Getting My Orchid to Bloom Again

Yous got a moth orchid every bit a holiday gift. Or every bit a birthday present. Maybe it came from your grandmother, who besides informed yous that the found'due south horticultural proper name is Phalaenopsis and that there are dozens of species. Simply this is not what concerns you: the problem is the flowers accept shriveled, leaving behind a bare spike and a couple of waxy light-green leaves in a pot. You wonder, "When my orchid bloom over again?"

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

The writer of A Bay Area Guide to Orchids and their Civilisation has been growing orchids since the 1970s and says: "Most of the indoor orchids I have are ones someone got equally gift and the flower vicious off and so they said, 'Here,' and gave it to me."

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

What should I do when my orchid stops blooming?

The goal is to get your moth orchid to flower at least once a twelvemonth, for several months. (Some of Gerritsen's will bloom for eight to ten months.)

First, cut off the former flower stem at the base of operations of the found. Then put your moth orchid in a room in your house that simulates the atmospheric condition that will cause it to flower again. For starters, it will need a calendar month's worth of  daily temperature drops of at least 10 degrees from day to nighttime.

"In your house, you 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 lilliputian cold by the window—and put your orchid in the window. When the lord's day goes down, the estrus will drop and the cold volition stimulate it to re-bloom.

Tip: "My room has a window that faces south, has no heat vent, and basically has drinking 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?

"Ofttimes the ones from the florist have damaged roots," says Gerritsen. "Brand sure it'southward not done upwards 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 information technology gently from its pot, shake off the one-time bark, and cut off any dead roots with a sterile razor bract or pair of scissors. "Don't make the mistake 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 it into a same-size pot, holding its leaves and so the roots dangle into the pot. Add bark and gently mix the pieces effectually its roots to concord them snugly.

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

How much sun does a moth orchid demand?

Orchids like bright, indirect light. "Most of import—no burning hot sun," says Gerritsen. "Don't put information technology in direct lord's day, which can melt it."

Tip: Due north-facing windows tend not to go enough light to satisfy an orchid ("unless the building across the street is white or a shiny material and you get a lot of reflected low-cal," says Gerritsen).

Above: If you put a moth orchid in a w-facing window, the problem is it gets lord's day 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's non necessary to use an open up-air orchid pot if your institute's roots have good air circulation in a pot. The Swiss-cheese pots attempt to replicate orchid-growing weather condition 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.

To a higher place: Fertilize your orchid every second time you lot water information technology, with a diluted solution of fertilizer. "It the instructions say one teaspoon per dormant, I use half-strength no affair whether it's a general flower fertilizer or an orchid fertilizer," says Gerritsen.

How often should I water my orchid?

"First, you want to be conscientious when it'southward in blossom that the roots accept a take a chance to dry out between waterings," says Gerritsen. "Don't let it sit in a bowl of water."

Tip: Water a Phalaenopsis in one case a week and allow the h2o run out from its roots so they don't rot.

In a higher place: Orchids like humidity. Where many grow, the humidity level is from 70 to 90 per centum and they are in fog for much of the day. "Indoors, identify the orchid's pot on a tray of pebbles with water around the pebbles (so the institute itself isn't sitting in a tray of water) and the evaporation will increment humidity," says Gerritsen.

Can I take my orchid outdoors in prissy weather?

Orchids similar the increased air circulation and the temperature change they go outdoors. "Put them in a place where they are not in direct lord's day, under a tree so they don't get overheated," says Gerritsen. "They do very well outside. Bring them indoors for the cool months."

Tip: Outdoors, selection a protect place where wind won't blow over your orchid. If you have no shade, buy shade fabric to make a niggling canopy to protect your orchid from too much sunlight.
