REBLOOMING:
REBLOOMING YOUR ORCHIDS
Each genus of orchid has different requirements for reblooming. Most commercial varieties are very
simple to rebloom. Phalaenopsis, Zygopetalum and Odontoglossum require only slight changes in
temperature to initiate blooming. Others, such as Oncidium and Dendrobium, bloom on mature new
growth and require a change of fertilizer to a phosphorus-rich, blossom-booster formula, such as 20-20-
20.
