Although Phalaenopsis is beautiful, it is considered by some people who are not flower enthusiasts to be the kind of flower that is most likely to die easily. This is because of its delicate appearance like a work of art, which gives the illusion that it is difficult to grow. In fact, different people have different opinions on this. In the world of flowers, there is no such thing as a plant that is easy or difficult to grow; it mainly depends on personal patience and perseverance. So, what are the most common problems encountered when growing Phalaenopsis?
Types of Pests
Thrips: The most common pest on Phalaenopsis is thrips. These insects not only damage the leaves but also the flowers. When thrips run rampant, the leaves of Phalaenopsis will turn black and wrinkled, and there will be many spots on the flowers, which will affect the overall ornamental value of the orchid. It is best to spray with Rui Li in advance for prevention.
Scale Insects: Scale insects, after emerging, usually pierce their sharp mouths into the leaves of Phalaenopsis and suck out the sap, causing the leaves to turn yellow for no apparent reason. At this time, check the back of the leaves to see if there are any scale insects hiding in the leaf axils.
Spider Mites: Spider mites also like to live on Phalaenopsis. After they appear, dense small white dots will appear on the leaves, which may look like some variegated leaf varieties, but this is not a good thing. Spider mites can be seen on the back of the leaves by using a magnifying glass. At this time, to treat the problem, immediately spray water on the plant to increase the humidity and then use insecticides.
Types of Diseases
Stem Rot: First of all, stem rot is the most serious disease that affects Phalaenopsis. After the onset of this disease, the base of the stem begins to rot and it is very difficult to cure. During daily observation, if the middle leaves turn yellow, it may be a precursor of stem rot. You should quickly place the orchid in a ventilated place and pay attention to check if the base of the stem is rotting. If it is really rotting, clean up the rotten part and apply some fungicide.
Soft Rot: Soft rot is another common and relatively easy-to-solve disease. It is a bacterial disease, and the affected area will rot and give off a fishy smell. (Kasugamycin) can be used to prevent and control it.
Anthracnose: For anthracnose, dark brown spots will appear in the middle of the leaves, or the edges will be grayish-brown, and some may have concentric rings. In severe cases, the leaves will have holes. Secondly, fungal infections can cause spots on the leaves. If the leaves are seriously damaged, cut them off directly and then quickly spray with a fungicide.
Rotavirus: This is a viral disease. After the onset of the disease, immediately cut off the affected leaves and then treat with oligochitosan.
