What to Do About Root Rot in Phalaenopsis Orchids? Cause Analysis and Treatment Methods
The impression of Phalaenopsis orchids may come from elementary school, when I knew nothing and thought the flowers that bloomed were really butterflies that could dance, beautiful and colorful, which shows just how lifelike the flower shape of the Phalaenopsis is. As one of the tropical orchids, the Phalaenopsis is deeply loved by flower enthusiasts for its unique shape and rich colors, but during the care process it very easily develops root rot, so what should you do? How can you grow it so it thrives?
I. What to do about root rot in Phalaenopsis orchids?
1. Causes of root rot in Phalaenopsis orchids
Root rot in Phalaenopsis orchids can be caused by many reasons, such as excessive water accumulation, over-fertilizing, poorly aerated potting soil, high air humidity, and pest and disease infestation, all of which can lead to root rot.
2. Solutions for root rot in Phalaenopsis orchids
(1) Dig out the root system of the Phalaenopsis
If the Phalaenopsis shows yellowing leaves, leaf drop, crown rot and other conditions, then you need to check its root system. First dig out the whole Phalaenopsis plant, remembering to dig it out with the soil, then clean off the soil attached to it.
(2) Wash and cut off the rotten roots of the Phalaenopsis
After washing the root system of the Phalaenopsis clean, cut off its rotten roots. Note that the cutting tools must be sterilized, otherwise they will spread pathogens.
(3) Treating the wounds
Cutting off the rotten roots will leave wounds, and if they are not disinfected, the plant will not grow well either. So you can soak the roots in a professional solution for a while, then let them dry. After drying, you can sprinkle some plant ash on them before repotting.
(4) Potting details
Potting is the most critical detail, and the potting soil must also be disinfected to avoid carrying the original virus. Here you can pour boiling water through it, then let the potting soil dry, and only replant the Phalaenopsis after it has cooled. At this time you must pay attention to the humidity and temperature of care, and quietly wait for it to recover to its original state. If the root system grows new roots again, that means the problem has been handled well.
Of course, if you find it too troublesome, you can also just change the pot and the soil, so that you do not need to treat the soil with boiling water.
II. How to grow Phalaenopsis orchids well?
1. Choose a suitable growing medium or soil for the Phalaenopsis
Generally the common ones are water culture and soil culture. Water culture requires water moss or moss-type media, while for soil the requirements are not high, and loose, breathable soil is enough.
2. Master the right growing temperature for the Phalaenopsis
Generally speaking, if you want good blooming and emerald-green leaves, you must ensure the growing temperature. 15-30°C is relatively reasonable; if it is too high or too low, it will grow slowly, and the leaves will turn yellow or drop.
The cultivation medium for Phalaenopsis is mainly moss and water moss. Generally, soil cultivation requires somewhat loose soil.
3. Light for the Phalaenopsis must be appropriate
For a shade-loving plant, light must be well controlled for it to grow well. Generally, diffused-light care is enough, but in the early flowering stage and during the flowering period, you must ensure sufficient light, guaranteeing 3-4 hours of light per day, but avoid direct sunlight, especially in summer, when shading is needed.
4. Phalaenopsis orchids need sufficient water
Because the leaves of the Phalaenopsis do not easily store water, but during the vigorous growth period it needs a great deal of water, so you must water regularly. In winter, water less to avoid water accumulation and root rot. In summer, if the potting soil is on the dry side, you can appropriately increase the amount or frequency; if it is slightly moist, then reduce it. In summer, watering is generally done before 9 a.m. or after 5 p.m., and the area around the leaves should also be sprayed appropriately to lower the temperature. In spring and autumn, water once every 1-2 days, generally in the afternoon.
5. Fertilizing tips for Phalaenopsis orchids
Fertilize Phalaenopsis sparingly in winter, with low concentration; during the growth period you can choose a professional nutrient solution, fertilizing frequently and lightly.
6. Phalaenopsis orchids should be placed in a ventilated environment
Without ventilation, Phalaenopsis is very prone to pest infestation, with wilted leaves, pale leaf color, or yellowing and leaf drop.
In addition, appropriate pruning is also a way to ensure the overall growth and beautiful flower shape, so as to avoid too many side branches competing for water and nutrients, which would leave the whole plant malnourished, weak in growth, and with small flowers or no flowers.
