Please disregard this post which I meant to place in the regular forum.

Hi! This may not really answer your question but I thought I'd add to the conversation since I am in your zone (17) and have mostly containers in my brick patio. I have several large ceramic pots and I have a couple with dwarf trees and a couple with with shrubs in them. Those are like the backbone of my garden~ the woody stemmed plants that I consider "permanent". Then I have several other pots that I plant with combinations of annuals & perennials in a single pot~ herbaceous stemmed plants~ I'll change the annuals every few months with whatever I find at the nursery that has the same watering and sun/shade requirements as the perennial(s) i'm planting it with. The perennials will last a few seasons but when they stop blooming or look tired & ragged, Iknow it's time to pull them out and plant something new. (Perennial just means it lives for 3 years or more~ they do not last forever!) But some good evergreen trees & shrubs for containers that look good year round are Purple Dodonaea, dwarf citrus, Nandina, Chamaecyparis lawsoniana & other dwarf conifers, some Azalea/ rhododendron cultivars, boxwood, Dwarf Alberta Spruce. Also, I like to use organic fertilizers because they improve the soil over time and provide a lot of nutrients but I also use Eleanor's VF-11 diluted in a spray bottle w/ water and just spray it on all my plants once or twice a month. Every plant is different so even though they may all be perennials, some respond well to being pruned, others may not not bloom if you prune. Some plants don't like fertilizers (ie. ferns) while others are heavy feeders.

Is it a single-ended or double-ended bulb? If it's single ended, it should have an outer envelope that acts as a shield and filters out most UV, so you should be fine. If it's double-ended, it doesn't, and you should have a piece of glass between the bulb and.. well, everything else.

I have 12x12 Ceramics here, LOTS of it, and I've always used the Swiffer with fantastic results. I'm having Porcelain, laid on a diagonal installed in the kitchen in my new home that's about 2/3's built, and I was under the assumption that I'd clean it just as I did Ceramic. Hmmm, I'd be interested to see the responses here.
