ENCYCLOP.MDLA OF GARDENING. 
following winter & spring. Plant bulbs about two-thirds of their 
depth singly in a 5-in. pot, or three in a 6-in. size. Pot firmly. After 
treatment : (a) Plunge pots to their rims in bottom heat, 75° to 85°, & 
give one application of water only until growth begins, then remove 
to a shelf near the glass in temp. 55° to 65°, & remove to temp. 50° to 
55° when in bloom. (b) Place pots on hed of coal ashes in cold frame, 
cover with 4in. cocoanut-fibre refuse, & give no water until growth 
begins. After this, remove the fibre refuse, water moderately, & 
transfer most forward plants to the greenhouse. (c) Pot bulbs in 
April, plunge pots just above rim in a sunny spot in garden, keep 
moderately moist, lift pots in Sept. or Oct., & place in greenhouse to 
flower. Water freely when in full growth. Syringe foliage fre- 
quently. Apply stimulants (}0z. guano or Clay’s fertiliser) once a 
week when growing freely. After flowering, bulbs of no further 
use.
