I've had some cacti and succulents for at least 8 years but only started collecting Echinopsis about 4/5 years ago.
Seedlings start flowering at about 3/4 years old and as they get larger they produce more flowers. The most flowers i have had open on one plant at one time was earlier this year with 8 flowers open but with much older plants it isn't unheard of to have 30ish flowers open at once!!! Some of them flower in groups and have multiples open at once which then all go over at the same time and then have a gap until the next batch flower, others flower continually but with only one flower open at a time but as soon as that goes over the next opens. Some of them pup prolifically and some rarely produce pups, this also can vary hugely between growers, some plants will pup with some people but not with others and so on.
They need to go to less than 8 degrees over winter for them to flower well, the flowers started at the end of march and will go on till late summer/autumn. The flowers open during the day and close at night, the flowers can last anywhere from one day to over a week depending of the exact cultivar and the temperatures, the hotter it is the shorter the time the flowers stay open for.
They appreciate a far larger root run than most cacti and do better in a larger pot, I start watering when the last of the frosts have past and start by watering ever 2 weeks or so, then by April I water them whenever the pots start feeling light or they furrows between the ridges become more prominent, when they have enough water the furrows and ridges will barely be visible around the lower part of the cacti due to all the water they are storing, I water like this throughout the summer and into autumn, when the first frosts start in October/November i stop watering and do pretty much nothing to them throughout the winter. They grow a lot during late spring and through the summer with offsets being started to be produced around now.
There are hundreds of different cultivars, I have 60-75 different ones I think!
Thanks for the comments.
