaenopsis, and reduce the risk of root rot. If you cannot find these two kinds of bark, oak bark and fir bark can also work in a pinch, but remember they must be thoroughly rotted and disinfected. Soak the bark in water for a few days, then soak it in a carbendazim solution for half an hour to sterilise it, and then sun-dry it before using it with peace of mind.

Many people think that when growing Phalaenopsis in bark, the bark must be kept constantly wet, but this is actually a big misconception! Bark does not hold water as strongly as soil, but it also should not be kept in a constantly moist state. Although the roots of Phalaenopsis like a moist environment, if the bark stays wet for a long time, the roots can easily become oxygen-deprived, and eventually root rot and yellow leaves follow, leaving the whole plant drooping and listless.

So how exactly should you water? It is very simple. Before each watering, first use your hand to push aside the bark on the surface of the pot. If the bark feels noticeably lighter, the surface looks whitish, and the bark in the pot does not feel sticky to the touch, it means it is time to water. When watering, do not pour a little at a time. Water thoroughly directly, letting the water flow out from the bottom of the pot, washing away dirt and excess salts in the bark.

There is also a little trick: you can place a few pieces of expanded clay pebbles at the bottom of the flower pot. This can strengthen drainage and reduce the chance of root rot. If the air in your home is especially dry, in addition to normal watering, you can also spray some water mist around it to increase air humidity, but do not spray directly on the flowers and leaves, as this can easily cause leaf and flower rot.

Overall, choose the right bark and water correctly, and your Phalaenopsis will grow lush and produce a big beautiful spray of flowers.
