Japonicas may suffer if they get too much sun (Sasanquas can handle more sun). Wind can also cause drooping when the leaves loose moisture faster than the plant can absorb moisture through the roots. Protection from the winds can help remedy the dropping problem. Protection from too much sun can help remedy the browning of leaves. Maintaining the soil evenly moist can help a little with both issues. Aim for 4 hours of sun or less. Summer temperatures, summer winds and lack of Spring-like moisture plus transplant shock (an affected root system) are making the shrubs react this way. In Z10, I would have transplanted them during the winter months but I understand that this is something one cannot schedule sometimes. If they get a lot more than 4 hours of sun, you may need to transplant them again. Temporarily, you can help[ by keeping the soil moist as evenly as possible; block the sun with 35% shade cloth or some other object; protect from the winds with some object. And mulch, mulch, mulch. About 3-4" of mulch. Because the area is windy, I would also maintain about 6" of mulch past the drip line. Stressed plant should not be fertilized so I would not fertilize until next year. It would be ok to amend however, if you have to tweak the soil pH, etc. Make sure the plant remains about 1" higher than the surrounding soil. You may also want to use a stake in case there are sudden strong winds.

For small peonies, I use the top ring of tomato cages, cutting just above the next ring down. Then I use the lower part to put around another perennial. Check out your local "Dollar Tree' or equivalent store. I have lucked out and found them there instead of paying high prices at nurseries.

A local garden club sells a set of 3 nesting cages for $37 (with 2 rebar each for anchoring), or one for $15, at their huge annual tomato-seedling sale -- too much for me, but they seem to be popular. http://mastergardeners.org/SGM/sgm_tomatoes.html (and this is in the everything-is-too-expensive SF Bay Area) I like the idea of nesting cages because they'd be easier to store. If I were going to spend that much on tomato cages, I'd spring for the folding ones, which I've seen reduced in price at the end of the season. But I usually grow 15-20 tomato plants, and I'm not willing to spend a couple hundred dollars on tomato supports! I wonder if they'd sell better at a nursery if you delivered a sample set to the nursery and included delivery in the price -- they'd take up a lot of room at a nursery, unless they have lots of surplus land. Or maybe you could sell them at a farmers' market? Or on craigslist?

I have found that the best way to secure your CRW tomato cages (can be the cheapest too) is to buy or find some old pieces of 1/2 or 3/4 metal pipe or tubing. I like 10-12 foot pieces. First I cut off the bottom rung of the cages to stick them in the ground. Then run the pipe through the cages, about 3/4 the way off the ground. Then at the ends of the pipe and somewhere in the middle, drive a steel "T" post. You can use strong zip ties or cable ties to attach the pipe to the "T" posts. Also, I attach the pipe to the cage where it runs through. After the tomatoes get big, the pipe is hidden. My girls also like to swing from them! Of course this method only works if you plant your tomatoes in a row. It is very strong. Three years ago, we had a very small tornado pass by our house in May. The tomatos were small, but the cages did not move. To bad the shingles were a different story! If you have a hard time finding pipe, don't buy new stuff unless you have extra money. Go to a salvage yard/recycling center/scrap yard and ask if they have any pipe. I have a salvage place that will sell it to dirt cheap. You could also check on Freecycle or Craigslist. Good Luck.
