Hi Paul That plant is from one I originally bought from an old chap who was selling out due to ill health. It wasn't showing any colour when I first saw it and I didn't know what it was, but he said it was nice when it coloured up and I took his word for it and bought it. Since then it just continued to multiply to the extent that I now have them all through my front garden which at the time of planting was suffering badly from visiting cats damaging anything I planted; not any more, they don't like the prickles! What I like about them is they can take all the sun they can get,(even the Jan 43 degree C. day) without any damage and when they colour up in a large group they are quite eye catching. If I can find a pic of the garden bed I will post it and you will see what I mean. All the best, Nev.

Hi Prairie_north: Very pretty bloom on your mini-rose. Thank you for the l info. that cracked corn changed from pink (acidic) to purple (neutral) fast. I'm happy with cracked corn in the planting hole (did that last year), so is Momscottagegarden (clay soil). I like what you wrote: "The bed around it was originally amended with peat moss, and has cedar shavings on top. Today I pushed the shavings away, dug up the soil around it, put down some sheep manure, and red lava rock." Peat moss mixed with clay becomes hardened a year later. Cedar shavings is acidic (pH 4) that would leak acid down when it rains (pH of rain is 5.6). Since mini-rose is own-root, the roots are nearer the surface, and is sensitive to acid leaching down. Own-roots do best with organic fertilizer, since it's nearer the surface ... some are wimpy like alfalfa sprouts, versus big-woody-bush-trunk Dr. Huey. Red lava rock is a strong buffer at pH 8. I mulched roses with that during our wet months .. kept roses clean. Blooming takes up lots of potassium & calcium to make those firm petals. After blooming, potassium and calcium are both depleted, plus rain leaches out potassium & calcium & trace elements. Red-lava rock in the planting hole, plus on top provide a continuous supply of potassium to prevent diseases, plus more blooms. Calcium is a strong buffer: I use that in many ways: as granular gypsum (calcium sulfate) to break up clay. If it rains a lot, I put gypsum on top of red-lava-rock. But for Dr. Huey-rootstock, I put dolomitic lime on top, since Dr. Huey likes it alkaline. Best ratio in hydroponics setting is equal nitrogen to potassium, 1/2 phosphorus, and 1/2 calcium. I burnt a few own-roots with either salty manure in hot weather, or high-phosphorus fertilizer like bone meal. My best result in hot weather is alfalfa hay for nitrogen. Timothy hay is much softer, easier to mulch .. that's what I plan to test next. I got amazing result mulching with alfalfa hay in hot weather, best nitrogen-source ever, which beat anything I tested: blood meal, compost, Milorganite, alfalfa pellets, alfalfa meal, corn meal. The problem with alfalfa in smaller particles: they gunk up on top, either souring, or hardening clay further. Alfalfa hay is fluffy, which cools and shade the roots in hot sun, plus it's a strong buffer: neutralize both acidic rain, and alkaline tap water.

Dcarch, I've been considering ordering an infrared thermometer for a long time, thanks for providing a few uses for it that I hadn't thought of! (a little extra justification never hurts!) Jadeite, thanks for pushing me over the edge by providing the link to the sale at Thermoworks. I've purchased a few items from them, and I'm on their mailing list. I don't know why I didn't get that email! DebraK, I had and threw out a number of digital thermometers because I couldn't trust them to be accurate. I asked for, and received, my Thermapen for Christmas a year ago and I use it all the time. It's accurate and reliable, and best of all it has a very slim, very sharp probe that can be used on thin things, like a steak, thin pork chop, or pounded chicken breast or even fish (though it's easy to tell when fish is done). I have also used it to find out how hot foods are in a warming tray on my Thanksgiving buffet--and also how cold a salad is, so I know when to put it back in the fridge. I've also used it to measure the temp of hot water for brewing green tea or coffee, and the temperature of the water going into the fish tank, and various other things. It's one of the most used things in my kitchen, and I count it very much worth the money spent. Cj

Tricky? Not really. Place one or two squares of nylon window screening in the bottom of the inverted top. I use such in regular pots without issue. For stability, rocks can be placed in the bottom section. Furthermore, if this is just to test the media, the weighted bottle could sit in a terra cotta pot or a shallow hole in the ground, or braced with bricks, or any number of other cheap, down and dirty solutions.
