Compost and drainage

Twinkle Oncidium needs sharp drainage, so this matters more in a pot than in the ground. Use a free-draining mix (add perlite, grit or bark to standard compost), always pick a container with drainage holes, and never let it stand in a saucer of water.

Watering twinkle oncidium in a pot

Containers dry far faster than open ground, so twinkle oncidium in a pot needs checking more often than the general guidance of "When the top of the mix begins to dry, about every 4-6 days" — especially in summer, wind, or a heated room. Check the top few centimetres with a finger rather than watering on a fixed day.

Potting on

Pot on when roots show through the drainage holes or growth slows noticeably — usually every 1-2 years for a plant this size. Move up one pot size only; jumping several sizes leaves wet compost the roots cannot reach, and that is what rots them.
