two grassed areas are the same and should be treated as such.
Meadow
Management
Once
in autumn (late August to September)
Once in early spring (late March to early April)
The cuttings
must be removed. This will make sure that the wildflowers
can grow. It will also prevent thistles, docks, brambles and
scrub from taking over.
The autumn
cut gives the meadow plants the best chance to flower and
set seed. However, traditional hay meadows can be cut in late
July. Farmers may also want to cut at this time to provide
hay for farm animals. The spring cut knocks back thistles
and vigorous grasses that may have taken hold over the winter.
Cutting
is flexible, allowing a great deal of control over the timing,
area and height of the cut. However, cutting a whole meadow
in one go can take away all the food needed by insects. So
leave some areas uncut for them. The best way to do this is
to cut the edges of your grassland in rotation. Leave a different
side uncut each year. A four metre margin is ideal.
Cutting
can be carried out with a variety of tools. This will depend
on the size of your meadow and what is available to you. On
a small meadow, in medium to long grass, hand sythes or a
power strimmer can be used. On a larger area long grass can
be cut for hay using a power sythe or a tractor drawn grass
cutter.

Wildflowers
When
and how should I plant?
The best
season for planting is Autumn. The plants can establish a
good root system through the Winter before facing competition
from existing vegetation in late Spring. The soft ground conditions
also facilitate planting. Spring planting is also usually
satisfactory. The small root volume of plug plants makes them
susceptible to desiccation so late Spring and Summer planting
should be avoided unless spot irrigation can be applied at
half litre per plant per week, should the need arise, after
planting until significant rain falls.
Plant
survival and growth rates are enhanced if plugs can be planted
into bare patches. Spraying small patches with glyphosate
or paraquat will create the desired gaps very quickly and
inexpensively. Alternatively the gaps can be created physically
using a spade or mattock. H. V. Horticulture have developed
a scuttion (a type of winged auger) which removes a disc of
turf to create a planting space for 2 to 3 plug plants. Experience
shows that if the mechanically or chemically cleared area
exceeds 30 cm in diameter then weed germination is likely
to be a problem. Planting speeds are typically over 100 plants
per hour.
Specialist
dibbers can be used to create a planting hole identical to
the shape of the module, thus ensuring good root to soil contact.
The dibber also creates a chet at the bottom of the planting
hole to encourage deep rooting.
Should
I plant a mix of plants or keep species together in groupings?
Choose
what ever planting arrangement suits but avoid planting in
straight lines.
Natural
meadows and pastures are a tapestry of different flowers,
with late flowering species succeeding early ones to maintain
a succession of colour with a plant density of 40/m2. It is
not economical to imitate this on any large scale. Plant sizes
and spacings in taller, mown meadows are much larger, the
texture is correspondingly coarser and more easily reproduced.
Begin with very few (3-5) species in irregular groups of varying
size and variable spacing both within and between groups use
plant densities of 3-5/m2, either in intermingled drifts or
in a complete mix species. Plant introductions can be increased
to 10-12/m2 and can include Spring and late Summer flowering
plants to spread the season.
Stronger
visual effect can be achieved from planting single species
drifts, clumps of plants can also look effective. Flowering
meadows often have a very heterogeneous mix of species. One
of the advantages of plants is the control offered over where
they are planted. Damper liking species can be planted in
the wetter areas, spring flowering plants can be planted together
so cutting can start earlier or very dense plantings can be
made to create a 'wild' herbaceous border.
How
can I use wild flower plants in naturalist settings?
Some examples
of species use by habitat are set out below:
Fertile
Grassland Meadow
In a fertile
grass area the taller and more vigorous wild flowers must
be used. Possible choices are the Oxeye Daisy (Leucanthemum
vulgare), Greater Knapweed (Centurea scabiosa) and Black Knapweed,
Meadow Cranesbill, Musk Mallow (Malva moschata) and Field
Scabious (Knautia arvensis) Other effective plants include
Tufted Vetch which can clamber over tall grass, Red campion
(Silene dioca) and Yarrow (Achillea milliefolium). Grass competition
and growth needs to be controlled in the establishment year,
the flowers actually use the long grass to provide support
for their rather leggy growth. Mixed planting creates an attractive
blend of white, blue and purple capable of maintaining appeal
from May to September.
