I like the articleCultivation Trigonidium
The Trigonidium Is medium in size; in winter it assumes a orangeyellow colouring. These are evergreen plants, which means they keep their leaves year round. These plants have an erect, columnar development. The Trigonidium has a shrub- like development. Fertilize Trigonidium
We suggest fertilizing periodically, every 20-25 days, using a specific fertilizer for orchids, to add to the irrigating water. Let’s avoid using fertilizers during the flowering period and leaving the fertilizer in direct contact with the roots. Light Trigonidium
We advise cultivating the The Trigonidium in a covered place, in an apartment or green house, as they don't like temperatures below 15°C: during late Spring they can be moved outdoors. Locate this plant in a partially shady place, where it can take in the solar rays during the coolest hours of the day.Let's locate the plants so that they can enjoy a good diffused brightness, but someplace where they are not directly hit by solar rays. Water Trigonidium
Water sporadically, with 1-2 glasses of water , leaving the soil dry for a few days before watering again; when watering we suggest avoiding excesses, but to wet the substratum well. Let's act every 1-2 weeks . Watering by immersion is suggested for orchids: it consists in soaking the containers in water up to the edge, when the soil is moist let's take out the vases and let the excess water drain before putting them back in place. Pests Trigonidium
An insecticide treatment should be applied only if damaging insects have been seen on the plant; vaporizing the product we avoid spraying it on the flowers. Mold Trigonidium
Let’s prepare a soft and incoherent soil for these plants, which has an excellent drainage.
