Sentry Palm also called Curly Palm is a slow growing Indoor Palm with soft, drooping leaflets which is ideal for adding an exotic feel in any space. It is endemic to Lord Howe Island, Australia. The palm grows to a height of 3-4 ft under good indoor growing conditions. Sentry Plam belongs to a group of palms (called feather palms) which produce fronds which are divided on either side of the midrib into leaflets. Curly Palm has a thin, slender trunk with feather-shaped drooping fronds which produce wide leaflets. The trunk is dark-green when young and turns brown as it ages. The canopy of a mature palm can spread 5-10 ft in diameter. This palm's fronds are more drooping and is generally smaller than its close relative Howea forsteriana (Kentia Palm) which grows to a height of 8 ft.
Sentry Palm prefers bright, indirect light but it can tolerate some shade. Too much light will cause the palm to develop a yellowish color. Learn how to ensure your plant receives the correct light in this guide on understanding light for houseplants.
Keep the soil moderately moist at all times for Sentry Palm during the growing season. Reduce watering in the cold season and allow the soil to dry out between waterings. Use chlorine-free water for watering; like all palms Sentry Palm, is sensitive to chlorine and other chemicsl dissolved in water. Avoid getting the base of the palm wet to prevent rotting. Do not allow the palm to sit in soggy soil as it may lead to root-rot and eventual death of the palm. Learn more on how to water houseplants.
Average warmth with a minimum of 100C is ideal for Sentry Palm. If the temperature is comfortable for you it is suitable for the Sentry Palm. Protect the palm from cold draughts. Find out more on temperature for houseplants.
Sentry Palm requires a humid environment. Mist the leaves regularly or set the pot on a wet pebble tray to raise humidity in order to keep the fronds looking green and healthy. Occasionally clean the mature leaves by damp-wiping with a soft cloth to get rid of dust.
Feed Sentry Palm with a water-soluble fertilizer monthly during the growing period. Water thoroughly until the solution comes out through the drainage holes. Withhold feeding in the cold season as growth is minimal at this time. Find out more on feeding houseplants.
Avoid repotting Sentry Palm too frequently as is sensitive to root disturbance. Pot only when the palm is extremely root-bound and take care to not to damage the roots. Sentry Palm is highly adaptable to a variety of soil but it prefers sandy, free-draining potting soil.
Pruning Sentry Plam is easy. Cut away the old brown and dry fronds near the soil surface to maintain your plant neat and tidy. Cut away any flower stalk immediately to prevent the plant from wasting energy on developing the flowers. Learn more on how to prune houseplants.
Sentry Palm can be propagated from seeds but this is difficult and the palm rarely produces seeds when grown indoors. It is advisable to buy a new plant from the breeders.
Reasons for brown leaf tips in Sentry Palm are dry air, underwatering, cold draughts and damage by touching. Trim off the brown tips with sterilized scissors. Correct the faults by raising the humidity, watering correctly, protecting the plant from draughts and placing the palm away from traffic respectively.
Underwatering is the reason for yellow leaves in Sentry Palm. Keep the soil moderately moist at all times during the growing season. Do not allow the soil to dry out completely. Learn more on how to water houseplants.
Overwatering or sudden decrease of temperature are the causes of brown spots in Sentry Palm. Remove the affected parts and improve the growing conditions by correct watering and maintaining the right temperature by protecting Sentry palm from cold draughts.
The lower leaves of Sentry Palm may turn brown and droop due to age; remove by cutting and not pulling. If browning is general and accompanied by rotting the reason is root-rot disease due to waterlogging.
Underwatering is the cause of drooping leaves and stems in Sentry Palm. Keep the soil slightly moist at all times and never allow the soil to dry out completely. Learn more on how to water houseplants.
