Cloud Cover or similar to prevent leaf burn?
We are *finally* getting around to constructing our Japanese garden, and now I have to deal with where exactly my little Sango kaku will go. I have an almost perfect spot -- it is protected from winter winds (it is not cold here but gets QUITE windy in the winter); also protected from strong, hot summer winds, receives morning and early afternoon light. Here's the catch: most of the year it will be protected from hot afternoon light, but for about a month in the summer it will be exposed to strong afternoon light. (I know; that's exactly the wrong time of year for that, but I am limited in where exactly I can place my little tree.)
My question: Is there anything I can spray on the leaves to help it through that one month? It has had very nice color this year but now the leaf edges are getting that crispy look. I have been hearing about an anti-transpirant called Cloud Cover -- will it help protect from strong sun? Will anything else? I could put up shadecloth of some sort but it would really ruin the looks of the rest of the garden.
Any help much appreciated!
