How to Care for a Potted Orchid
A potted phalaenopsis orchid flowers for at least a month, often longer, if you water it thoroughly and then leave it until the mix is nearly dry. Adore Flowers works with phalaenopsis stems in Downtown Los Angeles, and this guide is for the plant on your windowsill.
Almost every orchid that dies indoors dies from too much water rather than too little. The plant hides the damage for weeks, so by the time the leaves go limp the roots have already gone. Get the watering rhythm right and a phalaenopsis is among the least demanding plants in a Los Angeles home.
How often should you water a potted orchid?
Water thoroughly, then not again until the mix is nearly dry. That is the American Orchid Society's rule, and it replaces every schedule you have been given.
In practice the interval swings with the weather. The Society puts it at every other day in the heat of summer in a dry climate, and as long as every 10 days in cool conditions.
Take the pot to the sink and run room-temperature water through the bark until it drains freely. Let it finish draining before it goes back into its outer pot, because standing water is what rots the roots.
Is the ice cube method a good idea?
It is a blunt way to measure water rather than a technique. Three cubes wet a small patch of bark and leave the rest of the root ball dry.
The published guidance asks for a thorough soak followed by a near-dry period, and cubes deliver neither half of that cycle. A minute at the sink once a week does the same job properly.
What does a phalaenopsis need indoors?
Bright indirect light, warm days, cooler nights, and a potting mix that dries between waterings. The table holds the published figures.
What a phalaenopsis needs indoors, in the figures its growers publish.
| Factor | What the guidance says | Source |
|---|---|---|
| Light | An east window is ideal in the home; shaded south or west windows are acceptable | American Orchid Society |
| Day temperature | 75 to 85F or more during the day | American Orchid Society |
| Night temperature | Above 60F at night; 55F for several weeks in autumn initiates flower spikes | American Orchid Society |
| Watering | Water thoroughly, then not again until nearly dry: every other day in dry summer heat, up to every 10 days in cool conditions | American Orchid Society |
| Humidity | 50 to 80 percent | American Orchid Society |
| Fertilizer | Quarter strength with every watering in warm, humid conditions; twice a month at weak strength when cooler or overcast | American Orchid Society |
| Flower duration | At least a month or longer with proper care | University of Maryland Extension |
| Repotting | Usually every 1 to 3 years, into a porous mix | American Orchid Society |

How do you know when an orchid needs water?
Read the roots rather than the calendar. Plump and green means the plant has drunk; silvery grey means it is ready for the next soak.
Weight works as a second check. A pot that still feels heavy a week after watering is holding more water than the plant can use, which usually means the mix has broken down and needs replacing.
The American Orchid Society calls for a porous mix and repotting usually every 1 to 3 years, and old bark that has turned to compost is the quiet cause of most root loss.
Where should an orchid sit in a Los Angeles home?
An east window, or a few feet back from a brighter one. Our afternoon sun is strong enough to scorch a leaf through glass, so keep the plant off a south or west sill in summer.
The leaves report on the light. A medium olive green is right, dark green means too little, and a yellowish or reddish cast means too much.
Los Angeles air also runs dry against the 50 to 80 percent humidity the plant wants. A shallow tray of pebbles and water under the pot, with the pot above the waterline, helps more than misting.
How do you get an orchid to bloom again?
Cool nights do the work. The American Orchid Society says night temperatures to 55F are desirable for several weeks in autumn to initiate flower spikes.
An LA autumn supplies that near a window at no cost, which is the one part of this climate that suits orchids better than cut flowers. A spike that has gone brown and dry is spent, so cut it off at the base and let the plant build strength.
Do you sell potted orchids in Los Angeles?
No. We are a cut flower studio, and phalaenopsis stems appear inside our vase arrangements rather than as potted plants, set in a permanent vessel from $150 in four sizes.
An orchid stem is the piece I use when an arrangement needs one clean architectural line. Order before 11 AM, Monday through Saturday, for same-day delivery across 35 Los Angeles County neighborhoods, including Beverly Hills in 90210 and Silver Lake near Sunset Junction.
