We have a foxtail that was growing beautiful until 12mths ago. It just stopped shooting new fronds. We read to give it an application of potash but 3 mths later still no signs of any new fronds. The trunk stands about 3mtrs tall and has 4 fronds which have been there, for 12mths. We thought it was dying as the fronds are very droopy hanging but they are all still green. Can you give me any advice why our foxtail hasn't shot any new fronds for over 12mths?
This can have a few causes. If there has been a little cooler than normal lately, then this could be the reason. If this is not the case, Then I would apply a fertilizer meant for palms. A google search will take you to many options.
