Phalaenopsis schilleriana plant care +Best 10 Step-by-Step Guide

Phalaenopsis schilleriana plant care +Best 10 Step-by-Step Guide

Phalaenopsis schilleriana, native to the Philippines, produces abundant rose-pink flowers with white or yellow spotted red-purple lips, measuring over 2 inches wide, arranged in lengthy, branching racemes that can reach up to 3 feet in length, typically appearing in winter and spring. This epiphytic orchid earns its name from its moth-like blossoms. Suited more for experienced gardeners, it demands warmer and more consistent growing conditions compared to other varieties. Its elliptical, dark green leaves emerge from short, thick, upward-growing rhizomes, occasionally displaying speckles or mottles depending on the species.

The long-lasting flowers develop at the base of the leaves, forming simple or branched racemes. Orchids bloom sporadically and, under favorable conditions, may flower up to three times annually. To thrive, provide ample light and maintain a consistently humid environment, occasionally misting the leaves. Water generously from spring through fall and fertilize monthly using a balanced fertilizer. Traditionally, orchids are cultivated in a loose bark mix. Trim back spent racemes once flowering has concluded.

For Phalaenopsis schilleriana, provide bright, indirect light. This means placing it near a window where it receives plenty of light but is shielded from direct sunlight, especially during the hottest parts of the day. If the leaves are dark green, they might need more light, whereas if they’re pale green or yellowish, they might be getting too much light. Adjust as necessary to guarantee ideal development and well-being.


Maintain temperatures between 65 and 80°F (18 and 27°C) during the day for your Phalaenopsis schilleriana orchid. It can handle significantly colder temperatures at night. Avoid exposing it to extreme temperature fluctuations or drafts, as this can stress the plant. Keeping a consistent temperature within this range will help promote healthy growth and flowering.


Maintain high humidity levels for your Phalaenopsis schilleriana orchid, ideally between 50 and 70%. You can achieve this by using a humidifier, grouping plants together to create a microclimate, or placing a tray of water with pebbles beneath the orchid pot. Regular misting can also help increase humidity, but avoid misting directly onto the flowers, as this can cause damage. Consistent humidity levels are crucial for preventing issues like dehydration and bud blasts.


Water your Phalaenopsis schilleriana orchid thoroughly when the potting mix feels dry to the touch, typically every 7–10 days. Use room-temperature water and allow excess water to drain out completely. The orchid’s roots may decay if it is left to stand in standing water.
Adjust your watering frequency based on environmental factors such as temperature, humidity, and the type of potting mix used. It’s better to do it underwater than overwater, as orchids are susceptible to root rot caused by soggy conditions.

Potting Mix:

For your Phalaenopsis schilleriana orchid, use a well-draining orchid mix such as bark or sphagnum moss. These mixes provide good aeration and drainage, which are essential for orchid roots. When repotting, ensure the new potting mix is fresh and free from any signs of decay or pests. Repot the orchid every 1-2 years, or when the potting medium breaks down, to provide fresh nutrients and prevent root suffocation. Choose a pot with ample drainage holes to prevent waterlogging.


Air Circulation

Ensure good air circulation around your Phalaenopsis schilleriana orchid to prevent the buildup of stagnant air, which can lead to fungal issues and other problems. You can achieve this by placing the orchid in a room with adequate airflow, using a fan to gently circulate air around the plant, or opening windows periodically to allow fresh air to enter the space. Avoid placing the orchid in areas with drafts or strong winds, as this can cause stress to the plant. Regular air circulation helps promote healthy growth and prevents the development of pests and diseases.


Pruning your Phalaenopsis schilleriana orchid is essential for maintaining its health and appearance. Here’s how to do it effectively:

Remove spent flower spikes: After your orchid has finished blooming, cut back the flower spike to just above a node (a small bump on the spike). This encourages the plant to redirect energy into new growth rather than producing seeds.

Trim dead or yellowing leaves: Use clean, sharp scissors or pruning shears to remove any dead, yellowing, or damaged leaves. Cut them off at the base of the leaf, where it meets the stem.

Remove old pseudobulbs: If your orchid has old, shrivelled pseudobulbs (thickened stems used for storing water and nutrients), you can carefully trim them away to promote new growth. Use sterilised instruments to stop the transmission of illness.

Prune aerial roots: If your orchid has long, unruly aerial roots, you can trim them back to a more manageable length. However, be careful not to remove too many roots, as they play a crucial role in nutrient absorption and anchoring the plant.

Disinfect your tools: Before and after pruning, disinfect your scissors or pruning shears with rubbing alcohol or a diluted bleach solution to prevent the spread of disease between plants.

By regularly pruning your Phalaenopsis schilleriana orchid, you can promote new growth, improve air circulation, and maintain a tidy appearance.

Pest and Disease Control:

To keep your Phalaenopsis schilleriana orchid healthy, it’s essential to watch for common pests and diseases and take prompt action if you notice any signs of trouble. Here’s how to control pests and diseases effectively:

Inspect regularly: Check your orchid regularly for signs of pests such as aphids, mealybugs, scale insects, spider mites, and thrips. Look for any unusual discoloration, spots, or wilting that could indicate the presence of disease.

Isolate infected plants: If you discover any pests or diseases, isolate the infected orchid to prevent the problem from spreading to other plants in your collection.

Remove pests manually: For minor infestations, you can often remove pests by gently wiping them off the leaves and stems with a soft cloth or cotton swab dipped in alcohol. Be sure to check both sides of the leaves and the crevices where pests like to hide.

Use insecticidal soap or neem oil. For more significant pest infestations, you can treat your orchid with insecticidal soap or neem oil. Follow the manufacturer’s instructions carefully, and avoid spraying the flowers directly to prevent damage.

    Prune affected areas: If your orchid is affected by fungal or bacterial diseases, such as root rot or leaf spot, prune away affected areas using sterile tools to prevent the spread of infection. Between cuts, make sure to sanitise your instruments.

Improve growing conditions: Maintain optimal growing conditions for your orchid, including proper watering, humidity, and air circulation. Pests and diseases are more difficult for healthy plants to withstand.

Consider systemic treatments. In severe cases, you may need to use systemic insecticides or fungicides.

 which are absorbed by the plant and provide long-lasting protection. However, use these products with caution and follow the instructions carefully to avoid harming your orchid or yourself.

By staying vigilant and taking proactive measures to control pests and diseases, you can keep your Phalaenopsis schilleriana orchid thriving and beautiful.

Rest Period:

Phalaenopsis schilleriana orchids may go through a rest period after flowering. During this time, typically in the winter months, you can adjust your care routine to accommodate their natural cycle:

Reduce watering: Scale back on watering slightly during the rest period. Allow the potting mix to dry out a bit more between waterings, but still ensure the orchid doesn’t become completely dry.

Limit fertilisation: cut back on fertilising during the rest period or stop altogether. Phalaenopsis orchids generally require less fertiliser when they are not actively growing and flowering.

Provide slightly cooler temperatures: While Phalaenopsis orchids prefer warm temperatures, you can slightly lower the temperature during the rest period, aiming for the lower end of their preferred range.

Maintain humidity: Continue to provide high humidity levels for your orchid, as this is important for overall health and vigour.

Monitor growth: During the rest period, you may notice reduced growth and flowering activity, which is normal. Keep an eye on your orchid for any signs of stress or disease, and adjust your care routine as needed.

By allowing your Phalaenopsis schilleriana orchid to rest during the winter months, you can help ensure it remains healthy and ready to bloom again in the spring.
