PRUNE. PLANT bare-root roses. Prune
roses at their dormant stage, usually about the middle of the month. The
aim is to renew the plant by removing very old growth cleanly at the base,
leaving no stubs. Dead and twiggy branches are eliminated and branches
crossing the center of the bush are removed. The remaining canes are cut
back, always to a lateral which is then shortened back to an eye pointing
to the outside of the bush. This is also the ideal time to plant bare-root
roses. Plant in the sunniest spot in the garden, protected from the
prevailing winds, in well-drained soil.
Apply a top dressing or
organic compost, fir bark or steer manure. As leaf buds begin to break rub
off any that will grow into the center of the bush. Continue to do this
throughout the growing season. Scatter snail bait around the
Supplement the rain with generous
irrigation, using a water wand. Control aphids by spraying with a
recommended insecticide. Lightly cultivate the soil as soon as it is
friable after a rain.
Apply a complete commercial fertilizer,
6-9-6 or similar proportions. Scratch it lightly into the soil and water
immediately. Start a preventative fungicide spray program to protect the
roses against rust and mildew. Follow spraying and fertilizing
recommendations of your local nurseryman or Rose Society.
Time to fertilize with a ground application
or foliar feeding. Use a balanced fertilizer. Grandular fertilizers are
superior to foliar fertilizers. This is the month of Roses. Enjoy them in
the garden or cut them for indoor decoration. Always cut with sharp shears
to a vigorous set of leaves pointing to the outside of the bush. Maintain
your watering and spraying schedule
Basal shoots make their appearance. Learn
to differentiate between "good growth" and "suckers." The
latter start below the graft union, below the soil surface, and should be
pulled off, not cut. "Good growth" starts from above the graft and
will be your future bush if properly treated. When about 16" long, pinch
out the top. This will encourage it to branch out. Maintain
Second Rose bloom appears. Fertilize
lightly early in July. Cut all blooms before the petals drop and keep the
soil clean of spent leaves and petals. Water as needed to keep up the

Cut down on fertilizing. The
grower may use a 0-10-10 fertilizer or it is best to just stop
fertilizing entirely for the balance of the Rose season. Maintain watering
and spraying schedule. Prepare the soil for future plantings by digging
deeply and adding humus: bone meal alfalfa meal, and peat
