樹豆的花序屬於無限生長，以致樹豆開花、結莢及豆莢成熟時間參差不一，即使同一品種也要相差15-30天，在採收上無法一致，尤其低海拔淺山坡地種植的樹豆，在十二月莢果以成熟轉赤褐色時，尚有枝條綻放黃色花朵或約有8~20%莢果還在青綠或略呈淡褐色階段，而且有部份葉子並無明顯黃化或凋謝，略為半落葉性(臺東無霜地區，冬季平均最低溫度鮮少在16℃以下)，翌年三月以後樹豆又開始萌芽，以著生之莢果也陸續成熟，若善加以整枝、施肥、除草、培土、灌溉，妥加管理可以使產期提早30~45天，樹豆之再生栽培方式若能推廣利用，節省生產成本，必更具有發展的潛力。 英文內容大要：The tree bean inflorescence belongs to the infinite growth, so that the tree bean blossoms, pod and the bean pod mature time diversity not one, even if the identical variety also must differ for 15-30 day, is unable consistently in the recovery, especially low elevation shallow hillside planter tree bean, when December pod fruit by mature extension russet, still had the branch to bloom the decadent flowers either approximately has 8~20% pod fruit also in dark green or slightly assumes the beige color stage, moreover had the partial leaf and the not obvious etiolution or dies of old age, slightly half fallen leaf (Taitung non- frost area, winter equally most low temperature fresh is short in 16 ℃ below), the next year March later tree bean will start the seed, to will be living the pod fruit one after another to be also mature, if friendly will perform to prune, to apply fertilizer, the weeding, earths up, the irrigation, the proper Canadian management will be allowed to cause the childbirth time to shift to an earlier time the 30~45 day, will set up regeneration cultivation way the bean if will be able to promote the use, will save the production cost, must have the development the potential.
