My rose plant was looking healthy and promising with many rose buds. A couple days later the leaves are full of holes and also ragged edges. It seems the answer is: tiny green worms ... chomping away... I found and picked off maybe six of them. Please shed light as to where originate from? Is the plant in a weakened susceptible condition so it gets attacked? and any suggestions on how I can treat to get rid of the worms and retrieve plant ?...(I tried a couple possible home remedies....but I was only guessing. and this was just yesterday ...so I don't know if it helped.
