Care Guide: Planting, Soil & Watering
Overview: Beallara is a hybrid orchid grown in deep shade in an open, fast-draining bark-based medium rather than soil. It wants moderate, even moisture with high humidity and warm days around 20–30°C cooling to about 15–20°C at night, with well-aerated roots that are never left waterlogged.
Quick Care Requirements
| Requirement | Ideal Condition |
|---|---|
| Planting Season | Year-round, avoiding winter; repot as it outgrows its pot (about once a year) |
| Growth Rate | Slow |
| Soil Type | Open orchid medium – bark or bark chips (not soil), in a transparent, snug pot with sharp drainage and airflow to the roots |
| Water Need | Moderate – keep the medium lightly moist with room-temperature, clean water; never waterlogged |
Planting & Establishment
- Best Planting Season: Pot or repot year-round except in winter; the roots renew roughly once a year, so refresh the medium then rather than potting straight into a large container.
- How to Pot:
- Pot & Container: Use a transparent pot only slightly larger than the roots – avoid oversizing, which stays too wet.
- Growing Medium: Use fresh bark or bark chips with pieces of Styrofoam for airflow to the roots, and replace the medium before it breaks down into acidic compost.
- Setting the Plant: Cut away any dead roots when repotting and settle the plant so its base sits at the surface of the bark, not buried.
- Growth Speed & Expectations: Slow, reaching about 0.5–1.2 m.
Soil, Watering & Drainage Care
- Medium & Drainage Needs: A coarse, airy, fast-draining bark medium is essential; the transparent pot lets you watch the roots and moisture, and bark plus Styrofoam keep roots aerated to prevent rot.
- Watering Schedule & Technique:
- Young / Newly Potted: Water with clean, room-temperature water (rainwater is ideal), keeping the medium lightly moist while it re-roots.
- Established: Water when the medium nears dryness, always with tepid clean water, and let it drain freely.
- Seasonal Adjustments: Keep humidity high year-round and provide the cooler nights that trigger bloom; water a little less in cool, low-light spells.
Climate, Light & Hardiness
Beallara is a hybrid orchid suited to subtropical or mediterranean climates, a greenhouse, or houseplant culture, needing warm days and distinctly cooler nights - that day/night temperature swing actually helps trigger flowering. It has no meaningful outdoor frost tolerance, though it can briefly withstand a wider range than many orchids.
Quick Climate Specifications
| Climate Zones | Subtropical, mediterranean, or greenhouse/houseplant |
| USDA Hardiness Zones | 10b–12 |
| Optimal Temp Range | Day approximately 20–30°C (68–85°F); night approximately 15–20°C (59–68°F), with cooler nights needed to induce bloom |
| Approx. Survival Minimum | Can briefly tolerate roughly 3–35°C (37–95°F), though sustained exposure near either extreme is stressful |
| Frost Tolerance | None |
| Light Conditions | Full Shade (bright, indirect light) |
Sunlight & Light Exposure
Optimal Light Setup
Bright, indirect light rather than direct sun.
Temperature Extremes & Hardiness
USDA Hardiness & Regional Limits
Zone 10b–12 reflects a warm-climate orchid with essentially no outdoor frost tolerance; a distinct day-to-night temperature drop is actually beneficial, helping trigger blooming.
Cold Damage & Winter Protection
Keep well above its roughly 3°C (37–38°F) brief-survival floor; sustained cold is damaging even if a brief dip is tolerated.
Frost Sensitivity
No frost tolerance.
Extreme Heat Tolerance
Can briefly tolerate heat up to around 35°C (95°F), though sustained extreme heat is stressful.
Wind, Humidity & Microclimate
Humidity Preferences
Needs consistently high humidity and moist (not soggy) conditions.
Microclimate Recommendations
A greenhouse or bright indoor spot with a real day/night temperature swing supports both healthy growth and reliable flowering; avoid planting outdoors in winter.
Growing in Pots, Balconies & Indoors
Beallara (Beallara) is a larger orchid (about 0.5-1.2 m) and a genuine houseplant – the grower confirms it grows well indoors, and orchids are almost always grown in a pot rather than open ground. Give it bright, indirect light near a window and it makes a rewarding, long-flowering indoor plant.
