All Triumph Tulips can be forced into bloom in 
from three to four weeks, so that you can just about 
figure out when to bring them in the greenhouse, de- 
pending upon when you need the flowers. 
They need an abundance of tepid water and if an 
early flowering date is required, a temperature of 70 - 
75° F. should be applied. 
Triumph Tulips had best be forced quickly and as 
soon as the buds show color, move them to a cooler house, 
to harden the flowers. 
As Spring approaches, it will take less time to get 
Tulips in bloom and therefore the temperature should 
be dropped and light admitted. 
Darwin, Breeder and Cottage Tulips can be forced 
from January 10 on, depending upon the variety.
