Take fall cuttings to multiply your favorite plants
Taking cuttings
from favorite plants now will extend the season of fun in the garden, giving
you a project during the cold months.
Easy-to-root
perennials include: clematis armandii, coreopsis, salvia, geranium, coleus,
begonia, Mandeville, rosemary, sage, Joseph’s coat, sweet potato, figs, etc.
Cuttings both replace
and increase the plants in your garden. For example, even though Pineapple sage
and Mexican sage both return every year, the plants I grow from fall cuttings expand
the amount of hummingbird nectar available next spring and fall.
Generally
speaking, true annuals, started from seed, will not overwinter from cuttings, including
zinnias, lettuce, and marigold.

The number of cuttings
you should start is based on the amount of windowsill space or lighting you
have available. Most of us can make room for a dozen pots or rig up something
outside. One veteran gardener puts a single light bulb inside a container made
of old windows, creating a heated cold frame that keeps his starts safe from
freeze.
Prepare clean
containers by filling them with sterile potting soil to half an inch below the
rim. Use small pots or yogurt containers with drainage holes; large pots hold
too much moisture.
Soft stemmed
plants such as begonias and succulents will root well in a pot of damp
vermiculite or perlite. Softwood cuttings are rooted in peat moss, sand and
perlite.
Moisten the
rooting medium (soil, perlite, sand) and let it drain until damp. Sterilize the
cutting tool and working surface with alcohol or diluted bleach, if needed.
Work with a healthy
stem from the mother plant. Soft-stemmed plants such as chrysanthemums root
more quickly than woody stemmed ones such as boxwood. Newer growth is easier to
start no matter which plants you select.
Take a 4 to 6
inch cutting from the stem tip just below a leaf node. (A node is where the
leaf stems attach to the stem.) Remove flowers, buds and all the leaves except
the top two. If the top leaves are large, they can be cut in half to preserve
the plant’s energy.
Check the depth
of the rooting container against the length of your cutting. The cutting is
inserted into the soil deep enough so that the only part of the stem above the
soil is holding the leaves. Cut the stem so it fits the container but be sure
there are at least two leaf nodes in the soil.
Clear plastic
produce containers (berries, salad, etc.) with lids attached are useful for
short pieces and leaf propagation but keep the leaves away from the plastic.
Rooting products
cannot be re-used, so put a little of it into a separate container. Moisten the
stem and dip it into dry or liquid rooting hormone, then tap the stem to remove
any excess.
Insert the
cutting into a hole made with a pencil, and firm the soil. Put the pot onto
newspaper to continue to drain off excess moisture.
You can cover the
containers with plastic wrap or a clear plastic bag to prevent the cuttings
from drying out but lift the plastic daily to prevent disease. Keep un-rooted
cuttings in a warm place, away from direct light. When new growth emerges at
the top, roots have formed below.
The roots of your
new plants will emerge from the former leaf nodes on the bottom and sides of the
cuttings. Soil has to be checked daily to ensure correct moisture level – moist
not wet.
Transplant the
rooted starts into small pots and move them into bright light. Keep the plants
compact by pinching back new growth. As the roots continue to grow, the plants
can be moved to larger pots.