Quick Details
- Container Size: A pot only about 20-40% larger than the root ball – orchids like to be snug
- Indoor Suitability: Yes – a true houseplant in bright, indirect light
- Best Spot: Bright, indirect light – a well-lit spot out of direct sun
- Soil & Drainage: Never ordinary potting soil – use a coarse, open orchid medium (bark or cork chips) with lots of drainage holes
- Watering in Pots: Water moderately – water when the medium is nearly dry, then let it drain; let excess drain away and never leave the pot standing in water
Indoors & On the Windowsill
- A true houseplant: The grower confirms it thrives indoors – keep it near a bright window but out of harsh, direct midday sun.
- Windowsill growing: An east or shaded-south window is ideal; a clear pot lets you watch the roots and see when to water.
- Overwintering: As a tropical plant it is happiest indoors year round in cool climates – keep it warm, bright and away from cold draughts and frost.
On a Balcony or Patio
- Summering outdoors: It can spend warm spells on a shaded, sheltered balcony or patio in bright but indirect light – protect it from direct sun, drying wind and any chill. Pots and open orchid media dry quickly, so check moisture often.
Choosing the Pot, Soil & Long-Term Care
- Pot & drainage: A snug pot with many holes; a transparent pot is useful for watching the roots. Never let it sit in standing water – the fastest route to rot.
- Medium: A coarse, free-draining orchid mix of bark or cork chips (some more terrestrial types appreciate a little added coir or humus), not garden soil.
- Feeding & water quality: Feed with a dilute orchid fertiliser a few times a year; where possible use rain or distilled water, which orchids prefer.
- Repotting: Refresh the medium about every two years – bark breaks down and loses structure over time – and pot on when roots fill the container.
Fertilizing & Feeding
A light feeder: this fragrant hybrid orchid grows in a bark or cork mix with a small root system, so it needs only weak, regular feeding rather than the heavier feeding a soil-grown garden plant might need – its long bloom period is driven mainly by day-night temperature contrast, not by extra fertilizer.
Quick Fertilizing Specs
| Feeding Level | Light feeder |
|---|---|
| Main Nutrient Priority | Weak, balanced feeding through active growth and bloom; avoid high-phosphorus bloom boosters |
| Best Feeding Period | The active growing months leading into the spring and autumn bloom cycles |
| Organic Options | A diluted organic liquid feed made for container or epiphytic plants can substitute for a synthetic fertilizer |
| Micronutrients | Usually supplied by a complete, weak fertilizer formulated for orchids or container plants |
| Soil pH | Grown in an open bark or cork mix rather than soil; refresh the medium before it breaks down and turns acidic |
Feeding by Growth Stage
Active growth
Support new leaf and pseudobulb growth on this hybrid orchid as it comes out of rest and builds toward its next bloom.
| Nutrient direction | A weak, balanced fertilizer suited to bark or cork-grown epiphytic hybrids. |
|---|---|
| Timing | Through the warmer months as new growth develops. |
| Frequency | Light, regular feeding while new growth is visible; ease off once growth pauses. |
| Fertilizer types | A weak, balanced fertilizer diluted for container-grown orchids, A fertilizer suited to bark or cork-chip mixes |
| Routine trace nutrients | iron, manganese |
| Precautions | Keep fertilizer weak – concentrated feeding can damage this orchid’s fine roots and the bark medium’s ability to drain. |
Spring and autumn bloom
Support bud formation and this hybrid’s fragrant, long-lasting bloom, which forms when nights turn cooler than days.
| Nutrient direction | Continue the same weak, balanced fertilizer through bud formation and bloom rather than switching to a high-phosphorus product. |
|---|---|
| Timing | Spring and autumn, whenever day-night temperature contrast triggers bud set. |
| Frequency | Maintain the same light, regular feeding through bud formation and the extended bloom; flowering is not a reason for heavier feeding. |
| Fertilizer types | The same weak, balanced fertilizer used during active growth, Avoid high-phosphorus bloom-booster products |
| Routine trace nutrients | iron, manganese |
| Precautions | Do not increase fertilizer strength during the long bloom period; balanced feeding supports both the current bloom and the growth needed for the next one. |
Rest between bloom cycles
Let growth slow during the gap between bloom cycles, when there is little day-night temperature contrast to drive new growth or budding.
