🪴 Handling and Caring for Tolumnia Jairak Firm ‘Crimson’
1. Light ☀️
-
Prefers bright, indirect light (similar to Cattleya orchids).
-
Tolerates some direct morning sun, but avoid harsh midday sun.
-
Insufficient light = no blooms.
2. Temperature 🌡️
-
Intermediate to warm: 20-30°C (68-85°F).
-
Avoid temperatures below 15°C (59°F).
3. Humidity 💧
-
Loves high humidity (50-70%).
-
Use humidity trays or a humidifier in dry environments.
-
Ensure good air circulation to prevent fungal problems.
4. Watering 🚿
-
Unlike most orchids, Tolumnias prefer to dry quickly between waterings.
-
Water 2-3 times a week during active growth.
-
In cooler or dormant periods, reduce to once a week.
-
Mounted plants dry faster and may need more frequent watering.
5. Potting & Medium 🪵
-
Often grown mounted on wood/slabs or in small baskets.
-
Use coarse bark, charcoal, or sphagnum moss sparingly.
-
Ensure excellent drainage—Tolumnia hates soggy roots.
6. Fertilizing 🌿
-
Feed with a balanced orchid fertilizer (20-20-20) at 1/4 to 1/2 strength.
-
Fertilize every 2 weeks during active growth.
-
Flush with plain water once a month to avoid salt buildup.
7. Repotting 🪴
-
Repot every 1-2 years or when the medium breaks down.
-
Best time to repot is after flowering.
8. Pests/Diseases 🐛
-
Watch for scale, mealybugs, and spider mites.
-
Good airflow and proper watering prevent most problems.
