The Complete Orchid Care Guide
At Flora Clay, we've been growing orchids in our San Diego greenhouse since 2001. Over two decades and tens of thousands of orchids, we've learned what keeps these plants thriving and what causes them to struggle. This guide distills everything we know about orchid care into a single, practical reference. Whether you just brought home your first Phalaenopsis or you're trying to coax a stubborn plant into reblooming, you'll find what you need here.
Because we grow our orchids locally rather than shipping them across the country, our plants arrive stronger and better acclimated to Southern California conditions. That head start matters and the care advice in this guide reflects real experience with orchids grown and maintained in the LA climate.
Watering Your Orchid
Overwatering is the single most common reason orchids decline. Orchids store moisture in their roots and pseudobulbs, so they need time to dry out between waterings. In Los Angeles, where indoor environments tend to run warm and dry, it's tempting to water more frequently but restraint is key.
How Often to Water
For most indoor environments, watering once every 7 to 10 days works well. In summer, when temperatures are higher and air conditioning runs constantly, you may need to water slightly more often. In winter, scale back as growth naturally slows. The goal is to let the potting medium approach dryness without letting roots desiccate completely.
The Root Check Method
Rather than watering on a fixed schedule, check the roots before every watering. This is the single best habit you can develop as an orchid owner. Healthy, well-hydrated roots appear green or silver-gray and feel firm. When they begin to lighten and look wrinkled or papery, it's time to water. If you have a clear nursery pot (which we include with every Flora Clay orchid), you can monitor root health without disturbing the plant.
How to Water Properly
Take the pot to your sink and run room-temperature water gently through the potting medium for about 30 seconds. Allow all excess water to drain fully before returning the pot to its tray or decorative planter. Never leave your orchid arrangement sitting in standing water this is the fastest route to root rot. Use filtered or room-temperature tap water. Cold water straight from the faucet can shock the roots.
LA Apartment Tip: Air conditioning significantly reduces indoor humidity, which accelerates how quickly orchid bark dries out. During summer, check your orchid more frequently and consider placing a humidity tray filled with pebbles and water beneath the pot. If your orchid sits near an AC vent, move it cold air blasts are one of the top causes of bud drop in LA apartments.
Finding the Right Light
Best Window Positions
East-Facing Windows - Ideal
East-facing windows receive gentle morning light at the perfect intensity for most orchid varieties. Temperatures remain stable throughout the day. This is the best position for Phalaenopsis (moth orchids), the most popular variety we sell at Flora Clay and the most common orchid in homes across LA.
West-Facing Windows - Very Good
West-facing windows catch strong afternoon light. This works well as long as your orchid is set back slightly from the glass or a sheer curtain diffuses the direct rays. Dendrobiums and Cattleyas, which enjoy higher light levels, do particularly well in west-facing spots.
South-Facing Windows - Use Caution
South-facing windows receive intense, direct sunlight for much of the day. Place your orchid at least 3 to 4 feet from the glass, or use a sheer curtain to filter the light. Yellowing or bleached patches on leaves indicate too much direct sun.
North-Facing Windows - Supplement If Needed
North-facing windows rarely provide sufficient light for orchids to bloom reliably. If this is your only option, supplement with a small LED grow light placed 12 to 18 inches above the plant for 10 to 12 hours per day.
How to Read Your Orchid's Leaves
Your orchid's foliage tells you whether it's getting the right amount of light. Dark green, almost olive-colored leaves indicate insufficient light. Bright, medium green leaves with a slight yellow-green tint signal healthy light levels. Yellow or washed-out patches suggest too much direct sun move the plant back or add a sheer curtain.
Temperature & Humidity
Ideal Temperature Range
Most orchids kept in homes are Phalaenopsis, which thrive between 65°F and 80°F a range that aligns naturally with most indoor LA environments. Daytime temperatures of 70°F to 80°F with a slight drop at night are ideal for both growth and blooming.
Air Conditioning and Heating Vents - Keep Your Distance
Never place orchids directly beneath or adjacent to AC vents. Cold blasts of air dry out foliage and roots rapidly and can trigger bud blast (buds dropping before they open). Keep orchids equally distant from heating vents, which create excessively dry heat that stresses the plant. Windowsills can also experience significant temperature swings warm during the day, cooler at night in winter. Monitor conditions near glass during colder months.