Low
Fertility Calcareous Meadow
This low
mixed sward can be planted with some of the most attractive
wild flowers, many of which are important food sources for
butterflies. Examples are Birds Foot Trefoil (Lotus corniculatus),
Small Scabious (Scabious columbaria), Lady's Bedstraw (Galium
verum), Clustered Bell Flower (Campanula glomerata) and the
Knapweeds. Other attractive wild flowers which can be included
are Marjoram (Origanum vulgare), Thyme (Thymus drucei) Yellow
Toadflax (Linaria vulgaris), Selfheal (Prunella vulgaris)
and Harebell.
Acid
Grasslands
These
grasslands generally have less floralistic interest but important
species include Common Tormentil (Potentilla erecta), Heath
Bedstraw (Galium saxatile) along with Selfheal, Yarrow, Catsear,
Birds Foot Trefoil, Harebell, Meadow Buttercup and Sheep Sorrel
(Rumex acetosella)
Damp
and Wet Areas
Yellow
Flag Iris (Iris pseudacorus), Marsh Marigold (Caltha palustris)
and Purple Loosestrife (Lythrum salicaria) thrive in wet sites
and provide useful feature flowers at water margins. Cuckoo
flower (Cardamine pratensis), Sneezewort (Achillea ptarmica),
Devils Bit Scabious (Succia pratense) Meadow Sweet, Yellow
Meadow Vetchling (Lathyrus pratensis)., and Ragged Robin (Lychnis
flos-cuculi) are planted in drifts in damp grassland areas.
How
can I use Wild Flowers as components in a more formal landscape?
It is
possible to create a spectacular display by using restricted
colour schemes of one or a few species in clearly defined
blocks. Set out below are some design ideas that have proved
highly successful:-
Cowslip
Meadow
Cowslips
(Primal veris) can be planted into a lawn, which is kept mown
at 5 cm until late February/early March. Grass cutting is
stopped and the cowslips are allowed to flower for at least
six to eight weeks in April and May. Cutting can be started
after flowering is finished or in mid June to allow for seed
dispersal. Thereafter the lawn is cut as normal.
Red
Campion Hedgerow
A particularly
effective way to use Red Campion (Silene dioica) is to plant
along the edge of woodland and hedges. These vivid pink wild
flowers can create a solid mass colour in May and June. The
plants can be cut back any time after flowering.
Oxeye
Daisy Drifts
Oxeye
Daisy planted at 10/m2 will, within two years, create a dramatic,
highly visible and reliable block of white flowers from June
to August. The key to sustainability is to open up the grass
sward after the Autumn cut, for example by chain harrowing.
Other effective plants to use in solid drifts include Chicory
(Cichorium intybus) on dry sites, Toadflax, Musk Mallow (Malva
moschata), Greater and Black Knapweed, Field Scabious and
Meadow Cranesbill.
Primrose
Bank
Primroses
(Primula vulgaris) are shade loving and can be planted into
steep North and East facing grass banks or under dappled shade
(e.g. in an old orchard). Normal grass management is introduced
after flowering.
Wild
Flower Herbaceous Borders
Dense
plantings of wildflower plants will provide a long flowering
season, attract butterflies. require no weeding and will only
need to be cut down at the end of the season. At the front
of the bed spring flowering and the lower species are planted
such as Cowslips, Wild Thyme, Harebell, Birds Foot Trefoil,
Yellow Toadflax, Primrose, Lady's Bedstraw, Cuckoo Flower
and Small Scabious. In the Middle of the border are planted
Self Heal, Musk mallow, Yarrow, Red Campion, Devils Bit Scabious,
White Campion, Ragged Robin, Vipers Buglos, Water Avens, Purple
Loosestrife, Clustered Bellflower, Agrimony, Betony, Devils
Bit Scabious, Meadow Cranesbill. At the back of the border
the tallest plants are planted such as Oxeyedaisy, Greater
and Black Knapweed, Field Scabious, Chicory, and Meadowsweet.
Tufted Vetch will clamber over other species and makes an
excellent climber of low fences.
After
I have sown a wild flower and grassland seed cocktail, how
should I manage the site in the first year?
