Trim spent flower stalks from the plant. Remove the orchid from its pot. Wash all potting media away from roots with water.
Inspect the roots and identify healthy plump, white roots. Cut away damaged and diseased roots that are brown and mushy.
Choose a pot sized to hold the remaining root mass and potting medium without crowding.
Place the roots and the medium in the pot. Do not pack the potting medium around the roots; they require air circulation.
Thoroughly soak the potted plant and allow to drain.
Place the pot on the gravel-filled tray. Fill the tray with enough water to come up to below the bottom of the pot.
Place the pot in a sunny east or south exposure.
Monitor room temperature near the window. Maintain ideal temperatures between 60 and 85 degrees F.
Fertilize twice each month with a balanced 1:1:1 fertilizer during spring and summer. Use a 1:3:1 fertilizer in fall when flower buds are setting. Reduce fertilizer by one-half during the dormant winter period.
