How often should you water a Phalaenopsis in autumn? Master the frequency and techniques to grow orchids in autumn without root rot!
Many people who grow Phalaenopsis orchids start worrying in autumn: as temperatures gradually drop, they fear root rot if they water too much, yet fear dryness if they water too little. So how often should you water? In fact, there is an art to watering Phalaenopsis in autumn: you can't blindly fix a number of days, and you also need to adjust based on its growth state. Below, we will explain the frequency, timing and precautions for autumn watering clearly, to help you keep your Phalaenopsis lush and thriving.

There is no absolutely uniform standard for how often to water Phalaenopsis in autumn, but most of the timewatering once every 7-10days
is enough.

But this is only a reference; the key is to look at the environment--if the humidity at home is high (for example, autumn in the south), the potting medium dries slowly, so delay it by2-3days; if the autumn in the north is dry and windy, the potting medium dries quickly, so shorten the interval appropriately. Do not stubbornly stick to the"7-10days"rule; flexible adjustment is the key.

Now let's talk about watering timing. In autumn, many Phalaenopsis orchids enter the spike-growing stage. At this time, lack of water can easily affect the growth of the flower spike, but you also should not water too frequently.

It is best to wait until the potting medium is about 80% dry before watering: for example, use your hand to push aside the surface sphagnum moss or bark. If the potting medium below feels dry to the touch and has no moisture, or if you lift the pot and it feels noticeably lighter, then you can water. Never wait until the potting medium is completely dry and the roots are wrinkled before watering, as that can easily damage the roots and affect subsequent blooming.

There are also a few precautions to remember: in autumn the air is dry. If the humidity at home is below50%, watering alone is not enough. You can use a spray bottle every morning and evening to spray a little water around the leaves (do not spray into the leaf crown or onto the flower spike, to avoid crown rot), increasing air humidity. This not only keeps the leaves green but also helps prevent pests such as spider mites that like dry environments.

In addition, for watering it is best to use tap water that has been left standing for1-2days, or cooled boiled water. The water temperature should not be too cold; it is best if it is similar to room temperature, to avoid cold water shocking the roots. When watering, slowly pour along the edge of the pot so the potting medium absorbs water thoroughly. Do not directly flush the roots, to reduce the risk of root rot.
