How to Repot Phalaenopsis With Spikes

A “spike” growing out of an orchid is the stem from which the orchid buds emerge. Of course, the best time to repot the phalaenopsis orchid is after it blooms, when the flower is gone and the spike has done its duty and turned brown. Sometimes, though, the plant requires repotting while in spike and it may be successfully done, with care. If there are buds on the spike, the chances of success dwindle. If the spike holds flowers, it's best to wait until after the flowers die to repot the phalaenopsis.

Instructions

    • 1

      Remove the phalaenopsis from its pot and use your fingers to gently brush the old planting medium from the roots. If you are planting into the same size pot, don't disturb the planting medium around the roots, but plant the entire bundle.

      Inspect the roots to ensure they are growing strong and not stressed. They should appear firm and white. If they are sparse, or the majority of them are discolored, the experts at Orchid Web suggest removing the spike so the orchid can put its energy toward root recovery. Use a pair of sterilized scissors or snips to remove the spike. Otherwise, disturb the roots as little as possible.

      Place a mound of fir bark – sometimes sold as “orchid bark” -- on the bottom of the new pot and place the orchid's roots on top, spreading them so that they dangle evenly over the mound. If they bend at the bottom, make the mound taller. They should just brush the bottom of the pot.

      Fill the pot with the bark, pressing gently on it as you add it to the pot. Stop filling when you get to the crown, as it should be even with, or just slightly below, the surface of the medium.

      Water the phalaenopsis until the bark is wet.
