Care Methods and Watering Tips for Phalaenopsis Before Blooming

Always envious of other people's Phalaenopsis orchids blooming into a cascade of flowers? The truth is, the care before blooming is the key! Master the "golden ratio"for temperature, light, water and fertilizer, and even beginners can grow buds all over the branches.

Temperature

Phalaenopsis orchids are extremely sensitive to temperature, and if you want to force them into bloom you must control the temperature strictly:

Daytime 26-28°C: warm but not hot, like the temperature of a sunroom in spring, just enough to activate its growth power.

Nighttime 16-18°C: it must not drop below 16°C! Maintaining a temperature difference of 8-10°Cis the key, the equivalent of giving it the instruction "time to grow buds"

Winter warmth: if the room temperature is low, put on a transparent insulation cover (leave ventilation holes), or place it 1m away from a heater, making sure the ambient temperature does not drop below 18°C

Light

Duration: 4-6hours of indirect light per day; an east-facing windowsill before 9in the morning is perfect, with soft, non-harsh light.

Intensity: 25000-30000Lux (simply put, bright enough to read a newspaper by the window without straining); use a 30%shade-rate shade net to filter strong light and prevent the leaves from getting scorched spots.

Things to avoid: absolutely avoid west-facing exposure and midday sun; once the leaves are sunburned, photosynthesis weakens, and getting it to bloom becomes doubly difficult!

Water and Fertilizer

Watering: wait until the surface of the sphagnum moss turns white, the bark feels dry and hard to the touch, or the roots are slightly wilted, then you can soak the pot --place the pot in shallow water and soak for 10minutes, letting the substrate slowly absorb its fill of water and avoiding water flowing into the crown of the plant and rotting it from a direct pour; in spring and autumn water once every 3-5days, and in winter once every 10-15days, watering again only when the substrate feels dry by hand; better dry than wet!

Fertilizing: when you see small bumps in the leaf axils (a sign of flower buds), you can start feeding it ~ Use monopotassium phosphate 1000times solution (1g of fertilizer mixed into 1liter of water), once every 10days; either drenching the roots or spraying the undersides of the leaves works, and absorption is faster; once the flower stalk grows to about 15cm

Substrate

Substrate recipe: sphagnum moss +pine bark=3:2 sphagnum moss holds water and bark provides aeration, and after mixing, a handful squeezed into a ball should crumble apart, neither compacted nor waterlogged; repot once every spring, and when repotting cut off rotten roots and hollow roots, apply carbendazim to the wounds to disinfect, let them dry for 1day, and then pot them up again.

Getting humidity right: air humidity of 60-80% is most comfortable; too dry will make the leaves wrinkle and the buds shrivel.

When it is dry, place a shallow tray of water next to the pot (rest it on a brick, do not let the pot sit in the water), or run a humidifier, and mist the surrounding air 1-2times a day; never mist the buds and leaves directly, or they will rot.

Grown this way, in about 1-2months you will see the flower stalk emerge and slowly grow into a "flower spike"covered in buds ~ after it blooms, move it to a slightly cooler spot (around 20°C), and the flowering period can last as long as 2-3months!
