Will My Orchid Grow Flowers Again

You got a moth orchid as a holiday gift. Or as a birthday present. Maybe it came from your grandmother, who likewise informed you that the plant'due south horticultural proper noun is Phalaenopsis and that there are dozens of species. But this is non what concerns you: the problem is the flowers have shriveled, leaving behind a blank spike and a couple of waxy green leaves in a pot. Yous wonder, "When my orchid bloom over again?"

Mary Gerritsen understands your pain. Orchid whisperer Gerritsen coaxes hers to blossom over again every year—and shares her top plant care tips here.

The author of A Bay Surface area Guide to Orchids and their Culture has been growing orchids since the 1970s and says: "Most of the indoor orchids I take are ones someone got as gift and the blossom fell off then they said, 'Here,' and gave it to me."

Higher up: "About Phalaenopsis are shipped here from Taiwan, flattened in a container ship, smushed in Sphagnum moss," says Gerritsen. "When they become here, to go them to blossom they are grown in special circumstances involving calorie-free and temperature." Your task: replicate those circumstances at home.

What should I exercise when my orchid stops blooming?

The goal is to become your moth orchid to flower at to the lowest degree once a yr, for several months. (Some of Gerritsen'south will flower for viii to 10 months.)

First, cutting off the one-time flower stem at the base of the plant. Then put your moth orchid in a room in your business firm that simulates the weather that will cause it to flower once more. For starters, it will need a month'southward worth of  daily temperature drops of at least 10 degrees from day to nighttime.

"In your business firm, y'all tend not to have big drops; the temperature tends to be set to a steady 68 degrees," says Mary. So put your orchid in a room that gets a petty cold by the window—and put your orchid in the window. When the sun goes down, the estrus volition drop and the common cold will stimulate information technology to re-bloom.

Tip: "My room has a window that faces southward, has no heat vent, and basically has glass on two sides and a skylight, so it gets a temperature spike during the 24-hour interval," Gerritsen says.

When should I re-pot my orchid?

"Often the ones from the florist have damaged roots," says Gerritsen. "Make sure information technology'south not done up as a throwaway, stuffed in a pot with a bunch of pebbles, reindeer moss, and no drainage."

Tip: Re-pot, after an orchid stops blooming. Take it gently from its pot, shake off the old bawl, and cutting off whatsoever dead roots with a sterile razor blade or scissors. "Don't make the error of putting into a bigger pot, because orchids don't like that," says Gerritsen. "They like to accept their roots crowded in a minor space." So pot information technology into a same-size pot, property its leaves so the roots dangle into the pot. Add bark and gently mix the pieces around its roots to hold them snugly.

Gerritsen recommends a potting medium of Douglas fir bark to aid drainage and air circulation. A 1-gallon handbag of Douglas Fir Bark For Orchids is $23.99 from Amazon.

How much sun does a moth orchid need?

Orchids like bright, indirect low-cal. "Most important—no called-for hot lord's day," says Gerritsen. "Don't put it in straight sun, which tin can cook it."

Tip: N-facing windows tend not to get plenty light to satisfy an orchid ("unless the edifice across the street is white or a shiny fabric and you get a lot of reflected light," says Gerritsen).

Above: If y'all put a moth orchid in a west-facing window, the trouble is information technology gets dominicus in the hot part of the day. "Move it farther back from the window or put a sheer curtain between the orchid and the window," says Gerritsen.

Should I put my orchid in a Swiss-cheese pot with the holes?

It'south not necessary to utilize an open-air orchid pot if your establish's roots have skilful air apportionment in a pot. The Swiss-cheese pots attempt to replicate orchid-growing conditions in the wild, where the plants either grow visibly on the surface of trees (epiphytes with roots attached to the bark of  tree branches) or on rocks, with their roots working their way into crevices.

Tip: Give roots lots of air by tucking them into medium-size pieces of bark.

In a higher place: Fertilize your orchid every 2nd time you lot h2o it, with a diluted solution of fertilizer. "It the instructions say one teaspoon per fallow, I apply half-force no thing whether it'southward a general flower fertilizer or an orchid fertilizer," says Gerritsen.

How oft should I water my orchid?

"First, you lot want to be careful when it's in bloom that the roots take a run a risk to dry out between waterings," says Gerritsen. "Don't permit it sit in a bowl of water."

Tip: Water a Phalaenopsis once a week and let the water run out from its roots so they don't rot.

Above: Orchids like humidity. Where many grow, the humidity level is from 70 to ninety percent and they are in fog for much of the solar day. "Indoors, identify the orchid'south pot on a tray of pebbles with water around the pebbles (and then the found itself isn't sitting in a tray of water) and the evaporation will increment humidity," says Gerritsen.

Can I take my orchid outdoors in nice weather?

Orchids like the increased air apportionment and the temperature change they get outdoors. "Put them in a place where they are not in directly dominicus, nether a tree so they don't get overheated," says Gerritsen. "They do very well outside. Bring them indoors for the cool months."

Tip: Outdoors, pick a protect place where wind won't blow over your orchid. If you have no shade, buy shade material to brand a little canopy to protect your orchid from likewise much sunlight.
