request help with struggling Areca palm

[Jupiter]

Hello, I was hoping that the experts here could help me out with my first palm tree, an Areca.

I've had a lot of leaves start browning and the pattern does not match any images I can find online for typical Palm diseases.

I've been careful about giving it sufficient but not too much sunlight and making sure it's dried out before watering. I use a fish emulsion fertilizer and I've sprayed it with insecticidal soap and rubbing alcohol.

I haven't noticed any mold or scale. There is something like brown dust on some of the stalks and these small things on the undersides of some leaves that are like half cm pieces of string.

Thank you very much! I would love to rescue it.

It may just be too dry. Also, the alcohol wipe may be toxic.

Welcome to the forum! I am most certainly not an expert but I did have a potted areca (Chrysalidocarpus lutescens) for a couple years. It sounds like you have already considered the plant's environmental needs but it's always good to confirm it's not located near a vent, not left to dry too much between watering, etc.

Rubbing alcohol will cause a lot of damage, fast. I use a foliar spray (malathion) and a systemic (imidacloprid.) Together they are very effective but the warning labels are scary. If that brown dust is a group of spider mites you should check your insecticide label to see whether it controls them. You might need a miticide. Since there aren't many leaves you could also try wiping clean on both sides with a damp paper towel.

What state are you located in? Looks like your palm - Chrysaladocarpus lutescens/golden cane palm? - is stuck inside a dark, dry, possibly cold northern house. If you live in a cold northern climate you may need to provide supplemental light, heat and humidity to keep it alive through the coming winter. If you live in FL you may be able to place it outdoors except on the coldest nights. Most palms are ambivalent about pot culture; some tolerate a pot, others hate pots. Palms would much rather be in the ground than a pot. Be sure to use a coarse, loose potting mix; no black houseplant soil. Do not overwater or you risk root rot. Don't fertilize during winter.

It seems that your areca palm has scale insects or mealybugs—they leave brown dust and fibrous deposits. Isolate the plant, gently wipe the leaves with soapy water or alcohol, and treat with a systemic insecticide if necessary. Make sure there is no excess fertilizer or moisture.

No alcohol, no detergents. Buy a bar of Ivory SOAP and fill a bucket with fresh water. Shave slivers of soap into the water and mix into a soap solution. Dip a soft cloth, preferably cotton into the soapy water then gently sponge the palm from tips to base, including petioles, leaf undersides, crown. Wait a few days then gently rinse away soap solution. A couple days later inspect palm for signs of vermin. If so, treat with more insecticidal soap.

Palms can be good house plants but need attention . Depending on where you live , it could be not enough humidity , too much or not enough water and sunlight , or a combination of these. When I had my C. Lutescens in my old house , I would put it outside in the shade of our porch and rinse it down and allow the palm to have fresh air for a few days before bringing it back inside. When we moved to our new house , I planted it in the garden . It was an indoor palm for about 4-5 years and grew OK but once it hit the dirt , it took off . It would be hard to determine exactly what your palm needs , the pictures don’t necessarily indicate an infestation . Most common infestations are Mealy bugs ( small white powdery looking bugs) or Scale ( sticky bumps on the undersides of the leaves or stems ) . My first hunch would be lack of humidity or poor soil condition. Harry
