I have Sykes Dwarf and one called perhaps Snow queen? Since they are both babies, they are about the same size. My uncle just sets the asphalt here and there, actually he puts it on a big weed, it does deterioate when exposed to sun and rain and crumbles. He may be crazy, it may not be good for plants, but he is usually right.
I am spraying my rhodendrons. I was supposed to start in June but we had the weather, anyway, today is the day. I have to saturate the soil around the stem and then soak each leaf and this stuff really stinks. And I have a lot of rhodys, I spent 2 hours and am about 1/4 done and still have the ones in the ground. We get nasty weevils that eat the leaves and the larvea eat the roots and kill the plant. I have to spray 3 times, 10 days apart then I am done unless I see damage, then once again.
