I recently re-landscaped by newly built house and it looks fantastic. The landscape features a mule palm, sylvester palm, mammey crotons, variegated ginger, scranton bamboo, and black lake bamboo.
My neighbors had some mammey crotons going into the winter last year and lost them in a relatively (for zone 9B) harsh frost. What is the best and easiest way to combat frost damage on cold nights? I've thought about frost blankets but worry about needing to put them out on the cold nights. I've also thought about laying heat cable like this https://www.lowes.com/pd/EasyHeat-ADKS-100-ft-500-Watt-Roof-Heat-Cable/3115537 on top of the mulch 1-2ft from each plant. I could then set a smart outlet to turn it on when the forecasted low is below 40F.
Any thoughts? My goal here is fool proof, easy frost protection… not necessarily what would be the cheapest solution (probably frost blankets).
