Not my plant. What would give the serrated petal edges?

Small world! When I was a child, my father was stationed at the US Embassy in London, and we lived in Gerrards Cross.

Welcome, Cynthia!

That’s certainly a new one to me! It does sound like a mechanical stress issue - cracks that enlarged???

I don’t think that’s an accurate assessment. Have you considered that the attitude might be one of “help support and maintain the standards”? Every such activity has “rules” that must be followed, and anyone participating must intend to hold fast to them, including understanding and applying...

BioSafe Systems – Simply Sustainable. Always Effective.. I suggest you contact them directly. A long time ago, when I carried their products, they were limited to only a few. Now they have many variations targeting different applications, so could probably advise you which one is closest to...

I like what you’ve done, but there maybe some cultural factors that can be used differently. For example, I’d probably control your “humidity-creating pump” with a humidistat. A timer works, and I suppose your household RH up there might vary less than it does in many places, but here the...

Rob, I’d be careful using drugstore hydrogen peroxide on “delicate” seed. That 3% stuff is barely stabilized using stannous chloride, so upon contact with anything organic or metal, it embarks on a strong, cascading decomposition process, release all of its energy pretty much at once. I’d...

My Lucky Girl, a gift from someone here, if I remember correctly, is redder, but not as nice in form. It's still one of my favorites.

Hah! Been known to do that myself.

His month-long journey ended 14 months ago…

Yes, indeed. Welcome. Are you in London proper, or a nearby location?

Paleness can be either from a nitrogen or magnesium deficiency. Water it with 1 teaspoon of Epsom Salts per gallon. That ought to perk up the green.

Annica, Kelpak is produced in South Africa and is certainly available in Europe. Do not be tempted to get another kelp extract, as they are very dissimilar in the efficacy. Kelpak has been used globally for over 40 years on food-, and fruit crops, nuts, grains, turf and landscaping plants. I...

Summer Sun was registered in 2006...

Welcome aboard, Annica. Don’t worry about your English. It’s better than that of many native speakers!

Lost mine to a greenhouse heater failure. Would love to have a good replacement.

Getting laid off sucks, but sometimes there's a silver lining to that cloud. After 28 years with the same company, I thought my position was pretty much sacrosanct. I had gained a real "problem solver" reputation, and was usually moved into positions that needed help. In late 2007, I headed...

This is only a guess…. but it sounds like some sort of systemic infection, which would lead me to treat the plant either with a probiotic, to see if that helps, or a copper-based treatment. I suspect it’s bacterial, but have no way to know that for sure, and both of the treatments can affect...

Thanks for those photos. It's always a thrill to see orchids in the wild.
