Best for patios… Verbena peruviana
‘Firehouse’ is perfect for hanging baskets and
containers because it forms a mound of flowers
that easily fills a hanging basket or patio planter.
What’s different about this verbena is that it
doesn’t cycle in and out of flowers – new flowers
open as the old ones die. The foliage is tough
and disease resistant, too. Place in a position
that receives morning sun and afternoon shade.
Baskets require daily watering in summer; containers,
every second to third day. Fertilise with a
liquid fertiliser for flowers twice a month. Plants
are available in eight different colours, including
purple fizz and lavender.
The Joburg Clivia Club Show
takes place on September
14 and 15 at Garden World
Nursery, Beyers Naudé Drive,

if you want to add to your
collection of clivia. Entry is
R20 per person over 12 years
of age. Contact Glynn at

Garden tasks for August
• Plant out summer annuals like salvias, marigold, bedding dahlias, gazanias, alyssum,
dianthus and mimulus. Water the plant twice a week and fertilise with a liquid
fertiliser once a month.
• Grow annuals from seed for a big splash of colour, such as marigolds, alyssum, cosmos,
cornflowers and lobelia as well as scatter packs, which are ready-made mixes of
summer annuals for sun or shade.
• Perennials that grow easily from seed include hollyhocks, Shasta daisies, asters,
scabious, statice, sweet William, aquilegia, Arctotis and foxgloves.
• Cut back or tidy up summer perennials to encourage new growth. Start watering
more regularly and fertilise with 5:1:5, 3:1:5 or 8:1:5.
• Feed irises with superphosphate. Cannas, daylilies, coreopsis and dahlias
can still be divided and replanted into well-composted soil.
• Amaryllis, daylilies and Louisiana irises can be planted from early September,
but wait until the middle of September to plant Crocosmia and dahlias.
• Keep watering spring-flowering bulbs and Liliums.
• Fertilise flowering shrubs with 5:1:5 or 3:1:5 and foliage shrubs with 3:2:1.
Trim winter flowering shrubs such as poinsettia.
• If you didn’t do so last month, scarify, aerate, fertilise and water the lawn.
Water once a week or every two weeks and mow weekly when necessary.