| Nutrient direction | None – withhold fertilizer while growth is minimal. |
|---|---|
| Timing | The periods between the spring and autumn bloom cycles, including the hottest and coldest stretches of the year. |
| Frequency | No feeding at this stage. |
| Fertilizer types | No feeding at this stage; feeding begins again once active growth resumes. |
| Precautions | Do not fertilize during this rest period; keep watering light but do not let the medium stay fully dry for long stretches. |
Nutrient Deficiency Signs & Corrections
New growths come in smaller than previous ones and older leaves gradually fade to pale yellow-green.
| Possible causes | extended under-feeding in a bark medium with little nutrient reserve of its own, low light limiting overall growth and nutrient demand, root loss from past overwatering limiting nutrient uptake |
|---|---|
| Appears first on | older leaves and the size of newest growths |
| What to check | feeding history and strength, root condition, light levels |
| Possible correction | Resume a weak, balanced feeding routine through the active growth period. |
Leaf margins and tips show yellow or scorched-looking browning while flowering is weaker or shorter-lived than expected.
| Possible causes | a feeding program low in potassium relative to nitrogen over time, salt buildup in the bark medium disrupting nutrient balance, root damage limiting overall nutrient uptake |
|---|---|
| Appears first on | older leaf margins and tips |
| What to check | fertilizer balance and feeding history, signs of salt buildup on the medium surface, root condition |
| Possible correction | Use a balanced fertilizer that supplies adequate potassium and periodically flush the medium to prevent salt buildup. |
New leaves come in pale yellow while the veins remain distinctly greener than the surrounding tissue.
| Possible causes | a medium or water source that has pushed the root zone outside the range this hybrid prefers, waterlogged or poorly aerated medium limiting root function, a long stretch without any micronutrient feeding |
|---|---|
| Appears first on | newest leaves |
| What to check | medium drainage and aeration, water quality, recent feeding history |
| Possible correction | Address drainage first, then apply a chelated iron product per its label if chlorosis continues. |
Flower buds form but shrivel and drop before opening, especially during the plant’s long bloom period.
| Possible causes | a boron shortfall in the feeding program, since this micronutrient is needed in only very small amounts but plays a role in bud and flower development, sudden shifts in humidity or watering while buds are developing, physical disturbance or temperature swings during bud development |
|---|---|
| Appears first on | developing flower buds |
| What to check | feeding history and whether a complete fertilizer with micronutrients has been used, recent watering and humidity consistency, recent handling or temperature swings |
| Possible correction | If a boron shortfall is suspected, correct it only with a product labeled for the purpose and follow its label closely, since boron has a narrow margin between too little and too much. |
Pruning, Training & Seasonal Maintenance
Beallara is a sympodial hybrid orchid with no structural pruning needs; its own bloom can last up to three months once triggered by a day/night temperature differential, so – unlike orchids with a short, sharply defined bloom window – sanitary pruning here is done year-round as needed rather than tied to one fixed post-bloom date. The two tasks are the same throughout the year: removing dead leaves and cutting back bloom stems once they have genuinely finished, not on a preset calendar.
Quick Pruning & Maintenance Specs
| Pruning Tolerance | Low (sanitary only, no structural cutting) |
| Primary Pruning Window | Year-round, as leaves yellow and as individual bloom stems finish (watch for the end of an up-to-3-month bloom before cutting) |
| Typical Frequency | Ongoing, checked regularly rather than seasonal |
| Main Objective | Plant hygiene, not shaping |
| Young Plant Priority | No cutting beyond removing damaged leaf tissue |
| Mature Plant Priority | Remove dead leaves and fully spent bloom stems |
| Best Tool Type | Precision snips, sterilized between plants |
Pruning by Plant Age & Size
Newly Established
Do not cut back a young division; let it build pseudobulbs before removing anything beyond obviously dead tissue.
Young / Formative
No structural training applies to this sympodial hybrid.
Mature / Established
Remove dead leaves as they occur, and cut back a bloom stem only once it is genuinely spent – given flowering can run up to three months, check before assuming a stem is finished.
Special Growth to Remove
Dead/yellowed leaves (any time) and bloom stems (only once flowering on that stem has fully finished, not on a fixed calendar date).
Container & Small-Space Pruning
Grown in pots in an open bark/cork medium; repot before roots outgrow the pot rather than jumping to an oversized one, and trim any dead or rotted roots at that time with the same sterile tool.
