Amazi nimwe mubikorwa nyamukuru byo kuyobora ibimera bya Bonsaa. Amazi asa nkaho aroroshye, ariko ntabwo byoroshye kuyahira neza. Amazi agomba gukorerwa ukurikije amoko y'ibimera, impinduka zigihe, igihe cyo gukura, igihe cyindabyo, igihe cyo gutonyanga, igihe cyo gukora ibihingwa. Kumenya igihe n'amafaranga ni ngombwa cyane kugirango iterambere ryibimera. Urupfu rwibiti bimwe na bimwe bya Bonsaa bifitanye isano itaziguye no kuvomera bidakwiye.

Usibye gutanga amazi n'intungamubiri zo guhomba, ubutaka bwa Inkono nabwo bukomeza ibimera 'guhumeka bisanzwe mu kirere. Iyo ubutaka bwinkofu bufite ubuhehere buhagije, ibice byubutaka byaguka, kanda umwuka mumazi hagati yingingo, bigatera kubura umwuka mubutaka bwafutswe; Iyo ubutaka bwumutse bwumye cyangwa bwumutse, ibice byubutaka bigabanuka, amajwi ahinduka muto, kandi icyuho kiri hagati yinkuta zigaragara. Icyuho cyuzuyemo umwuka.

Mugihe ubutaka buhinduka hagati yumye kandi butose, umwuka mubutaka bwubutaka nawo uzenguruka kandi ubudahwema, wemerera imizi yibihingwa guhumeka bisanzwe. Nyuma ya buri mazi, imizi yibihingwa izashobora kwihanganira kubura ogisijeni mu butaka bwinkofu mugihe gito. Ariko, niba ubutaka bwinkono butose igihe kirekire, bituma hatabaho ogisijeni ndende, bizatanga isuri nizindi ndwara; Niba ubutaka bwumutse igihe kirekire, nubwo hariho ogisijeni ihagije mu butaka bw'inkofu, ibimera ntibishobora gufata amazi igihe kirekire, bikaba byangiza imikurire y'ibimera kandi bishobora no kubatera gupfa. Kubwibyo, mugihe cyo kuvomera ibimera bya Bonsaa, Ihame rya "Ntukayashyireho Iyo Byumye, Zizirika neza" zigomba gukurikizwa.

Kuvomera bidahagije no kubura ibimera bizatera amashami yo kwigomeka no kumeneka, hanyuma amababi yumye, ahindukira umuhondo, agwe. Ku bijyanye n'ubwoko bwerekana, inshinge zizaba zoroshye kandi zikabura kumva ko zikomeye kandi zijimye. Iyo ibura ry'amazi rikabije, cortex y'ibihimba igabanuka nk'ingagi. Niba uhuye niki kibazo mu cyi, ugomba guhita wimura igihingwa ahantu hatutswe. Nyuma yubushyuhe butonyanga, butera amazi kumababi mbere, hanyuma usuke amazi make mu nkono, hanyuma usuke amazi neza nyuma yisaha imwe.

Ku bimera bikabije, menya neza bitarenze icyarimwe, kuko iyo igihingwa kiva cyane, umuzi cortex wagabanutse kandi uri hafi ya Xylem. Niba umubare munini wamazi watangwa gitunguranye, sisitemu yumuzi izaguka kubera kwinjiza amafaranga byihuse, bigatuma correx yo guturika, bituma habaho gutontoma, hagomba rero kuba inzira yo kurwanya imihindagurikire. Nyuma yibihingwa bigufi byamazi birimo kuvurwa hejuru, nibyiza kubikomeza munsi yigicucu iminsi mike, hanyuma ubishyireho izuba nyuma yo gukomera. Ariko, ntukarengere amazi. Usibye gutera ibihingwa bikura, bigira ingaruka kumiterere yigiti hamwe nagaciro ka mirongo itambarika, amazi menshi arashobora kandi gutera amarekura imizi nurupfu. Amababi ya Bouature Bonsai asaba ubutaka buke, bityo rero ni ngombwa cyane kubirwa mugihe gikwiye kandi muburyo bukwiye.
