After the flowers drop from the orchid you have three choices: leave the flower spike (or stem) intact, cut it back to a node, or remove it entirely. Remove the flower spike entirely by clipping it off at the base of the plant. This is definitely the route to take if the existing stem starts to turn brown or yellow.
Orchids grow back not just once but for a lifetime as long as you provide them with proper plant care. They can rebloom on the same old flower spike as long as it is still green. You can also decide to cut the old bare flower spike back to a node to promote bushy and lush foliage.
This dormancy stage usually lasts about six to nine months. After that, your orchid will have the energy to rebloom again. However, sometimes orchids need help with this process and require even more attention than they did before. With the right amount of tender love and care, you can get your orchid to rebloom.
If you find that your orchid has bad roots, snip them off with a sterilized cutting tool and then repot it. On the other hand, if the part of the orchid that connects the leaves and the roots is mushy, it is time to toss the plant.
Your orchid has tightly tangled roots.
This is a surefire sign your orchid needs to be repotted. Give plants breathing room by placing it in a larger pot every year or two with fresh potting soil.
Trim 1 inch above that node, or bump, on the orchid spike. For unhealthy, brown spikes: Cut all the way back to the base of the plant. For double-spike orchids: Cut one spike at the base of the plant. Cut the other spike 1 inch above the node under the lowest flower bloom.
Let's talk about the Phalaenopsis orchid or moth orchid, the one you likely got from the grocery store. This is the only orchid that will rebloom on the same stalk. All other orchids will bloom again, but not from the same stalk. All other orchids can be trimmed at the base of the flower stalk.
Of all of the more commonly available orchids, only Phalaenopsis (the moth orchid) will re-bloom from its old spike. Phalaenopsis will generally re-bloom given a little extra care.
How long does it take a new orchid spike to grow? If you notice a spike forming, be patient; this fixture on your orchid can take around three months to grow. For healthy spikes, you'll want to have a healthy orchid in the first place.

New orchid spikes
Orchid flower spikes are usually greener than roots and have a flatter, mitten-shaped tip. While growing, spikes remain green along their full length. Orchid spikes usually emerge from between the plant's leaves, not from the plant's center.
