Lynn's a true cactus fan and this video shows it!
If someone gave me a specimen like that I'd probably wet myself.
My lophs have recovered from some extensive crusting after a bit of careful feeding with straight urine. Maybe Lynn needs to pee on her 'yote, too - or get Hans to do it for her!That certainly is a massive and ancient lophophora. I have no idea how old though.
I had similar insect damage on my cacti and successfully treated it with Captain Jack's Deadbug Brew after sunset. If you decide to use the same product, be careful not to buy the Captain Jacks Insecticidal "Soap". I have read that the "soap" version damages cacti. It's very important to distinguish the two treatments and choose the proper one. The insects enjoy the soft tips of Trichocereus. That is where I noticed the damage.
I am not going to be proactive by pre-treating. I don't want to create treatment resistant bugs. I just keep an eye out for the first signs now so I catch them early.
Yeah, totally - and that's why I'm going for cautious application, interspersed with normal watering to flush the soil a bit. The natural equivalent would be occasional sprays of animal urine as a punctuation to whatever rain usually occurs.But then again it could also cause root burn and unwanted bacteria etc into the soil harming the plant.
