Re: Pterocactus in flower

I find there is a trade off between number of stems and number of flowers and pot size. As more stems develop each year you get more flowers, then at some point the plant runs out of steam and produces mainly smaller non-flowering shoots, at which time it is due a drastic haircut :grin: . Mostly I g...

Pterocactus in flower

I find this much easier in a hanging basket, as I am less likely to knock the fragile stems off.
A pleasant surprise when I went into the greenhouse this morning.

Every few years I take off all the shoots and let it grow from scratch. I last did that 2 seasons ago.

I just noticed this set of buds peeking out of my largest seedling (22mm dia) from a sowing in 2011.

Re: My battle with the bug

Dip each plant roots and stem in a neonicotinoid insecticide , allow to dry, pot up. The likelihood is that will sort the problem. I had a similar failure of quarantine a few years ago having been RMB free for 20 years. I just root washed and dipped the obviously affected plants though, and drenched...

Re: Orange damage on Coryphantha

I would suspect thrips from the damage distribution rather than mites. Thrips often lurk under wool and cause damage which becomes visible as growth ages. I can clearly see thrips damage on the spines in your photo ( pale banding with small black spots). Thrips tend to attack certain plants and leav...

Re: Current Treatments For Red Spider Mite

No mention in the above of predatory mites! If you have an outbreak of mites (flat or red spider) on newly acquired plants and the rest of your collection is mite free, it is worth trying to eliminate the mites entirely with one of the contact sprays based on plant oils, as resistance to the spray i...

Re: BCSS Forum Seed Pool

Germination of caput-medusae is quite variable and seems to depend on the age of the seed. Fresh seed germinates in about 5 days at reasonable temperatures and old seed can take a couple of weeks. Well stored seed seems to keep its viability compared with some other species. So you should get a reas...

A Good Day for Avonias

It was 38C in my greenhouse at 12 noon today despite all vents and doors being open and 3 fans running. Not so nice for the orchids, but the Avonias seemed to like it. You can almost set your watch by them... At noon , A. harveyi and A. albissima IMGP4280.JPG IMGP4288.JPG A. quinaria ssp alstonii an...
