I checked to forecast and towards the end of the week the highs will be in the 50s and lows in the lower 30s. I really want to get it planted as soon as possible because it looks a little ragged right now. I was able to amend the soil with plenty of composted cow manure so that I don't have to worry about it when its time to plant. I almost lost it last year because every leaf kept getting scorched. I had to put an umbrella over it to protect it from the afternoon sun. Hopefully it will be more tolerant of the heat this year. I planted a few things in my garden the past week. That's wonderful about the hostas, I've never been able to keep them alive. I'm sorry to hear about your phils, but at least your hibiscus made it. I have a white fly infestation thats killing off my plumerias and other houseplants. I've sprayed them with a mixture of dish soap, alcohol and water, but somehow a few make it and then I have another bad infestation. I finally just gave up, and I'm anxious to put all my plumerias outside so other predators can eat them.
