Chimodzi mwa zigawo za chisamaliro cha chitumbuwa ndi kudulira, zomwe zimangothandiza kupanga kapangidwe ka korona wake, komanso zimapangitsa kuwonjezeka kwa zokolola ndi moyo. Ntchitoyi ndi yofunika kwambiri kwa mtengo, kotero aliyense amene akufuna kusangalala ndi zipatso izi ayenera kudziwa nthawi ndi momwe angachitire.
Momwe mungakonzere mazira a chitumbuwa?
Kudulira mitengo ya chitumbuwa kumachitika bwino pakati pa kasupe (kumapeto kwa March - April), mpaka masambawo akufalikira pa izo. Chifukwa chakuti kuyamwa kumatuluka panthawiyi pamtengo sikudalibe mphamvu, zilonda zidzatha kuchiritsa. Kudulira kumachitika pachaka, malingana ndi msinkhu wa mtengo, chiwerengero cha nthambi zokha chimachotsedwa.
Cholinga chofunika kwambiri chomwe chiyenera kukhazikitsidwa chifukwa cha kudulira ndizokonzekera bwino kwa nthambi. Kuti muchite izi, chotsani zomwe zimakulira pafupi, kukhudza kapena kukhala motalika kwambiri. Nthawi zonse ndi koyenera kudula nthambi zonse zolema ndi zouma, kuti zisawononge kufalikira kwa mliri mumtengo.
Korona wa maula angapangidwe malinga ndi mtundu wa chitsamba kapena mtengo wochepa. Pachiyambi choyamba, zidzakhala zofunikira kuti muchepe korona ndikufupikitsa mphukira. M'chiwiri - choyamba (zaka 3-4 zoyambirira) korona wochepa kwambiri yayambitsidwa, ndipo pokhapokha kudzakhala kofunikira kukhalabe mawonekedwe ake. Ndibwino kuti nthambi zikuluzikulu (ziyenera kukhala zidutswa 5-7) zimapangidwa pamtunda wa masentimita 75-80 kuchokera pansi.
Chofunika kwambiri ndi kuunikira kwa korona, komwe kumapezeka ndi kudulira pachaka, kwa mitundu yambiri ya chitumbuwa chotchedwa cherry plums , monga yaikulu kwambiri "Kuban comet" kapena "Sarmatka". Izi zili choncho chifukwa chakuti pamene nthambi zowonjezera, zipatso zimakhala zazing'ono ndipo nthawi zina zimasintha mtundu.
Pamene kudula mtengo, m'pofunika kukumbukira kuti ukadulidwa, umayamba kukula mofulumira, choncho njirayi ingagwiritsidwe ntchito pokhapokha mitengo kapena nthambi zikukula.