The first
year is all about cutting, this is used to control all the
annual weed which will germinate. Cut the grass down to 5
to 7 cm whenever the sward reaches 10 to 15 cm and if at all
possible remove the arisings. Do not expect or allow much
flowering in the first season. The first cut is the most important.
Err on the side cutting earlier rather than later and lower
rather than higher. It is a slow build to create a really
attractive wild flower grassland from seed.
How
should I manage the site in subsequent years?
In all
but the most infertile sites flowering grasslands need to
be cut. The grass growth needs to be controlled to allow the
flowers a chance to thrive. The minimum is a hay cut in late
July/early August. More typically this is followed by an aftermath
cut in the autumn. It is always preferable to remove the cuttings,
if they are left the thatch tends to swamp the wild flowers
and in the long term it can slightly lower the fertility of
the site. The area can be grazed in the from late summer through
to late autumn or even the following spring. In fertile soils
a cut (or graze) in the late spring or early summer, when
the grass growth is at its most vigorous, is very effective
in selectively weaken the grasses. The result is a shorter
sward and flowering is slightly delayed, so that the hay cut
can be taken slightly later. Introduce this early cut if your
site is prone to long grass which logdges.
Can
I have different mowing regimes on the site?
Experience
has shown that cutting paths through the flowering grass is
effective in providing access, offers a measure of control
over how people use the site and prevents the site looking
unkempt and forlorn.
There
are many other possible permutations of cutting, including
monthly mowing in the early or later part of the year to create
Summer or Spring meadows respectively. Some rougher areas
can be cut every other year to leave standing cover for over-wintering
insects. Finally as the sward develops and thickens some thought
should be given to gap creation, deliberate damage to the
surface approximating poaching by cattle, to allow new plants
to establish by seed and ensure the continued evolution of
the meadow community.
How
should I manage a site in the season after I have planted
wild flower plants into an established grass sward?
The young
plants have to compete against established grasses. It is
vital that the grasses are not allowed to swamp the young
plants. In the first spring and early summer it is vital that
when ever the grass reaches the height of 10 to 15 cm it is
cut back to 5 cm. The wild flowers will be un-effected by
being topped like this, the important thing is that the light
is not cut from them whilst they establish themselves. Failure
to take these cuts is one of the most important factors in
plant failure, the others being in-appropriate species selection
and drought after a late spring planting. The mowing regime
is kept up until late May early June in the first season and
is then relaxed, whilst the plants flower. A mid summer cut
is then taken i.e. late July/early August with a aftermath
cut in October.
How should
I manage a site in the season after I have planted wild flower
plants into an area, which has been seeded with a wild flower
grass mix as well?
Follow
the same regime as specified for a site just seeded with a
grass seed mix (see above) i.e. multiple cuts in the first
year.
In
the seasons after the wildflower plants are established how
should I manage the grassland site planted with wild flower
plants?
Follow
the same techniques as for a seed sown wild flower grassland
set out above. Using wild flower plants is much easier to
create specific areas for different cutting regimes. For example
if all the spring flowering plants are planted together the
after they have finished seed set the grass can be cut down
in late June and subsequently cut when required. This prevents
the grass dominating the flowers, keeps the grass short for
leisure uses and facilitates the flowering of shorter species
as a flowering lawn. Other areas can be planted with the late
summer flowering plants and the cutting made after they have
finished flowering, say August and if the grass tends to be
rather rank an earlier cut (i.e. in May) can be introduced
to keep the sward shorter.
Are
there any flowers that are sustainable without a cutting programme?
Provided
they are established successfully, then some species are much
more able to sustain themselves than others. In our experience
the following species can persist in low or no-maintenance
locations: Agrimony (Agrimonia eupatoria), Cow Parsely (Anthiscus
syvestris), Field Scabious (Knautia arvensis), Greater Knapweed
(Centaurea scabiosa), Black (Lesser) Knapweed (Centaurea nigra),
Meadow Cranesbill (Geranium prettiness), Musk mallow (Malva
moschata), Red campion (Silene dioca), Bladder Campion (Silene
vulgaris), Meadowsweet(Filiapendula ulmaia)
I want
to create a ecologically interesting woodland, how should
I set about doing it?
The details
of tree planting are easily available. Below are some short
notes that will help in planning your wood. The rest of this
section focuses on enriching existing woodlands with the field
layer of plants and flowers. This advice is targeted on introducing
wild flowers to planted woods, never for ancient wood lands.
