There’s no magic potion to increase survival of frost-intolerant, heat-loving plants. Instead, be patient and know how to recognize signs of survival. Several weeks ago I recommended patience and leaving certain plants alone until at least May 1. This included palms and sagos as well as heat-loving plants like esperanza, firebush and Pride of Barbados.
Initially I estimated 90& of Mexican fan palms and 70% of sago palms would die, but it now appears that many Mexican fan palms and sagos survived — more than 50% of them, to be exact. And that’s great news! Patience does pay off.
Unfortunately, there’s not much you can do to increase survival of frost intolerant, heat loving plants. Nor are there concoctions, powders or spells you can apply. You must have patience and wait. Then, know what to look for.
When a palm shows green at the very top or green sprouts at the base in the woody plants, provide a moderate amount of water on a regular basis and a small amount of organic fertilizer that incorporates micro-nutrients like iron, manganese and magnesium.
Be careful not to overwater. The quickest way to kill palms and other heat tolerant woody perennials is by giving them too much water.
Eventually your palms will return to full beauty. It may take about six to eight months, but have patience and they’ll likely rebound.
