Cascade
Culture
Here we have a
guide for growing Cascades for the best possible results and effect at blooming
time. As you can see from the pictures below they can be a wonderful feature in
any garden.
Selection of Cultivar: We list under cascades those best suited to this
form of training. They must be small free flowering cultivars with limber stems
and good branching habit.
Potting Soil: Most any light well drained potting mixture can be used, or
combine 2 parts fibrous loam, 2 parts leaf mould or aged fine pine bark, 1 part
rotted manure, 1 part coarse sand and 1 part peat moss.
Planting Time and Containers: Cuttings should be rooted as soon as
possible, generally September to October. Plant initially to a 4” pot, repot to
a 6” pot after 4 to 5 weeks. Final container size will depend on the amount of
growth achieved; usually 8” to 12” containers are sufficient. When planting to
the final trellised container, plant the cascade on its side facing the trellis
so it can immediately be tied into place. A horizontal growing position is
maintained through most of the growing season.
Feeding and Watering: Apply a slow release fertiliser such as Osmocote
14-14-14 at each potting, plus a liquid feed with fish emulsion or other similar
feed every 2 weeks during the entire growing season until the buds show colour.
Top dressing with manure or fine pine bark will help conserve moisture. Do not
feed or spray insecticide when plants are in wilted condition.
Wire Support: Proper training and tying to wire trellis is the secret of
growing cascades. A length of 12 gauge wire approximately 7 feet long is bent to
form a U shape with the ends inserted in the container on either side of the
cascade plant. The ends of the wire frame to be inserted into the growing
container should be bent like hooks to prevent the wire from working loose. The
centre of the wire frame can be covered with 2 inch grid poultry wire. This will
allow the maximum area for tying down the new growth.

Training and Pinching: All new growth except the leading growing tips are
pinched when they have reached three or four leaf joints in length. All new
growth should be tied down regularly to the wire trellis to present as flat
appearance as possible. As buds form, pinching is stopped and you cascade placed
in an elevated position where the wire trellis can be slowly bent downward until
the desired cascading effect is reached. This usually takes about 1 week.

Insect Control: Establish a regular schedule of once a week spraying or
dusting with a good general purpose spray or Rose dust until buds show colour.
After this time dust lightly only, or flower injury may occur.