Even when a new plantation is planted alongside there is very
little natural movement of woodland wildflowers (about 1 m
in 15 years) so introduction is necessary to create the field
layer of wild flowers. If at all possible try to plant a mix
of native tree species which reflects the natural woodland
that would be found in your neighbourhood if nature had been
left to evolve naturally. Advice on the native 'wild' wood
types is generally available from county ecologists and the
local Wild Life Trusts. Often they can specify the type as
a code number (e.g. W8 is an Ash Woodland). This information
can be used to draw up a list of species found in such woodlands
and the ratio of one to another (see Publications). The planting
should include trees, which will ultimately form the canopy,
and smaller trees and shrubs which will form the understory.
The field layer can only be introduced later when sufficient
shade is developed that grasses start to die out. Planting
of trees and shrubs should be at variable densities to increase
diversity. Much of the ecological interest of a wood occurs
ate the edge and especially on the south facing edge. Create
rides running East-West some 10 m wide, to maximise the length
of the South facing edge and to ensure that sunlight will
reach the bottom of the woodland edge. Rides should be curved
to prevent wind funnelling.
When can
I introduce field layer species such as bluebells?
Woodland
wild flowers are poor competitors against grass and normally
aim to achieve most of their growth, photosynthesis and flowering
in the spring, before the leaf canopy has opened. Woodland
wild flowers can be introduced when established trees, which
are at least five years old. Under medium to high shade levels,
where there is sparse or no existing site vegetation, conditions
are ideal for wild flower introduction. If there is some existing
vegetation then the introductions should be targeted into
the shadier, weed-free areas of the site.
Should
I introduce wild flowers as seed or as plants/bulbs?
Seed can
be highly effective in establishing woodland flora, provided
that the seed is available, viable and reasonably priced.
Plants are essential for species who mainly propagate vegetatively
or when more rapid results are required.
How can
I decide what species to introduce?
As with
wild flowers useful references are local woods, local floras
and ecologists. Soil samples and especially measurement of
the soil pH are extremely valuable (see Soil Analysis service).
Bluebells are rarely found in woods where the pH is above
7.5. The Wildflower Specifications page will help guide you
as will the page Wetlands and Woodlands species.
What
woodland seed mixes are available, what do they contain and
when should I sow them?
We at
Really Wildflowers have created three seed mixes, one for
acid soils, one for neutral soils and a third for calcareous
sites. The details of the number of seed per m2, the seed
rate and the cost are set out in Woodland seed mixes. No soil
preparation is required. Seeding can take place any time between
September and March.
What
species should I plant?
Plants
are used when quick results are needed (e.g. bluebells from
seed can take 5 years to reach the flowering stage), when
the seed is very expensive (e.g. primroses) or when the plants
principally propagate vegetatively (e.g. Wood Anemones). It
is better to plant small areas densely (e.g. 4 to 10 plants/m2)
than to lightly plant a large area (rare greater seeds are
produced - promoting second generation propagation). Planting
can be carried out any time from late August through to December
- with the exception of wild daffodils - which should be planted
before mid October because of the root initials they form
which can be damaged if planting occurs later. In addition
to the above species other species typical planted are Snowdrops
(both as a dry bulb and in the green), yellow Archangel, Wood
Sorrel, Ransom, Bugle, Ground Ivy , Nettle Leaved Bellflower
and ferns.
How
should a manage a woodland to encourage wildflowers?
Management
involves managing light and weeds.
Woodland
herbaceous species need light for continued survival and spread.
They respond to receiving light periodically so that flowering
is encouraged and seeds are set. When plantations reach the
thicket stage shrubs may be coppiced or standard trees thinned
to allow in more light.
In areas
with moderate to high light levels it is necessary to control
the growth of invasive weed species. The growth of some competitive
weed species e.g. Common Nettle (Urtica dioica), Cow Parsley
(Anthriscus sylvestris), Cleavers (Galium aparine), Brambles
(Rubus fruticosus agg.), Docks (Rumex spp.) and grasses, such
as Couch (Elymus repens), may need to be checked by cutting
in early and late Summer in the first two growing seasons
after introductions have been made. Only if the weed problem
becomes very bad will selective herbicides be necessary.
