Before your orchids bloom, choose an appropriate size stake and attach the plant with green floral tape. You can paint your stake green to match the plant.
Add a stake to the plant container that is the same size in height as the plant. Loosely tie the plant to the stake with string or other light material.
You want to carefully stake them with poles that match the foliage but be careful and wear gloves when staking. You should also wipe the stakes with bleach. Orchids are prone to disease.
