Resin eating my yucca plant leaves??
Hi, some of the leaves on my yucca plant are being consumed by something unknown - but it leaves behind a red "resin" which turns into a solid amber-like substance. The leaves are slowly dying off but I have no idea how / why / what it causing it! Please see the images attached which should be useful. Thanks for your help! Joel
