CULTURE THAT REQUIRES CARE
The amateur rose-grower who has seen with i'm
patience how slowly the rose-bushes In his garden
become large and behed with disgust the stout
three year-od" plants shipped to him his order
by some dealer, would view with amaZement the
culture attained here and thenceforth deem nature

arlv II must be understood that the popular idea
of forcing" roses for winter blooming-i e. that
they are impelled to unnatural productveness by
excessive nutrition watering and heats all wrong
The rose has q will OF its own. and Will endure no
such Injurious nonsense. Abundant rich food, OF
lust the kind suited to Its taste, must be given,
but water II too much and yon will have BLACK
