How to soak a palm sapling properly
Time it correctly: Three hours is a safe duration for soaking a rooted sapling. Soaking for too long (over 8–24 hours) can deprive the roots of oxygen, potentially killing the plant.
Keep the roots moist, not saturated: Ensure that the roots are kept moist during storage. While soaking for a few hours is acceptable, leaving the roots submerged for extended periods can cause them to drown.
Use the right water: Use room-temperature tap water. Some gardeners even recommend adding a small amount of liquid fertilizer to the water to help with the transition.
Avoid sunlight: Keep the sapling out of direct sunlight while it is soaking.
