You wonder, "When my orchid flower again?"

"When they get hither, to become them to bloom they are grown in special circumstances involving light and temperature." Your task: replicate those circumstances at home.

What should I do when my orchid stops blooming?

The goal is to go your moth orchid to bloom at to the lowest degree once a yr, for several months. (Some of Gerritsen'southward will bloom for eight to x months.)

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

"In your house, you lot tend not to have big drops; the temperature tends to be prepare to a steady 68 degrees," says Mary. So put your orchid in a room that gets a little cold by the window—and put your orchid in the window. When the sun goes down, the oestrus volition drop and the cold will stimulate it to re-bloom.

Tip: "My room has a window that faces due south, has no estrus vent, and basically has glass on two sides and a skylight, so information technology gets a temperature spike during the twenty-four hour period," Gerritsen says.

When should I re-pot my orchid?

"Often the ones from the florist have damaged roots," says Gerritsen. "Make sure it's 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 information technology gently from its pot, milk shake off the one-time bark, and cut off whatever expressionless roots with a sterile razor blade or scissors. "Don't make the mistake of putting into a bigger pot, because orchids don't like that," says Gerritsen. "They like to have their roots crowded in a pocket-sized space." And so pot it into a same-size pot, holding its leaves and so the roots dangle into the pot. Add together bawl and gently mix the pieces effectually its roots to concord them snugly.

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

In a higher place: One time established, a moth orchid volition bloom year afterward yr. "I take a friend in Washington, D.C. who I accept been visiting for 25 years and she has had the same Phalaenopsis in her window all that time, and information technology blooms every year," says Gerritsen.

How much sun does a moth orchid need?

Orchids like bright, indirect light. "Most important—no burning hot sun," says Gerritsen. "Don't put it in directly lord's day, which can cook it."

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

Higher up: If you put a moth orchid in a west-facing window, the problem is it gets sun in the hot role of the solar day. "Motion information technology 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?

Information technology'southward not necessary to apply an open-air orchid pot if your plant'south roots have practiced air circulation in a pot. The Swiss-cheese pots attempt to replicate orchid-growing atmospheric 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 way into crevices.

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

Above: Fertilize your orchid every second time you lot water it, with a diluted solution of fertilizer. "It the instructions say ane teaspoon per dormant, I use half-forcefulness no matter whether it'south a general flower fertilizer or an orchid fertilizer," says Gerritsen.

How often should I water my orchid?

"Outset, yous want to be careful when it'southward in blossom that the roots have a chance to dry out between waterings," says Gerritsen. "Don't let it sit in a basin of water."

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

Above: Orchids like humidity. Where many abound, the humidity level is from 70 to 90 per centum and they are in fog for much of the twenty-four hours. "Indoors, place the orchid's pot on a tray of pebbles with water around the pebbles (and then the plant 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 weather?

Orchids like the increased air circulation and the temperature change they become 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 exterior. Bring them indoors for the absurd months."

Tip: Outdoors, option a protect place where wind won't blow over your orchid. If you have no shade, purchase shade cloth to brand a little canopy to protect your orchid from as well much sunlight.
