Care Notes

These orchids live on the forest floor and keep tubers to store energy and nutrients during dormancy and poor weather. They are generally quite forgiving and usually thrive on neglect, as long as it's the type of neglect where they are forgotten to be watered or fertilised, as overwatering can cause rot, and excessive fertilisers can affect the fine root system.

They are quite forgiving when it comes to light and environmental conditions, as long as they have enough moisture in the soil to keep going. Damage to leaves from overexposure to light or dry conditions has no long term implications as the plant will withdraw back to the tuber and be replaced with a new plant in the next season. Just be sure not to overwater damaged plants as they will rot.

They will enter a dormancy phase where leaves are shedded the plant withdraws back to the ground. During dormancy tubers can be removed from the soil, kept in a dry cool place if required, replanting when new roots appear. However, most plants will do better if not disturbed, and replanting late can set back the plant and reduce the likelihood of flowering in the following year.

In many areas these can be grown in the garden, needing little maintenance. 

Climate

Grows at low to high elevations.

Fertiliser

These plants do well with slow release fertiliser at the rate of 2-3 pellets per cup (250ml) of media. Additional fertiliser during the growth period may be beneficial, but not necessary.

Potting

These plants can be sensitive to repotting though should not require repotting regularly. Repotting should be done when the mix has broken down to the point that it doesn't absorb water or holds onto water for far too long, usually the plant shows a decline in growth as well.

The mix should be free draining, with a blend of 30% inorganic ingredients such as coarse sand, gravel or perlite, mixed in with about 70% organic ingredients such as peat, leaf litter or decomposed bark. Avoid commercial potting mixes as they can vary wildly and may contain "wetting agents" that can hold onto water for loo long, causing rotting and stunted growth.
