Why the Leaves of a Newly Bought Phalaenopsis Wilt and Whether You Can Mist It

Many friends excitedly carry a Phalaenopsis (moth orchid) home, only to find a few days later that the leaves are drooping and the flower buds are turning yellow, and they panic instantly. Actually, if a Phalaenopsis wilts as soon as it arrives home, eight times out of ten it is these few reasons causing the trouble!

First, it may be "protesting the move." The Phalaenopsis we buy from flower shops or online originally lived in greenhouses, where the temperature, humidity and light were all VIP treatment. Suddenly being brought into your home, with the environment changing abruptly, the temperature fluctuating, and the air being dry, it is bound to suffer from not adapting.

Second, watering is also easy to get wrong. Some friends think that if the flower is wilting it must be thirsty, so they water it heavily, and as a result the roots are smothered in soggy potting medium and rot outright! Phalaenopsis is an epiphytic orchid with aerial roots, liking alternating dry and wet conditions, and it fears waterlogging most of all. There is also another situation: the seller may have watered it too much before shipping to make the Phalaenopsis look fresh and dewy, so by the time it reaches you the root system is already swollen from soaking, and its condition naturally cannot be good.

So can you mist water as first aid when the leaves wilt? The answer is: it depends on the situation! If it is only that the air is too dry and the leaves are a bit wrinkled, you can use a spray bottle filled with room-temperature purified water, hold it about 20 cm from the leaves, and mist gently to replenish the moisture for it. But if the leaves have already gone soft and drooping, or you find signs of root rot, then absolutely do not mist! At this point misting will only make the pathogens more active and speed up root rot.

The correct approach is to first put the Phalaenopsis in a ventilated spot with bright, indirect light to recover, for example by a living room window, avoiding direct sunlight. Observe it for a few days; if the surface of the potting medium is dry, soak the whole pot in water for 10 minutes so the medium slowly absorbs enough water, then lift it out and let it drain. If you find the roots are black and mushy, immediately take it out of the pot, cut off the rotten roots, soak it in carbendazim, and repot it with fresh sphagnum moss.

If you want your Phalaenopsis to come back to full health, there are also little tricks for daily care. For example, do not put it next to a heater in winter, and do not let an air conditioner blow on it in summer; every half month give it some orchid-specific fertilizer, diluted into a weak nutrient solution and watered on and usually open the windows more for ventilation so it can breathe fresh air. As long as you master these key points, your Phalaenopsis can bloom every year too.
