About Alexandra Palm
Archontophoenix alexandrae · also called Alexandra palm, northern bangalow palm · tropical
The Alexandra palm is a fast, elegant feather palm from tropical Queensland rainforests, building a slender ringed trunk topped by an arching crown and a prominent green crownshaft. Grown outdoors in frost-free climates or as a young container specimen, it wants warmth, steady moisture, rich free-draining soil and bright light to thrive.
Ideal humidity: 50-70%
Watch for — Brown frond tips: Low humidity, dry air or underwatering. Raise humidity and keep the rootball evenly moist.
The watering schedule, season by season
Alexandra Palm wants steady, even moisture — it resents both a bone-dry rootball and a swampy pot, and is sensitive to salt build-up. The base rhythm for alexandra palm is keep evenly moist; water when the top 2-3 cm of soil is dry, roughly every 4-7 days in growth, but the real interval moves with the season, the light and the pot — so treat the figures below as a starting point and always confirm with the plant itself.
- Spring & summer (active growth): Spring and summer: keep evenly moist, watering when the top 2-3 cm is dry — typically every 4-7 days.
- Autumn (slowing down): Autumn: let the top third dry between waterings as growth slows.
- Winter (rest / dormancy): Winter: water less and check deeper before pouring; cold wet roots invite rot.
A thirsty rainforest palm that hates drying out fully but also resents waterlogging. Water deeply, let the surface barely dry, and reduce in cool months. Brown frond tips often signal underwatering or dry air.

How to tell alexandra palm needs water
A calendar is the worst way to water alexandra palm. Check the plant and the soil instead — for this species, look for these signals in order:
- The top 2-3 cm of soil is dry to the touch.
- Fronds lose a little of their arch or sheen.
- The pot feels lighter than just after watering.
The most reliable single check is the first one on that list. When two signals agree, water; when they disagree, wait a day and look again — under-watering alexandra palm for a day is almost always safer than over-watering it.
Overwatering vs underwatering alexandra palm
The two failure modes can look alike at a glance, so check the soil weight and wetness before you decide. For alexandra palm specifically:
Signs you are overwatering
- Yellowing fronds with a constantly wet, heavy pot.
- Mushy base and a sour soil smell.
- Lower fronds collapsing in numbers.
Signs you are underwatering
- Crispy brown frond tips and edges (also worsened by salty tap water).
- Whole lower fronds going crispy and dry.
Both extremes punish alexandra palm: a dried-out rootball browns the frond tips permanently, while a constantly wet pot rots the roots. Aim for the steady middle.
Water quality notes
Palms are salt-sensitive — use filtered or rainwater if your tap water is hard, and flush the pot occasionally to leach out mineral build-up that browns frond tips.
Seasonal and environmental adjusters
Every figure above shifts with the conditions in your home. For alexandra palm, the levers that matter most are:
- Higher humidity slows drying and reduces frond-tip browning.
- A larger pot of mix holds moisture longer — adjust the interval to the pot, not the calendar.
- Flush thoroughly every month or two to wash out accumulated salts.
Pot choice is part of this too — work out the right size with the pot size calculator, since a pot that is too big stays wet long enough to rot the roots of alexandra palm.
