I didn’t find the thread you’re talking about. Anyway, I believe that you will eventually grow enough khat so that you can sustainability harvest. I believe that I will be at that point next year, and I live in Georgia. I’ve not been very successful with the wide leaf variety, but the narrow leaf seems to be very hardy in every way. Khat grows fairly slow the first few years, so it takes a good four years or longer. Mine are about 4 years old and they are growing fast now. They all started putting out a lot of new growth from the bottom of the plant this summer. The bad news is that so far I haven’t gotten anything out of chewing it, although I’ve only tried a few times. There was an excellent thread on another forum by a guy that grew khat professionally in South Africa. That thread was even linked here when he joined briefly, but it has since been erased from the internet entirely. According to him, aggressive pruning and frequently picking one third of the leaves on the plant is absolutely necessary to get the plant to produce cathinone. I’m going to start that process next year, I’m hoping for the best. Regardless of that, it’s a beautiful plant that is very easy to grow, bugs don’t touch it, and it does extremely well as a house plant during the winter. It’s my favorite entheo plant.
