This was made possible by the development of tree nurseries such as at Ty Mawr near Llanybydder, which could supply large quantities of hedgerow plants including hawthorn, blackthorn, and beech.
Roedd hyn yn bosibl oherwydd cafodd meithrinfeydd coed eu datblygu megis yn Nhŷ Mawr ger Llanybydder, a allai gyflenwi llawer iawn o blanhigion gwrych gan gynnwys drain gwynion, drain duon, a ffawydd.
