The Bolivian cactus Rebutia pulchellaWhat ’s wrong with hoi polloi ? Why do n’t other people grow these ? Ther are SO many genus and metal money of various South American Cacti that are noteworthy growable ; plant that just require the elementary condition of a cold dry winter windowsill that is sunny , or a poarch that does n’t freeze , or a garage window , where they can be forgotton , literally , from October until April , and then watered . And look what happens .
Now , granted , I never really had succeeder with these plants until I built the nursery , where they make it total neglect and misuse , but I think I am having some winner because they can get ice cold , near freezing , which is what really activate them to blossom , and I can keep them os dry and still give them verbatim sunshine through individual pane glass . But I do cognize that I have a studio apartment way that is unheated with southerly exposure windows , so one could sample these over - blooming cacti if you have such a place as a cellar window that stay cold in the winter and gets Sunday .

I first became introduced to these blooming cacti during a visit to the Chelsea Flower Show one year . A gentleman there show an striking display of cacti , in fact , almost unbelievable in it ’s diversity . I then foudn a rule book on Echinocerus publishedc by Kew Monographs , where it spill the beans about the popularity of aggregation in the UK of blossom cacti in unheated small greenhouses , much like an alpine house . Here in America , I think it gets too moth-eaten in the north east for many of these South American beauties , but there are many other cacti that can live out of doors if given the ripe weather . But I want to produce these in pots . After obtain a few genus to try out , I discovers that there are many Bolivian cactus that have an amazing range of flowers . Rebutia , Lobivia , Notocactus – test google and see what you’re able to find . Even on eBAy , there are many uncommitted , most under $ 5.00 US .

I pot my appeal up in a on the loose , profligate draining mix composed mostly of grit and pumice stone , with some peat and perlite added . The plant are kept in the sunniest part of the greenhouse year round , and simply get waterd occaisionally starting once buds make in May , and then throughout the summertime . In the crepuscle , I withhold water system , and the pots are push up right against the glass , where they get full sun in the winter , but ever frost over a bit on cold nights when the temps ouside fall to below zero F and the glass frost over . This dusty , triggers the plants to bloom , and many cacti can indeed freeze if they are kept dry , and the cubicle wall are less turgid . A aggregation of blooming cacti at the Chelsea Flower Show
