During the peak months of summer and particularly July, the garden more often than not is in
need of water and it is important to monitor all perennials, shrubs and lawn to ensure they are
receiving a sufficient amount.
Hanging baskets, container plants and newly planted summer bedding plants are the most prone
to drought due to being shallow rooted. Shrubs and trees will be deeper rooted and will be able to
source their water supply from further down beneath ground level, that is providing the water
table level has not dropped too low from a prolonged period of dry weather.
There are two sources of water supply available for use in the garden and they are tap-water and
rainwater, the latter being natural and more beneficial as it contains no chlorides and has zero
hardness. However, when there is a limited supply of rainwater, then tap-water will be the only
Ponds and water-features this time of year can drop to a low level and will require the use of a
hose for a regular top up to maintain a sufficient level, this will also benefit any fish, particularly
with the addition of a spray attachment which will aid in aeration.
To maintain a lush green lawn during dry periods can be challenging and it is advisable to water
only once a week to minimise wastage. An excellent suggestion by the RHS is to place an empty
jam-jar on the lawn and with the sprinkler running for a sufficient time, that is until 13mm
(0.5inch) has collected at the bottom of the jar. This is the optimum amount before excess water is
wasted as the lawn has now received its required amount.
With regards to watering plants, it is more economical and efficient to use a watering can
compared to indiscriminate watering by a hose.
Water management is extremely important during periods of drought and the essence of this is the
method of water storage and harvesting. The most popular method by far is the use of water butts
positioned below downpipes which then take the run-off of rain water from various roofs such as
garden sheds, greenhouses or even the house. With the water butt raised up on blocks, the tap at
the base can be utilised to fill watering cans with the valuable stored rain water. The question then
is when is the best time to water the plants and lawn of the garden?
The blades of grass will hold moisture in the early hours of the morning, the moisture retreating
to the roots around midday. It is a general consensus that to avoid evaporation the best time to
apply water is in the morning or evening whilst avoiding the heat of the midday sun. The morning
application is the most favoured, this is because the ground will be drier as the day progresses
compared to the evening time, equating to a reduced chance of mildew diseases and the arrival of
slugs and snails.
The final question being: Is it best to water from the top, watering the leaves too, or from the
bottom and the roots only?
The jury is still out!
Summer bedding plants provide and create a temporary floral and foliage display during the
warm summer months. The form of display can be within the garden beds, hanging baskets or a
container of your choice. It is an excellent opportunity for one to become creative, not only with
the variety of plants available but, with also the type of container which can be used. For
example, a disused wheelbarrow or a pair of old boots can make authentic and attractive
Although grown from seed, they can be purchased in cellular trays and multi-packs ready for
planting and providing an almost instant effect.
The majority of the summer bedding plants are categorised as tender/half-hardy perennials,
hardy annuals, half-hardy annuals and hardy biennials. The following are some of the popular
- Sweet Peas
- Busy Lizzies
Generally, summer bedding plants are regarded as being frost tender and suitable for the
summer months only. They are excellent for filling any bare or vacant areas within the garden
beds, the larger areas can be planted with what is known as carpet bedding plants. Essentially,
these plants are more compact and closely integrated which give the effect of a carpet and it is
possible to create various different designs and patterns by using different colours of blossom.
This is widely seen in public gardens and commercial landscapes around the country where
many thousands of plants are used, the design layout being from a computerised plan.
The private garden does not have to be quite as formal, but an effective display can still be
achieved, whether the same colour is used in large clumps or long singular rows, it is another
opportunity to be creative in the garden.
Hanging baskets are a great addition for any garden or property and bedding plants with a
pendulous and trailing characteristic will create the best effect. Popular plants suitable for
hanging baskets are Lobelia, Begonia and Periwinkle, but, why not try the edibles of
strawberries and tomatoes.
Colour themes have long been popular and simple to achieve, this is known as monochromatic,
where each container or hanging basket is composed of plants with foliage or blossom in
shades of the same one colour. Again, another opportunity to be creative.
Regardless of the choice flowers and the location of planting, either within the borders or
container, the addition of summer bedding attributes to the garden a feeling of completion.
There will be minimal bare areas, a surrounding of flora with a profusion of colour and one must
not forget, a chance to be creative.
