La I-Welwitschia mirabilis isitshalo esiyinselele kubo bonke abayimilutha enoshukela. Akukhona ukuthi ihlobisa ikakhulukazi, kepha kunzima kakhulu ukunakekela ukuthi ukuphumelela ngakho kuwumthombo wokuziqhenya.
Futhi ngukuthi ukusuka kwenye yezindawo ezome futhi ezishise kakhulu emhlabeni, ukunquma ukuzama ukuzivumelanisa nesimo sezulu esibi kaningi kuphetha kabi. Ngaphandle kwalokhu, le yibhulogi ephathelene neziphuzo, futhi kufanele kube namafayela kuzo zonke izinhlobo zezinto eziphilayo: I-Welwitschia mirabilis Awukwazi ukuphuthelwa.

Izimbali zivela esiqwini esibulalayo maphakathi nesitshalo, futhi zinombala osawolintshi. Imbewu yizitshalo, ezinamaphiko alaminar, futhi zikala cishe u-2cm.
Ziyini izinkathazo zabo?
Ukuze ube ne I-Welwitschia mirabilis ngezimo kufanele itshalwe embizeni enkulu, ejulile ene-substrate egeleza kahle kakhulu. Eqinisweni, kunconyelwa kakhulu ukuthi umane usebenzise i-pumice uwedwa noma uxutshwe nesihlabathi somfula esigeziwe. Ngaphezu kwalokho, kufanele unisele kancane: kanye njalo ezinsukwini eziyi-10-15 ehlobo futhi nyangazonke unyaka wonke.
Kodwa-ke, ngeke kusize ngalutho ukuba nayo ku-substrate enhle kakhulu uma isimo sezulu singesihle. Izinga lokushisa eliphezulu lingaba ngu-40ºC ngaphandle kwenkinga, kepha ubuncane akumele behle ngaphansi kuka-0ºC. Uma kwenzeka ikwenza, kuzofanele siyivikele endaweni ebamba ukushisa okushisayo.
