|Weight||Tubers / carton|
Most cut flower growers prefer a minimum of 5-7g tubers for commercial cut flower production, however some have achieved good success with 3-5g planting stock. The heavier the tuber, the more bells and taller, stronger stems.
Tubers heavier than 5g are often 'split' prior to planting, as the second growing point can often be much later and weaker than the first dominant point.
Wait until at least the first two or three bells are fully orange, with good bud development further up the stem. If the flower is left to fully mature before cutting, the vase life will be considerably shorter.
