The simplest three-step treatment for yellow leaves and root rot in Phalaenopsis orchids: what to do when the medium is too wet?

Friends who have bought Phalaenopsis orchids surely all want the plant to produce a lively mass of blooms, so they can show off a bit when family and friends come over. However, in daily care, the most troubling thing is that as you grow it, the flowers end up crooked, or even yellow leaves appear, blooms wither before opening, roots rot, and so on.

Looking at common problems in orchid growing, yellow leaves and root rot are the most common issues, because most people mistakenly care for orchids like ordinary flowers. However, its roots are actually especially sensitive, and even a slight change in temperature, climate or environment will affect its growth. Among these, the most common source is the "sphagnum moss" medium. Next, let's talk about the usual condition of Phalaenopsis orchids once the medium has problems, and how to handle it.

First, when a Phalaenopsis orchid has yellow leaves or root rot, this is mostly caused by improper watering. To handle it, first cut off the moldy leaves, and apply a little carbendazim to the wounds to disinfect them. If the roots have already turned black, you have to take it out of the pot, trim off the rotten roots, put it in a ventilated place to dry, then replace it with new growing medium and replant. After replanting, the orchid's watering must be controlled for the next half month; it is best to just mist the leaf surfaces a little. Once you see new roots growing, you can go back to normal care and management.

In addition, if the roots simply are not damaged and it is only that the sphagnum moss is too wet, you can let the roots be temporarily exposed and place it in a ventilated spot to speed up water evaporation, then return to normal care once it has dried out somewhat.

Finally, let's talk about a little trick to make a Phalaenopsis orchid bloom again. After the flowers fade, cut the flower stem back at the 3rd node, then give it some general-purpose fertilizer so the plant regains its strength. In autumn, if you want it to bloom at Spring Festival, you can regulate the flowering period by shading: give it 14 hours a day in a dark environment, which promotes flower bud differentiation and smooth blooming. Master these methods for dealing with common problems and encouraging reblooming, and your Phalaenopsis orchid can bloom every year with even greater ornamental value. Give it a try!
