Plant of the Month - September, 2017

Oncidium (Colmonara) Masai Red

The Oncidium (Colmonara) Masai Red that Synea Tan shared with us walked away with that honor this month. The healthy looking plant had a tall inflorescence with lots of red flowers. Synea grows it out of doors on a veranda on the north side of her house for the summer and indoors under LED light tubes in the winter. She grows it in a plastic pot into which she burned lots of extra air holes. Her mix consists of Styrofoam beads and cut pieces of New Zealand sphagnum moss. She waters it twice a week with a weak solution of MSU fertilizer in rainwater (1/4 tsp/ gallon of water). She occasionally uses Miracle Grow instead of MSU. Once a month all her plants get plain rain water. But while it is outside she waters it more frequently. She repots it once per year.
Synea also had a beautifully flowered Cycnodes Wine Delight AM/AOS with red flowers arranged around the rim of the pot. This plant is potted in clay pellets mixed with Styrofoam pellets and cut up NZ sphagnum moss. Strangely, she keeps it wet all year which probably means she never lets the temperature drop below 65F and thus avoids the onset of several months of dry rest.
Synea also mentioned that she uses a mix of Orchidata bark, Perlite and Clay pellets for her Paphiopedilum rothschildiannum with good results.
Beautifully done Synea!
