Culture of Sub-Zero Roses 
Upon arrival submerge roots in pail of thin 
mud until planted.; make hole shape of in- 
verted pail; fill in center three inches high; 
spread roots; half fill hole with clean crum- 
bly earth; pack firmy; add one-half pail 
of water, damp earth and rain are no sub- 
stitute for this watering; hill up plant with 
clean loose dirt, to be removed in one week. 
Sub-Zero Hybrid Teas require no winter 
protection. They can survive below ground 
and live many decades. All rose wood on 
Sub-Zero Hybrid Teas and Climbers may if 
unprotected be destroyed by temperatures 
around 15 degrees below zero or colder. 
Do not dig up for dead if killed to bed level. 
Like a peony from eyes below ground nor- 
mal live plants can grow from live roots, 
by early rose time, larger each year, even 
after very low sub-zero. It is estimated 
that winter mortality of Sub-Zero Hybrid 
Teas is around 1 per cent, where tender hy- 
brid Teas fail 30 per cent. In sub-zero 
areas, fall hilling up, or the “thermos” sys- 
tem insures larger plants in the spring, pro- 
tect against heaving in damp or heavy 
loam with consequent breaking of roots and 
destroying plants.
