The veggie patch
In the veggie garden
THE WARM WEATHER IS HERE! ROSES
ARE BLOOMING, CICADAS ARE
TRILLING AND EVERYTHING THAT
HAS WATER IS GROWING. IT IS TIME
TO PLANT ALL THE FROST SENSITIVE
PLANTS AND ECONOMISE ON THAT
PRECIOUS WATER. MULCH, MULCH,
MULCH – YOU HAVE HEARD IT BEFORE!
Lettuces of all types can still be grown
in summer. They all tend to get bitter
in the heat, due to a build-up of latex
type sap. The iceberg or heading types
may well bolt (flower) in October.
Bolting resistant types are available
but are seldom stocked by nurseries,
as they are very expensive.
Customers frequently comment at
my nursery that “It’s too late to plant
cabbages, cauliflower and broccoli,
isn’t it?” No, provided that you use
hybrid seedlings, these brassicas can
be grown year-round. Be warned
that the broccoli head (it’s a flower)
will mature very fast in the summer
heat. In just three days, it can go from
almost ready to showing the yellow
flowers. It is still fine to eat of course
but it doesn’t look quite right. If your
cauliflower heads are exposed to the
sun, they can get burnt, so tie the
leaves over them for protection.
It is tomato and capsicum (pepper)
season of course. You will need to
spray against late blight and maybe
early blight depending on the cultivar.
Staking is an advantage at this time of
year, especially once the rains start, as
it allows the plants to dry quicker and
reduces resulting in disease problems.
Brassicas will be attacked by aphids
and diamond-back moth larvae at this
time of year so you will need to spray
if you want a crop. Confidor® (active
ingredient imadacloprid) will work, as
will daily doses of soapy water.
Your onion crop will be maturing
in September or October. Once
the leaves start falling over, reduce
watering to just once a week. When
50per cent of them have fallen over,
the crop is mature. Stop watering
them and knock the remaining leaves
over to help them seal the bulbs. The
crop can be left in the ground until
the leaves have dried or they can be
lifted now and left to dry in the sun.
When storing, it is essential to choose
a cool, shady, dry place to either hang
the onions in bunches, or in orange
pockets. Do not allow them to get wet
in the rain.
Sow maize and sweet corn for green
consumption now. Sweet corn
matures quicker than maize - in about
80 to 90 days. Don’t sow maize first
because if it is allowed to pollinate
sweet corn, it will override the sweet
genes and you will get sweet looking
corn that tastes just like maize!
All the squashes, melons and other
cucurbits can be grown now too.
Space them 40 to 50cm apart and
watch out for powdery mildew.
