Why is my king palm losing its dark green colour

Featured Replies

I’m a little bit concerned due to the fact that my king palm is slowly turning lime green and losing colour even though I’m fertilising it it’s out in the sun but I don’t think that’s the main issue this is what it looked before and this is after

A bit of mild sun burn . Typical with recently planted palms in full sun . It may take a while for it to settle in . Remember these like room for their roots and plenty of water. If it is still in a nursery pot , the black pot could be overheating the root ball. If it is in the ground , it will take time to settle in. I don’t fertilize my Archontophoenix here just copious amounts of water , especially in summer. It would depend on your soil there as to what to feed it , if anything. I had a yellowing King at my old house and I gave it SulPoMag (Sulpher , Potassium and Magnesium) . In a couple of months the new fronds were a darker green . A year later it looked fantastic.

Once your palm gets going in the ground …..LOOKOUT! They grow fairly fast and that trunk will push it up towards the sky. That one is at that acceleration stage. Harry

Archontophoenix cunninghamiana normally spread their roots far and wide. They can travel 30 feet (over 9 meters) horizontally from the base of the trunk. Yours is already pushing itself out of the small pot. A healthy one will have 8 to 12 inches (about 25 cm) between trunk leaf scars. Your palm’s are much closer together indicating not optimum growing conditions. These palms need constantly wet soil. I’d suggest getting yours in the ground or, at the very least in a bigger and deeper pot.

These are in full sun but deep green due to good soil, occasional feeding, and lots of water.
