For Phalaenopsis grown in bark, is thick or thin bark better, and does it need to be soaked in advance?

Phalaenopsis is an epiphytic plant that likes a loose, breathable growing medium, and bark is a common choice. Some growers ask: for growing Phalaenopsis, is thick bark better or thin bark better? Does the bark really need to be soaked in advance before use? When it comes to choosing bark thickness, each has pros and cons, and the decision should be based on actual needs; pre-treatment before use also affects the plant's growth condition.

What are the differences between thick bark and thin bark? Thick bark is the big-chunk kind, hard to the touch; oak bark and pine bark both come in thick forms. Thin bark is relatively thinner, more broken up, and easier to pinch flat. Many people agonize over which to choose, but in fact each has its own advantages and disadvantages.

The advantages of thick bark are obvious! First, its water retention is especially strong; after one watering, the moisture can stay inside for a while. And its breathability is also good; the large chunks leave big gaps between them, so Phalaenopsis roots are not easily suffocated. In addition, thick bark lasts a long time and does not rot easily, so you do not need to change the medium for a year and a half. But it also has drawbacks: at first it does not absorb water easily, and if you do not pre-treat it, the water just runs off to the side when you water. Thin bark absorbs water much better; after watering it becomes thoroughly wet quickly, and for beginners it is easier to judge when to water. But its water retention is poor, it dries fast, and it rots before long, so it needs frequent repotting, which is rather troublesome.

So which bark is actually better to choose? It depends on your care habits and environment. If you are usually busy and cannot look after the Phalaenopsis every day, or the air at home is fairly dry, then choose thick bark; watering once every half a month is no problem. If you have plenty of time, like fussing over plants every day, and the humidity at home is suitable, thin bark is very suitable, letting you observe the Phalaenopsis's water needs at any time. Of course, there is also a lazy shortcut: mix thick bark and thin bark together to make up for each other's shortcomings; the effect is great too!

Now let's talk about whether bark should be soaked in advance before growing Phalaenopsis. My answer is: it must be soaked! If you do not soak it, the bark is like a dry sponge and simply cannot hold water when you water; the water runs straight out of the bottom of the pot, and the Phalaenopsis roots still cannot drink. The soaking method is simple: find a large basin, put the bark in, fill it with water, and let the bark be completely submerged. Thick bark is more stubborn and needs to soak for 24 hours or more to let it drink its fill thoroughly. Thin bark needs only 8 - 12 hours. After soaking, fish the bark out, drain off the water, and it is ready for planting Phalaenopsis.

Besides soaking, it is best to disinfect the bark before use. You can soak it in a carbendazim solution, or boil it in a pot, to kill the pathogens and insect eggs inside, so the Phalaenopsis roots are less likely to get diseased.

Actually, whether you use thick bark or thin bark, the key is to figure out the Phalaenopsis's temperament. Observe its condition more: if the leaves are soft, it is short of water; if the leaves are firm, there is no rush to water. Put in a bit more care, and the Phalaenopsis will naturally repay you with beautiful flowers.
