Repotting
Do I really need to repot my orchid? If you want it to re-bloom, then yes.
Orchids need fresh mix to stimulate new root and shoot development. Over time, bark begins to breakdown, clogging up the pore space, thus reducing the air to the roots. It also releases large quantities of nitrogen, weakening the root structure. A weak orchid is less likely to bloom.
Timing is Everything:
Your orchid needs to be repotted after the completion of the blooming cycle. We recommend that this is done annually to promote new roots and foliage growth.
Selecting the Correct Mix:
Gubler’s Orchid Grow products are ideal for all orchids, so the choice becomes, Moss, Fine or Coarse? It's best to repot in whatever medium the orchid is currently growing in. Match the plant tag to the grow medium, instructions are on the package. It's that easy.
Grow Moss and Fine Grade are ideal for Phalaenopsis.
Fine Grade also works well with Cymbidiums, Paphiopedliums, Oncidinnae and Terrestrial orchids and most intergeneric orchids. Any type of orchid seedling that is 3″ (7 oz) or smaller should be grown in Fine Mix. Look for the bag with the blue bar.
Coarse Grade is the right choice for Cattleya, Dendrobium, Vanda and Epiphytic orchids. These larger pieces of fir bark enable increased airflow to the roots thus strengthening their overall structure. This Coarse Grade can also be used as an accent in small garden beds. The bag with the pink bar is what you're looking for.
