There are over 30,000 species of orchids and 200,000 orchid hybrids. While these plants are often viewed as indoor plants, orchid bulbs that are made available at most garden centers and plant nurseries can grow well outdoors. The goal of growing healthy orchids is to choose a species that will be viable for your growing region. You can determine if a species is adaptable for your area by reviewing the planting zone information that is made available on the packaging of the orchid bulbs.
Choose a planting site that receives dappled to partial shade. If you live in a growing region that is very hot and dry, you will need to choose a location that receives a bit more shade than sun. Plan to plant your orchid bulbs in the spring when the threat of frost has passed in your growing region.
Dig holes with your fingers or a small trowel. The holes should be 3 to 4 inches deep and 2 to 3 inches wide. Space the holes 12 inches apart.
Place a bulb into each hole and lightly pack the soil around the bulbs. Gently tap down on the soil to ensure that no air pockets remain around the bulb.
Water thoroughly and plan to water whenever the soil dries out. When the bulbs begin to sprout and grow, mist them every day or two with a water bottle.
Stake heavy orchids that have trouble standing. This will keep your orchids from breaking if they should fall over. Use a small plastic garden stake and twine. Secure the plants loosely with the twine to allow the stalks to have growing room.
Things You Will Need
- Plastic garden stakes
- Fertilize every two months during the growing season with a liquid plant fertilizer that is at half strength.
- Because there are so many species of orchids, you should follow the growing tips and guidelines for the specific species of orchid bulbs that you are planting.
