Roses are a popular gift on Valentine's and Mother's
Day. If you haven't noticed, there are now many varieties
of miniature roses on the market that can serve a dual purpose.
Use them as gifts on special occasions and then add
them to the landscape. They make great additions to rock
gardens or can be used as a short hedge. Better yet, grow
them in containers in your landscape so that they can be
moved indoors for decorating on special occasions.
Most miniature roses are hardy and will flourish for many
years outdoors if cared for properly. Miniature roses
given for Valentines Day should be kept indoors until the
threat of frost is past. Even though these plants are quite
hardy, they will not withstand frosts when actively growing.
For most parts of Kentucky it would be safe to transplant
these actively growing roses in early to mid
May. The plants will need a sunny location outdoors but
they should be introduced to full sun gradually. First
place the pots outdoors in a shady location and each day
move it to a slightly sunnier spot. After a week to 10 days,
the plants should be exposed to fairly full sun and be ready
to transplant.
Keep plants well watered, but water the base of the plant,
not the foliage. This reduces problems with disease. Also
fertilize regularly with a complete fertilizer according to
label directions. Remove faded blooms and trim back
longer shoots to encourage bushier growth. In late winter,
prune back at least half of the stem length, or even
prune back individual stems to the lowest, outward facing
bud. If your plants are growing in containers, sink the entire
container into the ground during winter, or cover the
containers with mulch to insulate the root system from
extreme cold.
Diseases such as black spot and powdery mildew may be a
problem on miniature roses as they are on the full sized
plants. Disease may be less severe if plants are placed in
an area where they receive morning sun and good air circulation.
Diseases can also be controlled with fungicide
applications. Contact your county extension agent for a
recommended list of fungicides to use on roses. The most
serious insect pest of miniature roses are Japanese beetles,
aphids, and spider mites. The beetles can be picked off by
hand, and mites and aphids can be controlled with sprays
of insecticidal soaps and summer oils that pose little threat
to humans or the environment.
So as you are shopping for flowers this spring, why not try
some miniature roses. The cost is similar to cut flowers,
and the plants can add beauty to the landscape for years to come.
