My wife is a retired PT. She went to school at the Univ. of MD Med School in Baltimore. The cadaver they dissected was appropriately named "Annabel".

It’s a species, so the specific epithet should not be capitalized.

When I was an undergrad at Georgia Tech, I volunteered at "the public greenhouses in Piedmont Park" - now the Atlanta Botanical Garden. There were two greenhouses - I'm guessing 30' x 120' - side-by-side. The one I worked in was a rainforest and one end, transitioning to a desert at the other...

The original semi-hydroponic pot was a 1 quart deli container that had come home bearing won ton soup. Before I got out of the end of the business I must have sold 10,000 of them, plus 4 other sizes. Buy a 1/4" drill bit meant for plastics. The created nice clean holes and don't dump toxic...

ANY plant CAN be grown in semi-hydro culture, but that does not mean everyone can do so. With any culture choice, one must understand how it interacts with the rest of the multitude of cultural parameters to meet the needs of the plant. Because of that and the variations between growers, what...

All of my orchids are in inorganic media, as well.

After 50+ years of growing and experimenting, I have simplified by feeding regimen to feeding once a week via top-down flooding, with a 75-125 ppm N solution. (In winter, indoors, I feed every two weeks at double that concentration.) Divide 9.2 by the %N in your fertilizer. The result is the...

I believe that the recommendation for use of drugstore 3% hydrogen peroxide has been passed down from since before much was known about its interaction with plants. Such products are typically weakly stabilized with stannous chloride. Upon contact with metals or organics, the energy release...

Welcome, Nick.

You’re right, Harvey. It used to be that the “standard” or at least typical LECA was 8-16 mm. The stuff I sold as PrimeAgra was the 10-16 mm cut, but I find that most are even more variable these days. That said, in my experience, uniform, perfect spheres are not necessarily the best potting...

“Bouillie Bordelaise” translates to what we call “Bordeaux mix”. It used to be used more prevalently here than it currently is. Yes, copper is systemic.

That’s a little too broad of a statement for my mind. The most open volume occurs when all of the particles are perfect spheres of identical size, at roughly 40% open. Any size or shape variation reduces that. Having said that, perlite, being sharply jagged or “craggy” might interlock sharp...

Any copper-based product will be a systemic fungicide and bactericide.

If your ambient humidity is even just “adequate”, maybe you don’t need the bag. My plants are typically in 90F, 90% RH all summer, and I see no mold. Maybe it’s my use of probiotics?

To rescue a plant in that condition, I would immerse the entire thing in a 1 oz/gal Kelpak solution for about an hour, then pot it up, anchoring it with stakes or clips to keep it immobile, and watering it in with the Kelpak solution. I’d then invert a plastic bag over the plant and pot...

Nicely done!

Interesting. Why would a deposit of fossilized oyster shell have less sodium? If it's incorporated into the crystal structure, it's not coming out with age. If it's not in the crystal structure, then firing it should eliminate it anyway. If you are in a market that gives you options and you...

It is ground calcined oyster shell, not fossilized.

That tells me the particular dolomite he used was inappropriate, not that all dolomite is. Specific minerology, source, and particle size can all affect the dissolution rate. All biostimulants should be used sparingly, as overexciting the natural processes of a plant can have negative side...

Why not dolomitic lime? Ag lime is primarily CaCO3, dolomitic lime throws in some magnesium, another important element. If you’re going to make such suggestions, how about explaining why or why not?
