Indoor orchids fall in intermediate, warm or cool temperature categories. The temperature range of the orchid's location is collected using a high-low thermometer. Temperature results help homeowners select the right orchid. While some orchids prefer medium-high lighting, others do well in medium-low or low light. Medium-high light orchids require brightly lit conditions, but not direct sunlight. Medium-low lighting orchids thrive best when placed near west- or east-facing windows. Low light orchids grow best in locations with limited exposure to light like under an overhang or a tree.

Grouping the plants or placing them on a dry well will help increase the humidity levels near orchids. Dry wells are created using pebbles placed on a tray with water reaching the top of the pebbles. The orchid plant is then placed on top of the pebbles.

Bark mix is used in place of soil in orchid pots. Clay pots should be soaked for 15 minutes in a bowl of water to give enough time for water to penetrate the pot’s walls. The bark mix absorbs water from the pot to the plant.

Half-strength fertilizer is applied to orchids during the production of new leaves. However, delivering water without fertilizer at least once a month helps flush out excess fertilizer salts from the bark mix and prevent fertilizer burns on the roots.
