oncidium “sweet sugar” is a cultivar based on onc. “aloha iwanaga” und onc. varicosum. its flowering in yellow and the pseudobulbs can get more than 10 cm/3.94 inch tall.
oncidium “sweet sugar” does best if located bright with some morning and/or evening sun. light shade will be tolerated.
it can be grown at room temperature the year round with a winter minium of 14 °c/57 °f.
oncidium “sweet sugar” needs a special orchid mix (with fir bark and peat moss) and can’t be grown in a regular potting soil. repott every 2-3 years when the soil is going to break down and the orchid begins to outgrow the pot.
drench the soil well, water running out of the pot’s hole should be removed after a few minutes. wet legs can cause root rot. before watering next let it become moderately dry. if the pseudobulbs begin to shrink means that you have kept your orchid too dry.
a half diluted orchid fertilizer can be given monthly in spring/summer and every six to eight weeks in fall/winter (if placed at room temperature).
oncidium “sweet sugar” likes to be sprayed over every morning, so the water can evaporate throughout the day. with this extra humidity it can tolerate if the soil gets a bit drier for some times.
reblooming oncidium “sweet sugar”
the flower spike can be cutted after it has dried. the old growth will not bloom again. after blooming oncidium “sweet sugar” is producing new shoots. eight to twelfe months later they will show the pseudo-bulbs. now the orchid is ready for blooming again.
for producing its inflorescense a few weeks at approx. 16 °c/60 °f can have an positive impact. now it has to be kept a bit drier and must not be feeded until it’s showing the flower spike.
