The windmill palm is around 15 yo, rather tall, It's been moved a year ago and last winter we had frost in UK. Some roots broken/damaged during the excavation from previous owners. Tree was OK and green for a few months. No fruits this year. New spears are sturdy but yellowy with no development. Looks like the palm stopped from growing and slowly dying. Most fronds bent half way, yellowy and dried towards the end.

Watering on a regular basis since I got it last summer and using Palm focus as fertilizer since the issue.

Any advice would be greatly appreciated, thanks.

The planting looks a little unusual surrounded by pavers. Tell us about soil conditions, fertilizer, watering and how it was planted. It usually takes 2 years to recover from moving

Do the new fronds look good? I'm with Allen, still recovering from transplantation is my guess.

It can take even longer especially in a cool climate with a short growing season. The larger the palm the longer the recovery. It all depends on how much of a root ball you got. I really don’t think there is much to do here other than keep up with the regular watering and wait. If you see some funkiness in the crown and with the newer spears treat it with copper fungicide. Don’t trim any fronds no matter how unsightly unless they are 100% brown.
