Hello, again, Penny, I have no idea whether calcium nitrate is formulated for local soils. I do know that my friend in Venice with the macadamia tree went to 4 nurseries and could not find it; but our local one did and the results have been spectacular. With large artichokes, one can separate the leaves a bit and fill the spaces between the leaves with herby bread crumbs and olive oil and steam them. A large one like that can serve two. Our favorite way, requiring the least fuss, is to pressure cook them for 12-15 minutes, depending on the size (12 minutes for the smaller ones), then dip the leaves, hearts, either in mayonnaise or, my personal favorite, olive oil, balsamic vinegar, with a little salt and pepper...which is really a vinaigrette. When the big ones are pressure cooked, the stems are almost entirely edible, so I cut long portions of the stem, which tastes just like the heart. Most of the recipes I see call for removing the outer leaves and utilizing only the inner portion, the heart and bottom. I find that a horrendous waste, as we love scraping the goodies off the leaves with our teeth. One of these fine days, I will remove the leaves and proceed as directed, but will reserve the leaves to steam, another day. Well, I am off to battle mildew another week. It seems like this May-June for bank has been with us for most of April, and the result is persistent mildew. I have tried Funginex, neem oil and E-Rase (Jim D's personal choice, IIRC), all with moderate effectiveness. What we need is warm sunny days, days not so hot as to fry the roses, but warm enough to give them a fighting chance. It seems that even at one of the local country clubs, where a neighbor works, with its fleet of professional landscapers, are unable to do any better than we at holding the line against mildew. Onward and upward! Be well and enjoy your garden! Ron