Tools
Precision snips for both leaf and bloom-stem removal – no woody tissue to warrant anything larger.
Tool Hygiene & Disease Risk
High-risk: as with other orchids, virus transmission between plants via cutting tools is a real concern. Disinfect the blade between each plant.
Cut Placement & Technique
Cut a spent bloom stem back near its base once it is confirmed finished; remove dead leaves at the base rather than tearing them off.
Heavy Pruning & Rejuvenation
Not applicable – no hard cutting back; renewal comes from the plant producing new pseudobulbs on its own.
Post-Pruning Care
No feeding change after routine removal; maintain the temperature differential between day and night that triggers reblooming, and keep humidity high.
Common Pruning Mistakes
Cutting a bloom stem too early, mistaking a pause for the end of what can be a three-month flowering run; reusing an unsterilized blade across plants.
When NOT to Prune
Do not cut a bloom stem while it may still be actively flowering; avoid pruning and repotting at the same stressed moment.
Recommended Tools (by task)
- Removing dead leaves and fully spent bloom stems (thin, soft tissue) – precision_snips: the only cutting tool this hybrid orchid needs.
- Sterilizing the blade between plants – blade_disinfectant: orchid virus transmission via tools is a genuine, documented risk.
Propagation Guide
Beallara, a complex intergeneric orchid hybrid, is propagated almost exclusively by dividing established clumps of pseudobulbs – site data lists vegetative reproduction (not seed) as the way to start this plant, and confirms seed is hard. Difficulty is Moderate.
Quick Propagation Specs
| Best Propagation Method | Division of pseudobulb clumps |
| Alternative Methods | Backbulb propagation |
| Propagation Difficulty | Moderate |
| Seed True-to-Type | Hybrid offspring vary – not practiced in home propagation; per site data vegetative propagation is required to keep this hybrid true |
| Vegetative True-to-Type | Yes |
| Best Propagation Season | Spring, avoiding winter (per site planting-season guidance) |
Division, Offsets, Pups & Suckers
Divide established clumps at the start of active spring growth; site data advises against planting in winter, so winter division is best avoided as well. Each division should include several (commonly three or more) healthy pseudobulbs with a live growing point and functional roots for reliable establishment. Pot divisions into fresh bark/cork mix sized to the roots, keep warm and humid, and avoid oversized pots until the new growth is established. Older leafless backbulbs can occasionally be potted separately to try to raise a new growth, though this is slower and less reliable than dividing an actively growing clump.
Bloom & Flower Guide
Quick Details
- Bloom Season: Spring and autumn, when days and nights differ most in temperature
- Flower Appearance: Fragrant flowers with elliptic, pointed petals and a tongue-like lip, sometimes waxy or slightly spiralled; colours span purple, brown, red, blue, pink, white, orange, yellow, black or green, often multicoloured
- Edibility: Ornamental — grown for its flowers, not eaten (orchid foliage and flowers are generally non-toxic)
Detailed Blooming Overview
Beallara is a complex intergeneric hybrid in the Oncidium alliance, prized for large, boldly patterned and fragrant flowers. The grower notes petals that are elliptic with a pointed tip and a lip that recalls a tongue, sometimes waxy or a little spiralled, and observes that bloom is brought on by a difference in temperature between day and night — cooler nights and shortening days — with a display that can last up to three months. Flowering falls mainly in spring and autumn.
Flower Characteristics
- Fragrant flowers with five elliptic, pointed petals and a tongue-like lip (grower’s description).
- Petals may be waxy or slightly twisted, in a very wide colour range, frequently multicoloured with stripes, dots or blotches.
- A single flowering can last as long as three months in good conditions.
Bloom Care & Thinning
- Triggering bloom: As the grower advises, a clear day-to-night temperature drop with cooler nights and shorter days brings the plant into flower.
- After flowering: Trim the spent spike to the base once the long-lasting display is over.
- While in spike: Keep light bright but indirect and conditions steady so the buds open cleanly and the fragrance carries.
Bloom Health & Protection
- Botrytis petal blight can spot open flowers with small brown or translucent marks in cool, damp, still air — better ventilation and keeping water off the blooms is the first line of defence, with a fungicide only if it spreads.
- Aphids, scale and mealybugs are drawn to soft buds and flower spikes — wiping them off or treating with neem oil or insecticidal soap keeps the flowers clean.
