You are not likely to encounter Oncidopsis (Burrageara) Nelly Isler, a Cambria-type orchid, on your holiday to the tropics. It is namely a hybrid, a cross between various species. This orchid’s creator named it after his wife, Nelly Isler. When Nelly Isler is placed in a cool location, the flowers become dark red and the plant releases a delicious sweet scent. The plant can even produce more than one stem in the right living conditions.
Light: In a bright spot, but no direct sunlight.
Temperature: Ensure a cool and airy environment. Standing outside during the summer this plant should be sheltered.
Water: This orchid should not be overwatered. It is sufficient to water it once every seven to nine days. Water Nelly Isler only once its soil is almost dry. This can easily be determined by means of a skewer. Stick the skewer in the soil and retrieve it occasionally. Nelly Isler requires water if the skewer is dry.
Spraying flower buds: The humidity in a home can be low during the winter and summer months. Spray the smallest buds daily to prevent them from drying out and not flowering.
Fertiliser: Twice per month, feed Nelly Isler our special orchid fertiliser ‘Groei en bloei’.
Dosage: one level teaspoon per one litre of water. In February, May, and September, sprinkle one level teaspoon of ‘Grondverbeteraar’ (soil improver) once over the potting mix. The orchid does not require fertiliser from November up to and including January. Both products are sold in our shop.
Soil: It is important to replant Nelly Isler once every three to four years in orchid potting mix. For oncidium, the Orchideeën Hoeve has put together a well-aerated mix of bark, coco, and peat. This mix is available at our shop. Please do this if the orchid has finished flowering (preferably in springtime).
After flowering: Please do cut off the stem at the bottom if it is past flowering. The orchid will generate another stem from a new shoot. This will take approximately eight to twelve months.
