M'chaka (asanayambe komanso koyambirira kwa maluwa) pa kutentha kwa 12⁰C, feteleza amayamba. Zizindikiro zoyamba za kudyetsedwa kwa tizilombo tating'onoting'ono ndi timabowo ting'onoting'ono (1-2 mm m'mimba mwake) pamasamba. Masamba a inflorescence asanatseguke (pafupifupi milungu iwiri isanadutse), zazikazi zimayikira mazira mkati mwa masamba osakula ndikuluma kudzera pa peduncle. Mphukira imodzi imakhala ndi dzira limodzi. Yaikazi iliyonse imaikira mazira okwana 2 ndipo imawononga chiwerengero chofanana cha maluwa, omwe amayamba kufota, kupachika pamtengo, ndipo pamapeto pake amauma ndi kugwa pansi. Kukula konse kwa mphutsi kumachitika mumphukira yowumitsa. Kukula kumatenga mpaka masabata atatu. Nthawi zambiri, rasipiberi imatha kuwononga mpaka 60% ya masamba onse m'munda, zomwe zimapangitsa kuti pakhale zokolola zambiri. Mbadwo wachiwiri wa kafadala umapezeka kumapeto kwa June, umadya masamba kwa masiku angapo, kenako umatuluka m'nyengo yozizira.
