Ukuvuna kwekhabethe kwenziwa ngesandla ngoba ukufakwa kanye nokuvuthwa kwesithelo kufanele kunqunywe ku-in situ yi-picker. Ungadonsi ikhaloni emvinini. Sebenzisa ummese obukhali noma i-shears ukusika isiqu se-watermelon ngokuhlanzekile, ushiye cishe u-4 cm we-stem phezu kwe-melon ukuvimbela isilonda ukubola nokubhubhisa i-watermelon.
Isithelo kufanele sivuthiwe ngokugcwele uma izithelo zikhethwa. Indlela engcono kakhulu yokusungula ukuvuthwa inomthamo we-refractometer. Thatha amasampula kuwo wonke amasimu akho futhi uma uBrix (okuqukethwe okushukela) engaba ngu-9 kuya ku-10% insimu kufanele ilungele ukukhetha ukuqala.
Lokhu kukuvumela ukuthi uhlole umbala wangaphakathi wenyama yezithelo futhi wenze izivivinyo zokunambitha. Ezinye izinkomba kukhona ukomiswa kwe-stem stem bese ushiya eduze kwesithelo sesitshalo esibonisa ukuthi izithelo zivuthiwe futhi asisatholi ukudla. Enye ingomsindo ozwakalayo lapho izithelo zifakwe ngesandla sakho.
Ukuvuna kwensimu efanayo kuvamise kwenziwa kabili noma kathathu ngaphambi kokuba zonke izithelo zikhethwe. Ukuvuna ekuseni kakhulu ezindaweni ezipholile.
