Costs And Returns Of Daffodil Forcing

Some consideration must be given to the price and performance of various varieties where they are to be grown indoors commercially. For instance, Double Nose a bulbs of Golden Harvest will cost twice as much as Canton. Both are excellent selling varieties – but under forcing conditions, whereas Canton will take a full month to yield its full quota of blooms, Golden Harvest will require only three weeks – which will mean that the greenhouse space may be quickly utilized for another crop.

Again, the size of bulbs is another consideration – Golden Harvest makes a mature bulb of almost half the size of that of King Alfred, which means that almost double the number of bulbs can be accommodated in the same area of the greenhouse.

Earliness in forcing is another factor. Golden Spur may be forced from early December and will be clear of the greenhouse by early February to allow for another variety to be forced while prices are still high – and while the price of fuel remains higher than ever, the high price of a quick-maturing variety will be offset by the use of considerably less fuel. Only by growing and experimenting with several new varieties each season can the commercial grower determine which will prove most profitable.

The use of low-storage temperatures will induce earliness of flowering, but time of lifting the bulbs is important, for there is danger of damaging the bulbs through over cooling in temperatures of 48° F. The Dutch growers lift at the end of July and keep the bulbs in a temperature of 48° F. until late September. The bulbs should be boxed as soon as possible after arrival on the nursery and kept as cool as possible until taken into a temperature of just under 60° F. about the last day of November. They will then come into bloom early in the new year.
