Time
to think of winter protection where heavy frosts are experienced.
In
the summer rainfall areas, as there is now no prospect of rain for
the next eight months, start watering shrubs, roses, fruit trees and
vines. Many shrubs and trees are showing there autumn colours. The
stately Liquidambars are rich crimson with touches of scarlet, the
Tulip tree and the Maidenhair tree are pure gold this month, and in
some districts the apricot trees and Lombardy poplars are now a
golden yellow. But perhaps the most spectacular tree of all in autumn
is the Wax tree with its almost indescribable display of colours.
HARDY
SUMMER FLOWERING ANNUALS
Water
once a week during dry weather and feed once a month with liquid
fertiliser to maintain steady growth. Water in the morning in areas
that experience frost, so that the foliage has time to dry before
nightfall.
WINTER
FLOWERING ANNUALS
Feed
twice a month with liquid fertiliser. Remove faded flowers regularly,
especially from Iceland poppies, pansies and violas. Water during dry
weather, doing this in the morning in areas that experience frost.
Larkspur
and stocks:
If the lower leaves turn yellow this is a sign of nitrogen
deficiency. To remedy this give the plants a dressing LAN. Dissolve
60g of LAN in 5 litres of water and apply to a square metre. Do this
once a month for two or three months, or until the plants are healthy
and green again. Water before and after application.
Sweet
peas:
Tie the plants to their stakes or trellis as they grow, and remove
tendrils and side shoots so that nutrients are not wasted on
unnecessary growth. Increase the water supply as the plants grow.
Water at least once a week in the summer rainfall areas. Tidy up
plants as they die down, removing old flower stems and dead leaves.
Mulch with compost and water once a month in the summer rainfall
areas. Where plants were attacked by mildew during summer, spray
thoroughly with fungicide. Anemone japonica, Michaelmas daisy and
physostegia can still be lifted this month if they are overcrowded.
SUMMER
FLOWERING BULBS
Cannas:
Once the foliage has died back, cut the stems down to ground level.
In areas that experience frost cover the plants with a deep mulch of
coarse compost to protect the rhizomes.
Dahlias:
As soon as the foliage has died down, cut the stems down to 15 to
20cm. Tie all labels securely to the stems. If the tubers are to be
left in the ground in the summer rainfall areas cover them with a
deep mulch of coarse compost. If the tubers are to lifted and stored
for winter, first cut off the tails by pushing a sharp spade down
vertically into the ground about 15cm from the stems, then lift
carefully. The tubers can be placed in a trench in the garden and
covered with soil. If they are to be stored in boxes wash the soil
off, place the tubers in the boxes, cover with peat or sand and store
them in the garden shed. Water lightly from time to time during
winter. Do not store the tubers without any covering as they will
shrivel and be of no use next season.
Liliums:
When the foliage has died down, cut the stems off and cover the
plants with compost. Mark their positions with a ring of small
stakes.
Summer
rainfall areas:
Water agapanthus, day lilies and liliums at least once a month.
WINTER
FLOWERING BULBS
As
the bulbs come up water more frequently, about once a week in the
summer rainfall areas. Water narcissi, daffodils and other exotic
bulbs, which have not yet come up, about twice a month.
Warm
frost-free areas: These
bulbs can still be planted:
Allium neapolitanum
Anemone
coronaria
Aristea thyriflora (tall aristea)
Babiana
Bulbinella
latifolia (cat's tail)
Dipidax triquetra (star of the marsh)
Iris
(Dutch iris)
Freesia
Hyacinthus orientalis (hyacinth)
Ipheion
uniflorum (star of Bethlehem)
Ixia (wand flower)
Leucojum
(snowflake)
Lycoris radiata (spider lily)
Muscari botryoides
(grape hyacinth)
Narcissus
Ornithogalum thyrsoides
(chincherinchee)
Ranunculus asiaticus (ranunculus)
Schizostylis
coccinea (river lily)
Sparaxis (harlequin flower)
Tritonia
POT
PLANTS
Feed
calceolarias, cinerarias, cyclamen, daffodils, hyacinths, jonquils,
narcissi, poinsettias and primulas every two weeks with a liquid
fertiliser. Water about every three days or when the soil feels dry.
Discontinue feeding other pot plants if this has not already been
done. Water less frequently, but never let the plants, especially
ferns, orchids and philodendrons, become completely dry.
Once
the foliage of amaryllis , caladiums, achimes and tuberous rooted
begonias has died down, reduce watering to a light sprinkling from
time to time to prevent the soil becoming bone dry.
LAWNS
Winter
rainfall and warm frost-free areas:
Mow if necessary.
Summer
rainfall areas:
Water the grass about once a month.
SHRUBS
Take
hardwood cuttings:
Hardwood cuttings that were not taken last month can still be taken
now. These must be of fully matured wood, which developed in the past
spring or early summer. The cutting should be about 20 cm long after
the immature tips have been removed. Cut just below a node or leaf
joint. Remove the leaves from the bottom two thirds of each cutting.
Root the cuttings in the open ground. Make a v-shaped trench
in the garden about 15 cm deep and put a thin layer of sand at the
bottom. Dip the end of each cutting into a rooting hormone and then
position the cutting in the trench. Fill the trench with soil, firm
it well and then water. In the summer rainfall areas keep the soil
damp, but not saturated, during winter and early spring until the
summer rains starts. The cutting should be ready to plant in their
permanent position in the garden in the winter or early spring of
next year.
Protecting
from frost:
In areas where frost is experienced it is necessary to provide winter
protection for tender shrubs such as proteas, beloperones, cupheas,
daturas, fuchsias, hibiscus, poinsettias, etc.
Small shrubs
can be covered with large cardboard boxes. To protect large shrubs
place four stakes round each shrub and drape hessian over these every
night all through winter. Remove the boxes and hessian covers every
morning.
Protect the roots by covering the ground around the
plant with a deep mulch of compost or bark.
Summer
rainfall areas:
Water azaleas, camellias and all shrubs from the winter rainfall
areas once a week.
VEGETABLES
Water
vegetables regularly during dry weather. Feed with Multifeed P every
two weeks to improve the flavour of the vegetables.
In warm
frost-free areas spray tomatoes once a week against blight.
Asparagus:
Prepare trenches. Before preparing the trench clear the ground of
perennial weeds such as couch grass. Dig trenches any convenient
length but remember that the crowns must be spaced 45cm apart. Make
the trench 45cm wide and 25 to 30cm deep. Break up the ground at the
bottom of the trench then return the soil, mixing it well with plenty
old sifted compost and/or old, well-rotted manure and a dressing of
2.3.2. at the rate of 120g per metre of trench.