Managing Humidity
Los Angeles has naturally low ambient humidity, and air conditioning reduces it further. Most orchids prefer humidity between 50% and 70%, which is higher than the average LA interior. Simple solutions include placing your pot on a shallow tray filled with pebbles and water (with the base of the pot sitting above the waterline), grouping your orchid with other plants so their collective transpiration raises local humidity, or misting aerial roots lightly in the morning.
LA Apartment Tip: Every Flora Clay orchid arrangement comes in a ceramic planter that helps moderate moisture around the root zone a meaningful upgrade from disposable plastic nursery pots that dry out quickly in LA's low humidity.
Common Orchid Varieties & Their Care
Not all orchids need the same care. Here's a quick reference for the varieties we grow most often in our San Diego greenhouse.

When and How to Repot Your Orchid
Orchids need repotting when their growing medium breaks down, when roots begin escaping the pot in significant numbers, or when the plant becomes top-heavy and unstable. For most orchids, this happens every one to two years.
Signs Your Orchid Needs Repotting
Watch for these indicators: the bark or moss medium has decomposed and no longer provides adequate drainage; roots are growing densely over the rim with no room left inside the pot; the plant wobbles or tips easily when watered; or you notice a musty smell from the potting medium, which suggests decomposition or trapped moisture.
Step-by-Step Repotting
Wait until blooms have dropped and the plant enters its rest phase. Gently remove the orchid from its existing pot, shaking away old potting medium from the roots. Trim any dead, mushy, or hollow roots with sterile scissors healthy roots are firm and white or green. Place the orchid in a new pot one size larger (clear plastic nursery pots are ideal for monitoring root health). Fill around the roots with fresh orchid bark, pressing gently to provide stability without compacting. Do not water for 5 to 7 days after repotting this encourages roots to seek moisture and establish in the new medium.

How to Get Your Orchid to Rebloom
This is the most common question we hear from customers: “My orchid finished blooming how do I get flowers again?” The answer almost always comes down to one factor: a temperature differential between day and night.
The Temperature Trigger
Phalaenopsis orchids require a drop in nighttime temperature to initiate a new bloom spike. In climate-controlled environments where temperatures stay consistent year-round, this natural signal is absent which is why reblooming can stall without deliberate intervention.
Creating the Temperature Differential
In autumn and early winter, move your orchid near a window overnight where temperatures naturally drop to around 55°F to 60°F. Maintain this cooler night temperature for 4 to 6 weeks while keeping daytime temperatures in the normal 70°F–80°F range. In LA, a covered patio, an unheated room, or positioning near a single-pane window on cooler nights can provide the necessary drop.
After the Spike Appears
Once a new bloom spike emerges typically a green, arching shoot from the base of a leaf move the plant back to its regular position and resume normal care. Avoid rotating the plant once the spike is forming, as orchids orient their growth toward their primary light source. After providing the temperature trigger, expect 3+ weeks before flowers appear. Patience pays off.
Troubleshooting Common Orchid Problems
Yellow Leaves
Yellow leaves at the base of the plant are normal older leaves naturally yellow and drop as the plant matures. If younger, middle leaves are yellowing, this typically indicates overwatering, too much direct sun, or nutrient deficiencies. Check your watering schedule and light position before adjusting fertilizer.
Wrinkled or Limp Leaves
Soft, wrinkled leaves mean the plant is losing more moisture than it's absorbing. Check the roots: if they appear dry and gray-white, increase watering frequency slightly. If roots appear brown and mushy, root rot has set in and the plant needs immediate repotting (see repotting section above).
Bud Blast (Buds Dropping Before Opening)
In LA homes, bud blast is most commonly caused by cold air from AC vents, sudden temperature changes, low humidity, or exposure to ethylene gas from nearby ripening fruit. Relocate the plant away from air vents and fruit bowls, and maintain stable conditions until blooming is complete.
Root Rot
Soft, brown, hollow roots signal root rot from overwatering or poor drainage. Repot immediately, trimming all damaged roots. After repotting, wait a full week before watering and ensure the pot has adequate drainage holes.
No New Growth
If your orchid hasn't produced new leaves or roots in several months, assess its light, temperature, and feeding schedule. Ensure it's receiving bright indirect light, temperatures are within range, and you're fertilizing every two weeks during the active growing season (spring and summer in LA).