- Bud blast (buds yellowing and dropping before they open) is usually a stress response to sudden changes in temperature, light or humidity, or to dry air — steady conditions while the plant is in spike prevent it.
Pests, Diseases & Troubleshooting
Overview: This is an intergeneric hybrid in the Oncidium/Odontoglossum alliance, and it shares that group’s well-known pests – scale (especially Boisduval scale), mealybug, spider and false-spider mites, thrips and aphids, plus slugs and snails on new roots and spikes. Its most dangerous problems are rots: black rot (Phytophthora/Pythium) and bacterial soft rot in stagnant, over-wet conditions, and the incurable orchid viruses. Good airflow, careful watering and strict tool hygiene are the foundation of keeping it clean.
Quick Troubleshooting Overview
| Issue / Pest | Main Symptom | Primary Solution |
|---|---|---|
| Boisduval scale | White/pale crusty scale on pseudobulbs and leaf bases, yellowing | Scrub off, horticultural oil, isolate plant |
| Mealybugs | White cottony tufts in sheaths and leaf axils | Alcohol swab, oil/soap, check roots |
| Spider / false-spider mites | Silvery-bronze pitting/stippling on leaves, fine webbing | Raise humidity, wipe leaves, miticidal oil |
| Black rot (killer) | Black, water-soaked spreading rot on leaves/crown | Cut out into clean tissue, cinnamon/copper, dry air |
| Bacterial soft rot | Soft, smelly, collapsing wet leaf lesions | Excise, dry, improve airflow; reduce leaf wetness |
| Pleated / accordion leaves | Permanently folded, ridged new leaves | Correct watering/humidity during growth |
Common Pests & Management
- Boisduval scale (Diaspis boisduvalii):
- Symptoms: The classic orchid scale: crusty white males and round tan-brown female armour clustered on pseudobulbs, leaf bases and under old sheaths and bracts, sucking sap and causing yellow spotting and decline. Populations hide in sheltered crevices and explode if unchecked.
- Prevention & Control: Strip off dead sheaths and bracts where scale hides, scrub visible scale off with a soft toothbrush and soapy water, and isolate the plant. Smother remaining scale with horticultural oil, repeating every 1–2 weeks to catch crawlers; a systemic can help heavy infestations. Inspect new acquisitions carefully.
- Mealybugs (Pseudococcus / Planococcus spp.):
- Symptoms: White, cottony, waxy tufts in leaf axils, inside sheaths, on flower spikes and among the roots, with sticky honeydew and sooty mould; growth stunts and buds abort.
- Prevention & Control: Dab colonies with a cotton bud of rubbing alcohol, hose off, and check the roots and pot rim (repot if root mealybug is present). Follow with horticultural oil or insecticidal soap into every crevice, and repeat; conserve natural enemies where possible.
- Spider mites and false-spider mites (Tetranychus / Brevipalpus spp.):
- Symptoms: Fine silvery-to-bronze stippling or pitting on the (often thin, soft) leaves, with fine webbing from true spider mites; false-spider mites cause sunken, silvery, later necrotic patches. Worst in hot, dry, low-humidity air.
- Prevention & Control: Raise humidity and improve airflow, wipe or hose the leaves (both surfaces), and isolate affected plants. Treat with horticultural oil or a labelled miticide, repeating to break the cycle; these alliance orchids with softer leaves are especially mite-prone.
- Thrips (Frankliniella / Thrips spp.):
- Symptoms: Silvery streaks and flecks on leaves and, most damagingly, distorted, discoloured, streaked flowers with tiny black specks; thrips can also spread viruses.
- Prevention & Control: Use blue sticky traps, remove infested buds and old flowers, and encourage predatory mites. Spinosad or horticultural oil controls outbreaks; rotate products and treat as buds develop.
- Aphids (Aphis / Myzus spp.):
- Symptoms: Green or black aphids on tender new spikes and buds, distorting flowers, leaving honeydew and potentially vectoring viruses.
- Prevention & Control: Rinse off with water, wipe spikes clean, and use insecticidal soap or neem on stubborn colonies; protect developing spikes.
- Slugs and snails:
- Symptoms: Chewed root tips, flower spikes and buds with slime trails; damage appears overnight, and tiny bush snails live in the mix and graze roots.
