Size Options

50mm Pot

Supplied as one young, established mericlone in a 50mm nursery pot.

Plants supplied in 50mm pots are not flowering size and require further time to grow and develop. Plant size, leaf number and root development will vary naturally.

100mm Pot – Flowering Size, Bare-Rooted

Where available, the 100mm option is a larger, more developed flowering-size plant. It is suitable for customers wanting a more advanced orchid without the additional growing time required by the younger 50mm option.

The plant is grown in a 100mm nursery pot and supplied bare-rooted, with the original pot and growing medium removed before dispatch. The 100mm measurement refers to the nursery pot in which the plant was grown—not its overall height or width.

Plant size, pseudobulb number, leaf growth and root development will vary naturally.

Potting the Bare-Root 100mm Plant

Unpack the bare-root plant promptly after delivery and pot it into a clean, appropriately sized orchid pot.

Use a medium-grade, free-draining Cattleya orchid mix. Position the oldest growth towards the edge of the pot, leaving room for new growth to develop across the remaining space.

Keep the rhizome and bases of the pseudobulbs at or slightly above the surface of the growing medium. Do not bury them deeply.

Secure the plant firmly so it does not move while new roots establish. Water after potting and allow the container to drain completely.

Care Instructions

Light

Grow Rlc. Subprasert ‘No. 1’ in bright, filtered light.

Cattleyas generally require more light than many common indoor orchids, but they should be protected from harsh direct afternoon sun.

Suitable positions include:

• A bright window with filtered light
• A covered patio or verandah
• A well-ventilated shade house
• A suitably shaded greenhouse
• A protected outdoor position in a frost-free climate

Healthy foliage is generally medium green. Very dark green foliage may indicate insufficient light, while yellowing, bleaching or scorched patches may indicate excessive direct sun.

Watering

Water thoroughly and allow the orchid mix to approach dryness before watering again.

This orchid prefers a wet-and-dry watering cycle and should not remain constantly wet. Empty saucers and decorative pots after watering so the roots are not left sitting in water.

Watering frequency will depend on:

• Plant and pot size
• Temperature
• Season
• Humidity
• Air circulation
• Type of orchid mix

Young plants in 50mm pots can dry more quickly than larger orchids. Check the growing medium regularly during warm or windy weather.

Reduce watering during cooler periods when active growth slows, but do not allow the pseudobulbs to become severely shrivelled.

Humidity and Airflow

Provide moderate to high humidity combined with good air circulation.

Avoid stagnant or continually damp conditions, particularly during cooler weather. Air movement helps the leaves and roots dry properly after watering.

Potting Mix

Use a free-draining orchid medium that allows plenty of air to circulate around the roots.

A fine-to-medium orchid bark mix is generally suitable for a young 50mm plant. A medium-grade Cattleya mix may be used for a larger 100mm plant.

The ideal grade will depend on your climate and watering habits. Avoid ordinary garden soil or dense potting mixes that remain wet for extended periods.

Temperature and Climate

Rlc. Subprasert ‘No. 1’ prefers warm, protected and frost-free conditions.

It is well suited to tropical and subtropical climates when grown under filtered light with good airflow. In warm-temperate climates, protect the plant from frost and cold winter weather.

In cooler regions, grow it indoors beside a bright window or provide protection in a greenhouse or enclosed orchid-growing area.

Protect the plant from:

• Frost
• Cold draughts
• Extreme heat
• Harsh exposed positions
• Sudden temperature changes

Feeding

Apply a suitable orchid fertiliser at a light rate during active root, leaf and pseudobulb growth.

Follow the fertiliser label directions and avoid applying concentrated fertiliser to dry or damaged roots. Reduce feeding during cooler periods or whenever active growth slows.

Repotting

Repot when the orchid has outgrown its container or when the growing medium begins to break down.

The best time to repot is generally when fresh roots are beginning to emerge. Choose a pot that provides enough room for the next few growths without leaving excessive wet growing medium around the roots.

Cattleyas generally perform best when fitted reasonably snugly into their pots.

Mounting

Rlc. Subprasert ‘No. 1’ may also be grown on cork bark, hardwood or another suitable orchid mount.

Mounted plants dry more quickly and require more frequent watering. This method is best suited to growers who can provide regular moisture, suitable humidity and good airflow.

FAQ

What colour are Rlc. Subprasert ‘No. 1’ flowers?

The flowers are deep raspberry red to magenta with a darker maroon-red lip. The throat features glowing red-orange colouring and fine golden-yellow lines.

What is the parentage of Rlc. Subprasert?

Rlc. Subprasert was produced from Rlc. Sanyung Ruby × Rlc. Boonyarit Sunset.

What sizes are available?

Available sizes are shown in the product selector. Options may include a young plant in a 50mm pot and a larger flowering-size plant grown in a 100mm pot.

What is the difference between the 50mm and 100mm options?

The 50mm option is a young plant that requires further time to grow and develop. The 100mm option is a larger, more developed flowering-size plant.

How are the plants supplied?

The 50mm option is supplied in its nursery pot. Where available, the 100mm flowering-size option is removed from its nursery pot and supplied bare-rooted.

What does mericlone mean?

A mericlone is propagated from selected plant material rather than grown from seed. This provides greater consistency in growth and mature flower characteristics, although minor natural variation can still occur.

Can this orchid be grown indoors?

Yes, provided it receives plenty of bright, filtered light and good airflow. A dim indoor position is unlikely to provide suitable long-term growing conditions.

What potting mix should I use?

Use a free-draining orchid bark mix that allows air to circulate around the roots. Avoid ordinary garden soil and dense potting media that remain wet.
