SUMMER FLOWERS
The
spring bedding plants have given a great show, especially tulips and the cool
weather meant we enjoyed a long flowering season, but now it is time to start
replacing them with summer flowering plants. Winter flowering pansies can
continue to flower for a few more weeks, but they have been disappointing this
year as the cold weather stopped them bulking up into strong plants, so they
are destined for the compost heap.
When
removing old bedding plants from tubs and borders, keep bulbs and corms from tulips,
narcissus, crocus and hyacinths as they will flower again the following year.
However if they are still growing lift them carefully and replant them in good
soil to keep them growing for a few more weeks to build up a strong healthy
bulb. Once the foliage dies down lift them, dry them off and remove old soil,
leaves, and roots then store them in a dry place till autumn.
Summer
flowers can be grown from seed as annuals or half hardy annuals, or from corms,
tubers, bulbs or half hardy perennials like geraniums, which can be grown from
cuttings taken from the previous years bedding display. Impatiens, (Bizzie
Lizzies) can also be grown all year round as they root very easily from
cuttings and make nice house plants but they do suffer from red spider that is
very hard to eradicate with available chemicals.
Garden
Centres have a wide range of suitable plants for bedding to be purchased as
seed, small plugs or larger mature plants ready for immediate planting. Where
larger tubs or beds are to be mass planted it is a good idea to create a bit of
height with a few dot plants. Choose those with exotic foliage such as Canna,
Sweet Corn, Castor Oil plant, Eucalyptus, Brugmansias, Date Palm or Cordylines.
Some of these perennials which are not really hardy can be retained for another
year by lifting up at the end of the growing season and keeping them in a warm
place, or drying off for Cannas and Brugmansias.
Tubs and hanging baskets
Geraniums
and tuberous begonias are my favourites for tubs and large pots as I have big
plants that give a dazzling show. My geraniums have slowly been growing larger
from last autumn when I started them off as cuttings, and my begonias from
tubers were purchased about twenty years ago and although they have been split
up several times they are still quite large. These are supplemented with
African marigolds, Petunias, Impatiens and trailing Lobelia. The latter range
is also used for hanging baskets plus a central bright red or white geranium. Use
small plug plants for inserting through the sides of the basket as these are
less likely to get damaged.
Fuchsias
are perfect for hanging baskets as you can look up into the flowers which
always hang down. They can grow quite large so you only need one plant per
basket. Keep baskets and tubs watered and fed as they can be quite demanding
and respond to good treatment.
I have
one large tub that always gets a central dot plant to give it height.
Brugmansia is a favourite as its huge trumpet flowers are very bold and the
evening exotic scent is powerful.
Beds and borders
I use the
same range of bedding plants for my formal flower beds, but extend this range
with annuals sown from seed for bare patches of garden where I have been
renovating plants. We always seem to be buying a new special plant, so
something has to go to make room for it, and in its early years I like to add a
few bedding plants to brighten up the area. The cultivations and compost add
fertility to the soil at the same time. This year I had gaps after losing a
broom, Cytisus praecox and a Cistus Silver Pink.
Some
raised borders are a bit stony and dry so I grow some Livingston Daisies from
seed in cellular trays then plant direct when the plants are big enough. Keep
them watered to get them established.
I also
grow Cosmos in cellular trays for planting out when bigger.
Other
bare patches of soil get cultivated and sown with Shirley Poppies, Poppy
Ladybird and the fluffy pink Opium Poppy which makes a very bright splash of
colour.
Plant of the week
Euphorbia griffithii Fireglow is very useful for brightening up
the garden in late spring to summer when it produces its bright crimson
flowers. It is an herbaceous perennial that spreads by rhizomes just below the soil
surface. It is easy to grow as it likes most soils, partial shade, can tolerate
dry conditions, though it prefers a moist rich soil and grows about two feet
tall. Sometimes when given ideal conditions it can be quite invasive.
Take care
when handling the plant as it easily produces a milky sap when bruised which is
poisonous and can be very irritant in contact with skin.
