You got a moth orchid as a vacation souvenir. Or equally a birthday present. Maybe it came from your grandmother, who also informed you that the plant's horticultural name is Phalaenopsis and that there are dozens of species. Just this is not what concerns yous: the problem is the flowers have shriveled, leaving behind a bare fasten and a couple of waxy light-green leaves in a pot. You wonder, "When my orchid bloom again?"

Mary Gerritsen understands your pain. Orchid whisperer Gerritsen coaxes hers to flower once more every twelvemonth—and shares her acme plant intendance tips hither.

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 accept are ones someone got as gift and the blossom cruel off and then they said, 'Here,' and gave information technology to me."

Higher up: "Most Phalaenopsis are shipped here from Taiwan, flattened in a container ship, smushed in Sphagnum moss," says Gerritsen. "When they get hither, to get them to bloom they are grown in special circumstances involving light and temperature." Your job: replicate those circumstances at domicile.

What should I practise when my orchid stops blooming?

The goal is to get your moth orchid to flower at to the lowest degree once a year, for several months. (Some of Gerritsen's volition bloom for eight to ten months.)

First, cut off the old flower stalk at the base of operations of the plant. 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 month's worth of  daily temperature drops of at to the lowest degree 10 degrees from day to dark.

"In your house, you tend non to have large drops; the temperature tends to be fix 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 sun goes down, the heat volition drop and the common cold will stimulate it to re-flower.

Tip: "My room has a window that faces s, has no heat vent, and basically has glass on 2 sides and a skylight, so information technology gets a temperature spike during the day," Gerritsen says.

To a higher place: In the wild, many moth orchids thrive in humidity and moist climates, in filtered sunlight beneath a awning of trees. Keep them out of harsh, directly sunlight.

When should I re-pot my orchid?

"Often the ones from the florist have damaged roots," says Gerritsen. "Make sure it's not washed upward as a throwaway, stuffed in a pot with a agglomeration of pebbles, reindeer moss, and no drainage."

Tip: Re-pot, after an orchid stops blooming. Take information technology gently from its pot, milk shake off the sometime bark, and cut off whatsoever dead roots with a sterile razor blade or scissors. "Don't brand the fault of putting into a bigger pot, because orchids don't similar that," says Gerritsen. "They like to have their roots crowded in a small space." Then pot it into a same-size pot, holding 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 help drainage and air circulation. A 1-gallon bag of Douglas Fir Bark For Orchids is $23.99 from Amazon.

Higher up: Once established, a moth orchid volition flower year after year. "I accept a friend in Washington, D.C. who I have been visiting for 25 years and she has had the same Phalaenopsis in her window all that time, and it blooms every year," says Gerritsen.

How much lord's day does a moth orchid need?

Orchids like bright, indirect light. "Well-nigh important—no burning hot dominicus," says Gerritsen. "Don't put it in direct dominicus, which can cook information technology."

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

In a higher place: If you lot put a moth orchid in a west-facing window, the trouble is it gets lord's day in the hot part of the day. "Motility it farther back from the window or put a sheer curtain betwixt the orchid and the window," says Gerritsen.

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

It's not necessary to use an open-air orchid pot if your plant'southward roots take adept air circulation in a pot. The Swiss-cheese pots try to replicate orchid-growing weather condition in the wild, where the plants either grow visibly on the surface of trees (epiphytes with roots fastened to the bark of  tree branches) or on rocks, with their roots working their style into crevices.

Tip: Requite 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 h2o information technology, with a diluted solution of fertilizer. "It the instructions say ane teaspoon per fallow, I use half-strength no matter whether it'south a general flower fertilizer or an orchid fertilizer," says Gerritsen.

How frequently should I water my orchid?

"First, y'all desire to exist careful when information technology'southward in bloom that the roots have a chance 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 allow the water run out from its roots and so they don't rot.

Above: Orchids like humidity. Where many grow, the humidity level is from seventy to 90 percent and they are in fog for much of the twenty-four hour period. "Indoors, place the orchid'due south 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 increase humidity," says Gerritsen.

Can I take my orchid outdoors in nice conditions?

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

Tip: Outdoors, pick a protect place where wind won't blow over your orchid. If yous take no shade, buy shade cloth to brand a lilliputian canopy to protect your orchid from too much sunlight.
