How to Rescue an Orchid That Is Too Dry and Not Growing Roots?

Many flower lovers have encountered this problem when growing Phalaenopsis orchids: the pot feels bone-dry, and when you dig in, the roots look wilted, with no new roots in sight. Does a Phalaenopsis being too dry really affect root growth? And if it happens, how do you rescue it?

Phalaenopsis is different from the common pothos and spider plant; its roots are aerial roots that like a humid yet airy environment. If the air humidity is too low and the potting medium is dry as a brick, the roots cannot absorb water and will enter a "dormant" state. Never mind growing new roots; even the old roots may gradually shrivel and die. Moreover, in too dry an environment, Phalaenopsis cannot even manage basic nutrient transport, and it has no energy left to grow roots or sprout.

So when you find your Phalaenopsis is too dry, how do you rescue it? Don't panic; treat it according to the situation. If you have just noticed the leaves are a bit wrinkled and the potting medium is completely dry, but the roots have not completely withered, this counts as "mild dehydration" and is relatively easy to rescue. First, immerse the pot in clean water, with the water level not above the rim of the pot, and let the potting medium slowly soak up water; just soak for 15 - 20 minutes. After taking it out, move it to a ventilated spot with indirect light so the excess water evaporates as soon as possible. At this point, absolutely do not put it in the sun; a dehydrated Phalaenopsis is too fragile, and one exposure to sun will surely give it "heatstroke."

If the dehydration is more severe, with leaves limp and roots already shriveled and gray, then you need to use the "bath method." Find a clean container, pour in room-temperature water, and you can add some diluted rooting powder or carbendazim to the water. Soak the whole Phalaenopsis in it, with the water level reaching half the height of the plant, and soak for 1 - 2 hours. This is like giving the Phalaenopsis a "hydration spa" the rooting powder can stimulate new root growth, and the carbendazim can also prevent root rot. After soaking, cut off the rotten and hollow roots, and repot with clean sphagnum moss or bark. Soak the sphagnum moss in advance and squeeze out the excess water, and also wet the bark, to create a humid environment for the roots.

The rescue is not the end of it; follow-up care must also keep up. For everyday watering, do not just water "when you remember to" you can poke the potting medium with your finger, and when the bottom 2 - 3 cm is dry, water thoroughly; or lift the pot, and when it is noticeably lighter, it is time to replenish water. When the air is dry, spray water around it every day, but do not spray directly on the leaves and flowers, to prevent crown rot. If you have the air conditioning or heating on at home, it is best to place a basin of water or a humidifier nearby, keeping the air humidity at around 50% - 70%

Growing Phalaenopsis requires more observation and more attention. As long as you master the correct rescue and care methods, even if a moment of negligence leaves it short of water, it can slowly recover, grow big white roots again, and bloom beautiful flowers.