- Prevention & Control: Hand-pick at night, set beer or iron-phosphate traps, keep the bench clean, and repot if the mix is infested with bush snails; inspect new plants and mix.
Diseases & Fungal Issues
- Black rot (Phytophthora / Pythium spp.):
- Symptoms: Black, water-soaked, rapidly spreading rot on leaves, new growths and the crown, often starting at the base and killing the plant fast in warm, wet, stagnant conditions.
- Treatment & Management: Cut out all blackened tissue well into clean green tissue with a sterile blade, dust the wound with cinnamon or a copper fungicide, and move the plant to dry, airy conditions with reduced watering. Improve airflow and never let water sit in the crown.
- Bacterial brown spot / soft rot (Acidovorax / Erwinia (Pectobacterium)):
- Symptoms: Soft, water-soaked, sunken lesions that turn brown-black, smell foul and collapse, spreading quickly on wet leaves in warm humid air.
- Treatment & Management: Excise the infected area into healthy tissue with a sterile tool, keep the foliage dry, and increase airflow. Reduce humidity around the plant and avoid overhead watering; copper can protect surrounding tissue.
- Botrytis flower spot (Botrytis cinerea):
- Symptoms: Small brown or pinkish spots peppering the flowers, which age and rot prematurely in cool, damp, still air.
- Treatment & Management: Remove spotted blooms promptly, improve air movement, and lower humidity around flowering plants; avoid misting open flowers.
- Fungal leaf spots (Cercospora / Guignardia spp.):
- Symptoms: Yellow then brown-black spots and blotches on the leaves, sometimes in rings, in humid, crowded, poorly ventilated conditions.
- Treatment & Management: Remove affected leaves, improve spacing and airflow, and keep foliage dry. A copper or labelled fungicide checks persistent spotting.
- Orchid viruses (CymMV & ORSV):
- Symptoms: Colour-break, streaking, ringspots, mosaic mottling and necrotic flecks on leaves and distorted, blotchy flowers; permanent and incurable, spread by cutting tools and sap-sucking pests.
- Treatment & Management: There is no cure – isolate and ideally destroy confirmed virus plants. Prevent spread by sterilising cutting tools between every plant (flame or fresh blade), controlling sap-sucking pests, and buying clean stock.
Growing Difficulties & Abiotic Problems
- Root loss from over- or under-watering:
- Cause & Symptoms: These alliance orchids resent both soggy, stale mix (which rots the fine roots) and complete drying; either causes root loss, then dehydration and decline.
- Correction Strategy: Water thoroughly then let the mix approach (not reach) dryness, use a fresh open medium, repot every 1–2 years, and ensure the pot drains freely with good air to the roots.
- Pleated / accordion leaves:
- Cause & Symptoms: New leaves emerge permanently folded and ridged when the plant is under-watered, under-humidified or root-damaged during the growth flush.
- Correction Strategy: Keep humidity up and moisture even while new growths expand, and fix any root problem; the pleating is permanent on affected leaves but future growth will be smooth.
- Leaf-tip dieback (salt / fertiliser burn):
- Cause & Symptoms: Blackened, dying leaf tips from accumulated salts, over-fertilising, or hard water.
- Correction Strategy: Flush the mix periodically with plain water, feed ‘weakly, weekly’ at reduced strength, and use rain or low-salt water where possible.
- Sunburn:
- Cause & Symptoms: Bleached white-to-brown scorched patches on leaves exposed to too-intense direct sun – these are moderate-light, cool-to-intermediate orchids.
- Correction Strategy: Provide bright, filtered light; shade from midday sun and acclimatise gradually when moving plants to brighter conditions.
- Poor or no blooming:
- Cause & Symptoms: Failure to spike usually reflects too little light, insufficient day-night temperature difference, or a stressed root system.
- Correction Strategy: Increase light to the recommended level, allow a cooler night drop, keep roots healthy, and feed appropriately through the growing season.
What Helps – Products & Tools
Prevention is cultural – airflow, careful watering, clean benches, quarantine of new plants and, above all, sterilising cutting tools between plants to stop virus spread. Useful products include horticultural oil and insecticidal soap (scale, mealybug, mites, aphids), blue sticky traps and spinosad (thrips), iron-phosphate slug bait, copper fungicide and cinnamon for rots and leaf spots, and a low-salt orchid fertiliser. Apply oils in the evening and never on open flowers.
