I actually have 2 problem plants
1. In my front yard I transplanted 2 healthy pigmy date palms from a friend's yard to mine. One is doing fine, the other is clearly dying. For 2-3 months it was doing ok, but the last month the fronds all started wilting, then the lower ones started turning brown, then the center ones started turning light green. I give the plant a good watering every 2 days, he gets 4-5 hours of full sun a day, I live in souther california and plenty of neighbors have the same plants that are doing fine. I just got a moisture meter to I can monitor soil moisture. Im 90% certain my soil is bad. I did a jar test and it looks like its >80% sand based on how much settles instantly, but the strange thing is below the plants, the soil gets rock hard and water puddles on top of it for 5min or so before soaking in (kinda like clay) so I guess I have no clue what kind of soil it is. Can anyone confirm what the problem could be? Does it look like a lack of nutrients or drainage? Should I get palm fertilizer or does it look pretty much dead? Picture below
2. In the back yard, there are 3 healthy looking pigmy palms that have been there since I moved in, but the last few months it looks like the new fronds that are growing in the center are covered with a layer of white gunk. Tried to take a picture below. Any idea what this is and how to get rid of?
