The Master Gardener Program
educates local gardeners on the art
and science of growing and caring
for plants. Trained Master Gardener
volunteers extend sustainable gardening
information to their communities
through educational outreach programs.
Summer is the time to enjoy
hanging baskets of flowers. Fuchsias,
geraniums, petunias, impatiens and
tuberous begonias grow beautifully in
hanging baskets and graciously spill
their color over the sides.
With a little care, they’ll bloom
for you all through the summer and into
the fall, according to Ross Penhallegon,
horticulturist with the Oregon State
University Extension Service.
“Remember that plants in
hanging baskets depend totally on you
to give them what they need to grow
and to stay healthy,” Penhallegon said.
First, hang them in the right
place. Fuchsias and tuberous begonias
like shade, or partial shade. Petunias
and geraniums flourish in full sun, and
impatiens prefer a cool, partially sunlit
location.
“Then make sure they are out
of the wind and that the baskets are
on a watering schedule so they will not
dry out,” Penhallegon recommends.
“Remember to feed and water the
baskets regularly.” It is best to water
at least once a day during most of the
growing season, and perhaps twice
during the hottest days.
Check moisture in the hanging
basket simply by poking your finger
deep into the middle of the pot. If
the soil feels dry, add enough water to
dampen all the soil and drip out of the
bottom of the basket.
Add any well-balanced soluble
fertilizer, such as 5-10-5, or a good
organic fertilizer, such as compost tea,
at least once a week to the water to keep
new flowers and foliage coming.
To increase the life and
blooming time of your hanging plants,
remove blooms after they begin to
fade. If you prune the vine, the cut will
create a new vine or branch to grow and
produce flowers. With care and good
pruning, baskets will produce flowers
until frost.
