So that combo you've got going there is nice in theory, but . . . those azaleas need to move to somewhere with morning sun at most. In a few years when that climbing rose gets big and makes some shade there, maybe you can plant azaleas again with more success.
If you were having your "usual" Pac. Northwest summer, they might not have fried, but this year? Too hot for newly planted azaleas, for sure. Also always mulch everything that gets hot afternoon sun, it will not only help prevent weeds, it keeps the soil cooler and retains more moisture.
dyzzypyxxy said:You can get a soil test kit at Home Depot or Lowe's and do it yourself, or you can take a soil sample to your County Extension office to be tested. If you want more than one sample (eg. from several places around your yard) it's much more efficient and cost effective (here they charge $5 per test) to get a kit of your own. The kit to do 10 tests was about $10 last time I bought one - a long time ago.
dyzzypyxxy said:There are some sort of mauve-y roses, and many very dark reds but so far I don't think roses actually come in purple.
People do plant clematis as a companion plant to roses, though. They sort of climb through the rose branches and it makes a beautiful display. There are many stunning purple clematis, including Jackmanii, an old classic and her many progeny.
