than perfect pansies
HAVE been trying to grow violas and pansies in pots outside my front
door. It's shady but they get morning sun. I don't know what I'm
doing wrong - they're tall and straggly and the bottom leaves have
gone yellow. How much water do they need?
violas and pansies generally grow well in sun or light shade, too
much shade and dampness can cause the symptoms you describe. Yellow
lower leaves could indicate a lack of nutrients, mildew disease
or perhaps even an infestation of aphids. Check to see if aphids
are feeding under the leaves - if necessary you could spray with
Mavrik or Rogor 100 to control them.
You could also try moving
the pots into more light. In warm weather you'll need to water regularly,
perhaps every day. Remove spent flowers regularly too.
Alternatively, try planting
more shade-tolerant flowers such as mimulus (for spring-summer blooms),
or polyanthus or forget-me-nots (late winter to spring).
