HAVE quite a few exotic fruiting plants, including a boysenberry
vine which has sent out amazing runners along my iron boundary fence.
I wasn't able to cope with it over the summer, owing to a shoulder
operation, and now the suckers have rooted into the sandy soil.
Will they grow into productive plants if I cut them off and transplant
with a length of stem attached? I feed everything liberally with
horse manure and have tied most of the plant to the fence along
natural method of propagation, when a stem produces roots where
it comes in contact with the soil, is called layering. Given ideal
conditions, each piece can eventually become a productive plant,
though it will probably take two to three years before you get much
in the way of fruit.
Carefully dig up the
rooted stem and cut it into separate plants. Make sure you get the
"polarity" right - the roots should be on the end of the stem that
was closest to the original plant. And make sure each new plant
has at least two good strong buds.
Once they're established,
each winter cut the boysenberry shoots that fruited back to ground
level in summer, and tie young unfruited ones to the fence in their
And keep on using that
horse manure. Mixed in the soil for new plants, or as mulch around
established ones, it's great for most berryfruits.
